Answer:
Her potential energy is approximately 4481 J.
Step-by-step explanation:
Because the formula for potential energy is PEg = 9.81 * mass * height, just plug in the knowns. After you plug those in, you will get the potential energy as 9.81 * 450, which is approximately 4481 J.
Answer:
30%
Step-by-step explanation:
2000-----100%
1400------x%
x=(1400×100)÷2000
X=70%
final we go 100%-70%=30%
Television price reduced for 30%
<u>Multiply the whole number by the denominator. Add the product to the numerator of the proper fraction. The sum is the numerator of the improper fraction. The denominator will stay the same.</u>
F(x) = 2x-8
so when x=4 replace x with 4 to get 2(4)-8 which equals 8-8 = 0
so f(4) = 0
and from the table when the input (x) is 4, the output (y) is 9
9 is greater than 0 , so the table has a greater value when x = 4
