Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft
-sin(-x)/cos(-x)*cos(-x)/sin(-x)
Simplifying, we get 1
All the angles should add up to 360
So you know 1 is 110
But you also know 1 is 90 because of the square so you know half is equal to 200
So you are working with 160=360-200
So now you look at the number left and say what number can be doubled and still have enough left over to add 10.
So I guess 50 times 2 is 100
And 50 plus 10 is 60
So check does this add up to be 160?yes
So x is 50
Good luck

+ y × 2y.
Third, simplify exponent. / Your problem should look like:

+

× 2.
Fourth, regroup terms. / Your problem should look like:

+

, which is your answer.
Answer: here’s both
Step-by-step explanation:
1st: f(0) = 3 = a*b0 Therefore 3 = a (1)
f(1) = ab = 15
3b =15
b =5
a =3 b =5
f(-2) = 3.5-2 = 3/25
