Two satellites are orbiting Earth. The path of one satellite has the equation x^2 + y^2 = 56250000. The orbit of the other satel

ExtremeBDS [4]

Answer:

1,257 km

Step-by-step explanation:

The path of one satellite has the equation

$x^2 + y^2 = 56,250,000\\ \\x^2+y^2=7,500^2$

This is the equation of the circle with the center at the origin (Eartg) and the radius of 7,500 km.

The orbit of the other satellite is 200 km farther from the centre of Earth, so the radius of this orbit is 7,700 km.

Find the distances travelled by two satellites:

1st satellite:

$D_1=2\pi r_1=2\pi \cdot 7,500=15,000\pi \ km$

2nd satellite:

$D_2=2\pi r_2=2\pi \cdot 7,700=15,400\pi \ km$

Difference:

$D_2-D_1=15,400\pi -15,000\pi =400\pi \approx 1,257\ km$

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function =ht−64t16t2. What is the ma

ryzh [129]

This is the concept of applications of polynomial equations. Given that the height of the ball is modeled by the function:
h(t)=16t^2-64t
the maximum height will be calculated as follows;
h(t)=16t(t-4)
therefore:
t=0 or t=4
h(4)=-64(4)+16(4^2)
=0
