Answer: Mr. Shahoian need to purchase 9 pieces of fencing.
Step-by-step explanation:
Given: Length of fencing around the flower beds in his backyard = 166.25 ft
The fencing is sold in lengths of 19 ft each.
Number of pieces of fencing = (Length of fencing ) ÷ (19)
i.e. Number of pieces of fencing = 166.25 ÷ 19
= 8.75 ≈ 9
Hence, Mr. Shahoian need to purchase 9 pieces of fencing.
Arcsin is the inverse function of sine, it switches the sine function (reverses it)
cosec is the reciprocal of sine
-9p - 5m = 60
-9p - 5m + 5m = 5m + 60
-9p = 5m + 60
-9 -9
p = ⁻⁵/₉m - 6²/₃
You have to add 5m on each side in order to find the value of p. then, you have to divide it by -9 in order to find the value of p.
