Need help with this question! Will attach pic! A satellite is to be put into an elliptical orbit around a moon as shown below.Th
Darina [25.2K]
An equation for the ellipse ( standard form ):
x²/a²  +  y²/b² = 1
Here is:  a - semi-major axis and b - semi-minor axis.
Radius of the moon is 1,000 km and the distance from the surface of the moon to the satellite varies from 953 km to 466 km.
a = 1,000 + 953 = 1,953 km
b = 1,000 + 466 = 1,466 km
Answer:
The equation is  x² / 1,953²  + y² / 1,466² = 1
or: x²/3,814,209  +   y²/2,149,156  = 1

Vilka [71]
Primary equation: A(x)= (5y)(3X)
Secondary equation: 5y+3X=1000
y=200-(3X)/5
A(x)=3X(1000-3X)
A(x)=3000X-9X²

Now, find the derivative of A(x) to find the max... here's the work for that, or you could guess and check.

A'(x)=3000-18X

Set derivative equal to 0

0=3000-18X
166.6666666=X

Now test the intervals

(0,166.6666) (166.66666, 1000)
1st derivative is + 1st derivative is -

Plug the X value back into the secondary equation
5y+3(166.666666)=1000
5Y=500
Y=5

Answer:
X= 166.6666666666
Y=5

Please note, this is entry level calculus, and your teacher may expect you to use a different, longer route such as guess and check.

Question 2 Multiple Choice Worth 1 points)
Tomtit [17]

Answer: "Subtract 6 from both sides, and then divide by 2. The solution is x = 8"

Step-by-step explanation: Lets solve for 2x + 6 = 22

Step 1 Subtract 6 from both sides: 2x + 6 - 6 = 22 - 6                       2x = 16

Step 2 Divide by 2 in both sides: 2x/2 = 16/2

Step 3 The answer: x = 8
