{-6, -3, 1, 14} and {12, -2, 0, -4} respectively.
What is range?We know that the range refers to all possible values of y, and the domain refers to all possible values of x.
How to solve it?For (-6, 12), the x value = -6 and the y value = 12.
For (-3, -2), the x value = -3 and the y value = -2.
For (1, 0), the x value = 1 and the y value = 0.
For (14, -4), the x value = 14 and the y value = -4.
So, the domain is {-6, -3, 1, 14} and the range is {12, -2, 0, -4}.
Therefore the domain and range of the function represented by the set of ordered pairs {(-6, 12).(-3,-2), (1,0), (14,-4)} is

Suppose Charmaine borrows $7500 at an interest rate of 12% compounded each year.
Assume that no payments are made on the loan.
Follow the instructions below. Do not do any rounding.
(a) Find the amount owed at the end of 1 year.
(b) Find the amount owed at the end of 2 years.
AS per the concept of Compound interest,
(a), The amount owed at the end of 1 year is $8,400
(b) The amount owed at the end of 2 year is $ 9,408
Compound interest:
The general formula to calculate the compound interest is
A = P(1 + r/n)ⁿˣ
where
A represents Accrued amount (principal + interest)
P represents Principal amount
r represents Annual nominal interest rate as a decimal
n represents number of compounding periods per unit of time
x = time
Given,
Suppose Charmaine borrows $7500 at an interest rate of 12% compounded each year. Assume that no payments are made on the loan.
Here we need to find the following,
a)the amount owed at the end of 1 year.
b) the amount owed at the end of 2 year.
From the given details we know that the value of
Principal amount = $7,500
Interest rate = 12%
Part a) the amount owed at the end of 1 year is calculated as,
Here we have to convert R as a percent to r as a decimal
r = R/100
r = 12/100
r = 0.12 rate per year,
Then solve the equation for A
A = 7,500.00(1 + 0.12/1)(1)(1)
A = 7,500.00(1 + 0.12)(1)
A = $8,400.00
Therefore, the amount owed at the end of 1 year is $8,400.
Part b) The amount owed at the end of 2 year is calculated as,
In this one the value of principal amount interest rate are same but the value of year only differs as 2,
So, the amount is
=>A = 7,500.00(1 + 0.12/1)(1)(2)
=> A = 7,500.00(1 + 0.12)(2)
=> A = $9,408.00
Therefore, the amount owed at the end of 2 years is $9,408.

For any positive integer n, the value of n! is the product of the first n positive integers. For example, 4! = 4 * 3 * 2 * 1 =24. What is the greatest common divisor of 5! and 7! ?
The GCD of 5! and 7! is 2^3 * 3^1 * 5^1 = 120.
the greatest common divisor of 5! and 7! is 120.
To find the greatest common divisor (GCD) of 5! and 7!, we need to factorize both numbers and identify the common factors.
First, let's calculate the values of 5! and 7!:
5! = 5 * 4 * 3 * 2 * 1 = 120
7! = 7 * 6 * 5 * 4 * 3 * 2 * 1 = 5,040
Now, let's factorize both numbers:
Factorizing 120:
120 = 2^3 * 3 * 5
Factorizing 5,040:
5,040 = 2^4 * 3^2 * 5 * 7
To find the GCD, we need to consider the common factors raised to the lowest power. In this case, the common factors are 2, 3, and 5. The lowest power for 2 is 3 (from 120), the lowest power for 3 is 1 (from 120), and the lowest power for 5 is 1 (from both numbers).

Answer:
Entrance fee for children: $1.92
Entrance fee for adults: $3.92
Step-by-step explanation:
Total expenses for this year: $214.00
The child fee will be: $x
and the adult fee will be $(x+2)
Last year the number of children was 44
and the number of adults was 33
this year also has the same number of children and adults.
which means the entrance fee total for children will be $44x and for adults will be $33(x+2).
44x + 33(x+2) = 214
--> 44x + 33x + 66 = 214
--> 77x = 214 - 66 = 148
--> x = 148/77 = 1.92
So children's price is $1.92 and adults price is $1.92 + 2
hence:
Entrance fee for children: $1.92
Entrance fee for adults: $3.92

