Budget planners in two towns, Alphaville and Betaville, developed models to determine the budget surplus (in dollars) for a year based on the tax revenue (in thousands of dollars) for the year. Using historical data, Alphaville’s planner produced the model -2x2+ 500x, while Betaville’s planner produced the model x2- 100x + 10,000. What expression gives how much greater Alphaville’s annual budget surplus is than Betaville’s for a particular amount of tax revenue? If the tax revenue that year in each town is $75,000, how much greater is Alphaville’s budget surplus than Betaville’s that year?

Answer:
(a)[tex]-3x^2+150x-10000[/tex]
(b)[tex]-\$16,863,760,000[/tex]
Step-by-step explanation:
Alphaville's Budget Surplus Model is [tex]-2x^2+ 500x[/tex]
Betaville's Budget Surplus Model is [tex]x^2- 100x + 10000.[/tex]
We want to determine the expression that shows how much greater Alphaville’s annual budget surplus is than Betaville’s for a particular amount of tax revenue.
To do this, we subtract Betaville's Model from Alphaville's model.[tex]-2x^2+ 500x-(x^2- 100x + 10000)\\[/tex]
Opening the brackets
[tex]-2x^2+ 500x-x^2+100x - 10000\\[/tex]
Collect like terms and simplify
[tex]-2x^2-x^2+100x + 500x- 10000\\=-3x^2+150x-10000[/tex]
The expression that shows how much greater Alphaville's Budget is:
[tex]-3x^2+150x-10000[/tex]
(b) If the tax revenue that year in each town is $75,000
We want to evaluate the expression derived above when the tax revenue that year in each town is $75,000 i.e.at x=75000
[tex]-3x^2+150x-10000\\=-3(75000)^2+150(75000)-10000\\=-\$16,863,760,000[/tex]

If f(x) = 3[ x-2], what is f(5.9)
Answer:
f(x)=3[x-2]
So, f(5.9) = ?
f(5.9) = 3(5.9 - 2)
=3(3.9)
=11.7 = 12
so, the answer is 12.

The two conditional relative frequency tables show the results of a neighborhood survey on the number and types of gardens in the community.
A 4-column table with 3 rows titled garden-type frequencies by column. The first column has no label with entries flower garden, no flower garden, total. The second column is labeled vegetable garden with entries 0.28, 0.72, 1.0. The third column is labeled no vegetable garden with labels 0.22, 0.78, 1.0. The fourth column is labeled total with entries 0.25, 0.75, 1.0.
Table B: Garden-Type Frequencies by Row
A 4-column table with 3 rows titled garden-type frequencies by row. The first column has no label with entries flower garden, no flower garden, total. The second column is labeled vegetable garden with entries 0.56, 0.48, 0.5. The third column is labeled no vegetable garden with labels 0.44, 0.52, 0.5. The fourth column is labeled total with entries 1.0, 1.0, 1.0.
Which table could be used to answer the question "Assuming someone has a flower garden, what is the probability they also have a vegetable garden?"
Table A, because the given condition is that the person has a flower garden.
Table A, because the given condition is that the person has a vegetable garden.
Table B, because the given condition is that the person has a flower garden.
Table B, because the given condition is that the person has a vegetable garden.
Answer:
C
Step-by-step explanation:
if youre looking on edge then yeah
Table B, because the given condition is that the person has a flower garden.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Now,
In Table A, there are frequencies by column .
The columns of the table are "Vegetable Garden" and "No Vegetable Garden".
It means if we assume some one as a Vegetable Garden or No Vegetable Garden as initial condition, then Table A works.
In Table B, there are frequencies by rows .
The columns of the table are "Flower Garden" and "No Flower Garden".
It means if we assume some one as a Flower Garden or No Flower Garden as initial condition ,then Table B works.
Hence, Table B could be used to answer the given question because the given condition is that the person has a flower garden.

