Rope of 30ft arranged in shape of a sector of a circle with central angle theta radians, what is the area of the sector, a, as the function of theta.

The area is about 90 or so, i'm assuming...

..Good luck, I hope for the best for you

Step-by-step explanation:

30 = r+r+rt = r(2+t)  

r = 30/(t+2)  

Arc length = 30t/(t+2)  

A = Area = (1/2)*Arc*radius  

A = (1/2)*30t/(t+2)*30/(t+2)  

A = 90t/(t+2)/(t+2) = 90t/(t+2)^2  

A(t) = 90t/(t+2)^2

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