One meter of shielded microphone cable weighs 75/1,000 kilogram. What is the length of cable in coil that weigh 5 1/2 kilogram
The length of cable in the coil that weighs 5 1/2 kilograms is 1/2 meter.
Let x be the length of cable in meters that weighs 5 1/2 kilograms.
Then, we can write:
1 meter / (75/1000) kilograms = x meters / 5.5 kilograms
Simplifying the left side, we get:
1 meter / (75/1000) kilograms = 1000 / 75 meters/kilogram
= 40/3 meters/kilogram
Substituting this into our proportion, we get:
40/3 meters/kilogram * x meters = 5.5 kilograms
Multiplying both sides by 3/40, we get:
x meters = (5.5 kilograms) * (3/40) * (40/3 meters/kilogram)
= 1/2 meter
The length is 1/2 meter

Answer:
f(g(0)) = -2
Step-by-step explanation:
We have our two equations, f(x) and g(x).
We work our way from the inside to the outside. Our inside equation is g(0). If we match g(x) to that, that would mean x = 0. So on that g(x) graph, when the x=0, the graph intercepts the y axis at y = 1.
Now that we know that g(0) = 1, we can plug that into the original equation, making it f(1) instead of f(g(0)). Now that we have f(1), we can go to our f(x) equation.
Matching the equations, it shows the x=1. On our f(x) graph, we'll find x=1 and trace down or up (down in this case) to the point where the graph intercepts at that point. Thats where we can then trace that point to the y axis and we see that our line hits the y axis at -2, making that the answer.

the perimeter of a triangle is 32 feet. One side of the triangle is 11 feet longer than the second side. The third side is 9 feet longer than the second side. Find the length of each side.
Answer:
One side - 15 feet
Second side - 4 feet
Third side - 13 feet
Step-by-step explanation:
Let's call the sides A B and C, respectively.
We know that:
A = B + 11
C = B + 9
and that
A + B + C = 32
Please note that we have 3 equations and 3 unknowns. We can solve this, we'll use substitution.
A + B + C = (B + 11) + B + (B + 9) = 32
3B + 20 = 32
3B = 12
B = 4
The sides have lengths of 4+11 = 15, 4 and 4+9 = 13. This is in fact a proper triangle (because the shorter sides add up to more than the longer side).

At what time since leaving their flowers do Bee 1 and Bee 2 have the same distance remaining?
By reading the given graph with the two linear functions, we want to see at which time do the two bees have the same distance remaining. We will see that the correct option is B, 6 minutes.
So, in the graph, we have distance remaining on the vertical axis and time on the horizontal axis.
We also have two lines, each one describing the distance of each bee as a function of time.
We want to see at which time do the two bees have the same distance remaining, thus, we need to see when the lines intersect (this means that for the same time, the two bees have the same distance remaining).
In the graph, we can see that the intersection happens at the time of 6 minutes, thus the correct option is B; 6 minutes.

The distance from the north most ship to the observation is

The distance from the south most ship to the observation is

The distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.
The bearing is defined as the angle measured clockwise from the north direction. A ship is anchored off a long straight shoreline that runs north and south.
From two observation points miles apart on shore, the bearings of the ship are 52 degrees and 134 degrees respectively. To find the distance from the ship to each of the observation points, we can use trigonometry.
Let's call the distance from the north observation point to the ship x, and the distance from the south observation point to the ship y. The bearings from the north and south observation points can be drawn as follows:
[asy]
unitsize(1cm);
pair O = (0,0), N = (-2,0), S = (2,0), A = (-2,1), B = (2,-1);
draw(O--N--A,Arrow);
draw(O--S--B,Arrow);
\(label("$52^\circ$", N + 0.3*dir(52), NE);\)

draw(O--A--B--cycle,dashed);
\(label("$x$", (N+A)/2, W);\)
\(label("$y$", (S+B)/2, E);\)
[/asy]
We can use the tangent function to find x and y, since we have the angle and opposite side.
From the north observation point, we have:
\($$\tan(52^\circ) = \frac{x}{2}$$$$x = 2\tan(52^\circ) \approx 2.95$$\)
From the south observation point, we have:
\($$\tan(134^\circ) = \frac{y}{2}$$$$y = 2\tan(134^\circ) \approx 9.88$$\)
Therefore, the distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.
