1. h₀ = 70
v₀ = 0 since the rock is dropped it has no initial velocity
when the rock hits the ground the height = 0
plug into the formula
0 = -4.9t² + 0(t) + 70
0 = -4.9t² + 70
Add 4.9t² to both sides
4.9t² = 70
Divide both sides by 4.9
t² = 14.2857142857
Take the square root of both sides
t = 3.7796447301
t ≈ 3.8 seconds
I am not doing the rest I only did one just to help you understand a bit more

Step-by-step explanation:
To determine how many different types of shelves could be ordered, you will multiply all the numbers from each different aspect of the shelves to create all the possible combinations that could occur.
The reason for doing this has to do with the groupings that will occur using all three numbers.
4 x 3 x 6 = 72
There are 72 different possibilities of shelves.
Intercepts can either be an x-intercept or a y-intercept. Both intercepts can be determined by simply setting the other variable to be zero. For instance, to obtain the x-intercept, we must equate the y value of the equation to zero and vice versa.
x-intercept: Setting y=0
y=5x-13
0=5x-13
5x=13
x=13/5
y-intercept: Setting x=0
y=5x-13
y=5(0)-13
y=-13
Therefore, the intercepts are y=-13 and x=13/5 or (0,-13) and (13/5 ,0) in point form.
