Calculate f(x) for all numbers between 0 and 10:
f(0) = −0^2 + 11(0) − 18 = -18
f(1) = −1^2 + 11(1) − 18 = -8
f(2) = −2^2 + 11(2) − 18 = 0
f(3) = −3^2 + 11(3) − 18 = 6
f(4) = −4^2 + 11(4) − 18 = 10
f(5) = −5^2 + 11(5) − 18 = 12
f(6) = −6^2 + 11(6) − 18 = 12
f(7) = −7^2 + 11(7) − 18 = 10
f(8) = −8^2 + 11(8) − 18 = 6
f(9) = −9^2 + 11(9) − 18 = 0
f(10) = −10^2 + 11(10) − 18 = -8
When the value is negative it doesn't drip, so it starts and stops dripping when the values = 0
Which is f(2) and f(9), the values are 2 and 9.
Answer: 25 guests is 2.5 times more than 10
Multiply each order by 2.5
Chicken = 16 x 2.5 = 40
Lasagna = 7 x 2.5 = 17.5 , round to 18
Deli meat = 1.8 x 2.5 = 4.5, round to 5
Sliced cheese = 15 x 2.5 = 37.5, round to 38
Buns = 1 x 2.5 = 2.5, round to 3
Potato salad = 2 x 2.5 = 5

Answer:
She drove 384 miles, because 48 x 8 = 384! :)
Step-by-step explanation:
The formula for the volume, V of a cone is V = (1/3)*π*(radius)^2 * height.
So, as you see you have two variables, radius and height, which means that there are different combinations of radius and height that lead to the same volume.
That implies that your questions is missing some information.
I searched for it and found that the question has a list of answer choices. This is the list:
a) radius 6 inches, height 3 inches
b) diameter 6 inches, height 3 inches
c) diameter 4 inches, height 6 inches
d) diameter 6 inches, height 6 inches
Now you can probe those options to see which leads to an approximate volume of 28 cubic inches.
a) radius 6 in, height 3 in
=> V = (1/3)*3.14*(6in)^2 * 3in = 113.04 in^3 => not possible
b) diameter 6 in, height 3 incdiameter 6 in => radius 3 in=> V = (1/3)*3.14*(3in)^2 * 3in = 28.26 in^3 => this is the answerThe other options lead to values far from 28 in^3.Answer: diameter 6 inches, height 3 inches.
