Answer:
7/4 * pi
Step-by-step explanation:
Area of circle = pi * r^2
Find radius:
pi * 49/64 = pi * r^2
49/64 = r^2
7/8= r
Circumference of circle = 2pi * r
2 * pi * (7/8) = 7/4 * pi
Assuming that the answer is in terms of pi as the question is in terms of pi
46/69 * 100
0.66666*100
which is 66percent
Answer:
18 days
Step-by-step explanation:
Find how many days it can be expected to rain by finding 60 percent of 30
30(0.6)
= 18
So, one can expect it to rain for a total of 18 days out of the 30 days
Given:
The volume of water in a tank is modeled by the function
![y=1.15x^3-0.1x^2+2](https://tex.z-dn.net/?f=y%3D1.15x%5E3-0.1x%5E2%2B2)
where, x is the number of minutes after the faucet filling the tank is turned on.
To find:
The y-intercept and what does it represent in this context?
Solution:
We have,
![y=1.15x^3-0.1x^2+2](https://tex.z-dn.net/?f=y%3D1.15x%5E3-0.1x%5E2%2B2)
Substituting x=0, we get
![y=1.15(0)^3-0.1(0)^2+2](https://tex.z-dn.net/?f=y%3D1.15%280%29%5E3-0.1%280%29%5E2%2B2)
![y=0-0+2](https://tex.z-dn.net/?f=y%3D0-0%2B2)
![y=2](https://tex.z-dn.net/?f=y%3D2)
Therefore, the y-intercept is 2 and it represents the volume of water in a tank before the faucet filling the tank is turned on.
