Answer:
0.8 4
3.2 16
12.8 64
Step-by-step explanation:
Proportional means that it will have a constant rate of change. If we divide 4/0.8 in the first example, we get 5. In the second example, we need to find x/3.2=5. 16/3.2=5. In the third example, we need to find 2 numbers divided by each other that equals 5. 64/12.8=5
Answer:
x^3 - x^2 + 11x - 1
-x^3 - 8x^2 + 5x + 7
Step-by-step explanation:
Find the sum
(x^3+5x^2+3x-7)+(8x-6x^2+6)
=x^3+5x^2+3x-7+8x-6x^+6
Collect like terms
=x^3 +5x^2-6x^2+3x+8x-7+6
Add the like terms
= x^3 - x^2 + 11x - 1
Find the difference (7x-3x^2+2)-(x^3+5x^2+2x-5)
(7x-3x^2+2)-(x^3+5x^2+2x-5)
= 7x-3x^2+2-x^3-5x^2-2x+5
Collect like terms
= -x^3-3x^2-5x^2+7x-2x+2+5
Add the like terms
= -x^3 - 8x^2 + 5x + 7
Let's solve this problem step by step.
−2(1−3x)=22−3(x−13)
Step 1: Simplify both sides of the equation.
(−2)(1)+(−2)(−3x)=22+(−3)(x)+(−3)(−13)(Distribute)
−2+6x=22+−3x+39
6x−2=(−3x)+(22+39)(Combine Like Terms)
6x−2=−3x+61
Step 2: Add 3x to both sides.
6x−2+3x=−3x+61+3x
9x−2=61
Step 3: Add 2 to both sides.
9x−2+2=61+2
9x=63
Step 4: Divide both sides by 9.
9x/9=63/9
So, the answer to this problem is x=7.

Step-by-step explanation:
![V = \int_0^7 A(x)\, dx = \int_0^7 \pi(x+1)^2dx = \int_0^7 \pi(x^2 + 2x + 1)dx \\ \\ = \pi \left[ \frac{1}{3}x^3 + x^2 + x\right]_0^7 = \pi\left( \frac{1}{3}(7)^3 + 7^2 + 7\right) = \frac{511}{3}\pi](https://tex.z-dn.net/?f=V%20%3D%20%5Cint_0%5E7%20A%28x%29%5C%2C%20dx%20%3D%20%5Cint_0%5E7%20%5Cpi%28x%2B1%29%5E2dx%20%3D%20%5Cint_0%5E7%20%5Cpi%28x%5E2%20%2B%202x%20%2B%201%29dx%20%20%5C%5C%20%5C%5C%0A%3D%20%5Cpi%20%5Cleft%5B%20%5Cfrac%7B1%7D%7B3%7Dx%5E3%20%2B%20x%5E2%20%2B%20x%5Cright%5D_0%5E7%20%3D%20%5Cpi%5Cleft%28%20%5Cfrac%7B1%7D%7B3%7D%287%29%5E3%20%2B%207%5E2%20%2B%207%5Cright%29%20%3D%20%5Cfrac%7B511%7D%7B3%7D%5Cpi)
