The ball will hit the ground when h(t)=0 so:
-16t^2+10t+100=0
Using the quadratic equation:
t=(-10±√6500)/-32, and since t>0
t≈2.8 seconds (to nearest tenth of a second)
The formula is right there, Mr. President.
All you need to do is write the numbers you know into the correct
places in the formula, and then find the value of the fraction.
The formula: Density = (mass) / (volume)
You know:
mass = 67.5 grams
volume = 5 ml
Write them in the correct places in the formula:
Density = (67.5 grams) / (5 ml)
= (67.5 / 5) (grams / ml)
= 13.5 grams/ml
-7x+y=23
6x+7y=-4
y=7x+23
6x+7(7x+23)=-4
6x+49x+161=-4
55x+161-161=-4-161
55x/55=-165/55
x=-3
-7(-3)+y=23
21+y-21=23-21
y=2
