Answer:
see explanation
Step-by-step explanation:
Given
s(t) = 10t²
To find s(2) and s(5) substitute t = 2 and t = 5 into f(t)
(a)
s(2) = 10 × 2² = 10 × 4 = 40
s(5) = 10 × 5² = 10 × 25 = 250
(b)
s(5) - s(2) = 250 - 40 = 210
This represents the distance travelled in 3 hours
(c)
The average rate of change is measured as
= 
= 
= 70 miles per hour
So basically it's just a simple division equation (kind of):
600/3000
We can simplify this so the denominator is 100
20/100

Answer:
1.29 * 10^9.
Step-by-step explanation:
That is 1.4 * 10^9 - 1.1 * 10^8
= 14 * 10^8 - 1.1 * 10^8
= 12.9 * 10*8
= 1.29 * 10^9.
