1 answer:

5 0

Thank you for posting you question here at brainly. I hope the answer will help you.

T (z) = 2/3z over z - 1/2
T(3) = 2/2.5 = 4/5 or 0.8
T(1/2) is indeterminate, he reason being that the denominator becomes zero. Division by zero gives an indeterminate result.

What is the volume in cubic inches?

Crazy boy [7]

Break down the figure into 2 separate rectangular solid and find each volume and sum it.

<u>Volume of smaller step:</u> The volume of any rectangular solid is given by,

$V=length*width*height$

So we have $V=8*4*3=96$

<u>Volume of larger step:</u> The only dimension that is different than the smaller step is of the height, which is 6. So we have,

$V=8*4*6=192$

Hence, the volume of the whole figure, in cubic inches, is

$V= 192+96=288$ . Answer choice B.

Solve using quadratic equations

olasank [31]

4x² - 9x² + 5 = 0
4x² - 4x - 5x + 5 = 0
4x(x - 1) - 5(x - 1) = 0
(4x - 5)(x - 1) = 0

Set each binomial equal to zero.

4x - 5 = 0
4x = 0 + 5
4x = 5
x = 5/4

x - 1 = 0
x = 0 + 1
x = 1

Your solutions are x = 1, 5/4
