Answer:
Step-by-step explanation:
<u>Given</u>
- f(x) = 2x^2 + 6x – 4
- g(x) = 5x^3 – 6x^2-3
<u>
To find </u>
<u>Solution</u>
- (f +g)(x) = f(x) + g(x) =
- 2x^2 + 6x - 4 + 5x^3 - 6x^2 - 3 =
- 5x^3 - 4x^2 + 6x - 7
72.26 is the answer I think
Answer:
The volume of the cone is 12936 cubic mm.
Step-by-step explanation:
Given
Circumference of base = 132 mm
Height of the cone = 28 mm
Solution
Formula of circumference =
= 132 mm

Now volume of cone = 
on substituting the value of r and h we get ;

thus volume of cone is 12936 cubic mm.
Option D should be your answer.
No combo of any of those angles add up to exactly 180 to suggest that they are parallel lines.
