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
C=15+3. Combine like terms. C=18.
Answer:
$729.00
Step-by-step explanation:
The tax is ...
0.08 × $675 = $54.00
So, the total cost of the bike is ...
$675 +54 = $729.00
Okay, you ordered $23.91 worth of food and $9.27 worth of drinks. Add them and you get $33.18. Since the sales tax rate is 6%, this means that it is $1.99. Adding the tax to your meal would leave a total cost of $35.18. Have a great day!
