Answer:
$40000
Step-by-step explanation:
The formula is x*1.08 = 43200. If you want to find the original price then isolate x. x*1.08 = 43200 -> x = 40000.

The graph of g(x) shown below resembles the graph of f(x) = x2, but it has
been reflected over the x-axis. Which is the equation of g(x)?
Answer:
A. g(x) = - x²
Step-by-step explanation:
f(x) reflex over x-axis: g(x) = - f(x)
Using translation concepts, it is found that the equation of g(x) is given by:
A. g(x) = -x².
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the parent function f(x) = x² was reflected over the x-axis, that is, it was multiplied by -1, hence the equation for g(x) is given by:
g(x) = -f(x) = -x².
Which means that option A is correct.

The half-life of carbon-14 is 5,730 years. Suppose a fossil is found with 30 percent as
much of its carbon-14 as compared to a living sample. How old is the fossil?
28,993 years
9,955 years
2,899 years
996 years
Answer:
Step-by-step explanation:
0.5^(t/5730) = 0.30
2^(-t/5730) = 0.30
-t/5730 = log₂0.30
t = -5730 log₂0.30 ≈ 9953 years

Elizabeth purchased a $20 bus pass. Each time she rides the bus $1.25 is deducted from the pass. What equation would represent this scenario? *
12 points
y= 1.25x - 20
y= -1.25x + 20
y= 20x - 1.25
y= 20x + 1.25
Answer:
Y = 1.25x - 20
Step-by-step explanation:
Everytime she rides the bus 1.25 is taken away from that 20.
The x = Every ride
For example
say she rode the bus 5 times so it would be
1.25 × 5 = 6.25 now you take the answer and subtract it from the 20
20 - 6.25 = 13.75

A square painting has an area of 81x^2 - 90x + 25. A second square painting has an area of 25x^2 + 30x + 9. Part A: What is an expression that represents the difference of the areas of the paintings? Show two different ways to find the solution.Part B: The paintings have areas of 1,600in^2 and 484in^2, respectively. A potential buyer went to an exhibition and argued that the value of xfor both paintings is the same. Is he right? Prove it.
Answer:
56x² - 120x + 16 ; (9x - 5)² - (5x - 3)²
x in both equations is 5
Step-by-step explanation:
Painting 1 : 81x^2 - 90x + 25
Painting 2 : 25x^2 + 30x + 9
Expression for the difference between the two paintings :
Painting 1 - painting 2
(81x^2 - 90x + 25) - (25x^2 + 30x + 9)
81x^2 - 90x + 25 - 25x^2 - 30x - 9
81x² - 25x² - 90x - 30x + 25 - 9
56x² - 120x + 16
2.)
81x^2 - 90x + 25 = 1600in²
25x^2 + 30x + 9 = 484 in²
Factorizing each equation :
81x^2 - 90x + 25 = 1600 in²
(9x - 5)^2 = 1600 in²
25x^2 + 30x + 9 = 484 in²
(5x - 3)^2 = 484
(9x - 5)² - (5x - 3)²
2.)
(9x - 5)^2 = 1600
Take square root of both sides
9x - 5 = 40
9x = 40 + 5
9x = 45
x = 45/9
x = 5
(5x - 3)^2 = 484
Take square root of both sides
5x - 3 = 22
5x = 22 + 3
5x = 25
x = 25/5
x = 5

Find the mean of the first 7 odd prime number?
Answer: 75/7 or 10.71 (rounded)
Step-by-step explanation:
Mean = Average
To find the average you should add all the numbers together and then divide it by the amount of numbers.
In this question, the formula is [tex]\frac{n_1+n_2+n_3+n_4+n_5+n_6+n_7}{7}[/tex]
----------------------------------------------------------------------------------------
The list of the first 7 odd prime numbers:

Use the midpoint formula to estimate the sales of Cars, Inc. in 2009, given the sales in 2008 and 2010. Assume that the sales of Cars, Inc. sales always follow a linear pattern. (Round to nearest whole number) Year Sales (in millions) 2008 240 2010 280 millions Enter the answer
Answer:
The estimated sales were $260 million
Step-by-step explanation:
Assume the endpoints of a segment are (x1,y1) and (x2,y2).
The midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:
[tex]\displaystyle x_m=\frac{2008+2010}{2}=2009[/tex]
[tex]\displaystyle y_m=\frac{240+280}{2}=260[/tex]
The estimated sales were $260 million
Three vertices of a parallelogram are shown in the figure below. Give the coordinates of the fourth vertex.
Coordinates: (-3,8) (4,5) (2,-5)
Given:
The three vertices of a parallelogram are (-3,8), (4,5), (2,-5).
To find:
The fourth vertex of the parallelogram.
Solution:
Let the vertices of the parallelogram are A(-3,8), B(4,5), C(2,-5) and D(a,b).
We know that, diagonals of a parallelogram bisect each other. It means midpoints of both diagonals are same.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Two diagonals of ABCD are AC and BD.
Midpoint of AC = Midpoint of BD
[tex]\left(\dfrac{-3+2}{2},\dfrac{8-5}{2}\right)=\left(\dfrac{4+a}{2},\dfrac{5+b}{2}\right)[/tex]
[tex]\left(\dfrac{-1}{2},\dfrac{3}{2}\right)=\left(\dfrac{4+a}{2},\dfrac{5+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{4+a}{2}=\dfrac{-1}{2}[/tex]
[tex]4+a=-1[/tex]
[tex]a=-1-4[/tex]
[tex]a=-5[/tex]
And,
[tex]\dfrac{5+b}{2}=\dfrac{3}{2}[/tex]
[tex]5+b=3[/tex]
[tex]b=3-5[/tex]
[tex]b=-2[/tex]
Therefore, the coordinates of fourth vertex are (-5,-2).

What is the value of the missing angle ?
Answer:
30
Step-by-step explanation:
? = 180 - 150 = 30
Answer:
30°
Step-by-step explanation:
The line is 180 degrees so all you have to do is subtract 150° from 180°
You should end up with 30°

The angles shown are supplementary. (3x + 15)° 60° What is the value of x?
Answer:
x = 35
Step-by-step explanation:
Supplementary angles add up to 180°.
if (3x + 15)° and 60° are supplementary, then
3x + 15 + 60 = 180
now, you just have to solve the equation.
3x + 75 = 180
3x = 105
x = 35
Check
3*35 + 15 + 60 = 180
105 + 15 + 60 = 180
180 = 180

3. The area A of a triangle varies jointly as the base b and the altitude h of the triangle. If the area
of a triangle is 70 cm2 when the base is 14 cm and the altitude is 10 cm, find the area if the base is
8 cm and the altitude is 12 cm.
Answer:
48cm²
Step-by-step explanation:
If the area A of a triangle varies jointly as the base b and the altitude h of the triangle, this is expressed as;
A = kbh
k is the constant of proportionality
If A = 70cm², b = 14cm and h = 10cm
Substitute
70 = k(14)(10)
70 = 140k
k = 70/140
k = 0.5
To get the area if base is 8 cm and the altitude is 12 cm;
A = 0.5*8*12
A = 48cm²
Hence the required area is 48cm²
