The prime factorization of any number means to get the factors of the number in simplest form.

99 = 3 x 33

We have 33 that needs to be factored.

33 = 3 x 11

We now have:

3 x 3 x 11

3^2 x 11 is your prime factorization (from the given answers).

I hope this helps!

Let V be the volume of the solid obtained by rotating about the y-axis the region bounded y = 4x and y = x2/4 . Find V by slicin
aliya0001 [1]

Answer:

Step-by-step explanation:

Consider the graphs of the y = 4x  and  y = \frac{x^{2} }{4}.

By equating the expressions, the intersection points of the graphs can be found and in this way delimit the area that will rotate around the Y axis.

4x = \frac{x^{2} }{4} \\   x^{2}  = 16x \\ x^{2}  - 16x = 0 \\   x(x-16) = 0 then x=0  o  x=16. Therefore the integration limits are:

y = 4(0) = 0  and  y = 4(16) = 64

The inverse functions are given by:

x = 2 \sqrt{y}  and  x = \frac{y}{4}. Then

The volume of the solid of revolution is given by:

\int\limits^{64}_ {0} \, [2\sqrt{y} - \frac{y}{4}]^{2}  dy = \int\limits^{64}_ {0} \, [4y - y^{3/2} + \frac{y^{2}}{16} ]\  dy = [2y^{2} - \frac{2}{5}y^{5/2} + \frac{y^{3}}{48} ]\limits^{64}_ {0} = 546.133 u^{2}

Can someone help me with this question?

The y-intercept (where x = 0) of the equation is at -20.

For every 60 the x runs, the y falls by -10. Use rise over run to determine the slope of the equation.

\frac{-10}{60} = - \frac{1}{6}

Slope-intercept form is determined by the following equation:

y = mx + b

m is your slope, and b is your y-intercept.

Plug the slope and y-intercept into the equation.

y =  -\frac{1}{6}x - 20
