An FM radio station signal travels in a 40-mile radius. An AM radio station

MrMuchimi

Answer:

4976.28 square miles (nearest hundredth)

Step-by-step explanation:

$\textsf{Area of a circle}=\pi r^2 \quad \textsf{(where r is the radius)}$

FM radio station

Given:

r = 40 miles

$\implies \textsf{Area}=\pi (40)^2=1600 \pi \: \sf miles^2$

AM radio station

Given:

r = 4 miles

$\implies \textsf{Area}=\pi (4)^2=16 \pi \: \sf miles^2$

Difference:

$\begin{aligned}\implies \textsf{FM area - AM area} & =1600 \pi - 16 \pi\\ &= 1584 \pi\\ & =4976.23\:\textsf{square miles (nearest hundredth)}\end{aligned}$

X^2 + 10x + 29 = 0 How do I solve this equation (imaginary numbers acceptable)

Leona [35]

X^2+10x+29=0

Quadratic Formula:
−b±√b^2−4(ac)/2a

Substitute the values :
a=1, b=−10, and c=29

into the quadratic formula and solve for
x.

10±√(−10)^2−4•(1•29)/ 2•1

Simplify.

Answer: x=5±2i
