Period: π; phase shift: x = π
To solve this we are going to use the free distance fallen formula:
where
is the distance
is the gravity of Earth
is the time in seconds
We know from our problem that the
penny fell off the top of the building and hit the sidewalk below 3.1 seconds later, so
. Lets replace the value in our formula:
meters
We can conclude that the penny fell a distance of 47.098 meters

Your question was how. teehee
Answer:
-8/5
Step-by-step explanation:
The thing that makes lines different from other kinds of curves is their <em>constant rate of change</em>. We call this rate of change <em>slope</em>, and you usually see it represented with the letter <em>m</em>. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.
We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate <em>increases </em>by 5, while our y-coordinate <em>decreases </em>by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as
m = -8/5
80 units
Step-by-step explanation:
Step 1 :
Given,
The function representing the height is y = 4x^2-32x+80
where the x represents the time after they jumped and y represents their height above ground.
We need to find the platform's height.
Step 2 :
Since x represents the time after they jumped, x = 0 when they have not started jumping and the corresponding y will give the height before they start jumping which would be the height of the platform
Step 3:
When x = 0 we have
y = 0-0+80 = 80
So the height of the given platform is 80 units.
