Step-by-step explanation:
Answer:
width = 10 inches
Step-by-step explanation:
V = lwh
w = 
= 
= 
= 10 inches
Step 1-F.O.I.L.: (-2-2i)(-4-3i)
8+6i+8i+3i^2
We know i^2=-1, so...
8+14i-3
5+14i
Step 2-F.O.I.L. again: (5+14i)(7+8i)
35+40i+98i+112i^2
35+138i-112
-77+138i
Note: "F.O.I.L." stands for "First, Outer, Inner, Last". In other words, distribute the terms of the first binomial to the other, in that order. So, (5+14i)(7+8i) should be done as follows:
5*7=56
5*8i=40i
14i*7=98i
14i*8i=112i^2
Using the formula for circumference from diameter (c=pi(d)), we find that the circumference of the ferris wheel is about 197.97 feet. We then multiply that number by the revolutions to get 2,374.64 feet, which is the answer.
