The correct order of the functions from least to greatest is g(x), f(x) and h(x).
The given function is f(x)=(x+3)²-2.
g(x) linear graph with y-intercept = c = -3/2 and x-intercept = 3
f (x) = (x + 3)² - 2
For x = -1
f (-1) = (-1 + 3)² - 2
f (-1) = (2)² - 2
f (-1) = 4 - 2
f (-1) = 2
For x = 3
f(3) = (3 + 3)² - 2
f(3) = (6)² - 2
f(3) = 36 - 2
f(3) = 34
AVR = ((34) - (2))/((3) - (- 1))
AVR = 8
For g(x):
linear graph with and intercept of negative 3 over 2 and x intercept of 3
y = mx + b
b = -3/2
For me we have:
0 = m (3) - 3/2
3m = 3/2
m = 1/2
The function g(x) is:
g (x) = (1/2) x - 3/2
For x = -1
g (-1) = (1/2) (- 1) - 3/2
g (-1) = -1/2 - 3/2
g (-1) = -4/2
g (-1) = -2
For x = 3
g (3) = (1/2) (3) - 3/2
g (3) = 3/2 - 3/2
g (3) = 0
AVR = ((0) - (- 2)) / ((3) - (- 1))
AVR = 1/2
For h(x):
Using the table we have:
AVR = ((62) - (14)) / ((3) - (- 1))
AVR = 12
From least to greatest g(x), f(x), h(x)
Therefore, the correct order of the functions from least to greatest is g(x), f(x) and h(x).

Maricopa's Success scholarship fund receives a gift of $ 195000. The money is invested in stocks, bonds, and CDs. Stocks pay 10.1 % interest, bonds pay 4.8 % interest, and CDs pay 4.75 % interest. Maricopa Success invests $ 35000 more in bonds than in CDs. If the annual income from the investments is $ 13580 , how much was invested in each account?
Maricopa Success invested $ in stocks.
Maricopa Success invested $ in bonds.
Maricopa Success invested $ in CDs.
Using a system of equations, the investments in each account are as follows:
Maricopa Success invested $80,000 in stocks.
Maricopa Success invested $75,000 in bonds.
Maricopa Success invested $40,000 in CDs.
What is a system of equations?A system of equations is two or more equations solved simultaneously, concurrently, or at the same time.
The total scholarship fund received = $195,000
The earnings from the investments:
Stocks = 10.1% = 0.101
Bonds = 4.8% = 0.048
CDs = 4.75% = 0.0475
Let the amount invested in CDs = x
Let the amount invested in Bonds = x + 35,000
Let the amount invested in stocks = y
The annual income from the investments = $13,580
Forming Equations:x + x + 35,000 + y = 195,000
2x + 35,000 + y = 195,000
2x + y = 160,000 ... Equation 1
0.101y + 0.048x + 1,680 + 0.0475x = 13,580
0.0955x + 0.101y = 11,900 ... Equation 2
Multiply Equation 1 by 0.101:
0.202x + 0.101y = 16,160 ... Equation 3
Subtract Equation 2 from Equation 3:
0.202x + 0.101y = 16,160
-
0.0955x + 0.101y = 11,900
0.1065x = 4,260
x = 40,000
Substitute x = 40,000 in Equation 1:
2x + y = 160,000
2(40,000) + y = 160,000
80,000 + y = 160,000
y = 80,000
Investment in CDs = $40,000
Investment in Bonds = $75,000 ($40,000 + $35,000)
Investment in Stocks = $80,000

A student is creating a graph to represent the equation y=2/3x-5. Which point is not on the line represented by the students graph? A. (9,1) B. (12,7) C. (15,5) D. (21,9)
Answer: B. (12, 7)
Step-by-step explanation: If we substitute the x values in the equation the answer has to equal the y value of the coordinate. If we substitute 12 for the x we get y = 3. So answer B is the coordinate not represented by the student's graph.

The quotient function for this problem is given as follows:
(f/g)(x) = (x + 2)/(2x² + 4x - 5)
How to obtain the quotient function?The functions f(x) and g(x) have the definitions presented as follows:
f(x) = x + 2.g(x) = 2x² + 4x - 5.To obtain the quotient of the two functions, we simply divided the definition of the function f(x) by the definition of the function g(x).
Both functions are defined on the bullet point, hence the quotient function for this problem is given as follows:
(f/g)(x) = (x + 2)/(2x² + 4x - 5)

I need to know surface area
Answer: 165 ft squared
Step-by-step explanation:
1. First find the area of the bottom face (you don’t need to divide by two because the other triangle makes the one on the bottom a full rectangle.)
10x4.5=45
2. Find area of face facing you. (The lateral one, rectangle face)
10x5=50
3. Find area of left and right lateral faces (its at the back)
6x5=30
8x5=40
4. Add all answers to get total surface area
40+30+50+45=165
5.Add unit and then celebrate because you did it!

A prospector graphed the locations of a gold vein and all of the gold dust strikes in the vicinity. He positioned the gold vein at (-2,7) and the farthest gold dust strike at (74,7). If each unit on the graph
represents 1 mile, then how far away from the gold vein is the farthest gold dust strike?
miles
The farthest gold dust strike is 76 miles away from the gold vein.
The formula of the distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by:
d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ²
As per the question, we have to find the distance between the gold vein at (-2, 7) and the farthest gold dust strike at (74, 7).
Substituting the values into the distance formula, we have:
d = √((74 - (-2))² + (7 - 7)²)
d = √(76²)
d = 76
Therefore, the farthest gold dust strike is 76 miles away from the gold vein.
