Question

Can someone please check my answer that I got.....

Answer 1

I dont know

Answer 2

what did you get for an answer ?

remember that you can split the sum into 2 integrals and then add the results of the 2 integrals.

Answer 3

@e.mccormick can you check my answer that I got please

Answer 4

I got 5

Answer 5

@phi I got 5 for an answer is that correct

Answer 6

you can split integral (a +b) into integral a + integral b
they tell you what the integral a is
ditto for integral b
what are they ?

Answer 7

b=9 a=4

Answer 8

if you add them together then the answer is 13

Answer 9

those are the limits. Don't get confused with the changing definitions

I meant what is
\[ \int_4^9 a(x) dx \] ?
they tell you.
same question for the integral of b(x)

Answer 10

I am confussed on what you are asking

Answer 11

Do you see they write
\[ \int_4^9 a(x) dx = ??? \]
what is the number they write ?

Answer 12

oh wait I understand now a=11 and b=17

Answer 13

yes, what they are trying to teach is that if you see
\[ \int_4^9 (a(x) + b(x) ) dx \]
that you can break that into 2 integrals
\[ \int_4^9 a(x) dx + \int_4^9 b(x) dx\]

now you can use 11 and 17 for the results of the integrals.
add them up

Answer 14

so then the final answer is 28

Answer 15

just checking 28 is correct yes

Answer 16

Yes.

Answer 17

medal = yes correct

Answer 18
