Find f'(x) if f(x) = (2/(x^1/3)) + 3 cos x + x^pi

galben [10]

The derivative of $f$ is

$f'(x)=\left(2x^{-1/3}+3\cos x+x^\pi\right)'$

$f'(x)=\left(2x^{-1/3}\right)'+(3\cos x)'+\left(x^\pi\right)'$

By the power rule,

$f'(x)=-\dfrac23x^{-4/3}+(3\cos x)'+\pi x^{\pi-1}$

The derivative of $\cos x$ is $-\sin x$ :

$f'(x)=-\dfrac23x^{-4/3}-3\sin x+\pi x^{\pi-1}$

What is the slope of the line passing through the points (-5,7) and (-3,5)

lbvjy [14]

Answer:

Slope of the line passing through the points (-5,7) and (-3,5) is -1.

Step-by-step explanation:

slope of line passing through point (x1,y1) and (x2,y2) is given by

m = (x2-x1)/(y2-y1)

____________________________________________

In the problem given points are (-5,7) and (-3,5)

using the formula for finding slop ewe have

m = (-3-(-5))/(5-7)

=> m = (-3+5)/-2

=> m = 2/-2

=> m = -1

Thus, slope of the line passing through the points (-5,7) and (-3,5) is -1.

Select the correct answer. During the summer, Jody earns $10 per hour babysitting and $15 per hour doing yardwork. This week she

omeli [17]

Answer:

A. x + y = 34; 10x + 15y = 410

Step-by-step explanation:

Jody's total hours will be the sum of the hours spent on each job:

x + y = 34 . . . . . total hours

Jody's total earnings will be the sum of the earnings from each job:

10x +15y = 410 . . . total earnings

So, the system of equations is ...

x + y = 34
10x + 15y = 410
