Hi this is mikayla Cheney from school
I think it would be
(23/x) = 249
Answer:
![y-5=\frac{1}{2}(x+2)](https://tex.z-dn.net/?f=y-5%3D%5Cfrac%7B1%7D%7B2%7D%28x%2B2%29)
Step-by-step explanation:
Point Slope is:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
We are given the point (-2, 5) and a slope of 1/2.
![y-y_1=m(x-x_1)\rightarrow\boxed{y-5=\frac{1}{2}(x+2)}](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29%5Crightarrow%5Cboxed%7By-5%3D%5Cfrac%7B1%7D%7B2%7D%28x%2B2%29%7D)
Hope this helps.
Answer:
Yes, I agree
Step-by-step explanation:
See attachments for cone
Cone A
![h = 2r](https://tex.z-dn.net/?f=h%20%3D%202r)
Cone B
R = 2r
![h=r](https://tex.z-dn.net/?f=h%3Dr)
The volume of a cone is
![V = \frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
For cone A, we have:
![V = \frac{1}{3}\pi r^2*2r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%2A2r)
![V_A = \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
For cone B, we have:
![V = \frac{1}{3}\pi *(2r)^2 * r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%2A%282r%29%5E2%20%2A%20r)
![V = \frac{1}{3}\pi *4r^2 * r](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%2A4r%5E2%20%2A%20r)
![V_B = \frac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V_B%20%3D%20%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
So, we have:
![V_B = 2 * \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_B%20%3D%202%20%2A%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
Substitute ![V_A = \frac{2}{3}\pi r^3](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B2%7D%7B3%7D%5Cpi%20r%5E3)
![V_B = 2 * V_A](https://tex.z-dn.net/?f=V_B%20%3D%202%20%2A%20V_A)
Make VA the subject
![V_A = \frac{1}{2}V_B](https://tex.z-dn.net/?f=V_A%20%3D%20%5Cfrac%7B1%7D%7B2%7DV_B)
Hence, I agree with Ahmad
