Find The Value Of X.

Answers

Answer 1

The value of angle x in the intersecting chords is determined as  146⁰.

What is the value of angle x?

The value of angle x is determined by applying intercepting chord theorem for tangent angle at circumference of a circle.

The intercepting chord theorem, also known as the tangent chord theorem, states that when a tangent line intersects a chord of a circle at a point on the chord, then the measure of the angle formed by the tangent line and the chord is equal to half the measure of the intercepted arc (the arc that lies between the endpoints of the chord).

So if the tangent angle = 73⁰, the arc angle X = 2(73) = 146⁰

The findings of the research project suggest that regular exercise can be an effective tool for managing stress in university students.

What would be the research project?

A sample research project is given below:

Study of Data: The impact of exercise on stress levels in university students

Prediction: We predict that there will be a significant decrease in stress levels following a four-week exercise program.

Data Collection: Participants were recruited through flyers and social media. They were asked to complete a pre-test stress survey before beginning the exercise program, and a post-test stress survey after completing the program. The exercise program consisted of a combination of cardiovascular and resistance training, meeting three times a week for four weeks.

Using equations,

8. The original dimensions of the rectangle are:

Length = 6m and Width = 2m.

9. The meter contains the following:

Value of nickels = 0.63

Value of dime = 2.26

Value of quarters = 0.21

10. Volume of the sphere is V. So, the value of r will be:

r = ∛ (3v/4π)

11. Solving for the linear equation we can get the value of m = -1

Define equations?

A mathematical statement that has two expressions with equal values separated by the symbol "equal to" is called an equation.

In the question,

1. Let the length of the rectangle be = x.

Let the width of the rectangle be = w.

Given,

l = 3w

When the width is increased by 4 meters, (w + 4) meters is the width now.

Then, the rectangle becomes a square.

That means length and width are equal.

l = w+4

Using l from the 1st equation,

3w = w + 4

Subtracting w from both sides,

⇒ 3w - w = 4

⇒ 2w = 4

Diving both sides by 2,

⇒ w = 2 meters.

We know, l = 3w

l = 3 × 2

l = 6 meters.

2. Here,

Let nickels be n.

Let dimes be d.

Let quarters be q.

Given,

Triple the number of quarters as nickels, so:

3q = n

Solving this for q,

q = n/3

Dimes is one than double the times of nickels, so:

d = 2n + 1

Total value of coins = $3.10

So, n + d + q = 3.10

Substituting the value of q and d,

⇒ n + 2n + 1 + n/3 = 3.10

⇒ 3n + n/3 = 3.10 - 1

⇒ (9n+n)/3 = 2.10

⇒ 10n = 6.3

⇒ n =0.63.

We can now find,

d = 2n + 1

= 2 × 0.63 + 1

= 1.26 + 1

= 2.26

q = n/3

= 0.63/3

= 0.21

3. Given,

Volume of sphere,

V = 4/3 × π × r³

Solving for r,

Multiply 3/4 on both sides,

⇒ 3v/4 = π r³

Divide both sides by π,

⇒ 3v/4π = r³

Now, taking cube root on both sides we get,

r = ∛ (3v/4π)

4. Now given a linear equation,

[tex]y=-2x^{m+2}[/tex]

As the equation is a linear equation,

The value of (x, y) we can take as (0,0)

So, 1 = m +2

⇒ m = -1

Question: Write the equation of a line parallel to y = x -5 that goes through (7,0).

Answers

To find the equation of a line parallel to y = x - 5 that goes through (7,0), we need to use the fact that parallel lines have the same slope.

The slope of the line y = x - 5 is 1, since the coefficient of x is 1. Therefore, the slope of the parallel line we want to find is also 1.

Using the point-slope form of a line, we can write the equation of the parallel line as:

y - y1 = m(x - x1)

where (x1, y1) is the point (7,0) and m is the slope of the line, which we know is 1.

Plugging in the values, we get:

y - 0 = 1(x - 7)

Simplifying, we get:

y = x - 7

Therefore, the equation of the line parallel to y = x - 5 that goes through (7,0) is y = x - 7.

Answer:

y = x - 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x - 5 ← is in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes , then

y = x + c ← is the partial equation

to find c substitute (7, 0 ) into the partial equation

0 = 7 + c ( subtract 7 from both sides )

- 7 = c

y = x - 7 ← equation of parallel line

Write the equation for the line through the given Q-points in slope-intercept form.

