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]

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

The length of each side of an equilateral triangle is increased by 5 inches, so the perimeter is now 60 inches. Write and solve

AfilCa [17]

Answer:

The original length of each side of the equilateral triangle = x =15 inches

Step-by-step explanation:

Let Original length of side of equilateral triangle = x

If it is increased by 5 inches, the length will become = x+5

Since in equilateral triangle all the ides have same length so,

New Length of side 1 = x+5

New of side 2 = x+5

New Length of side 3 = x+5

Perimeter of triangle = 60 inches

We need to find the value of x

The formula used is: $Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3$

Putting values in formula and finding x

$Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3\\60=x+5+x+5+x+5\\60=3x+15\\60-15=3x\\45=3x\\x=\frac{45}{3}\\x=15$

So, the original length of each side of the equilateral triangle = x =15 inches
