I think that if you use 2 and 3 I think you have to mutually understand the difference between 3 and 2

SOLVE. integration of (1-v) /(1+v^2)

Nutka1998 [239]

$\displaystyle\int\frac{1-v}{1+v^2}\,\mathrm dv=\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv$

The first integral is already standard and has an antiderivative in terms of $\arctan v$ . For the second integral, take $w=1+v^2$ so that $\dfrac{\mathrm dw}2=v\,\mathrm dv$ . Then

$\displaystyle\int\frac{\mathrm dv}{1+v^2}-\int\frac v{1+v^2}\,\mathrm dv=\arctan v-\frac12\int\frac{\mathrm dw}w$
$=\arctan v-\dfrac12\ln|w|+C$
$=\arctan v-\dfrac12\ln(1+v^2)+C$

Which of the following describes the transformation of g(x)=-(2)^x+4from the parent function f(x)=2^x

Marina CMI [18]

Answer:

Shift 4 units left, reflected over x-axis, shift two units down.

Step-by-step explanation:

ok, so what happened was 4 was added to every x, the whole thing was multiplied by -1 and -2 was added to the whole function

adding 4 to every x shifts the graph to the left 4 units

multiplying the whole function by -1 reflects it over the x axis

adding -2 to the whole function moves it down2 units

plz mark me as brainliest :)

A circle has a circumference of. 153..86 units . What is the radius of the circle ???

Akimi4 [234]

Step-by-step explanation:

Circumference = 153.86 units

Radius (r) = ?

We know

circumference = 2πr

153.86 = 2 * 3.14 *r

6.28r = 153.86

r = 153.86/6.28

r = 24.5 units

Hope it will help you :)
