Answer:
Beans Jing bought=17b
Step-by-step explanation:
You multiply 17 by the m=number of beans per bag, this makes the equation 17b.
Answer:
true
Step-by-step explanation:
use the pythagorean theorem
The area of the circle by definition is given by:
![f (r) = \pi * r ^ 2 ](https://tex.z-dn.net/?f=%20f%20%28r%29%20%3D%20%20%5Cpi%20%20%2A%20r%20%5E%202%0A)
For f (r) = 154:
![154 = \pi * r ^ 2 ](https://tex.z-dn.net/?f=%20154%20%3D%20%20%5Cpi%20%20%2A%20r%20%5E%202%0A)
Clearing r we have:
![r ^ 2 = 154 / 3.14 r = \sqrt{154/3.14} r = 7](https://tex.z-dn.net/?f=%20r%20%5E%202%20%3D%20154%20%2F%203.14%0A%0A%20r%20%3D%20%20%5Csqrt%7B154%2F3.14%7D%20%0A%0A%20r%20%3D%207)
For f (r) = 616:
![616 = \pi * r ^ 2](https://tex.z-dn.net/?f=%20616%20%3D%20%5Cpi%20%2A%20r%20%5E%202%20)
Clearing r we have:
Answer:
a reasonable domain for f (r) is:
7 <r <14
Answer:
25
Step-by-step explanation:
Firstly, you want to multiply (f^4)^2. ![\frac{2*f^8*f^2}{8f^{12}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%2Af%5E8%2Af%5E2%7D%7B8f%5E%7B12%7D%7D%20%20)
Next, multiply everything on the numerator. ![\frac{2f^{10}}{8f^{12}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2f%5E%7B10%7D%7D%7B8f%5E%7B12%7D%7D%20)
Next, divide. ![\frac{2f^{10}}{8f^{12}}=\frac{1}{4} f^{-2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2f%5E%7B10%7D%7D%7B8f%5E%7B12%7D%7D%3D%5Cfrac%7B1%7D%7B4%7D%20f%5E%7B-2%7D%20)
Now remember that f^-2 = (1/f^2), so just convert the negative powered exponent to that, and your answer will be ![\frac{1}{4f^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4f%5E2%7D%20%20)
