2/4 or 1/2 (simplified) is your answer
The volume of a cone is
V = (1/3) π r² h
where r = radius of the base
h = the height.
The volume of the frustum is
(1/3)π(7.5²)(11+8) - (1/3)π(3.5²)(8)
=(1/3)π(7.5²)(19) - (1/3)π(3.5²)(8)
The 3rd choice is the correct answer.
Answer:
Answer:
12
Step-by-step explanation:
P(x) has infinitely many solutions, but I am going to find the easiest one, which would be a linear equation.
First, notice that x-2 perfectly divides into itself.
Then, if you add 12 to x-2, you will end up with a remainder of 12. Therefore, P(x) would be x-2+12 = x+10.
Now that we know P(x), we can directly plugin 2 to find out P(2):
2+10 = 12
Therefore, P(2) = 12.
Substitution method
y = x + 3 (*)
y = 3x + 1 (**)
Substitute (*) to (**):
3x + 1 = x + 3 <em>subtract 1 from both sides</em>
3x = x + 2 <em>subtract x from both sides</em>
2x = 2 <em>divide both sides by 2</em>
<h3>x = 1</h3>
Put the value of x to (*):
y = 1 + 3
<h3>y = 4</h3><h3>Answer: x = 1 and y = 4 → (1, 4).</h3>
3rd one there cant be anything under or over a line so it cant be the circle or the parabola so it has to be the 3rd one
