Find each side of the triangle if the perimeter is 46
2x + 6
2(x – 4)
x + 3
Answer:
s+s+s =p
2x+6+2(x-4)+x+3=p
2x+ 6 + 2x-8+x+3=p
6-x-3=4x+12 solve for x

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
19/3

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

Step-by-step explanation:
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.
