The possible functions are
A. F(x)=2x^2-8x-42
B. F(x)=5x^2+20x-105
C. F(x)=x^2+4x-21
How to determine the possible equations?The zeros are given as:
x = -7 and x = 3
Rewrite as:
x +7 = 0 and x - 3 = 0
Multiply both zeros
(x + 7) * (x - 3) = 0 * 0
Evaluate the product
x^2 + 7x - 3x - 21 = 0
Evaluate the like terms
x^2 + 4x - 21 = 0
Express as a function
f(x) = a(x^2 + 4x - 21)
Where a is a constant
Let a = 1, 2 and 5 (according to the values in the options)
f(x) = 1 * (x^2 + 4x - 21) = x^2 + 4x - 21 --- option (c)
f(x) = 2 * (x^2 + 4x - 21) = 2x^2 + 8x - 42 --- option (a)
f(x) = 5 * (x^2 + 4x - 21) = 5x^2 + 20x - 105 --- option (b)
Hence, the possible functions are (a), (b) and (c)

A restaurant owner wants feedback on the items on the menu, so she leaves a customer satisfaction survey on the tables for customers to
complete if they wish. Which sampling method best describes this scenario?
O A) convenience sample
OB) simple random sample
O C) stratified random sample
OD) voluntary response sample
Answer:
O A) convenience sample
Step-by-step explanation:
O A) convenience sample
The sampling method which describes the situation is option D. voluntary response sample.
What are Sampling Methods?Sampling methods are methods used to select a sample using specific methods. This includes various types of probability sampling and non probability sampling methods.
This is included in the non probability sampling methods.
So it is either convenience sample or voluntary response sample.
Convenience sample is the selection of a sample which is convenient for you. That is, the sample which is most accessible is selected by the researcher.
Voluntary response sample is also the one which is most accessible. But the researcher is not selecting the sample. Instead the members of the population can decide whether to took part in the sample.
Here it is customer's wish to complete the survey.
So it is voluntary response sample.
Hence the correct option is D. voluntary response sample.

[tex]a =\sqrt{c^{2} - {b^{2 } \\[/tex]
[tex]a = \sqrt{1700^2 - 1300^2}[/tex]
[tex]a = \sqrt{2890000 - 1690000}[/tex]

A watering can contained 512 quarts water. After all the plants were watered, only 4 cups remained. How many cups of water were used to water the plants?
Answer:
2044 cups
Step-by-step explanation:
number of cups left = number of cups in the watering can - number of cups remaining
convert the capacity of the watering can to cups
1 quart = 4 cups
512 x 4 = 2048
2048 - 4 = 2044
Question 9 (1 point)
Find the volume of the composite shape below.
5ft - 2 ft
Leave in terms of pi. Round to the nearest whole number!
Volume=
Tft?
Blank 1:
Question 101
30.66pi ft³
First, we need to find the volume of the cylinder using the following equation
[tex]V = r^2h\pi \\V = (2^2)5\pi \\V = (4)5\pi \\V = 20\pi[/tex]
The volume of the cylinder is 20pi
Next, we need to find the volume of a sphere. Since the cylinder is divided in half by the cylinder, we can use the following equation as if it were whole
[tex]V = \frac{4}{3} r^3\pi \\V = \frac{4}{3} 2^3\pi \\V = \frac{4}{3} 8\pi \\V = 10\frac{2}{3} \pi[/tex]
The volume of both half spheres is 10.66pi
Now we can add both together to get 30.66pi ft³