Find the perimeter of the quadrilateral.
If x = 2, the perimeter is
inches.
Answer:
129 inches
Step-by-step explanation:
If x=2, just substitute in the x values for each side. Your lengths are 31, 32, 22, and 44.
4(2)^2+8(2)= 16+16=32
3(2)^2-5(2)+20=12-10+20=22
7(2)+30= 14+30=44
You are given an additional side of 31.
Add the values up together.

Factor 4x^2 + 49y^2 please.
Answer:
(2x + 7yj)(2x - 7yj)
Step-by-step explanation:
Both 4x^2 and 49y^2 are perfect squares, and
4x^2 + 49y^2 is the sum of two squares.
There is a formula for factoring the difference of two squares:
a^2 - b^2 = (a - b)(a + b) (all real numbers here), but unless imaginary numbers are allowed, there's no formula for factoring the sum of two squares.
If imaginary numbers are allowed, then a^2 + b^2 factors into
(a + jb)(a - jb).
Following this pattern, 4x^2 + 49y^2 factors into (2x + 7yj)(2x - 7yj)
a^2 + b^2 = (a + b)(a

In the trapezoid, what is the measure of 1?
85°
115°
90°
Answer:
115°
Step-by-step explanation:
all angles of a trapezoid add up to 360° and corresponding pairs of base angles add up to 180°. this means that 65° and angle 1 would have to add up to 180°
180 - 65 = 115°
Answer:
85°
Step-by-step explanation:
Since it is a trapezoid one pair of opposite sides will be parallel.
As, AB||CD,
95°+ m<1 = 180°( co- interior angles)

A reporter determines a baseball player’s batting average, which is a ratio of the number of hits to number of times at bat. The result is shown on a calculator as 0.212121....Write this repeating decimal as a fraction.
Answer:
21/99 or 7/33
Step-by-step explanation:
x = 0.212121
Then we multiple the decimal and x by hundred.
100x = 21.212121
Then we subtract the 21.212121 by 0.212121.
100x = 21.212121 - 0.212121
But when you are subtracting 100x, you need to subtract 100x by x because in the first step it said x = 0.212121.
100x - x = 21.212121 - 0.212121
You will have at the end is
99x = 21
Divide 99 on both side and you left with
21/99 or 7/33 simplified version
Use the net to find the surface area of the rectangular prism. A) 168 units2 B) 192 units2 C) 220 units2 D) 224 units2
Answer:
See below.
Step-by-step explanation:
You didn't provide any dimensions to test the answers with, but here is how you could solve the problem.
A rectangular prism is just an oblong cardboard box basically. Think about how you would unfold that box. It would be made up of 3 pairs of rectangles (2 end pieces, the top and bottom, and 2 sides). To calculate its surface area you just calculate the areas of each piece and add them up.
The overall formula ends up being:
Area = 2(LW) + 2(LH) + 2(WH)

Whats the solution system? 2x + 5y = 14 x + 3y = 16
Answer:
Step-by-step explanation:
2x + 5y = 14 -------------(i)
x + 3y = 16 ----------------(ii)
To eliminate x, multiply the second equation by (-2)
(ii)*(-2) -2x - 6y = -32
(i) 2x + 5y = 14 { Now add & x is eliminated}
- y = - 18 {divide by (-1)}
y = 18
Plug in y =18 in Equation (i)
2x + 5*18 = 14
2x + 90 = 14
2x = 14 - 90
2x = -76
x = -76/2
x = -38
Answer:
Step-by-step explanation:
hello :
2x + 5y = 14...(*)
x + 3y = 16....(**)
multiply (**) by -2 : -2x-6y=-32 ...(***)
add(*) and (***) : -y=-18 so y = 18
put this value in to (*) : 2x+5(18)=14
2x = -76
x = - 38

Ac is tangent to circle o at point c what is the length of ac?
Answer:
The Answer is 12
Step-by-step explanation:
Use Pythagorean theorem. AB=8 and BO=5 We still need to find AO
AO=AB+BO
8+5
AO=13
Now solve for AC
AC^2 + OC^2= AO^2
AC^2+5^2=13^2
AC^2+ 25=169
AC^2=144
AC= 12
