Answer:

all are Not Equivalent

Step-by-step explanation:

The coefficient of t³ in the target expression is -3. In order for that to be the result of simplifying any of the given expressions, they must have ( )^(t^3) in the denominator. None do, so none of the offered choices is equivalent to the given expression.

_____

The expressions simplify like this:

$\dfrac{(2^3)^{t^3}}{2^{5t}}=2^{3t^3-5t}\\\\\dfrac{8^{t^3}}{32^t}=2^{3t^3-5t}\\\\8^{t^3}\cdot32^t=2^{3t^3+5t}$

the length of a rectangle is 2 inches more then twice its width. find the widtg of the rectangle if the perimeter is ar least 10

Lelu [443]

Answer:

width = 16 inch.

Step-by-step explanation:

Given,

let the width be x

so, length = 2 in. more than twice its width = 2 + 2x

perimeter = 2l + 2b

we know,

perimeter = 100 in

so, 2l + 2b = 100

after inserting the values we got,

→ 2(2+2x) + 2(x) = 100

→ 4 + 4x + 2x = 100

→ 4 + 6x = 100

→ 6x = 100 - 4 = 96

→ x = 96/6 = 16

therefore, width is x so width of rectangle is 16 inch.

hope this answer helps you dear and may u have a great day ahead.

A man selling computer parts realizes that when he sells 16 computer parts, his earning is $1700. When he sells 56 computer part

natta225 [31]

We need to find the unit rate. To do so, divide the amount of money he makes by the number of parts sold. 1,700 / 16 = 106.25. So, if the man sells one computer part, he gets $106.25. To find the price of 30 parts, multiply 106.25 by 30. 106.25 * 30 = $3,187.50

The man will make $3,187.50 if he sells 30 parts.

3. The response variable is B. Whether or not a subject dies.

Step-by-step explanation:

1. An observational study is a type of study where the researcher would observe the effects and he would also make no attempt to change the outcome

2. The explanatory variable is also called the independent variable and in this case it is red meat consumption because it is what would be used to predict the dependent variable

3. The response variable is known as the dependent variable it is our variable of interest. It is what the researcher is trying to find out. In this case the answer is whether or not the subject dies

2. Which is an equation of the line with a slope of 2 that passes through (3,-5)?

Vadim26 [7]

Answer:

y + 5 = 2(x - 3) (Answer A)

Step-by-step explanation:

Since the slope and a point on the curve are given, use the point-slope formula for the equation of a straight line:

y - k = m(x - h)

Here, m = 2, h = 3 and k = -5, so we have:

y + 5 = 2(x - 3) (Answer A)