As a result, the slope-intercept form equation for the line through points (5, 21) and (11, 3) is:

y = -3x + 36

Therefore, the equation of the line through (4, 8) and (12, 20) in slope-intercept form is:

y = (3/2)x + 2

The slope of the line must first be determined using the following formula to determine the equation of a line through two points in slope-intercept form:

slope[tex](m) =\frac {(y2 - y1)}{(x2 - x1)}[/tex]

where the coordinates for two points are (x1, y1) and (x2, y2).

The line's slope-intercept form is thus applicable, and it is as follows:

y = mx + b

where b is the y-intercept and m is the slope that we just discovered.

We possess

slope [tex](m) = \frac{(3-21)}{ (11-5)}[/tex],

m = -3

So, using one of our points, we can determine b:

Answer:

The vertex of the quadratic function f(x) = -2x^2 + 8x is (2, 8).

Step-by-step explanation:

To find the vertex of the quadratic function f(x) = -2x^2 + 8x, we first need to find the x-coordinate of the vertex using the formula:

x = -b / 2a

where a = -2 and b = 8. Substituting these values, we get:

x = -8 / 2(-2) = 2

Now, to find the y-coordinate of the vertex, we can substitute this value of x back into the equation: f(2) = -2(2)^2 + 8(2) = 8

if a sample of shoppers showed stating that the supermarket brand was as good as the national brand, what is the p-value (to decimals)?

Answers

The p-value is  0.046, or 4.6% if a sample of shoppers showed stating that the supermarket brand was as good as the national brand.

To calculate the p-value, we use null and alternative hypotheses, as well as the test statistic and its distribution under the null hypothesis.

By the null hypothesis, we can say that supermarket brands are as good as national brands, and by the alternative hypothesis, we can say that supermarket brands are not as good as national brands.

This hypothesis can be tested by performing a two-tailed z-test for proportions.

In a sample of n shoppers, say that x shoppers say that supermarket brands are as good as domestic brands. The sample percentage can be calculated as follows:

p hat = x/n

in the null hypothesis, the  sample proportion is equal to the hypothesized proportion, that is 0.5

The test statistic for a two-sided z-test for proportions is given by:

z = (p-hat - p0) / sqrt(p0(1-p0)/n)

where p0 is the hypothesized proportion under the null hypothesis.

In this case, we have:

p-hat = 0.5

p0 = 0.5

n = sample size

The null hypothesis states that the supermarket brand is as good as the national brand, so we would expect the proportion of shoppers who state this to be 0.5.

If the test statistic z falls in the rejection region (i.e., if |z| > 1.96 for a significance level of 0.05),

we would reject the null hypothesis and conclude that there is evidence to suggest that the supermarket brand is not as good as the national brand.

If the test statistic falls in the non-rejection region (i.e., if |z| <= 1.96 for a significance level of 0.05),

we would fail to reject the null hypothesis and conclude that there is insufficient evidence to suggest that the supermarket brand is not as good as the national brand.

To calculate the p-value, we need to find the probability of getting a test statistic as extreme or more extreme than the one we observed, assuming the null hypothesis is true.

For a two-tailed test, the p-value is twice the observed area of ​​the tails above the absolute value of the test statistic.

Assuming the sample size is large enough, the distribution of the test statistic can be approximated as a standard normal distribution under the null hypothesis.

Suppose in a sample of 100 shoppers, 50 said that supermarket brands are as good as domestic brands. after that:

p hat = 0.5

p0 = 0.5

n=100

The test statistic is:

z = (p hat - p0) / sqrt(p0(1-p0)/n) = 0 / sqrt(0.5 * 0.5 / 100) = 0

The p-value is the probability that the test statistic is extreme or more extreme than 0. This is the probability of getting further away from the 50/100 ratio or 0.5 in either direction.

p-value = P(p hat <= 0.4 or p hat >= 0.6) = 2 * P(p hat <= 0.4) = 2 * P(Z <= ( 0.4 - 0.5) / sqrt (0.5 * 0.5 / 100) ) = 2 * P(Z <= -2) ≈ 0.046

where Z is a standard normal random variable.

Therefore, the p-value is approximately 0.046, or 4.6%.

Answers

Simon needs approximately 48.6 gallons of gas for his trip from Orlando, FL to Sacramento, CA.

