Answer:
Step-by-step explanation:
To understand the situations we must do a Venn diagram:
The total of people asked is 3400. Then,
a) For People who enjoyed vanilla but not chocolate or mint, seeing the diagram of Venn, we can deduce the equations:

b) For people who did not enjoy chocolate, vanilla or mint:
First you'd work around the parenthesis, getting you a reduced problem of -2x-6-5.
combine like terms to receive -2x-11
now treat the f(x) as Y and you'll get y=-2x-11; toss it onto a graph and plot the individual points (your answer options)
all points except for A do not touch the line, resulting in your answer to be letter A!
hope this helps :)
Answer:
1020?
Step-by-step explanation:
im not sure completely but the formula for volume is length x width x height
The function is symmetric in the line that goes trough the top. The top is on t=2.5 seconds. If you want to know on which time the height is equal to 15 feet, you draw a line on that height in the graph and see where it crosses. That is at t=1.25 and t=3.75
