Answer:

many solutions

Step-by-step explanation:

You have to attribute values to x, and then you find the y value.

The x value you attributed and the y value you got as a result will be an ordered pair of the linear equation

For example:

x = 4

y = 3*4-7

y = 5

(4 | 5) is an ordered pair.

x = 3

y = 3*5-7

y = 8

(3 | 8) is another one.

Find the volume of the solid generated by revolving the region bounded by the lines and curves about the x-axis. y = x, y =1, x

liraira [26]

Answer:

The volume is: $V = \frac{\pi}{3}$ cubic units

Step-by-step explanation:

Volume of a solid:

The volume of a solid, given by the function f(x), over an interval between a and b, is given by:

$V = \pi \int_{a}^{b} (f(x))^2 dx$

y = x, y =1, x = 0

This means that the upper function is y = 1, and the lower function is y = x. So

$f(x) = (1 - x)$

The lower limit of integration is x = 0.

The upper limit is y = x when y = 1, so x = 1.

Then

$V = \pi \int_{a}^{b} (f(x))^2 dx$

$V = \pi \int_{0}^{1} (1-x)^2 dx$

$V = \pi \int_{0}^{1} (1-2x+x^2) dx$

$V = \pi (x-x^2+\frac{x^3}{3})|_{0}^{1} dx$

$V = \pi(1 - (1^2) + \frac{1^3}{3})$

$V = \frac{\pi}{3}$

In a certain class of students, there are 11 boys from Wilmette, 7 girls from Wilmette, 5 boys from Winnetka, 4 girls from

attashe74 [19]

Answer:

.571

Step-by-step explanation:

We need to find the total number of boys

11+5+4 = 20

And the total number of students

11+7+5+4+4+4 = 35

The Probability that the student is a boy is boy/total

P (boy) = boy/total

= 20/35

=4/7

=.571428571

to 3 decimal places

=.571