To calculate the number of gallons of gas Simon needs for his trip, you can use the following formula:

Gallons = Miles / Miles per gallon

First, convert the distance of 2,804 miles to miles per gallon by dividing by the car's average mileage per 2

gallons:2,804 / 48.6 = 57.75 mpg

Then, use this value to calculate the number of gallons of gas Simon needs for his trip:

Gallons = Miles / Miles per gallon

Gallons = 2,804 / 57.75

Gallons ≈ 48.6 gallons

Therefore, Simon needs approximately 48.6 gallons of gas for his trip from Orlando, FL to Sacramento, CA.

The answer should be rounded to the nearest tenth, so the final answer is 48.6 gallons.

What fraction do you get from putting together 8 copies of the unit fraction 1/2? Explain how you found the numerator.

Answers

When you put together 8 copies of the unit fraction 1/2, you are essentially adding 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2.

To add fractions, you need to make sure the denominators are the same. In this case, all the fractions already have the same denominator of 2.

So, we can add the numerators together:

1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 + 1/2 = 8/2

Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:

8/2 = 4

Therefore, putting together 8 copies of the unit fraction 1/2 gives us a fraction of 4/1, or simply 4.

The absolute value equation that has the solution set with digits -18, 0, and X on a number line is :

|X| = X if X ≥ 0

|X| = -X if X < 0

What do you mean by term Equation?

An equation is a mathematical statement that shows the equality of two expressions. It typically includes one or more variables (represented by letters) and may also include constants, coefficients, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation.

If the solution set for the absolute value equation has digits -18, 0, and X on a number line, then the equation must have two separate cases: one where X is positive and one where X is negative. We can write the absolute value equation as:

|X| = X for X ≥ 0

|X| = -X for X < 0

To include the values -18 and 0 in the solution set, we need to check each case separately:

|X| = X if X is greater than 0 or zero. The equation X = a must therefore be resolved, where an is either -18 or 0. As X 0 is satisfied by only one value in the solution set, the case's solution is X = 0.

Example 2: X < 0

When X is negative, |X| equals -X. So, we must find a, where an is either -18 or 0, to solve the equation -X = a. This case's solution is X = 18, as it is the only value in the solution set that satisfies the condition X 0.

As a result, the absolute value equation whose answer is represented by the numbers -18, 0 and X on a number line is:

|X| = X if X ≥ 0

|X| = -X if X < 0

or

|X| = 0 if X = 0

|X| = 18 if X < 0

therefore mean is 7.1

Median:

Arranging them in Ascending or descending order, we get:

The missing length is 8m which is option A.

Length calculation.

To find the missing length, we need to use the formula for the area of a rectangle:

area = length x width

We are given the area as 114 m² and the width as 15 m. Let's substitute these values into the formula:

114 = length x 15

Solving for length, we get:

length = 114/15

O(0,3) form a triangle. Find the desired slopes and lengths, then fill in the words that characterize the triangle.

Answers

Based on the lengths of the sides, we can see that the triangle is scalene. Based on the slopes of the sides, we can see that the triangle is acute since all the slopes are negative or less than 1.

What is triangle?

A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.

To find the desired slopes and lengths of the triangle formed by the points M(-7, 8), N(-1, 9), and O(0, 3), we can use the distance formula and the slope formula.

Distance formula:

The distance between two points (x₁, y₁) and (x₂, y₂) is given by:

d = √((x₂ - x₁)² + (y₂ - y₁)²)

Using this formula, we can find the lengths of the sides of the triangle:

Length of MO:

d(MO) = √((0 - (-7))² + (3 - 8)²) = √(7² + 5²) = √(74)

Length of NO:

d(NO) = √((-1 - (-7))² + (9 - 8)²) = √(6² + 1²) = √(37)

Length of MN:

d(MN) = √((-1 - (-7))² + (9 - 8)²) = √(6² + 1²) = √(37)

Slope formula:

The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:

m = (y₂ - y₁) / (x₂ - x₁)

Using this formula, we can find the slopes of the sides of the triangle:

Slope of MO:

m(MO) = (3 - 8) / (0 - (-7)) = -5/7

Slope of NO:

m(NO) = (9 - 8) / (-1 - (-7)) = 1/6

Slope of MN:

m(MN) = (9 - 8) / (-1 - (-7)) = 1/6

Characterization of the triangle:

Based on the lengths of the sides, we can see that the triangle is scalene (no two sides have the same length). Based on the slopes of the sides, we can see that the triangle is acute (all angles are less than 90 degrees) since all the slopes are negative or less than 1. Additionally, we can see that the side MO is the longest side of the triangle, and since the slope of MO is negative, we can conclude that the angle opposite side MO is the largest angle in the triangle.

