Answer:
48
Step-by-step explanation:
![y = 0](https://tex.z-dn.net/?f=y%20%3D%200)
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](https://tex.z-dn.net/?f=y%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%2025)
We then get
![\frac{ {x}^{3} }{3} - 25x](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7Bx%7D%5E%7B3%7D%20%7D%7B3%7D%20%20-%2025x)
Evaluate at -3
![\frac{ - 3 {}^{3} }{3} - 25( - 3)](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%203%20%7B%7D%5E%7B3%7D%20%7D%7B3%7D%20%20-%2025%28%20-%203%29)
![- 27 + 75 = 48](https://tex.z-dn.net/?f=%20-%2027%20%2B%2075%20%3D%2048)
Then we evaluate at 0
![\frac{0 {}^{3} }{3} - 25(0) = 0](https://tex.z-dn.net/?f=%20%5Cfrac%7B0%20%7B%7D%5E%7B3%7D%20%7D%7B3%7D%20%20-%2025%280%29%20%3D%200)
Next, we subtract the the answer then we get
![48 - 0 = 48](https://tex.z-dn.net/?f=48%20-%200%20%3D%2048)
Answer:
x=36
2x=72
4x=144
Step-by-step explanation:
Remember that the sum of all the inside angles of a triangle = 180
so angle E is 180-2x
and angle F is 180-4x
If you add angles E, F, and G, they need to add to 180.
substituting, we get 180-2x + 180-4x + x = 180.
Simplifying this, we get 180-5x = 0
and x=180/5 = 36
so if x=36, then 2x=72 and 4x=144
Answer:
a. 60 boys
b. 228 total students
Step-by-step explanation:
a. If there are 45 girls and the ratio of girls to boys is 3:4, then there are 60 boys. The common multiple is 15.
3 * 15 = 45
4 * 15 = 60
45:60 = 3:4
——————————
b. First we need to find out how many boys there are.
95 / 5 = 19
19 * 7 = 133
So, there are 133 boys and the given number of girls is 95. To find out how many total students there are, we need to add 133 and 95.
133 + 95 = 228
