HELP WITH CALC!!

Answer 1

2\[2\int\limits_{?}^{5} 10x- 10/x{2} dx\]

Answer 2

You mean \(\displaystyle \int_2^5 \dfrac{10x - 10}{x^2}dx\) ?

Answer 3

yes

Answer 4

can you help?

Answer 5

i can help if greeky is busy

Answer 6

i dont cARE YOU HELPS HAHA

Answer 7

ok this is simple, but i care i don't like to take someone's else work

Answer 8

if mr 42 give me permission i will proceed

Answer 9

just one small hint for the sake of simplification divide by x^2

Answer 10

ok

Answer 11

split the denominator between the two terms

Answer 12

both can be reduced to standard integrals

Answer 13

no i am just in geometry right now but if i get this right i will get 30% of a shirt it is some local thing can you guys please help !!!!

Answer 14

\[\displaystyle \int\limits\limits_2^5 \dfrac{10x - 10}{x^2}dx =10 \int\limits\limits_{2}^{5} \frac{dx}{x}-10\int\limits\limits_{2}^{5}\frac{dx}{x^2}\]

Answer 15

so what would be the final answer?

Answer 16

ok i will show u the answer

Answer 17

thank you so much!!!!!!!

Answer 18

\[= \frac{10}{x}+10\ln(x) \left(\begin{matrix}2 \\ 5\end{matrix}\right)\]

Answer 19

so all u need to do is plug in 2 and takeaway from 5

Answer 20

so the answer is 25?

Answer 21

its like -19 right?

Answer 27

thats what i got when i pluged in the prob

Answer 28

\[= \frac{10}{5}+10\ln(5) -\frac{10}{2}-10\ln(2) \]

Answer 29

\[=(2-5) -10\ln(2)+10\ln(5)\]

Answer 30

\[=-3 -10\ln(2)+10\ln(5)\]

Answer 31

you can keep the answer this way, there is no harm

Answer 32
