Answer:
The answer to your question is: A = 282.6 in²
Step-by-step explanation:
Data
height = 9 in
radius = 5 in
Formula
A = 2πrh
Process
A = 2(3.14)(5)(9)
A = 282.6 in²
36 donuts (2 1/2 dozen) = $8.00
So, you divide 8 by 36 and you get about 22¢ for each donut. Then, you do .22 x 12 which equals $2.64.
One dozen donuts = $2.64
Answer:
16
Step-by-step explanation:
64 divided by 4 is 16. Paul has 16 baseball cards.
Answer:
![x^{2} =3y](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D3y)
Step-by-step explanation:
Notice that the focus is a points on the vertical axis, that means the parabolla opens vertically, and has the form
![x^{2} =4py](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D4py)
Because the parameter
is positive and equal to 0.75. Additionally, the vertex is at the origin, that's why the equation is this simple.
Replacing the parameter value, we have
![x^{2} =4(0.75)y\\x^{2} =3y](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D4%280.75%29y%5C%5Cx%5E%7B2%7D%20%3D3y)
Therefore, the equation of a parabolla with vertex at the origin and focus at (0, 0.75) is
.
