Answer: It is A=-1<x<-6 is the domain
The answer is 1000000
10^2=100
100^3=1000000
Answer:
- 10 and 60
Step-by-step explanation:
1
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = (3 × - 2) - 4 = - 6 - 4 = - 10
2
To evaluate f(8) substitute x = 8 into f(x)
f(8) = 8² - 4 = 64 - 4 = 60
Yes, because it's on the x axis.
Answer:
3.167353103 meters
Step-by-step explanation:
The volume of a sphere can be found using:
v=4/3πr^3
We know that 133.1 is the volume, so we can substitute 133.1 in for v
133.1=4/3πr^3
To solve for r, we need to get by itself. First, divide both sides by 4/3π
133.1/ 4/3π= 4/3πr^3/ 4/3π
31.7752843883=r^3
Since r is being raised to the 3rd power, take the cubed root of both sides
![\sqrt[3]{31.7752843883}=\sqrt[3]{r^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B31.7752843883%7D%3D%5Csqrt%5B3%5D%7Br%5E3%7D)
3.167353103=r
So, the radius is 3.167353103 meters
