David is writing an explicit function for the arithmetic sequence: 10,13,16,19...

He comes up with s(n)=7+3n

What domain should David use for s so it generates the sequence?

A. n ≥ 0, where n is an integer

B. n ≥ 0 , where n is any number

C. n ≥ 1 , where n is an integer

D. n ≥ 1 , where n is any number

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
