I'm going to rewrite f(t) to make it a little easier to use the power rule:

Now just take the derivative using the power rule:

Since they ask for f'(a), we need to replace the t's with a's:
Answer:d=-1
Step-by-step explanation: you subtract 8 from both sides to get -4d=4 then divide -4 to get d alone. Which will get you to -1=d
Step-by-step explanation:
Surface area= p×h+ 2 area of triangle
side=4.97
p=3×4.97=14.92
area=10.75
total surface area=321.5
The number of chicken wings that Mohal can buy is 12.
<h3>How to calculate the cost?</h3>
It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:
= Total amount / Number of chicken wings
= $50 / 20
= $2.50
When he spent $30.00, the number of wings will be:
= Amount / Cost per wing
= $30 / $2.50
= 12
There will be 12 chicken wings. This illustrates the proportion.
