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.
For number 9. its 34 × 65 = 65 × 34.. So that means its communicative property
<h3>Given :</h3>
<h3>To Find :</h3>
<h3>Solution :</h3>
As, f(x) = 2x - 3
Therefore, f(-2) = 2(-2) - 3
<h3>Hence, value of f(-2) is - 7.</h3>
Multiply each exponent inside the parentheses by the exponent on the outside of the parentheses:
4/5 x 3 = 12/5
9 x 3 = 27
Answer : m^12/5n^27
