Answer all questions! 1. What’s the common ratio of the geometric sequence2,0.5,0.125,1/32? Write this geometric sequence as an explicit formula.
2. Vertically dilate the linear function z(x) = 4x−1by a factor of three. What’s the equation of the vertically dilated function?
3. Consider the linear functionsy(x) = 2x+ 8andg(x) =−2x+ 4. What are theiry-intercepts? Write these functions in factored form. What are theirx-intercepts?

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

its not b

step-by-step explanation:

is should be y = 5x

step-by-step explanation:

correct me if im wrong

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
