Answer: answer is d
Step-by-step explanation: input in calculator or set both equal to y and then set them equal to each other
Using Pythagoras theorem, the top of the ladder moving down when the foot of the ladder is 3 feet from the wall is of -0.518 feet/sec.
Let distance from the wall to the foot of the ladder is 'x' feet and the height of the top of the ladder is 'y' feet.
Pythagoras theorem,
--->(1)
Given,
at x=3
Put x=3 in Pythagoras theorem equation (1)


= 135
y = 11.61
Derive equation (1) w.r.t to 't'
---->(2)
substitute the value of 'x', 'dx/dt' and 'y' in equation (2), we get the fast of the top of the ladder moving down when the foot of the ladder is 3 feet from the wall
12 + 23.22
= 0


Hence, using Pythagoras theorem the top of the ladder moving down when the foot of the ladder is 3 feet from the wall is of -0.518 feet/sec.

A) How long did it take for Jason to reach his maximum height? -b/2a=-16/-32= 1/2s
B) What was the highest point that Jason reached?
484ft ~h(ois)
C) Jason hit the water after how many seconds?
roots -5&6 so 6s
Oh and by the way there is some seriously cool cliff jumps in Acapulco, I'm dying to go.
<u>1/2s, 484ft, 6s</u>
Answer:
197 is the missing side of the triangle
If the side of the square is a it becomes 1.2a after the increase and its area becomes 1.44a². So the increase is 1.44-1=0.44 or 44%.
