Answer:
Step-by-step explanation:
Formula
V = (1/3) pi * r^2 * h Substitute the givens into the formula
Givens
V = ?
pi = 3.14
r = 3 in
h = 18 in
Solution
V = 1/3 * 3.14 * 3 * 3 * 18
V = 169.56
Answer
V = 169.56 in^2
The point-slope form equation for this line is
y₁ - 9 = 4 (x₁ - 1), or D.Since these are all in point-slope form, all we need to do is find the slope and then input one value of (x, y) into the points. We start with the slope.
m =

m =

m =

m = 2
Now we need to input the values of one of the points and slope into the point slope equation: y₁ - y = m(x₁ - x).
Inputting (1, 9), we get
y₁ - 9 = 4 (x₁ - 1)
The equation that fits it is D., so that means that the only answer to this question is
D.
Answer:
$11988
Step-by-step explanation:
Given that,
The unit cost is given by :

We need to find the minimum unit cost.
For minimum cost,
Put 
So,

Put x = 330 in equation (1).

So, the minimum unit cost is equal to $11988.
Prove that if m + n and n + p are even integers, where m, n, and p are integers, then m + p is even.
m=2k-n, p=2l-n
Let m+n and n+p be even integers, thus m+n=2k and n+p=2l by definition of even
m+p= 2k-n + 2l-n substitution
= 2k+2l-2n
=2 (k+l-n)
=2x, where x=k+l-n ∈Z (integers)
Hence, m+p is even by direct proof.
Answer:
A. (-5, 0) and (-2, 0)
Step-by-step explanation:
Assuming you mean x^2 + 7x + 10. Simply graph using Desmos and locate where the graph crosses the x-axis! :)
