Answer:
268 units³
Step-by-step explanation:
V = 4/3 (pi)r³
V = 4/3 (3.14) (4³)
V = 4/3 (3.14) (64)
V = 4/3 (200.96)
V = 268
Answer:
![y = - \frac{1}{12} {x}^{2}](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B12%7D%20%7Bx%7D%5E%7B2%7D%20)
Step-by-step explanation:
We want to find the equation of a parabola withfocus at (-3,0) and directrix y=3.
This para has its vertex at the origin and opens downward.
The equation is of the form
![{x}^{2} = - 4py](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20-%204py)
Where p is the distance from the vertex to the focus.
This distance is p=|0-3|=3
We substitute p=3 to obtain:
![{x}^{2} = - 4 \times 3y](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20-%204%20%5Ctimes%203y)
![{x}^{2} = -12y](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%3D%20-12y)
Hence the equation is
![y = - \frac{1}{12} {x}^{2}](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B12%7D%20%20%7Bx%7D%5E%7B2%7D%20)
610 - 187 is 423 is your subtracting then that should be the difference
Answer:
The measurement of angle B is 135°
The measurement of angle A is 60°
The measurement of angle C is 75°
Step-by-step explanation:
Angle A is the same value of 60, Angle B is pretty much just 180 - 45, and so is angle C.
