A fish is reeled in at a rate of 1.9 feet per second from a point 10 feet above the water (see figure). At what rate is the angl
DENIUS [597]

9514 1404 393

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

Explain how you can determine the initial value of a linear relationship, the y- intercept, when given two points.
Paladinen [302]
There is a formula to find the slope (m)

(y2 - y1) / (x2 - x1)

So we now have y = mx + b where m is the value you just calculated

The y intercept (b) = y - mx

Plug in the x,y values for one of your points into this formula
