Answer:
Step-by-step explanation:
3x-4y+2=9
-4y= -3x +7
y=3/4 x -7/4
When y=0
0=3/4 x - 7/4
3/4x = 7/4
x=7/3
Therefore solution is (7/3, 0)
Answer:
![n=3](https://tex.z-dn.net/?f=n%3D3)
Step-by-step explanation:
Note that
.
Aha! We see a path to the solution!
We now know that our equation is actually
.
We can divide both sides by
to get
.
By inspection or taking the logarithm base 2 of both sides, we see that
.
So, the answer is
and we're done!
The dotted lines indicate that this object is a sphere, so we will use the formula for finding the volume of a sphere to solve this problem.
Volume of a sphere: 4/3
r³
The figure shows us that the radius of the sphere is 2.8 cm, so we will plug in 2.8 for r in the formula.
4/3
2.8³ = 91.95
The volume of the figure is 91.95 cm³.
