The potential energy is converted into kinetic energy.
Therefore, for conservation of energy we have:
mgh = (1/2) m * v ^ 2
From here we clear the speed:
v = root (2 * g * h)
The height will then be:
h = v ^ 2 / (2 * g)
Substituting the values:
h = (34) ^ 2 / (2 * (32))
h = 18.0625 feet
Answer: The pear before it fell was 18.0625 feet up in the tree.
Answer:
x=55
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees
<A + < B + <C = 180
x + 75+ 50 = 180
x + 125 = 180
subtract 125 from each side
x = 180-125
x = 55
Answer: 125
Step-by-step explanation: The whole triangle equals 180 degrees and you have 2 two sides 25 and 30 so subtract those from 180 and you get 125.
The rate of change is the same as the slope.
Let's find the slope of function 1 using the Rise Over Run rule.
The rise is 2 and run is 1. So your rate of change is 2/1 or 2 for function 1
Function 2 is a y = mx + b equation, the slope is usually "m" or before the x
y = 1/2x + 7
1/2 is your rate of change for function 2
Answer:
the answer is 40
Step-by-step explanation:
A = 10 x 8 over 2 which is 40
