Remark

You need 2 facts to solve this 

1.   The area of a hexagon is 

     A = 3*(sqrt(3) ) * a^2/2 

     Just to make this clear, I'll put it in Latex

Area = (3*\sqrt3 a^2)/ 2

2. The second fact you need to know is that the radius = the length of the side a.

Givens

r = 20 in

a = r where a is the length of the side of a hexagon.

Formula Substitute and solve.

A = 3*(sqrt(3) * a^2 ) / 2

A = 3*(sqrt(3) * 20^2) / 2

A = 3*sqrt(3) * 400 / 2

A = 3*sqrt(3) * 200

A = 3*1.7321 * 200

A = 1039 square inches.

A tire company finds that the lifespan for one brand of its tires is normally distributed with a mean of 47,500 miles and a stan
Illusion [34]

Answer:

42580 miles

Step-by-step explanation:

Mean = \mu = 47500

\sigma = 3000

The manufacturer does not want to replace more than 5% of the tires

P(X\leq x)=5\%

P(\frac{x-\mu}{\sigma}\leq \frac{x-47500}{3000})=0.05

By using normal table values :

\frac{x-47500}{3000}=-1.64

x=(-1.64 \times 3000)+47500

x=42580

Hence the approximate number of miles for the warranty is 42580 miles

Which statement best describes f(x) = -2 times the square root of x-7+1
BigorU [14]

Answer:

f(x) = -2*sqrt(x - 7 + 1)

Step-by-step explanation:

If by "statement" you mean equation, then it's pretty self-explanatory. Sorry if I'm confused though, you probably didn't list the proper choices.
