Find f'(x) for f(x)=cos^2(5x^3).
-BARSIC- [3]

d/dx cos^2(5x^3)

= d/dx [cos(5x^3)]^2

= 2[cos(5x^3)]

= - 2[cos(5x^3)] * sin(5x^3)

= - 2[cos(5x^3)] * sin(5x^3) * 15x^2

= - 30[cos(5x^3)] * sin(5x^3) * x^2

Explanation:

d/dx x^n = nx^(n - 1)

d/dx cos x = - sin x

Chain rule:

d/dx f(g(...w(x))) = f’(g(...w(x))) * g’(...w(x)) * ... * w’(x)

In Rodger's state, unemployment compensation is calculated by finding the total of the quarterly wages of two consecutive quarte
frozen [14]

Rodger's weekly unemployment amount is $ 705.0225

Given,

The total of the quarterly wages of two consecutive quarters and dividing by 26.

The weekly unemployment is 65% of that amount.

Rodger made a total of $13,950.80.

and, he made a total of $14,250.10

We have to follow the some steps for solving question:

Step 1:  Find the total of the quarterly wages of two consecutive quarters.

= $ 13,950.80 + $ 14,250.10

= $28,200.90

Step 2 : Divide the total  by 26

  = $28,200.90 / 26

  =  1,084.65

Step 3 : Find the 65%

  =   1,084.65 x 65%

  =  1,084.65 x 65/100

  =   705.0225

Hence, Rodger's weekly unemployment amount is $ 705.0225

An inspector at a factory examines 320 drinking glasses, and 12 of them have defects. The inspector then examines 560 drinking g
fgiga [73]

Answer: 539 without defects

Step-by-step explanation: Im pretty sure we have to turn 12/320 into a percent, which is 0.0375, or 3.75%

So with that information, we need to find 3.75% of 560.

do 0.0375 x 560, which is 21.

21 are defects, so do 560 - 21 is 539.
