Answer:
Step 1:
Find the vertex. Since the equation is in vertex form, the vertex will be at the point (h, k).
Step 2:
Find the y-intercept. To find the y-intercept let x = 0 and solve for y.
Step 3:
Find the x-intercept(s). To find the x-intercept let y = 0 and solve for x. You can solve for x by using the square root principle or the quadratic formula (if you simplify the problem into the correct form).
Step 4:
Graph the parabola using the points found in steps 1 – 3.
Step-by-step explanation:
Since the angles are complementary, they add to 90°. So we can write the equation:
x represents the first angle, and 4x represents the second
x+4x=90
5x=90
x=18
So the first angle is 18° and the second is 72° (18*4)

Step-by-step explanation:
The volume of a cone can be found with the following equation:
where 
is the radius of the base and 
is the height of the cone.
For the cone with diameter of 20 units and height of 12 units, the volume is the following:
For the cone with diameter of 18 units and height of 10 units, the volume is the following:
For the cone with diameter of 20 units and height of 12 units, the volume is the following:
