Answer:
$47,520
Step-by-step explanation:
A.
the area of a polygon is/
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=
$47,520
Answer:
B. 7.3 %
Step-by-step explanation:
Given:
Initial average grade = 82
Final average grade = 88
Duration for the increase = 3 weeks
Therefore, increase in average grade = Final - Initial = 88 - 82 = 6
Now, percent increase in average grade is given as:

Therefore, the percent increase in her average grade over the 3-week period is 7.3 %.
The option that describes h(x) is B. The function h(x) is increasing on the interval (5, ∞).
<h3>What is a function?</h3>
In mathematics, a function simply means a relation between the inputs and the outputs.
In this case, the information given is that h(x) is 2 times the square root x minus 5. The square root of the negative number cannot be taken, therefore, the domain of the function is restricted.
Since the domain is restricted, the function is increasing. Therefore, the function h(x) is increasing on the interval (5, ∞).
