You can helps me? <br>f(x) = x + 20 <br>g(x) = x + 5 <br>(f o g) (2) = ?

pav-90 [236]

<h2>♪Answer : </h2>

f(x) = x + 20
g(x) = x + 5

»(f o g)(2)

find (f o g)(x)

»f(g(x))

»f(x + 5)

»x + 5 + 20

»x + 25

so, (f o g)(2) is

»2 + 25

Answer 7x9-8+11-6[5+2(-3)]

Anna [14]

I got 0.

First you look at the parenthesis, 2•-3 which = -6.
Second, distribute -6 (the one before the [5+2(-3)]).
It will look like 7x9-8+11-30-33

Evaluate the line integral, where C is the given curve. (x + 4y) dx + x2 dy, C C consists of line segments from (0, 0) to (4, 1)

zubka84 [21]

Parameterize the line segments (call them $C_1$ and $C_2$ , respectively, by

$\vec r_1(t)=(1-t)(0,0)+t(4,1)=(4t,t)$

$\vec r_2(t)=(1-t)(4,1)+t(5,0)=(4+t,1-t)$

both with $0\le t\le1$ . Then

$\displaystyle\int_C(x+4y)\,\mathrm dx+x^2\,\mathrm dy$

$=\displaystyle\int_0^1\bigg((4t+4t)(4)+(4t)^2(1)\bigg)\,\mathrm dt+\int_0^1\bigg((4+t+4(1-t))(1)+(4+t)^2(-1)\bigg)\,\mathrm dt$

$=\displaystyle\int_0^115t^2+21t-8\,\mathrm dt=\boxed{\frac{15}2}$

Please help me answer this !

Answer: 15 x (1/3)

Step-by-step explanation: 15 divided by 3 is 15 right. When you multiple 15 and 1/3 it is like taking one third out of 15. One third out of 15 is 5. Hope this helped! :P
