Answer:
The length of the arc is 4.6375 miles
Step-by-step explanation:
Firstly, find the perimeter of the circle by doing 2*pi*r, you'll get about 18.55 miles.
2*pi*r ---> 2*pi*3 ---> 6*pi ---> ≈ 18.55 miles
Next, plug in x/360, where 360 is the total arc of a circle, and x is the arc you need.
x/360 ---> 90/360 ---> = 0.25
Lastly multiply the two numbers.
18.55 * 0.25 ---> 4.6375 miles is your answer.

Answer:
Step-by-step explanation:
we would like to find the inverse of the following function:
to do so substitute y for f(x):
interchange variables:
cancel 9 from both sides:
square both sides:
add 4 in both sides:
divide both sides by 4:
substitute back:
and we're done!
Answer:
Step-by-step explanation:
Start by changing the dollars into cents.
2.07 dollars = 2.07 * 100 = 207 cents
1.64 dollars = 1.64 * 100 = 164 cents.
How much does 1 ounce cost for each?
207 cents / 48 = 4.3125 cents / oz
164 / 32 = 5.125
The better buy is the 48 fluid oz jar.
Answer is D cause the equation of the line is y=3x
