No this is not a function because 4 is used twice on the y side
The independent variable is the cost of the skateboard, c.
The dependent variable would be the total cost, t.
The best way to understand this is that the cost of the skateboard from the company is not going to change based on a sales tax rate., But the overall total cost could change depending on what the sales tax rates are.
The total cost would be dependent upon the sales tax rate.
Answer:
DE = 4 1/2
EF = 3 3/4
Step-by-step explanation:
AB/AC = DE/DF
6/4 = DE/3
cross-multiply:
4DE = 18
DE = 18/4 or 4 1/2
AB/BC = DE/EF
6/5 = 4.5/EF
cross-multiply:
6EF = 22.5
EF = 3.75
Answer:
On the way up, 1.8 seconds and on the way down 4.1 seconds.
Step-by-step explanation:
Use the motion under gravity equation s = ut + 0.5gt^2 where u = initial velocity, s = the height, t = time and g = acceleration due to gravity ( 32 fts-2).
So 120 = 95t + 0.5(-32)t^2
-16t^2 + 95t - 120 = 0
Solving this using the quadratic formula:
t = [-95 +/- √(95^2 - 4 * -16*-120)] / -32
t = 1.823, 4.1148.
The first value refers to the upward journey and the second to the downward journey.
