11z/16+7z/8=5/16 how do you get the z alone?

11z ➗ 16 ➕ 7z ➗ 8 = 5 ➗ 16
x 8 x 8
11z ➗ 16 ➕ 7z = 5 ➗ 16 x 8
x 16 x 16
11z ➕ 7z = 5 x 8
18z = 40
➗ 18. ➗ 18
z=40 ➗ 18
z = 2.2

This is the way I was taught to do it. if the answer is incorrect, at least you can use my work as an example to go off of.

(what you do to one side you do to the other. I'm using my phone and everything condensed, I apologize)

The blades of a windmill turn on an axis that is 35 feet above the ground. The blades are 10 feet long and complete two rotation
Alona [7]

Answer:

h = 10sin(π15t)+35

Step-by-step explanation:

The height of the blade as a function f time can be written in the following way:

h = Asin(xt) + B, where:

B represets the initial height of the blade above the ground.

A represents the amplitud of length of the blade.

x represents the period.

The initial height is 35 ft, therefore, B = 35ft.

The amplotud of lenth of the blade is 10ft, therefore A = 10.

The period is two rotations every minute, therefore the period should be 60/4 = 15. Then x = 15π

Finally the equation that can be used to model h is:

h = 10sin(π15t)+35

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?
Llana [10]
F(x) = -x² + 4
g(x) = 6x

(g - f)(3) = 6(3) - (-(3)² + 4)
(g - f)(3) = 18 - (-9 + 4)
(g - f)(3) = 18 - (-5)
(g - f)(3) = 18 + 5
(g - f)(3) = 23
