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:
The answer is 173,595
Step-by-step explanation:
Firstly, you multiply 815 by the first number of 213 which is 3
So:
Then 815 by the second number:
Then 815 by the third number:
Then you add all the numbers, but you have to put a zero to the right of the second product and two zeroes to the third product and so on..
In this case the addition is :
2445+8150+163000 = 173595
