Step-by-step explanation:
Known points
Endpoint: (-6,-3) and midpoint (-5,-5)
Hint: Use the midpoint formula,substitute the known values and solve separately.
![midpoint = ( \frac{x1 + x2}{2} . \frac{y1 + y2}{2} )](https://tex.z-dn.net/?f=midpoint%20%3D%20%28%20%5Cfrac%7Bx1%20%2B%20x2%7D%7B2%7D%20.%20%5Cfrac%7By1%20%2B%20y2%7D%7B2%7D%20%29)

Answer:
Distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh
Explanation:
Distance traveled by a body = Velocity of the body * Time taken by the body
Here velocity of Sierra = 2x miles per hour
Time taken by Sierra = h hours.
Distance traveled by Sierra = 2x * h = 2xh
So distance traveled by Sierra in h hours at a rate of 2x miles per hour = 2xh
Answer:
![h=\frac{79^3 * 3}{25\pi}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B79%5E3%20%2A%203%7D%7B25%5Cpi%7D)
Step-by-step explanation:
Here, we have to find the value for h, in terms of
.
Assuming The equation is:
![79^3=\frac{\pi*25*h}{3}](https://tex.z-dn.net/?f=79%5E3%3D%5Cfrac%7B%5Cpi%2A25%2Ah%7D%7B3%7D)
We cross multiply to get:
![79^3=\frac{\pi*25*h}{3}\\79^3 * 3 = 25\pi h\\](https://tex.z-dn.net/?f=79%5E3%3D%5Cfrac%7B%5Cpi%2A25%2Ah%7D%7B3%7D%5C%5C79%5E3%20%2A%203%20%3D%2025%5Cpi%20h%5C%5C)
Now, we divide both sides by
to get an expression of h in terms of
:
![h=\frac{79^3 * 3}{25\pi}](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B79%5E3%20%2A%203%7D%7B25%5Cpi%7D)
