julsineya [31]
We know that
circumference of a circle=2*pi*r
for r=200 miles
circumference of a circle=2*pi*200-----> 1256 miles

if 360° (full circle) has a length of------------------> 1256 miles
 X°----------------> 1000 miles
x=1000*360/1256------> x=286.62°

the answer is
286.62 degrees

If u is inversely proportional to the square of v and u is 4/9 when v is 3, find u when v is 8
LenKa [72]

Answer:u=1/16

Step-by-step explanation:

u is inversely proportional to v^2

u=k× 1/v^2

u=k/v^2

When U=4/9 when v=3

4/9=k×1/3^2

4/9=k×1/9

4/9=k/9

Cross multiply

4×9=k×9

36=9k

Divide both sides by 9

36/9=9k/9

4=k

When v= 8, u=?

u=k/v^2

Recall k=4

u=4/8^2

u=4/64

u=1/16

Rapid Rental Car Company charges a $55 rental fee and $0.25 per mile driven. For the same car, Capital Cars charges $45 for rent
AlladinOne [14]

Answer:

100 miles

Step-by-step explanation:

Let the number of miles driven = x

Rapid Rental Car Company charges a $55 rental fee and $0.25 per mile driven.

$55 + $0.25x

55 + 0.25x

For the same car, Capital Cars charges $45 for rental fee and $0.35 per mile.

$45 + $0.35x

45 + 0.35x

Equation :

55 + 0.25x = 45 + 0.35x

The number of miles for which the companies’ charges will be the same is calculated as:

55 + 0.25x = 45 + 0.35x

Collect like terms

55 - 45 = 0.35x - 0.25x

10 = 0.10x

x = 10/0.10

x = 100 miles

The number of miles for which the companies’ charges will be the same is

100 miles.

Given f(x) = x − 7 and g(x) = x2 . Find g(f(−1)).
ivann1987 [24]

Answer:

64

Step-by-step explanation:

g(f(-1)) can be found by first finding f(-1) then taking that result and putting it into the function g.

f(-1) means we are going to take the expression x-7 and evaluate it for x=-1:  

-1-7

-8

So f(-1)=-8.

So we have this so far:

g(f(-1))=g(-8)=(-8)^2=64.

g(-8) was found by replacing x in x^2 with -8.
