Answer:
1130040
Step-by-step explanation:
so what your going to do is it sounds like 3 turns = 3 hours so 1 turn= 1 year so theres 8760 hours in a year so thats going to be 8760 turns now multiply thar by 129 and you get your awnser.
Answer:
1 5/18
one and five eighteenths
Step-by-step explanation:
The answer is 3.04800 meters.
Why you may ask? Well 1ft = 0.3048 meters so you calculate 10 ft based off this measurement and you get 3.04800 meters.
CHEERS MATE!
Answer:
Step-by-step explanation:
510 pieces of candy, and candies can be sold in bags of 10.
Dividing 10 into 510 will give us our answer, which is 51.
First, let me introduce the general equation of the parabola:
(x-h)^2 = +/- 4a(y-k) or (y-k)^2=+/- 4a(x-h), where
(h,k) are the coordinates of the vertex
a is the distance of the vertex to the focus
4a = length of lactus rectum or the focal width
If the equation contains (x-h)^2, then the parabola passes the x-axis twice. Similarly, (y-k)^2 passes the y-axis twice. If the sign is (-), it opens to the left(if y-axis) or downward (if x-axis). If the sign is (+), it opens to the right(if y-axis) or upward (if x-axis).
The equation of the parabola is -1/12 x^2 = y. Rearranging to the general form:
x^2 = -12y
Therefore,
-4a = -12
4a = 12
a = 3, and the parabola is facing downwards.
The vertex is (0,0) at the origin.
The focus is (0,-3). Since it is negative, the focus is situated downwards, hence -3.
The directrix is the mirror image of the focus. Hence, it is a line passing +3 on the y-axis. y=3
Focal width is 4a which is equal to 12 units.
