Can you help me with the question in the photo attached below and remember read it first?

Answer:

Let the height be represented as x

width = 14 + x

Length of diagonal = 34 inches.

Taking one diagonal of the rectangle to form a triangle.

using the Pythagoras theorem.

34² = (14 + x)² + x²

1156 = 196 + 28x + x² + x²

2x² + 28x - 960 = 0

divide through by 2

x² + 14x - 480 = 0

x² + 30x - 16x - 480 = 0

x(x + 30) - 16 (x + 30) = 0

(x - 16) = 0 or (x + 30) = 0

x = 16 or x = - 30

since the length can't be negative

therefore 16 inches is correct

The indicated derivatives in the question can be found to be :

To find the derivative of e^(x^3) + log_3(pi) with respect to x, we apply the rules of differentiation to each term:

Using the chain rule, we have:

d/dx (e^(x^3)) = e^(x^3) x (3x^2)

The derivative of log_3(pi) is 0, because log_3(pi) is a constant and the derivative of a constant is 0.

So, the derivative of the entire expression is:

d/dx (e^(x^3) + log_3(pi)) = e^(x^3) x 3x^2 + 0 = 3x^2 x e^(x^3)

To find the derivative of (x^(1/6))^ln(x) with respect to x, we first simplify the expression by using the power rule of logarithms:

(x^(1/6))^ln(x) = x^(ln(x)/6)

Now, we find the derivative of x^(ln(x)/6) using the chain rule:

d/dx (x^(ln(x)/6)) = (ln(x)/6) × x^((ln(x)/6) - 1) × d/dx (x)

The derivative of x is 1, so:

d/dx ((x^(1/6))^ln(x)) = (ln(x)/6) × x^((ln(x)/6) - 1) × 1 = (ln(x)/6) × x^((ln(x)/6) - 1)

The expressiοn that shοws the result οf that transfοrmatiοn intο the bοx under it are  [tex]f(x) - 4 = 3^{x} - 4[/tex]

In mathematics, a transfοrmatiοn refers tο a prοcess οr οperatiοn that changes the pοsitiοn, shape, οr size οf a geοmetric figure οr οbject in a cοοrdinate plane οr space. Transfοrmatiοns can be classified intο several types, including translatiοns, reflectiοns, rοtatiοns, dilatiοns, and cοmbinatiοns οf these.

Each type οf transfοrmatiοn invοlves a set οf rules οr fοrmulas that define hοw the οriginal οbject οr figure is transfοrmed intο a new οne. Transfοrmatiοns play an impοrtant rοle in many areas οf mathematics and science, including geοmetry, linear algebra, cοmputer graphics, and physics.

given functiοn : [tex]f (x ) = 3^{x}[/tex]

fοr transfοrmatiοn, we need tο replace value οf x by the value given in different parts.

part 1 :

-4 f(x) = ?

we have [tex]f (x ) = 3^{x}[/tex]

sο,  -4 ×  f (x ) = -4 × [tex]3^x[/tex]

∴  -4 f(x) =  -4 × [tex]3^{x}[/tex]

part 2 :  

f(-4x) = ?

we have f (x ) = [tex]3^{x}[/tex]

replacing value οf x by -4x,

∴  f(-4x) = [tex]3^{-4x}[/tex]

part 3

: f(x-4) = ?

we have [tex]f (x ) = 3^{x}[/tex]

sο, replacing value οf x by x-4,

∴[tex]f(x-4) = 3^{x-4}[/tex]

part 4 :

f(x) - 4 = ?

we have [tex]f (x ) =3^{x}[/tex]

The probability of exactly 3 out of 10 vehicles exceeding the speed limit on US 131 is 0.250.

This problem can be solved using the binomial distribution. We are given that the probability of any given vehicle exceeding the speed limit is p = 0.6, and we are interested in the probability of 3 out of 10 vehicles exceeding the speed limit, i.e., X = 3.

The probability mass function of the binomial distribution is given by:

P(X = k) = (n choose k) ×p^k ×(1-p)^(n-k)

where n is the number of trials, k is the number of successes, p is the probability of success, and (n choose k) is the binomial coefficient, which is equal to n!/(k! (n-k)!).

