For each of the following determine the 1-unit growth factor.
The 1-unit percent change is -56.25%.
Please help explain so I can figure one out and do the rest on my own. Thanks!
A 1-unit growth factor with a -56.25% change means the quantity decreases by 43.75% when it decreases by 1 unit, resulting in a factor of 0.4375.
The 1-unit growth factor represents the factor by which a quantity changes when it increases by 1 unit.
A 1-unit percent change of -56.25%. A negative percent change indicates a decrease rather than an increase.
To find the 1-unit growth factor when the percent change is -56.25%,
use the formula:
Growth Factor = Final value / Initial value
let's assume the initial value is "I" and the final value is "F."
The percent change of -56.25% means that the final value is 56.25% less than the initial value, or 43.75% of the initial value remains:
F = I - 0.5625I
= 0.4375I
Now, calculate the growth factor:
Growth Factor
= Final value / Initial value
= F /I
= 0.4375I /I
=0.4375
Therefore, the 1-unit growth factor when the percent change is -56.25% is 0.4375, which indicates a decrease of 43.75% when the quantity decreases by 1 unit.

A drawbridge in Jacksonville, FL, allows an average of 22 boats per day to pass. What does the point (4,88) on the graph mean in this situation?
Answer: This shows, 'After 4 days, 88 boats will have passed under the bridge'.
Explanation:
Since, According to the question, Jacksonville allows an average of 22 boats per day to pass.
Thus we can say that number of boats is dependent on days and both are varying.
And, a function is the type of y=f(x), where x is independent variable while y is dependent variable.
So, we can take x for representing number of days and y for representing number of boats.
Thus, according to the question, y= 22x.
if we take 4 days i.e. x=4 then y=22×4=88
⇒It takes 4 days for an average of 88 boats.
Which is showing by (4,88) on the given graph.

What is the product of (–0.9)(–2.4)?
–3.3
–2.16
2.16
3.3
Two negatives terms multiplied together make a positive, so the product of (–0.9)(–2.4) will be equal to 2.16
What is the fundamental principle of multiplication?If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE know that Two negatives multiplied together make a positive, so the two negatives would cancel each other out when multiplying. This would basically make the solution.
WE have to find the product of (–0.9)(–2.4)
it’s simply (–0.9) x (–2.4) = 2.16
Now from the first option 3.3 is definitely not less than 2.4, so the answer would be positive 2.16
Hence, the product of (–0.9)(–2.4) will be equal to 2.16

what is the area of this
The total area of the figure, calculated by summing the areas of three rectangles, is 81 square yards.
The figure in the image is composed of three rectangles. To find the total area, we calculate the area of each rectangle and then sum them up.
The first rectangle has a length of 13 yards and a width of 5 yards. Using the formula for the area of a rectangle, which is length times width, we get an area of 13 yd * 5 yd = 65 square yards.
The second rectangle extends upwards with a length of 2 yards and a width of 5 yards. Its area is 2 yd * 5 yd = 10 square yards.
The third rectangle extends to the right with dimensions of 2 yd by 3 yd. Its area is 2 yd * 3 yd = 6 square yards.
Adding these areas together, we get a total area of 65 sq yd + 10 sq yd + 6 sq yd = 81 square yards.
The question probable may be:
Find the area of the figure. (sides meet at right angles.)
The area of the piecewise rectangular figure is 59 square yards.
How the area is determined:
The first rectangle:
Length = 13 yards
Width = 5 yards
Area of the first rectangle = 65 square yards (13 x 5)
The second rectangle:
Length = 13 yards
Width = 2 yards
Area of the second rectangle = 6 square yards (3 x 2)
Since the second rectangle reduces the first rectangle, we subtract:
Area of the piecewise rectangle = 59 square yards (65 - 6)
Thus, we can conclude that the area of the piecewise rectangular figure is 59 square yards.

Step-by-step explanation:
You own a hamburger franchise and are planning to shut down operations for the day, but you are left with 15 buns, 21 defrosted beef patties, and 17 opened cheese slices. Rather than throw them out, you decide to use them to make burgers that you will sell at a discount. Plain burgers each require 1 beef patty and 1 bun, double cheeseburgers each require 2 beef patties, 1 bun, and 2 slices of cheese, while regular cheeseburgers each require 1 beef patty, 1 bun, and 1 slice of cheese. How many of each should you make? plain burgers:______ double cheeseburgers:_______ regular cheeseburgers:_______
Final answer:
To use the ingredients efficiently, the franchise should make 4 plain burgers, 8 double cheeseburgers, and 1 regular cheeseburger, effectively utilizing all available buns, beef patties, and cheese slices.
Explanation:
To solve the problem of how many plain burgers, double cheeseburgers, and regular cheeseburgers you should make, you need to consider the ingredients as your limiting factors. Starting with the resources available: 15 buns, 21 beef patties, and 17 cheese slices. The recipes are as follows: plain burgers require 1 beef patty and 1 bun; double cheeseburgers require 2 beef patties, 2 cheese slices, and 1 bun; regular cheeseburgers require 1 beef patty, 1 cheese slice, and 1 bun.
First, notice that the number of buns is the overall limiting factor for the maximum number of burgers you can make, which is 15.Second, consider maximizing the use of cheese slices by making as many double cheeseburgers as possible, which would be 8 (consuming 16 beef patties and 16 cheese slices, leaving 5 buns, 5 beef patties, and 1 cheese slice).With the leftovers, you can make 1 regular cheeseburger (using 1 more beef patty, 1 cheese slice, and 1 bun) and then 4 plain burgers with the remaining 4 beef patties and buns.Therefore, you should make 4 plain burgers, 8 double cheeseburgers, and 1 regular cheeseburger to utilize the ingredients efficiently without waste.

find (f*f)(3) f(x)=x^2-x
To find (f * f)(3) for the function f(x) = x² - x, we calculate f(3) to get 6, and then square it to get 36.
The question is asking to calculate (f * f)(3) given the function f(x) = x² - x. To do this, we find the value of f(x) for x=3 and then square that result. First, let's compute f(3).
f(3) = (3)² - (3) = 9 - 3 = 6.
Now, we find (f * f)(3), which means f(3) * f(3).
(f * f)(3) = f(3) * f(3) = 6 * 6 = 36.
Therefore, the solution to (f * f)(3) is 36.
