Answer:

23.89x10^{6} ft

Step-by-step explanation:

\frac{V^{2} }{R^{2} } = \frac{2g}{R+h} \\ 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.

R^{2}(R+h) \frac{V^{2} }{R^{2} } =R^{2} (R+h)\frac{2g}{R+h}   (Multiplying to clear the fractions)

(R+h)V^{2} =R^{2} 2g

R+h=\frac{2R^{2}g }{V^{2} }

h= \frac{2R^{2} g}{V^{2} } -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

How are determinants used to find areas of polygons?
ANTONII [103]
When you arrange the N points in sequence around the polygon (clockwise or counterclockwise), the area is half the magnitude of the sum of the determinants of the points taken pairwise. The N determinants will also include the one involving the last point and the first one.

For example, consider the vertices of a triangle: (1,1), (2,3), (3,-1). Its area can be computed as
  (1/2)*|(1*3-1*2) +(2*-1-3*3) +(3*1-(-1)*1)|
  = (1/2)*|1 -11 +4| = 3
