Find the value of x and then the measure of angle WVZ and angle WVY. You should have 3 answers (Hint: 2 of them will be the same

cestrela7 [59]

Answer:

x = 11°

Angle WVZ = Angle XVY = 84°

Step-by-step explanation:

Angle WVZ = Angle XVY

Vertical opposite angles

9x - 15 = 5x + 29

4x = 44

x = 11°

Angle WVZ = Angle XVY = 9(11) - 15

= 99 - 15 = 84°

WVY is probably a typo, but if needed:

Angle WVY is 180° because they form a straight line

the linear combination method is applied to a system of equations as shown.4(.25x .5y = 3.75) → x 2y = 15 (4x – 8y = 12) → x – 2

gtnhenbr [62]

If we use the last equation:
2 x = 18
x = 18 : 2
x = 9
Then we will put it in another equation:
x - 2 y = 3
9 - 2 y = 3
- 2 y = 3 - 9
- 2 y = -6
y = -9 : ( -3 )
y = 3.
The solution is : D ) ( 9, 3 )

A satellite orbits the Earth with an elliptical orbit modeled by x squared over 43 million eight hundred twenty four thousand fo

morpeh [17]

"For a satellite orbit, the Earth with an elliptical orbit modeled by..." the maximum distance between the satellite and the Earth is

D= 510 km. Option B. This is further explained below.

<h3>What is Kepler Orbit?</h3>

Generally, In the study of astrodynamics, an ellipse of the satellite is often referred to as a Kepler Orbit

The function of the elliptical orbit is

$\frac{(x-h)^2}{a^2}+\frac{(x-k)^2}{b^2}=1$

compared to

$\frac{(x^2)^2}{47334400}+\frac{(y^2)^2}{43956900}=1$

Hence

a = √(47,334,400 km²)

a= 6,880 km.

In conclusion, The distance of the satellite above the Earth's surface.

D = a - r

D= 6,880 km - 6,370 km

D= 510 km
