Answer:

BC ≈ 14.4 mm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

BC² = AB² + AC² = 2.6² + 14.2² = 6.76 + 201.64 = 208.4

Take the square root of both sides

BC = [tex]\sqrt{208.4}[/tex] ≈14.4 mm ( to 1 dec. place )

There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square.

quadratic equations

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).

factoring

factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.

The height of the screen will be;

⇒ h = 28 inches

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

A flat screen television is a rectangle with a 53-invh diagonal and a width of 45 inches.

Here,

The diagonal of the screen television = 53 inches

And, The width of the screen television = 45 inches

Let the height of the television = h

So, By the Pythagoras theorem, we get;

⇒ AC² = AD² + DC²

Where, AC = Diagonal of television.

AD = Height of the television

DC = Width of the television.

Substitute all the values, we get;

⇒ 53² = h² + 45²

⇒ 2809 = h² + 2025

⇒ 2809 -2025 = h²

⇒ h² = 784

⇒ h = √784

⇒ h = 28 inches

Thus, The height of the screen = 28 inches

Answer:

y = 95°

Step-by-step explanation:

x + 120° = 180°

x = 180° - 120°

x = 60°

25° + y + x = 180°

Domain

Range

Interval Notation

Let's organize what is given to us from the problem.

We are given a graph of a function.

We need to analyze the graph to determine the domain and range of the graph.

If we take a look at our x values, we see that our graph starts at x = 3 and continues infinitely.

∴ we can write the graph's x-values as [3, ∞), or x ≥ 3.

⇒ The domain of the graph is equal to x ≥ 3.

If we take a look at our y values, we see that our graph begins at y = 1 and also continues infinitely.

∴ we can write the graph's y-values as [1, ∞), or y ≥ 1.

⇒ The range of the graph is equal to y ≥ 1.

∴ the answer to the question is equal to:

A. D: x ≥ 3

    R: y ≥ 1

When Merida divides her age by 3 and adds 5, the result is 9, now the equation becomes: 9 = (m + 3) ÷ 5.

The link between two expressions on each side of the sign is represented by a mathematical equation. One variable and an equal sign are often present.

The definition an equation in algebra is a mathematical expression that indicates the equivalence of two mathematical terms. In equation 6x + 11 = 14, for instance, the two expressions 6x + 11 and 14 are separated by the symbol "equal."

When Merida divides her age by 3 and adds 5, the result is 9, now the equation becomes: 9 = (m + 3) ÷ 5, this represents the situation where m is Merida's age.

The factored form of quadratic equation 2x² + 7x + 3 is 2(x + 1/2) (x + 3)

A quadratic equation can be expressed in:

- Standard form: y = ax² + bx + c

- factored form: y = a(x - x₁) (x - x₂)

Here, x₁ and x₂ are the roots of the given function.

Suppose we are given a quadratic equation:

y = ax² + bx + c

To find the factored form, use the following properties:

x₁ . x₂ = c/a

x₁ + x₂ = - b/a

In this case, the quadratic function is:

y = 2x² + 7x + 3

We have to find x₁ and x₂ such that:

x₁ . x₂ = 3/2

x₁ + x₂ = - 7/2

Hence,

x₁ = - 1/2

x₂ = - 3

Therefore the factored form is:

y = 2(x + 1/2) (x + 3)

Answer:

36 candy bars. (32 if sold in packs)

Step-by-step explanation:

We know that eight candy bars cost 6 dollars, and we purchased $27 dollars worth of them.

Therefore, we can use 27/6 = 4.5 to see how many packs/sets of candy bars we purchased. Since there are 8 in a pack/set, we do 8x4.5 = 36 to see we can purchase 36 candy bars. However, if you can only buy them in packs of 8, then you can only purchased 4 packs/32 bars since 6x5 = 30 and we only have 27 dollars.

The height of the building is approximately 24.19 feet.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

Given that, place a 29-foot ladder against the top of a building and the bottom of the ladder is 16 feet from the bottom of the building.

So, hypotenuse of the triangle is 29 feet and base of the triangle is 16 feet.

Let h be the height of the building.

Now, 29²=16²+h²

841=256+h²

h²=841-256

h²=585

h=24.19 feet

Therefore, the height of the building is approximately 24.19 feet.

Answer:

1. 3/8 2. 3/8 3.  3-/8  4.  3/8 or  0. 375

Step-by-step explanation:

The relationship between the variables in the table is an inverse variation The equation to model is y = 42/x.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 8 is an equation.

We have,

x:  2  6  7  14

y: 21  7  6  3

Now,

When x = 2, y = 21

This can be written as,

y = kx

21 = 2k

k = 21/2

The equation is y = (21/2)x _____(1)

or

y = k/x

21 = k/2

k = 42

The equation is y = 42/x _____(2)

Now,

We will check which equation fits the table.

From (1)

y = (21/2)x

When x = 6,

y = (21/2) x 6 = 21 x 3 = 63

From (2),

When x = 6,

y = 42/6 = 7

When x = 7,

y = 42/7 = 6

When x = 14,

y = 42/14 = 3

This equation satisfies the table.

Thus,

The relationship is an inverse variation.

The equation is y = 42/x.

Answer:

72,000kg

Step-by-step explanation:

So, we know that there are 640 bags.

Each bag has a mass of 120kg.

The mass shrinks at a ration of 15:16

So, we can think of the total mass as 120x640:

120*640

=

76,800kg

Next, we can think of the dried mass as 15/16 of the 76,800kg. This is because the dried ration was 15, and the orgninal ration was 16:

76,800/16

=

4,800kg

This isnt our end answer, next we have to multiply this by  15, to find the dried ration:

4,800*15

=

72,000kg

Answer:

Step-by-step explanation:

You want to find the measure of the angle designated as ∠1, given the other two have measures of 40° and 30°. You also want the classification of the triangle based on its angles.

The sum of angles in a triangle is 180°.

  40° +∠1 +30° = 180°

  ∠1 = 110° . . . . . . . . . . . . subtract 70°

The classification of a triangle as acute, right, or obtuse is based on the measure of its largest angle. If that angle is 90°, the triangle is a right triangle. If it is less, the triangle is acute; if it is more, the triangle is obtuse.

The angle measure 110° is more than 90°, so this triangle is an obtuse triangle.

The worded problem translates to n  ≤ 3

The options that are solutions to the problem are 1 and 4:

1) n less than or equal to 3, and

4) 3 greater than or equal to n   (since 3 ≥ n)

Step-by-step explanation:

Let's translate the e=words into expressions:

"five plus two times a number n"  becomes 5 + 2n

"is less than or equal to eleven" becomes ≤ 11

Put the two expressions together, with the word "is" and the "=" sign:  

     5 + 2n ≤ 11

Solving:  

   2n  ≤ 11 - 5

   2n  ≤ 6

   n  ≤ 3

The options are:

1) n less than or equal to 3   Correct

2) 3 less than or equal to n   Incorrect.  3 is greater than or equal to n

3) n less than or equal to 8   Incorrect.  n is less than or equal to 3
