Watching a Helicopter Take Off At a distance of 58 ft from the pad, a man observes a helicopter taking off from a heliport. If the helicopter lifts off vertically and is rising at a speed of 55 ft/sec when it is at an altitude of 113 ft, how fast is the distance between the helicopter and the man changing at that instant? (Round your answer to one decimal place.)
The Pythagora´s Theorem, tell us that in a right triangle, the square of the hypothenuse (L²) is equal to :
L² = x² + y²
x and y are the legs.
The solution is
dy/dt = 48.9 ft/s
We know that in a right triangle:
L² = x² + y² (1)
If the helicopter lifts off vertically, that means x ( the horizontal distance between the observing man and the helicopter, maintains constant).
According to that, if we get derivatives with respect to time on both sides of equation (1) we get:
2×L× dL/dt = 0 + 2×y×dy/dt (2)
And
L = √ ( 58)² + ( 113)² = √12769 + 3364 = 127.02 ft
L = 127.02 ft when y = 113 ft
Now in equation (2) we know:
y = 113 ft dy/dt = 55 ft/s L = 127.02 we look for dL/dt
Then by substitution
2×127.02 × dL/dt = 2×113×55
254.04× dL/dt = 12430
dL/dt = 48.92
dL/dt = 48.9 ft/s

Answer: The equation has infinitely many solutions.
Step-by-step explanation:
With George's end result of 3=3, you can assume that the equation is set up in such a way that no matter what you plug in, you will get the same number on both sides of the equals sign, which means the solution is valid. Therefore this means that there are an infinite number of solutions.

what is 0.95 as a simplified fraction?
Answer:
19/20
Step-by-step explanation:
A "simplified fraction" in this case is the ratio of two integers.
0.95 = 95/100 (the ratio of two integers), which in turn can be simplified:
95/100 = 19/20

Answer:
y = -5/3x + 19/3
Step-by-step explanation:
y2 - y1 / x2 - x1
-2 - 8 / 5 - (-1)
-10/6
= -5/3
y = -5/3x + b
8 = -5/3(-1) + b
8 = 5/3 + b

What is an equation of the line that passes through the point (-8, -1) and is
parallel to the line x – 4y = 4?
Answer:
y = 1/4x + 1
Step-by-step explanation:
x - 4y = 4
x - 4 = 4y
1/4x - 4/4 = y
1/4x -1 = y
Slope: 1/4
Point: (-8,-1)
y-intercept = -1 - (1/4)(-8)=
-1 + 2 = 1

PROBLEM SOLVING A water sample must be taken from water at least 20 feet deep. Find the depth of the water 50 feet
from shore.
50 ft
5 ft
21.5t
d
Not drawn to scale
The depth is
feet.
Is this an appropriate location for a water sample?
Using the principle of similar triangles, the appropriate depth to take the water sample should be 15 feets
Setting up the equation thus :
1.5 / d = 5 / 50
Cross multiply
1.5 × 50 = d × 5
75 = 5d
Divide both sides by 5
5d / 5 = 75/5
d = 15
Therefore, the appropriate depth to take the water sample is 15 feets.

Answer:
there is no real solution
Step-by-step explanation:
There is no number that, when squared, produces a negative value. A negative multiplied by a negative gives a positive, and a positive times a positive gives a positive. You can however have a ± symbol to indicate that the root of 36 could be either positive or negative
