Answer:
1.25 seconds
Step-by-step explanation:
Cosine is a maximum at cos(0) = 1, and a minimum at cos(π) = -1.
At the maximum:
8π/5 t = 0
t = 0
At the minimum:
8π/5 t = π
t = 5/8
t = 0.625
The time from maximum to minimum is 0.625 seconds. Therefore, the time from minimum back to maximum is also 0.625 seconds. So the total time is:
0.625 + 0.625 = 1.25
Answer:
The distance of Satelite from the earth's surface = 2720.12 miles
Step-by-step explanation:
Below is the calculation for distance:
Use Pythagorean theorem
Distance, d² = 5400² + 4000²
d² = 45160000
d = 6720.12
Subtract the radius to find the distance from earth's surface.
Distance = 6720.12 - 4000 = 2720.12
The distance of Satelite from the earth's surface = 2720.12 miles
Answer:
5
Step-by-step explanation:
f(x) = |x – 2|
f(3) = |-3 - 2| = |-5| = 5
Answer:
I don't know if you want the beginning to so-
Variable - A unknown value represented by a set letter.
4x+6 = 26
(Incase: Subtract 6 from 6, and 6 from 26. 6 cancels out, and 26-6 is 20. Divide both sides by 4. And x=5)
And the answer to the question is: -27 is the smallest, and then the 3 consecutive numbers are -27, -28, and -29.
