Answer:
1.9 degrees per second
Step-by-step explanation:
The angle α the line makes with the water can be described by ...
Sin = Opposite/Hypotenuse
sin(α) = 10/(25 -1.9t)
Taking derivatives gives ...
α'·cos(α) = -10(-1.9)/(25 -1.9t)²
Then the rate of change of the angle at t=0 is ...
α' = 19/(25²·cos(α))
Of course, cos(α) = √(1 -sin(α)²) = √(1 -(10/25)²) = √(21/25), so we have ...
α' = 19/(125√21) . . . radians/second
α' ≈ 0.033269 radians/s ≈ 1.90 degrees/s
Answer:
Step-by-step explanation:
so what you would do in order to solve this equation is do inverse operations. what you do to one side of teh equal sign you have to do to the other. so you divide 3/7n by 3/7 which would isolate n. then you would do teh same thing to the 27. 27/ 3/7= 63
n=63
