Answer:
225/4
Step-by-step explanation:
x^2+15x+c
take half of 15 and square it
(15/2)^2
225/4
Answer:
f(x)=x-3
Step-by-step explanation:
You are given x-y=3 and you want to rewrite in function notation with x being the independent. That means we need to solve for y so y can depend on x.
x-y=3
Subtract x on both sides:
-y=-x+3
Multiply both sides by -1:
y=x -3
So function notation would be f(x)=x-3
Answer: You need to give more information for me to able to properly answer this question.
Step-by-step explanation:
Answer:
≅217.82
Step-by-step explanation:
The volume of a cone of radius 4 is one third the area of the base B multiplied by the height (13).
therefore;
V = 1/3πr²h
Substituting the values in the equation gives;
V = 1/3π(4)²(13)
V ≅ 217.82 cubic units
Answer:
Step-by-step explanation:
15−x+y=14−(−x−y)
15-x+y=14+x+y
<em>Subtract 14 from both sides</em>
1-x+y=x+y
<em>Subtract y from both sides</em>
1-x=x
<em>Add x to both sides</em>
1=2x
2x=1
<em>Divide both sides by 2</em>
x=0.5
