Answer:

Question D.

Pretty simple if you know what the distributive property is. In this equation, you notice 2 fractions outside the parenthesis. This means you must multiply this fraction by every number within its corresponding parenthesis. So, if you distribute the new equation would be \((\frac{5}{4}y+ 1)=(\frac{2}{3}y-\frac{1}{3})\). After this isolate the variable y and solve. I'll leave that to you so you can get something out of it, because my entire explanation would be useless if you just looked at the answer and left, not knowing how to do it in the future. :)

The answer is 54.5 on edg

For the triangle shown on the right, the term cos is used to complete the statement and the value of x is 54.5 degree for the triangle.

In a right angle triangle ratio of adjacent side to the hypotenuse side is equal the cosine angle between them.

\(\rm \cos=\dfrac{ adjacent}{hypotenuse}\)

Here, (a) is the adjacent side, (c) is the hypotenuse side and θ is the angle made between them.

The traingle is not provided in the image. Let the triangle for the given problem is similar to the attached image below.

Here the hypontenuse side is AC and adjacent side of triangle is 14.1 units. Thus by the property of right angle triangle,

\(\cos75=\dfrac{AB}{AC}\\\cos75=\dfrac{14.1}{x}\)

Now if we compare the above equation with the given statement __(75*)=14.1/x. The term cos is filled in the blank.

For the second part, we need to find the value of x. Thus solve the above equation further as,

\(\cos75=\dfrac{14.1}{x}\\x=\dfrac{14.1}{\cos75}\\x=\dfrac{14.1}{0.25882}\\x\approx54.5^o\)

Hence, For the triangle shown on the right, the term cos is used to complete the statement and the value of x is 54.5 degree for the triangle.

The equilibrium point for James T-shirt business is (P, Q) = (7, 24).

To find the equilibrium point (P, Q) for James T-shirt business

we need to set the demand function equal to the supply function and solve for the values of P and Q.

Demand function: P = -Q + 31

Supply function: P = Q - 17

Setting them equal:

-Q + 31 = Q - 17

Adding Q to both sides and subtracting 31 from both sides:

2Q = 48

Dividing both sides by 2:

Q = 24

Now, we can substitute this value of Q into either the demand or supply function to find the corresponding value of P.

P = Q - 17

P = 24 - 17

P = 7

Therefore, the equilibrium point for James T-shirt business is (P, Q) = (7, 24).

The approximate surface area of the package is approximately 245.05 square inches.

The best model for the package is a cylinder.

To calculate the approximate surface area of the package, we need to find the lateral surface area of the cylinder and the area of the circular base.

The lateral surface area of a cylinder can be calculated using the formula:

Lateral Surface Area = 2πrh

where r is the radius of the base and h is the height.

The area of the circular base can be calculated using the formula:

Area of Base = \(πr^2\)

Given that the diameter of the bottom is 9 inches, the radius (r) would be half of that, which is 4.5 inches.

Using the given height of 13 inches, we can now calculate the surface area:

Lateral Surface Area = 2πrh = 2π(4.5)(13) ≈ 117.81 square inches

Area of Base = \(πr^2 = π(4.5)^2 ≈ 63.62\) square inches

To find the total surface area, we add the lateral surface area and the area of the base:

Total Surface Area = Lateral Surface Area + 2 × Area of Base = 117.81 + (2 × 63.62) ≈ 245.05 square inches

Therefore, the approximate surface area of the package is approximately 245.05 square inches.

Answer:

D

Step-by-step explanation:

the y-intercept is nothing else than the y-value when x = 0 (the point where the graph intersects the y-axis, which is the vertical line at x=0).

for x = 0 we need to use the middle definition

f(x) = -x + 1

because -2 <= x < 3, and that is the interval, where we find 0 (larger than -2 and smaller than 3).

so,

f(0) = -0 + 1 = 1

so, D is the correct answer

No; the coefficient shows that as a percentage of the mean, the quarter-milers' times show more variability.