Substituting the given values, we get:

P(X = 3) = (10 choose 3) × 0.6³ ×0.4⁷

P(X = 3) = 0.250

Therefore, the probability of exactly 3 out of 10 vehicles exceeding the speed limit on US 131 is 0.250, rounded to three decimal places.

It is expressed as a number between 0 and 1, where 0 represents an impossible event (i.e., it will never happen), and 1 represents a certain event (i.e., it will always happen).

There are a total of 8 cans of soft drinks, and the child chooses 4 cans to arrange in a row. The total number of ways to choose 4 cans out of 8 is:

C(8,4) = 8! / (4! * 4!) = 70

(a) To find the probability that all four cans are diet drinks, we need to count the number of ways to choose 4 cans that are all diet drinks. Since there is one diet drink for each brand, there are 4 choices for the first can, 3 choices for the second can, 2 choices for the third can, and 1 choice for the fourth can. Therefore, the number of ways to choose 4 cans that are all diet drinks is:

4 * 3 * 2 * 1 = 24

The probability of choosing all diet drinks is then:

P(all diet drinks) = 24 / 70 ≈ 0.343 or about 34.3%

(b) To find the probability that the first two cans are diet drinks and the second two cans are regular drinks, we can count the number of ways to choose 2 diet drinks out of 4 and the number of ways to choose 2 regular drinks out of 4, and then multiply these two numbers together. There are:

C(4,2) = 4! / (2! * 2!) = 6

ways to choose 2 diet drinks out of 4, and also 6 ways to choose 2 regular drinks out of 4. Once we have chosen the 2 diet drinks and 2 regular drinks, there are 4! ways to arrange them in a row. Therefore, the total number of arrangements that have the first two cans as diet drinks and the second two cans as regular drinks is:

6 * 6 * 4! = 288

The total direct labor hours for each product to get the total direct labor hours required for the projected sales during the coming year.

To determine the contribution margin per direct-labor hour expended on each product, you will need to calculate the contribution margin for each product and divide it by the number of direct labor hours required to produce that product.
Contribution Margin = Sales Revenue - Variable Costs
Once you have calculated the contribution margin for each product, you can divide it by the number of direct labor hours required to produce that product to get the contribution margin per direct-labor hour.
To prepare a schedule showing the total direct labor hours that will be required to produce the projected sales during the coming year, you will need to estimate the number of units that will be sold for each product and the number of direct labor hours required to produce each unit.

Multiply the number of units by the number of direct labor hours per unit to get the total direct labor hours required for each product.

Contribution Margin = $40 - $20 - $5 - $3 = $12

Direct Labor Hours per unit = 2

Contribution Margin per Direct-Labor Hour = $12 / 2 = $6 MMK YU GHTJUIO7U

Contribution Margin = $60 - $25 - $10 - $5 = $20

Direct Labor Hours per unit = 4

Contribution Margin per Direct-Labor Hour = $20 / 4 = $5

Contribution Margin = $80 - $30 - $15 - $10 = $25

Direct Labor Hours per unit = 5

Contribution Margin per Direct-Labor Hour = $25 / 5 = $5

To prepare a schedule showing the total direct labor hours that will be required to produce the projected sales during the coming year, we need to estimate the number of units that will be sold for each product and the number of direct labor hours required to produce each unit.

For the givn steam and leaf plot, the mean= 11.61 and the median = 7.

What is mean?

In mathematics, the mean is a measure of central tendency of a set of numbers. It is also known as the average.

To find the mean of the data represented by the stem and leaf plot, we need to first determine the actual values represented by the plot.

The stem and leaf plot indicates that we have the following values:

For stem 1: 0, 0, 2, 8

For stem 3: 1, 7, 9

For stem 5: 0, 5, 7, 7, 7

For stem 11: 3, 4, 6

For stem 22: 3

For stem 23: 5

For stem 31: 0, 2, 9

To calculate the mean, we add up all these values and divide by the total number of values.

There are a total of 18 values, so:

(1x4 + 3x3 + 5x5 + 11x3 + 22x1 + 23x1 + 31x3) / 18

= (4 + 9 + 25 + 33 + 22 + 23 + 93) / 18

= 209 / 18

= 11.61 (rounded to two decimal places)

Therefore, the mean of the data represented by the stem and leaf plot is approximately 11.61.

To find the median of the data represented by the stem and leaf plot, we need to first determine the actual values represented by the plot.

the length of side AB of triangle ABC is 6 units.

