find the volume of the solid formed by revolving the region bounded by the graphs of y = 4x - x^2 and f(x) = x^2 from [0,2] about the... a) x-axis.
Answer:
[tex]v = \frac{32\pi}{3}[/tex]
or
[tex]v=33.52[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 4x - x^2[/tex]
[tex]g(x) = x^2[/tex]
[tex][a,b] = [0,2][/tex]
Required
The volume of the solid formed
Rotating about the x-axis.
Using the washer method to calculate the volume, we have:
[tex]\int dv = \int\limit^b_a \pi(f(x)^2 - g(x)^2) dx[/tex]
Integrate
[tex]v = \int\limit^b_a \pi(f(x)^2 - g(x)^2)\ dx[/tex]
[tex]v = \pi \int\limit^b_a (f(x)^2 - g(x)^2)\ dx[/tex]
Substitute values for a, b, f(x) and g(x)
[tex]v = \pi \int\limit^2_0 ((4x - x^2)^2 - (x^2)^2)\ dx[/tex]
Evaluate the exponents
[tex]v = \pi \int\limit^2_0 (16x^2 - 4x^3 - 4x^3 + x^4 - x^4)\ dx[/tex]
Simplify like terms
[tex]v = \pi \int\limit^2_0 (16x^2 - 8x^3 )\ dx[/tex]
Factor out 8
[tex]v = 8\pi \int\limit^2_0 (2x^2 - x^3 )\ dx[/tex]
Integrate
[tex]v = 8\pi [ \frac{2x^{2+1}}{2+1} - \frac{x^{3+1}}{3+1} ]|\limit^2_0[/tex]
[tex]v = 8\pi [ \frac{2x^{3}}{3} - \frac{x^{4}}{4} ]|\limit^2_0[/tex]
Substitute 2 and 0 for x, respectively
[tex]v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ \frac{2*0^{3}}{3} - \frac{0^{4}}{4} ])[/tex]
[tex]v = 8\pi ([ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ] - [ 0 - 0])[/tex]
[tex]v = 8\pi [ \frac{2*2^{3}}{3} - \frac{2^{4}}{4} ][/tex]
[tex]v = 8\pi [ \frac{16}{3} - \frac{16}{4} ][/tex]
Take LCM
[tex]v = 8\pi [ \frac{16*4- 16 * 3}{12}][/tex]
[tex]v = 8\pi [ \frac{64- 48}{12}][/tex]
[tex]v = 8\pi * \frac{16}{12}[/tex]
Simplify
[tex]v = 8\pi * \frac{4}{3}[/tex]
[tex]v = \frac{32\pi}{3}[/tex]
or
[tex]v=\frac{32}{3} * \frac{22}{7}[/tex]
[tex]v=\frac{32*22}{3*7}[/tex]
[tex]v=\frac{704}{21}[/tex]
[tex]v=33.52[/tex]
A realtor collects the data set given in DS 12.2.4 concerning the sizes of a random selection of newly constructed houses in a certain area together with their appraised values for tax purposes.
1. Fit a linear regression model with appraised value as the explanatory variable and size as the dependent variable.
2. What is the estimate of the error variance?
Answer:
12.327X + 452.084
45206.327
Step-by-step explanation:
The linear regression model obtained by fitting the data using technology is :
ŷ = 12.327X + 452.084
Where, 12.327 = slope ; 452.084 = Intercept ; X = appraised value ; y = Area
The estimated error variance which is the degree of variation between the actual and predicted value.
Error variance = ΣSSE /n-2
n = sample size = 15
ΣSSE = 587682.2638
Error variance = 587682.2638/13
Error variance = 45206.327
Which statement describes the piecewise function when x = -6?
-2,15-6
160=425-18, 17-0
O Since lim (a) = 36 and f(x) = 36, the function is continuous when x=-6.
O Since lim f(x) = -36 and f(x) = -36, the function is continuous when x = -6.
O Since lim f(x) = -36 and f(x) = 36, the function is not continuous whenx=-6.

How do we decide if a situation requires us to measure in square units or cubic units?
Answer: see below...
Step-by-step explanation:
Square units are when we are finding the surface area.
Since it is side x side, so ^2.
Cubic units are when we are finding the volume.
Since it is side x side x side, so ^3.

Angle A and angle B are supplementary angles. if Angle A is 35 degrees, how big is angle B (Btw Angle B is just a straight line. Angle A is 35 degrees) Plz help me
Answer:
145
Step-by-step explanation:
So lets recall what a supplementary angle is. A suppelemenatry angle is two angles that make up 180 degrees.(half circle)
This is different from a complenenary angle with is two angles that make up 90 degrees(quarter circle)
Ok, so we can write the equation for the supplementary angle as:
35+b=180
Lets subtract the angle we knwo from both sides:
b=145
Now we know that B(second angle) must be equal to 145 degrees.
Hope this helps!

A square sheet of rubber has sides that are 20 cm long. What is the area of the square of rubber in cm squared?
Area of the square of rubber =?
Answer:
[tex]area \: = side \times side \\ area = 20 \times 20 \\ area = 400 \: {cm}^{2} [/tex]
Answer:
400cm^2
Sides are 20cm long Area for square is a squared since all the lides are of equal length you can just choose one side.

Answer:
1/192
Step-by-step explanation:
So, lets go over what we know:
There are 24 different sections on the circle.
3 of them are 500$.
1 of them are lose a turn.
Now, to find the answer, here is what we have to remember.
There are two different things you work with when solving this area of geometry.
"and" and "or"
When they say "or", you have two seperate chances, these chances need to be added together.
When they say "and", like in this question, you have two chances in the same thing. These chances need to be multiplyied together.
If this is a bit confusing, think of this another way:
When "or" = add one chance from the other.
In this case:
3/24 + 1/24=4/24.
However, "and" = multiply one chance by the other.
In this case:
3/24*1/24 = 3/576
This question is using "and". So our answer is:
3/576
This can be simplyfied as:
1/192
So this is our answer!
Hope this isnt to confusing and helps! :D

Find the slope and y-intercept of the equation.
y + 7 = 4x
slope: 7
&
y-intercept: 4
slope: 4
&
y-intercept: -7
slope: 4
&
y-intercept: 7
slope: -4
& y-intercept: 7
Answer:
slope: 4
Y-intercept: -7
Step-by-step explanation:
you would have to solve for y so you subtract the 7 on both sides. then it is in slope-intercept form which is y=mx+b where m is slope and b is the y-intercept. the slope would be 4 and the y-intercept would be -7
