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
Answer:
81/16 = 5 1/16
Step-by-step explanation:
-4(square root of x) -3 = -12
Add 3 to both sides
-4(square root of x) = -12 +3 = -9
Divide both sides by -4
(square root of x) = -9/-4
-/- equals +
(square root of x) = 9/4
Square both sides to cancel the square root
x = (9/4)^2 = 81/16 = 5 1/16
