<span>gravitational potential energy : P
Gravity : g
Mass : m
height : h
P = mgh = 3 x 9.8 x 0.45 = 13.23 Joule
Potential energy is work , from the known formula
W = Fd ( work = force x distance )
W = P ( in case of potential energy height change)
F is the force acting on the body in case of ideal ramp , the only force acting is the weight of the body
F = mg ( not just <m> as the force is mg (Newton) gravity effect)
d is the displacement in direction of force, as we have considered the force to be the weight not it's component in direction of the ramp , the change in displacement is the change in height so
d = h
W = Fd = (F = mg) x (d = h) = mgh
W = mgh = P

The third option should be correct
Answer:
B.) Beachside Sqaure
Step-by-step explanation:
The reason why is because, you have to look at her intentions and the time frame she wants to wait for food at these restaurants. Beachside Sqaure has less times they have made her wait for her food more than 10 minutes, so that would be their advantage.
Answer:
Step-by-step explanation:
The vertex form of a parabola f(x) = ax² + bx + c:
(h, k) - vertex
We have the equation:
Finally:
Answer:
Part a) The expression is
Part b) Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00
Step-by-step explanation:
<u><em>The complete question is</em></u>
A spice store charged 2.75 for 25 grams of paprika. It also charges 5% of the purchase price for shipping any order.
Part a) Write and simplify an expression to determine the cost of buying and shipping x ounces of paprika. Use 1 ounce = 28 grams
Part b) Can a customer buy 2.5 ounces of paprika and have it shipped for less than 8.00? Explain
step 1
Convert grams to ounces
Remember that
To convert grams to ounces divide by 28
The unit price is
Let
x ----> the number of ounces of paprika
y ----> the cost of buying and shipping x ounces of paprika
5%=5/100=0.05
Part b) For x=2.5 oz
substitute in the equation
therefore
Customer cannot buy 2.5 ounces of paprika and have it shipped for less than $8.00
