Answer:

A (3/2, 9/2)

Step-by-step explanation:

Let's take the first solution which is (3/2 , 9/2). If we substitute 3/2 into x we get the equation (3/2)^2 we get y as 9/4 not 9/2, therefore (3/2 , 9/2) does not lie on the curve y = x^2

Answer:

see below

Step-by-step explanation:

y = x^2

Substitute the points in and see if it is true

y = (3/2) ^2 = 9/4  not true

y = (-1) ^2 = 1   true

y = (4) ^2 = 16   true

y = (1/2) ^2 = 1/4   true

Jim rented a truck for one day. there was a base fee for $19.95 and there was an additional charge of 91 cents for each mile dri
beks73 [17]
First you’ll subtract the base fee, which is 19.95 from the price payed, 243.81

243.81
-19.95
223.86

Now take 223.86, your remainder and divide it by .91, you will get 246, meaning Jim traveled 246 miles.

Answer: Jim travelled 246 Miles.

There is no such number.

Note that  36x = 9 results in x = 9/36 or x = 1/4.

Could you possibly share an example of this type of problem?  Right now it doesn't make sense to me.

Use the method of cylindrical shells to find the volume generated by rotating the region bounded by the given curves about the s
Furkat [3]

Answer:

\frac{16\pi}{3}.

Step-by-step explanation:

I graphed the region in the image below. The blue line is y=3, the purple line is x=1 and the green curve is y = 4x-x^{2}. The shaded region in blue is the region we are going to rotate.

Now, to find the volume  v= 2\pi \int\limits^a_b {p(x)h(x)} \, dx where a=1, b=3 (left and right points of the region), p(x) is the distance from the rotation axis to the diferential Δx, we say p(x)=x and h(x) is the height of the region, in this case is h(x)= 4x-x^{2}-3. Then,

v =  2\pi \int\limits^1_3 {x(4x-x^{2}-3)} \, dx

=  2\pi \int\limits^1_3 {4x^{2}-x^{3}-3x} \, dx

= 2\pi (\frac{4x^{3}}{3}-\frac{x^{4}}{4}-\frac{3x^{2}}{2})^{3}_1

= 2\pi (36-\frac{81}{4}-\frac{27}{2}-\frac{4}{3}+\frac{1}{4}+\frac{3}{2})

= 2\pi*\frac{8}{3}

=  \frac{16\pi}{3}.