To summarize the variability in the data, we can calculate the standard deviation and the coefficient of variation for both the quarter-mile and mile runners.

Standard deviation:

Quarter-mile times:

mean = (0.92 + 0.96 + 1.04 + 0.93 + 1.00) / 5 = 0.97

differences from mean = [0.92 - 0.97, 0.96 - 0.97, 1.04 - 0.97, 0.93 - 0.97, 1.00 - 0.97] = [-0.05, -0.01, 0.07, -0.04, 0.03]

squared differences = [0.0025, 0.0001, 0.0049, 0.0016, 0.0009]

sum of squared differences = 0.01

standard deviation = √(sum of squared differences / (number of data points - 1)) = sqrt(0.01 / 4) = 0.049

Mile times:

mean = (4.52 + 4.35 + 4.60 + 4.71 + 4.51) / 5 = 4.56

differences from mean = [4.52 - 4.56, 4.35 - 4.56, 4.60 - 4.56, 4.71 - 4.56, 4.51 - 4.56] = [-0.04, -0.21, 0.04, 0.15, -0.05]

squared differences = [0.0016, 0.0441, 0.0016, 0.0225, 0.0025]

sum of squared differences = 0.0727

standard deviation = √(sum of squared differences / (number of data points - 1)) = sqrt(0.0727 / 4) = 0.139

Coefficient of variation:

Quarter-mile times: coefficient of variation = standard deviation / mean = 0.049 / 0.97 = 0.051 (to 2 decimal places)

Mile times: coefficient of variation = standard deviation / mean = 0.139 / 4.56 = 0.0305 (to 4 decimal places)

The use of the coefficient of variation indicates that the coach's statement should be qualified. The coefficient shows that as a percentage of the mean, the mile runners' times have less variability (3.05%) compared to the quarter-mile runners' times (5.1%). So, the answer is (ii) no; the coefficient shows that as a percentage of the mean, the quarter-milers' times show more variability.

The function f(x) = -4(x+2)² - 12 can be rewritten in the form

f(x) = -4x² - 16x - 28.

The concept used in this problem is expanding and simplifying an algebraic expression. We are given a quadratic function in a different form, and we need to rewrite it in standard form, which is in the form of f(x) = ax² + bx + c.

This involves expanding and simplifying the squared term and combining like terms. The process of expanding and simplifying an algebraic expression is a fundamental concept in algebra.

Here we have

f(x)= -4(x+2)²- 12      

To rewrite the function f(x) = -4(x+2)² - 12 in form f(x) = ax² + bx + c

Expand the squared term and simplify the expression.

The steps are as follows:

f(x) = -4(x+2)² - 12 (original function)

f(x) = -4(x² + 4x + 4) - 12 (expand the squared term)

f(x) = -4x² - 16x - 16 - 12 (distribute the -4)

f(x) = -4x² - 16x - 28 (combine like terms)

Therefore,

The function f(x) = -4(x+2)² - 12 can be rewritten in the form

f(x) = -4x² - 16x - 28.

What is a linear function?

A linear function is a mathematical function that has a constant rate of change, or slope, between its input and output variables. In other words, the output of a linear function changes at a constant rate as the input changes.

The given function y = x(x + 3) is not a linear function because it contains a squared term (x^2) and thus has a non-constant rate of change.

To complete the table for the given function, we substitute each input value into the equation and simplify:

Step-by-step explanation:

The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find the product of m(x) and n(x), we need to multiply the two polynomials term by term:

m(x) = x² + 3

n(x) = 5x + 9

mn(x) = (x² + 3) (5x + 9)

Multiplying the two polynomials using the distributive property.

mn(x) = 5x³ + 9x² + 15x + 27

Step-by-step explanation:

Like terms are the terms that share the same variables. They do not have to share the same coefficients - or, in other words - the numbers in front of the variable do not have to be the same. Only the variable has to match.

So, looking at the expression, the only two terms that have the same variable are 8x and 3x, which both have the variable x. Therefore, 3x and 8x are like terms.