Write a polynomial f(x) that satisfies the given conditions.
Polynomial of lowest degree with zeros of -4(multiplicity 1) 1( multiplicity 2)and with F(0)=-12

Answers

If -4 is a zero with multiplicity 1, then (x + 4) is a factor of the polynomial. Similarly, if 1 is a zero with multiplicity 2, then (x - 1)^2 is a factor of the polynomial. Therefore, we can write the polynomial in factored form as:

f(x) = a(x + 4)(x - 1)^2

where "a" is a constant that we need to determine.

To find "a", we use the fact that f(0) = -12. Substituting x = 0 into the equation above, we get:

f(0) = a(0 + 4)(0 - 1)^2

-12 = -4a

Solving for "a", we get:

a = 3

Therefore, the polynomial is:

f(x) = 3(x + 4)(x - 1)^2

Note that this polynomial has a zero at x = -4 (with multiplicity 1), a zero at x = 1 (with multiplicity 2), and f(0) = -12.

Answers

Bianca practiced 28 hours a day whereas Filipe practiced 12 fewer hours than Bianca, if Filipe practiced for 16 hours

below are the situations and the operations used

Rising =  +

difference = -

to find the part of the grand total= ÷

Sharing  or Grouping = *

Since "Filipe trained 12 hours less than Bianca" and "Filipe trained 16 hours", we can use rising(+) to find the amount of time Bianca trained.

it is calculated by using the following formula

Bianca's training time = Filipe's training time + 12

Bianca practice hours = 16 + 12

Bianca Practice Hours = 28

So Bianca practiced 28 hours a day.

The central angle ABC and central angle DEF are both right angles.

Do you think the LENGTH of the intercepted arc will have the same measurement? Why or Why not?

Answers

Answer:

Yes, the length of the intercepted arc will have the same measurement. When a central angle intercepts an arc of a circle, the measure of the angle is equal to the measure of the intercepted arc. In this case, both angles ABC and DEF are right angles, which means that they each intercept half of the circle. Therefore, the length of the intercepted arcs will be the same.

Answers

we use the definition of supplementary angles again to conclude that ∠3 and ∠5 are supplementary.

To prove that ∠3 and ∠5 are supplementary, we can use the following steps:

Given: w ∥ x and y is a transversal.

∠1 ≅ ∠5 by the corresponding angles postulate.

By definition, ∠3 and ∠1 are a linear pair, so they are supplementary.

Therefore, m∠3 + m∠1 = 180 by the definition of supplementary angles.

Substituting m∠5 for m∠1, we get m∠3 + m∠5 = 180.

Therefore, by the definition of supplementary angles, ∠3 and ∠5 are supplementary.

In step 1, we use the corresponding angles postulate, which states that when two parallel lines are cut by a transversal, the pairs of corresponding angles are congruent. In step 2, we use the definition of a linear pair, which states that when two angles form a line, they are supplementary. In step 3, we use the definition of supplementary angles, which states that the sum of two supplementary angles is 180 degrees. In step 4, we substitute m∠5 for m∠1, since we know that ∠1 ≅ ∠5. Finally, in step 5, we use the definition of supplementary angles again to conclude that ∠3 and ∠5 are supplementary.

Answers

The problem involves a line segment divided into two parts in a specific ratio. The ratio of the length of the lesser part to the length of the greater part is found to be (√2 - 1).

Let the length of the whole line segment be x, and let y be the length of the greater part. Then the length of the lesser part is (x - y).

According to the problem statement, the ratio of the lesser part to the greater part is the same as the ratio of the greater part to the whole. Mathematically, we can write this as:

(x - y)/y = y/x

Simplifying this equation, we get:

x^2 - y^2 = y^2

x^2 = 2y^2

Taking the square root of both sides, we get:

x = y√2

Therefore, the value of the ratio of the lesser part to the greater part is:

(x - y)/y = (√2 - 1)

So, the answer will be (√2 - 1).
