Answer:
The energy in object is 3.8 Kilo Joules.
Step-by-step explanation:
We are given the following in the question:
Mass = 20 kg
Height,h = 20 m
g=9.5 m/s^2
Formula:
Potential energy =
Putting value we get,
Thus, the energy in object is 3.8 Kilo Joules.

Step-by-step explanation:
Answer:
y = 1/3x + 10/3
Step-by-step explanation:
Slope: 1/3
Point (-4,2)
b = 2 - (1/3)(-4) = 10/3
Answer:
x=-4 x=2
Step-by-step explanation:
y = x^2 + 2x - 8
Set equal to zero
0 = x^2 + 2x - 8
Factor
What two numbers multiply to -8 and add to 2
4 * -2 = -8
4+-2 = 2
0=(x+4) ( x-2)
Using the zero product property
x+4 =0 x-2 =0
x=-4 x=2
For the first day we have the following function:
f (n) = (0.3 * 10) n + 8
For the second day we have the following function:
f (n) = (0.4 * 10) n + 5
You spent the same amount of money as the day before:
(0.3 * 10) n + 8 = (0.4 * 10) n + 5
3n + 8 = 4n + 5
n = 8-5
n = 3 items
We evaluate each function for n = 3
f (3) = (0.3 * 10) * 3 + 8 = 17 $
f (3) = (0.4 * 10) * 3 + 5 = 17 $
The total amount of money is:
17 + 17 = 34 $
Answer:
you purchase 6 items
you spend at the craft store during the sale $ 34
