Answer:

If z =1/2, which expression has the greatest value?

1. (z^-2 z^5)^-2 = (z^3)^-2 = 1/z^6 = 1/(1/2)^6 = 2^6 = 64

2. (z^3)^5 = z^15 = (1/2)^15 = 1/(2^15)

3. z^-6 z^4 = z^-2 = (1/2)^-2 = 1/2^2 = 1/4

4.-(z^2 z^-4)^-3 is negative 64

You need to design a rectangle with a perimeter of 14.2 cm. The length must be 2.4 cm. What is the width of the

irina1246 [14]

Part (a)

<h3>Answer: 2(2.4+w) = 14.2</h3>

--------------

Explanation:

L = 2.4 = length

W = unknown width

The perimeter of any rectangle is P = 2(L+W)

We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2

========================================================

Part (b)

<h3>Answer: w = 4.7</h3>

--------------

Explanation:

We'll solve the equation we set up in part (a)

2(2.4+w) = 14.2

2(2.4)+2(w) = 14.2

4.8+2w = 14.2

2w = 14.2-4.8

2w = 9.4

w = 9.4/2

w = 4.7

The width must be 4.7 cm.