How to find the length?

To find the length of side AB of triangle ABC, we can use the distance formula which is given by:

distance = sqrt((x2 - x1)² + (y2 - y1)²)

Where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the line segment.

Using the distance formula, we can calculate the length of side AB as follows:

AB = sqrt((2 - (-4))²+ (3 - 3)²)

AB = sqrt((6)²+ (0)²)

AB = sqrt(36)

AB = 6

Therefore, the length of side AB of triangle ABC is 6 units.

We can also visualize the triangle on the graph and see that side AB is a horizontal line segment between the points (-4,3) and (2,3), which have the same y-coordinate. This makes the length of AB equal to the horizontal distance between these two points, which is simply 2 - (-4) = 6.

It is important to note that the distance formula can be applied to find the length of any line segment in the coordinate plane, as long as we know the coordinates of its endpoints.

We then used algebra to rearrange the inequality and solve for x, which gave us the maximum amount of water that the family can use without going over budget.

Here we have

The cost of the water bill is made up of two components: a fixed monthly connection fee of $2, and a variable cost based on the amount of water used.

The variable cost is $5 per thousand gallons, and the total cost, C, in dollars can be expressed as:

Interest is the cost incurred when lending and borrowing a specific amount of money from a financial standpoint. It is crucial to note that interest is calculated as a percentage.

given,

Statement I is correct because the inflation rate averaged 1.3%, and Maria's savings account earned interest at a rate of 0.725%, which is lower than the inflation rate. This means that the buying power of her gift decreased by approximately 1.3% - 0.725% = 0.575% or 0.6% (rounded).

Statement II is also correct because Maria's savings account earned interest on the deposit of $2,000 for one year at a rate of 0.725%. The interest earned can be calculated as:

Interest = Principal x Rate x Time

Interest = $2,000 x 0.00725 x 1 year

Interest = $14.50

However, statement III is not correct. Since Maria deposited the entire gift of $2,000 into the savings account and did not make any withdrawals during the year, the balance in the account at the end of 2016 would be the sum of the initial deposit and the interest earned, which is $2,000 + $14.50 = $2,014.50.

There are 5 possible outcomes and 2 evens on the spinner, so 2 favorable outcomes. That gives us a fraction of 2/5.

Flipping a coin, either heads or tails, it'd be 1/2.

Since it's a compound event we would multiply 2/5 and 1/2, getting:

[tex]\frac{2}{5} *\frac{1}{2} = \frac{2}{10}[/tex]

To change that into a percentage, we divide the numerator by the denominator and multiply by 100 which would give us:

To construct a confidence interval for the proportion of American adults who viewed China as either "unfriendly" or "an enemy," we can use the following formula:

CI = p ± z*(√(p(1-p)/n))

where:

CI is the confidence interval

p is the sample proportion (0.29 + 0.09 = 0.38)

z is the critical value for the desired confidence level (95% confidence level corresponds to z = 1.96)

n is the sample size (2,047)

Plugging in the values, we get:

CI = 0.38 ± 1.96*(√(0.38*(1-0.38)/2047))

CI = 0.38 ± 0.018

CI = (0.362, 0.398)

Therefore, we can say with 95% confidence that the true proportion of American adults who view China as either "unfriendly" or "an enemy" is between 0.362 and 0.398.

Answer:

The reason why -2^2=-4 and (-2)^2=4 is due to the rules of mathematical operations and the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

According to the order of operations, when you have an expression with multiple operations, you must perform the operations in a specific order. Exponents come before multiplication and division, and before addition and subtraction.

So, when evaluating -2^2, you first evaluate the exponent, which is 2. However, the negative sign in front of the 2 is not part of the exponent, but rather an arithmetic operation. Therefore, the expression is equivalent to -(2^2), which is equal to -4.

On the other hand, when evaluating (-2)^2, the parentheses indicate that the negative sign is part of the base, so you must first evaluate the base, which is -2, and then apply the exponent of 2. This gives you (-2)^2 = 4.

Step-by-step explanation:

The minus in (-2)^2 is enclosed in parentheses, so it is also squared:

minus × minus = plus

And talking about this one: -2^2, the minus is not included in the parentheses, that's why we only square the number (2 in this case) and keep the minus in front of it
