h = -16t^2+ Vt
Given V = 30 fps
When ball hit the ground, h = 0
-16t^2+30t = 0
16t^2 = 30t
16t = 30
t = 30/16
t = 15/8 sec
The answer is 6.30 seconds, you can find this by graphing the equation. you can use desmos for help graphing digitally if you have to.
Cost of 7 gallons=$24.50
Cost of 1 gallon=24.50/7=3.5
Cost of 15 gallons=15*3.5=52.5
Cost of 15 gallons will be $52.5
The total nom of code that can be used is equal to 5+3 = 8
The answer is in the image
For every 8 cars there are 7 trucks
Therefore,
Cars:Truck=8:7
Answer is B)8:7
The solution is in the following image
y=2x+15
where y=Value of coin
x=Age in years
Value of coin after 19 years=2*19+15
=$53
Therefore, Value after 19 years=$53
F=ma
where F=force
m=mass
a=acceleration
Here,
F=4300
a=3.3m/s2
m=F/a
=4300/3.3
=1303.03kg
Approximately it is aqual to 1300kg
The solution is given in the image below
