diameter (d) = 2 · r

Circumference (C) = 2 π · r → C = π · d → d = $\frac{C}{\pi}$

Explain in detail with at least two sentences how to represent the product of A and B geometrically given that A=15+56i and B =

Nookie1986 [14]

Basically each part of the first complex number gets multiplied by each part of the second complex number. You are multiplying 2 binomials.

(15 + 56i(7 + 4i)

= 105 + 60i + 392i + 224i^2

= 105 + 452i - 224 ( because i^2 = -1)

= - 119 + 452i

A survey of 2,000 doctors showed that an average of 3 out of 5 doctors use brand X aspirin. How many doctors use brand X aspirin

This is a proportion problem that involves cross-multiplication
Set your problem up like so:
$\frac{x}{2,000}$ = $\frac{3}{5}$

Now cross multiply
2,000 x 3 = 6,000
now you're left with 5x = 6,000
Now divide by 5 on both sides
Answer is 1,200
