Question

Part 1 -Sample roller coasters warm up:

Answer 1

Answer:

Step-by-step explanation:

h(t) = 0.3t -t +21t , t=time and h=height

1.

at t=0  the hight is h=0

h(0) = 0.3*0 -0 +21*0 = 0

It makes sense that at the time 0 seconds when the rollercoaster did not leave the hight is 0 feet.

2.

for t=10 substitute t with 10

h(10) = 0.3*10 -10 +21*10 = 3 -10 +210 = 203

3. see graph

4. the rollercoaster is going up
