Answer:
n² - 6n - 16
Step-by-step explanation:
As per the question,
We have been provided the equation
(n-8)(n+2)
To find the product, we have to multiply the both term,
(n - 8) (n + 2)
= n (n + 2) - 8 (n + 2)
= (n² + 2n) - (8n + 16)
= n² + 2n - 8n - 16n
= n² - 6n - 16
Hence, the required answer of the product of (n-8)(n+2) = n² - 6n - 16.
= 1/2kx2
U = potential energy of a spring at a certain position
k = the spring constant, specific to the spring, with units N/m.
x = distance the spring is stretched or compressed away from equilibrium
Potential Energy: Elastic Formula Questions:
1) A spring, which has a spring constant k = 7.50 N/m, has been stretched 0.40 m from its equilibrium position. What is the potential energy now stored in the spring?
Answer: The spring has been stretched x = 0.40 m from equilibrium. The potential energy can be found using the formula:
U = 1/2kx2
U = 1/2(7.50 N/m)(0.40 m)2
U = 0.60 N∙m
U = 0.60 J
The mug cost $12 as it is, so first you subtract 12 from 34, which is 22. From there, you divide 22 by 2.20, which would be 10. Therefore, she can get a mug and 10 refills for $34.
