Answer:
A) h=0.5x+7
Step-by-step explanation:
given
initial height = 7 feet
growth rate = 6 in = 0.5 feet / year
let # of growing years = x
For a linear growth rate:
height after x years, h = initial height + (# of growing years) * (growth rate)
substiuting the values above into this equation
h = 7 feet + (x years) * (0.5 feet/year)
or
h = 7 + 0.5x (rearranging)
h = 0.5x + 7
The correct answer is alone! :)
2610 L of water would be needed every day.
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:
200,000
Step-by-step explanation:
Step one:
given data
We are given that 15% of a non-profits Donations is about 30,000
Required
The amount in total received in donation
Step two:
Let the total donation be x
so
15/100*x= 30000
solve for x
0.15*x= 30000
divide both sides by 0.15
x= 30000/0.15
x=200,000
Hence the total donation is about 200000
