Find the area bounded by the graphs of the indicated equations over the given interval.
NeX [460]

Answer:

48

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

3/10 divided by -1/3
Snezhnost [94]

Answer:

-9/10

Step-by-step explanation:

  1. Find the LCM of 10 and 3: 30
  2. Alter the numerators to fit the denominators: 3 × 3 = 9, -1 × 10 = -10
  3. Re-write the fractions: 9/30 ÷ -10/30
  4. 9/30 ÷ -10/30 = 9/30 × -30/10
  5. 9/30 × -30/10 = -270/300
  6. -\frac{270}{300} = -\frac{9}{10}  

I hope this helps!
