Answer:
B) 864 feet
Step-by-step explanation:
Here's my answer. I'm not too sure how to form the equation though. Hope this helps :)
What do you need help with?
The answer is 17 1/4...but you probably can’t have 1/4 of a pie, so Mat can make a total of 17 pies
Let r(cos O + i sin O) be a cube root of 125(cos 288 + i sin 288)
then
r^3(cos O + i sin O)^3 = 125(cos 288 + i sin 28)
so r^3 = 125 and cos 3O + i sin 3O = cos 288 + i sin 288
so r = 5 and 3O = 288 + 360p and O = 96 + 120p
so one cube root is 5 (cos 96 + i sin 96)
Im a little rusty at this stuff Its been a long time.
Im not sure of the other 2 roots
sorry cant help you any more
