Answer:
C(h)= 5(h-1) + 12
Step-by-step explanation:
the cost of renting a kayak is $12 for the first hour plus another $5 for each additional hour.
Initial cost , that is cost for 1 hours is $12
LEt h be the number of hours renting a kayak
for 1 hours is $12 and for remaining (h-1) hours the cost of renting is $5 per hour
Total cost = 5 (remaining hours) + cost of first hour
75π in²
The shaded sector is 3/4 of the circle. We can use the area formula for a circle to find the area of the whole circle, then multiply that result by 3/4.
A = πr² = π(10 in)² = 100π in²
Then the area of 3/4 of the circle is ...
3/4·A = (3/4)·100π in² = 75π in²
32
80/2 = 40
64/2 = 32
so she can make about 32
