Answer:
C= 10.6
Step-by-step explanation:
AB^2=AC^2+CB^2
C^2=7^2+8^2
C^2= 113
√113=10.630
Answer:
He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.
To determine how many he can burrow in 7 minutes, you would multiply the
unit rate of 3 holes in 1 minute by 7.
He would burrow 21 holes in 7 minutes.

Step-by-step explanation:
This is the formula to find satellite's escape velocity V , where R is earth's radius, h is the satellite's height from the earth surface and g is the earth's gravitational constant.
(Multiplying to clear the fractions)
(R+h)![V^{2} =R^{2} 2g](https://tex.z-dn.net/?f=V%5E%7B2%7D%20%3DR%5E%7B2%7D%202g)
![R+h=\frac{2R^{2}g }{V^{2} }](https://tex.z-dn.net/?f=R%2Bh%3D%5Cfrac%7B2R%5E%7B2%7Dg%20%7D%7BV%5E%7B2%7D%20%7D)
![h= \frac{2R^{2} g}{V^{2} } -R](https://tex.z-dn.net/?f=h%3D%20%5Cfrac%7B2R%5E%7B2%7D%20g%7D%7BV%5E%7B2%7D%20%7D%20-R)
Now, we can determine height of satellite from the surface of the earth
by putting the values in above equation
![h= \frac{2 * (3960)^{2}*32.2 }{6.5^{2} } -3960\\h= 23.902 x10^{6} - 3960\\ h=23.89x10^{6} ft](https://tex.z-dn.net/?f=h%3D%20%5Cfrac%7B2%20%2A%20%283960%29%5E%7B2%7D%2A32.2%20%7D%7B6.5%5E%7B2%7D%20%7D%20-3960%5C%5Ch%3D%2023.902%20x10%5E%7B6%7D%20-%203960%5C%5C%20h%3D23.89x10%5E%7B6%7D%20ft)
