Answer:
240 feet
Step-by-step explanation:
Given that,
The object falls 400 feet in 5 seconds.
We need to find how far it fall in 3 seconds.
5 seconds = 400 feet
1 second = 80 feet
So,
In 3 seconds,
d = (80×3) feet
= 240 feet
So, it will fall 240 feet in 3 seconds.
Scotty situation:
So Scotty earns $35 bucks for 5 hours so you’re going to have to find out what he earns for each hour.
35/5=$7 an hour
So to get to $42 in total you divide 42/7 which would give you six.
So it will take Scotty six hours to earn $42.
And 42/14=9/3
Answer:
The process below should work.
Step-by-step explanation:
Let's pretend we have these two points we are trying to find an exponential equation for: (-2,6) and (2,1).
Exponential equations are of the form
where we must find
and
.
So you enter both points into that equation giving you:


I'm going to divide equation 1 by 2 because if I do the a's will cancel and I could solve or b.


By law of exponent, I can rewrite the right hand side:


Now do ^(-1/4) on both sides to solve for b:

Now we use one of the equations along with our value for b to find a:
with 

Simplify using law of exponents:

Multiply both sides by 6^(1/2) to solve for a:

with
is:

We can simplify a smidgen:

3/k = 4/5
k = 3 divided by 4/5
k = 3.75
