The ordered pairs in the table below represent a linear function.

the table that has the same additive rate of change. so you subtract the last number to the one before it.  to get the rate of change but you need to the same with every number in the y values.

Step-by-step explanation:

for example if the table has 1,2,3,4 point with the y values with 2, 4, 6,8. so you will get 8-6=2 then you repeat: 6-4=2, 4-2=2. when they are the same meaning its a linear function.  

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)

answer: i guess 105 degrees?
