Answer:
Step-by-step explanation:
1. Angular speed
The angular speed ω is the angle θ swept out by the satellite in a given time t.
2. Linear speed
The formula for the linear speed v is
v = rω, where
r = the distance from the centre of the Earth = 6378 km + 1250 km = 7628 km
Answer:
D. (1,0)
Step-by-step explanation:
Just plug in each coordinate for x and y into 4x+2y and see which one is less than or equal to 6.
Lets go through all of the possible answers:
<u>A</u>. (0,4)
4(0) + 2(4) ≤ 6
0 + 8 ≤ 6
8 ≤ 6
This is false. 8 is not less than or equal to 6.
<u>B</u>. (5,0)
4(5) + 2(0) ≤ 6
20 + 0 ≤ 6
20 ≤ 6
This is false. 20 is not less than or equal to 6.
<u>C</u>. (5,7)
4(5) + 2(7) ≤ 6
20 + 14 ≤ 6
34 ≤ 6
This is false because 35 is not less than or equal to 6
<u>D</u>. (1,0)
4(1) + 2(0) ≤ 6
4 + 0 ≤ 6
4 ≤ 6
This is true, because 4 is less than 6.
Solve for x over the real numbers:x^3 = 1/27
Hint: | Eliminate the power on the left-hand side.Take cube roots of both sides:Answer: x = 1/3
