Step-by-step explanation:
Since we have a vertical major axis, our ellipse is vertical.
The equation of a vertical ellipse is
where
(h,k) is the center
a is the semi major axis,
b is the semi minor axis
First, let plug in our center
Semi means half, so
a is half of 14 which is 7
B is half of 8, which is 4.
This is a special right triangle called a 30-60-90 triangle. It has a special property the relates the ratio of side lengths. That ratio is 1:
:2
What does this mean? If you know the shortest side of a 30-60-90 triangle, you can find the longer leg by multiplying it by
, and you can find the hypotenuse by multiplying the short leg by 2.
In the picture, note that the short leg of the triangle has a length of 9. Therefore, the long leg(or n) is simply 9
Answer:
10
Step-by-step explanation:
1/2×(-2-(-7))×(6-(-4))
Is the 10 taking away 5 or was it meant to me 10.5 ?
Answer:
Volume of cone = (1/3) * Volume of cylinder
Step-by-step explanation:
Use the formulas
Volume of cone = (1/3)* π r^2 *h
Volume of cylinder = π r^2 *h
Therefore
Volume of cone = (1/3) * Volume of cylinder
