olchik [2.2K]

Answer:

D. AO

Step-by-step explanation:

The radius can be made with a line from a point in the circumference (end) to the middle.

Point A is on the circumference. Point O is in the middle. So, line segment AO is the radius.

The rate of sales for a corporation t weeks from now is given by S(t)=59t+5 millions of dollars per week. Find the average sales

8090 [49]

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.

Simplify 81^5=3^w and find w

Allisa [31]

Answer:

$w = 20$

Step-by-step explanation:

<u>Step 1: Find common bases</u>

$81^5 = 3^w$

$81$ → $3 * 3 * 3 * 3$ → $3^4$

Therefore, $81 = 3^4$

$81^5$ → $3^(^4^)^*^5$ → $3^2^0$

So... $3^2^0 = 3^w$

Since same base now, we can evaluate the exponents by themselves.

$20 = w$

Answer: $w = 20$
