**Step-by-step explanation:**

Use the product rule to answer each of the questions below. Throughout, be sure to carefully label any derivative you find by name. It is not necessary to algebraically simplify any of the derivatives you compute.a. Let m (w) = 3 w^17 4^w. Find m ′(w) . b. Let h (t) = ( sin (t) + cos (t)) t 4. Find h ′(t). c. Determine the slope of the tangent line to the curve y = f (x) at the point where a = 1 if f is given by the rule f(x) = e^x sin (x). d. Find the tangent line approximation L(x) to the function y = g (x) at the point where a = − 1 if g is given by the rule g (x) = ( x^2 + x ) 2^x .

Suppose a regional computer center wants to evaluate the performance of its memory system. One measure of performance is the average time between failures of its disk drive. To estimate the value, the center recorded the time between failures for a random sample of 45 drive failures. The sample mean has been computed to be 1,762 hours and the sample standard deviation is 215. Estimate the true mean time between failures with a 90% confidence interval? Interpret the confidence interval.

What reason could you use in a proof to prove two triangles are congruent by SSS?

Which of the following correctly displays 1/2 r - t

Assume that females have pulse rates that are normally distributed with a mean of 74.0 beats per minute and a standard deviation of 12.5 beats per minutes. If 16 adult female is randomly selected, find the probability that her pulse rate is less than 80 beats per minute.

**Answer:**

1.8 times the cost of labor.

**Step-by-step explanation:**

At the beginning of the year, the rate for overhead was estimated to be ...

(overhead $)/(direct labor $) = $396/$220 = 1.8

**The overhead rate is 1.8 times the labor cost**.

**Answer:**

3x (x² + x + 1)

You could write any trinomial like this

If Dan is 8x years old next year then he must be 8x-1 years old this year

With the same logic, five years ago from this year, he must be 8x-1-5=8x-6

The answer should be 8x-6

With the same logic, five years ago from this year, he must be 8x-1-5=8x-6

The answer should be 8x-6

The x is to the 3rd power and the 6 is to the second power. Hope this helps XD

**Step-by-step explanation:**

**Answer:**

The correct option is D.

**Step-by-step explanation:**

The slope of a line is the change in y with respect to x.

If the slope of a line is undefined it means it is a vertical line and a vertical line can not passes through three quadrants. **So, option A is incorrect.**

If the slope of a line is 0 it means it is a horizontal line and a horizontal line can not passes through three quadrants. **So, option B is incorrect.**

If the slope of a line is positive it means the value of y increases as x increases.

Since it is an increasing line, therefore after a certain period both x and y will positive. It means the line will passes through first quadrant. **So, option C is incorrect.**

If the slope of a line is negative it means the value of y decreases as x increases. It can passes through each of Quadrants II, III, and IV.

**Therefore the correct option is D.**
