(a) The integral is equal to the area of the triangle; it has height 20 and base 10, so the area is 20*10/2 = 100.
(b) The integral is equal to the area of the semicircle with radius 10. It's also under the horizontal axis, so the area is negative. The semicircle has area
, so the integral is -50π.
(c) First compute

which is the area of the triangle on the right. It has height and base 5, so its area is 25/2.
Then split up the desired integral as

and plug in the integral values you know:

Answer:
Point S coordinates= (-4,5)
Step-by-step explanation:
If you would just move the point 5 PLACES TO THE RIGHT, you would get -4, 5, which is the correct answer.
Answer:
I'm pretty sure it's the last one.
Step-by-step explanation:
Answer:
48
Step-by-step explanation:Its because they stated that f(1)= 8 so something times one = 8 which would of course be 8 so now u know that f=8 then u do 8(6) which is 48
2,600/4 =650
650•5 =3,250
I found the unit rate of the 2,600 by dividing the per hour and then times it by the 5 hours
