Answer:

The average sales per week for the first 16 weeks is $477 million dollars per week.

Step-by-step explanation:

Here, you have to find the average value of a continuous function over an interval.

Suppose you have a function f(x) over an interval from a to b. The average of the function in this interval is given by:

\frac{1}{b-a}\int\limits^b_a {f(x)} \, dx

Solution:

In this problem, the function is given by:

S(t) = 59t + 5

The problem asks the average value for the first 16 weeks. It means that our interval goes from 0 to 16. So a = 0, b = 16.

The average value is given by the following integral:

A = \frac{1}{16}\int\limits^{16}_{0} {(59t + 5)} \, dt

A = \frac{59t^{2}}{32} + \frac{5t}{16}, 0 \leq t \leq 16

A =\frac{59*(16)^{2}}{32} + \frac{5*16}{16}

A = $477

The average sales per week for the first 16 weeks is $477 million dollars per week.

What is the measure of each interior angle in a regular 30-gon?
Rasek [7]
Exterior angles always add up to 360 degrees so for 30-gon each exterior angles is 12 degrees (360/30)

To get the interior angles you subtract 180 from 12 to get 168 degrees

Solve for x in the triangle. Round your answer to the nearest tenth.
hodyreva [135]

Answer:

x ≈ 11.7

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos26° = \frac{adjacent}{hypotenuse} = \frac{x}{13} ( multiply both sides by 13 )

13 × cos26° = x , then

x ≈ 11.7 ( to the nearest tenth )

If SA=1/2lp+B, find p<br><br> What is the formula for finding p?
Ilia_Sergeevich [38]
<span>You must get p by itself, so first subtract B from both sides: SA-B=1/2lp. Then multiply both sides by 2, which cancels out the 1/2: 2SA=lp. Then divide both sides by l: (2SA)/l=p.</span>
