Question

NEED HELP WILL GIVE MEDAL!!!

Answer 1

if \[\int\limits_{0}^{a}(4-2x).dx =4 \] find a

Answer 2

the integral is 4x - x^2 from 0 to a.

do you know how to plug in the limits?

Answer 3

I think so don't u just substitute?

Answer 4

yes. if the integrand is f'(x) and the integral which we found is f(x). to plug in the limits from a to b you do f(b) - f(a)

Answer 5

= 4(a) - (a)^2 - 4(0) - (0)^2 = 4

Answer 6

solve for a :)

Answer 7

4a - a^2 = 4
a-a^2 = 1
= -a(1-a)
X = o or -1

Answer 8

a^2 - 4a + 4 = 0

Answer 9

(a-2)^2 = 0

sorry for delay of replying. was doing own homework and forgot
