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:
a. Jake told the negative value of the expression which cannot be equivalent to the original expression.
b. 10 - g
Step-by-step explanation:
a. The given expression is:
Multiplying through out by -, we get:
which was the expression given by Jake. Since, it is the negative of the original one, they cannot be equivalent.
b.
Hence, the answer.
