Find the area bounded by the graphs of the indicated equations over the given interval.

NeX [460]

Answer:

Step-by-step explanation:

$y = 0$

is basically the horizontal axis.

First, find the integral of x^2-25.

Remember that

integral of a constant is that constant times x.

Also that

to take the integral of a power function, add 1 to the degree and divide by that same degree.

$y = {x}^{2} - 25$

We then get

$\frac{ {x}^{3} }{3} - 25x$

Evaluate at -3

$\frac{ - 3 {}^{3} }{3} - 25( - 3)$

$- 27 + 75 = 48$

Then we evaluate at 0

$\frac{0 {}^{3} }{3} - 25(0) = 0$

Next, we subtract the the answer then we get

$48 - 0 = 48$

How do you find surface area of a triangular prism ?

RSB [31]

The formula to find the surface area of a triangular prism is basically finding out the area of one of the faces of a traingle, which is:

 $(base)*(height)/2$

So, basically you take the face of the triangle that your trying to find the surface area of and plug in your values for the base length and height, multiply them together, hen divide that product by 2 to find your surface area :)

Thank you for the question! I hope this helped! Have an amazing day!! :D

Callie got 37 pieces of Halloween candy. Her brother got 42 pieces. She wants to estimate to find about how many pieces of candy

Vikki [24]

Answer:

Callie needs to hide both her and her brother's candy from him so that none is eaten/stolen. Then count each stash separately. Put the candies in groups of 10 to quickly establish that over 70 pieces were collected. Callie should steal a stack from her brother's pile while he's not looking. Just calmly shift one stack of ten candies to her side. She should announce she got 47 pieces and her brother only 32.
