Ilia_Sergeevich [38]

Answer:

She donated b/50 books

Step-by-step explanation:

In this question, we are we are told 150 students donated a total of b books. The average number of books donated by each student will be:

The total number of books/ the total number of students.

The average number of books is this b/150.

Now, we are also told that Hannah donated 3 times the average number of books.

This is simply calculated by multiplying the average number of books donated by 3

This is equal to 3 * b/150 = b/50 books

Hence, Hannah donated b/650 books

Find the area between y=(x-2)ex and the x-axis from x=2 to x=4.
mojhsa [17]

Answer:

e^4+e^2

Step-by-step explanation:

It can be found by integral.

First let's find the intersection points.

(x-2)e^x = 0

Only intersection point is x = 2.

And it is asked to find the area in the interval (2, 4).

\int\limits^4_2 (x-2)e^x \,dx=?

We will use integration by parts.

x-2=u\\dx=du\\e^xdx=dv\\e^x=v

\int\limits^4_2 (x-2)e^x \,dx=uv-\int vdu=(x-2)e^x-\int e^xdx=(x-2)e^x-e^x=\\\\=(x-3)e^x|^4_2=(4-3)e^4-(2-3)e^2=e^4+e^2
