experts, geniuses, aces and moderators .. need help on the attached. will give brainliest!!! find the derivative of e^x
STatiana [176]
To find the derivative, you must use the chain rule.

If u=x^3+2x:
dy/dx=(dy/du)(du/dx)
dy/du=d/du(e^u)=e^u=e^(x^3 + 2x)
du/dx =d/dx (x^3+2x) = 3x^2 + 2

So dy/dx=
e^(x^3+2x) * (3x^2+ 2)

ziro4ka [17]

Answer: The sample should contain 4870 cans of paint.

Step-by-step explanation:

According to the given information , we have

The prior estimate of proportion= p=0.10

Margin of error : E=0.01

Critical value for 98% confidence interval =z_{\alpha/2}=2.326

Formula to find the sample size :

n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2

i.e. n=0.10(1-0.10)(\dfrac{2.326}{0.01})^2

=4869.2484\approx4870

Hence, the sample should contain 4870 cans of paint.
