A state tourist guide provides information on summer vacation towns. Some of the towns and related information are given in the
table below.
A 5-column table with 4 rows. Column 1 is labeled Town with entries Spring Haven, Prineville, Juniper Lake, Crestview. Column 2 is labeled Average Temp (degrees Fahrenheit) with entries 73.2, 75.1, 70.3, 68.7. Column 3 is labeled Number of Hotels with entries 12, 15, 4, 18. Column 4 is labeled Beach access question mark with entries yes, no, yes, no. Column 5 is labeled location with entries west, north, west, south.
What are the individuals in the data set?
towns
average temperatures
beach access

Answer:
Step-by-step explanation:
In order to find the horizontal distance the ball travels, we need to know first how long it took to hit the ground. We will find that time in the y-dimension, and then use that time in the x-dimension, which is the dimension in question when we talk about horizontal distance. Here's what we know in the y-dimension:
a = -32 ft/s/s
v₀ = 0 (since the ball is being thrown straight out the window, the angle is 0 degrees, which translates to no upwards velocity at all)
Δx = -15 feet (negative because the ball lands 15 feet below the point from which it drops)
t = ?? sec.
The equation we will use is the one for displacement:
Δx = and filling in:
which simplifies down to
so
so
t = .968 sec (That is not the correct number of sig fig's but if I use the correct number, the answer doesn't come out to be one of the choices given. So I deviate from the rules a bit here out of necessity.)
Now we use that time in the x-dimension. Here's what we know in that dimension specifically:
a = 0 (acceleration in this dimension is always 0)
v₀ = 80 ft/sec
t = .968 sec
Δx = ?? feet
We use the equation for displacement again, and filling in what we know in this dimension:
Δx = and of course the portion of that after the plus sign goes to 0, leaving us with simply:
Δx = (80)(.968)
Δx = 77.46 feet
