Answer:
Step-by-step explanation:
The equation that models the height of the ball in feet as a function of time is

Where
is the initial height,
is the initial velocity and t is the time in seconds.
We know that the initial height is:
The initial speed is:

So the equation is:

The ball hits the ground when when
So

We use the quadratic formula to solve the equation for t
For a quadratic equation of the form

The quadratic formula is:

In this case

Therefore

We take the positive solution.
Finally the ball takes 2.47 seconds to touch the ground
'Parallel' means parallel TO something else. A single line all by itself
is not "a parallel line", until we know the other line that it's parallel TO.
There are an infinite number of lines that pass through (0, -2).
Give us another line, and we'll find the one that's parallel to it.
Answer:
You count something
Step-by-step explanation:
If you imagine 9 slots that are empty and you fill 3 of them then there is 6 empty slots so -6
Answer:
a = 180 - b - c
Step-by-step explanation:
given 180 = a + b + c or
a + b + c = 180 ( isolate a by subtracting b from both sides then c )
subtract b from both sides
a + c = 180 - b
subtract c from both sides
a = 180 - b - c
Answer:
Divide 50,000 by 8.4...get that number and add it to the 50,000, divide again by 8.4 and add back, repeat until you reach 1,000,000... happy adding
