Question

I have the answer can somone please check me...

Answer 1

\(8+11\) for the first one

Answer 2

what?

Answer 3

\[\int_1^52dx+\int_1^5m(x)dx=8+11=19\]

Answer 4

so then my answer is 19

Answer 5

yes

Answer 6

ok thanks just to check with the others viewing is that the correct answer

Answer 7

you are told \(\int_1^5m(x)dx=11\) and
\[\int_1^52dx=4\times 2=8\]

Answer 8

11 for 2nd and 16 for 3rd

Answer 9

Here is a question for farmer:
what is the integral
\[2\int\limits_{1}^{5}dx\]

Answer 10

@satellite73 take his apporch

Answer 11

right I got 6 before but know satelitte73 said 19 is the answer

Answer 12

can you do
\[ 2\int\limits_{1}^{5}dx \]?

Answer 13

isn;t that 11

Answer 14

can you do
\[ \int dx \] ?

Answer 15

yes but I have never done anything like this before so I am getting confused my teacher didn't explain tthis section very well so I am confused

Answer 16

You should review your book.
\[ \int dx = x\]
the integration of dx is x
if we have a 2 out front we get
\[ 2\int dx = 2x\]

if we have limits, then the answer is
\[ 2 \int_{a}^{b} dx= 2 x |_{a}^{b} = 2a - 2 b\]

what is
\[ 2 \int_{1}^{5} dx \]?

Answer 17

**typo
\[ 2 \int_{a}^{b} dx= 2 x |_{a}^{b} = 2b - 2 a \]

Answer 18

the answer is then 8

Answer 19

yes, but do you see how to get 8 ?
you evaluate
\[ 2 \int_{1}^{5} dx= 2 x |_{1}^{5} = 2\cdot 5 - 2 \cdot 1 = 8 \]

Answer 20

yes I understand so then 8 is my final answer right

Answer 21

no, 8 is not the final answer. The question is
\[ \int_{1}^{5} (2+m(x)) \ dx \]
as satellite showed you can break that into 2 integrations
\[ \int_{1}^{5} 2 \ dx + \int_{1}^{5} m(x) \ dx \]

The first one we found is 8. The second integral they tell you .
you have to add the two numbers together for the final answer.

Answer 22

8+4=12

Answer 23

@farmergirl411 the way to compute \[\int_1^52dx\]is to think of a rectangle with base 4 and height 2, area \(4\times 2=8\)

Answer 24

How did you get 4 ? What does it say immediately under
Evaluate the integral below given that ....

Answer 25

the \(4\) because \(5-1=4\)

Answer 26

then you get \(8+11\) because your are told that
\[\int_1^5m(x)dx=11\]

Answer 27

@satellite73 I think farmer was using 4 instead of 11

Answer 28

so then the final answer is 19

Answer 29

Yes I was I was sing 4 I used the wrong number sorry

Answer 30

No need to be sorry. But you do want to figure out if you are confused by something, and see if you can "unconfuse" yourself.

Answer 31

yes that is right so then is 19 the final answer

Answer 32

was the medal meaning yes

Answer 33

I would be happier if you *knew* the correct answer is 19. If you are uncertain, that means it is not clear, or you are puzzled by something.

Answer 34

no I am not confused I am the type of person I want to check tomake sure the other perosn got it too that is why I am asking

Answer 35

you can be sure if satellite is answering a question about calculus, it is correct.

Answer 36

ok thanks good to know
