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.

Umnica [9.8K]

Inspired by the works of Neil Dawson and Bert Flugelman, Kassidy drafts a design for a modern sculpture, the amount of steel Kassidy will need is mathematically given as

SA=16.094711 ft^2

<h3>What is the amount of steel Kassidy will need to create the sculpture if the base of the sculpture is 4-feet tall and has a 2-foot diameter.?</h3>

Generally, the equation for the surface area of a cone is mathematically given as

SA=πr(rπ+√(h^2+r^2))

Therefore

SA=πr(rπ+√(h^2+r^2))

SA=π*1(1+√(4^2+1^2))

SA=16.094711 ft^2

In conclusion,  the amount of steel Kassidy will need is

SA=16.094711 ft^2
