Answer:
Step-by-step explanation:
Given that:
[tex]r = 2.1x^2 - 14.3x + 35[/tex]
For year 2000; x = 0
So; [tex]r (0) = 2.1(0)^2 - 14.3(0) + 35[/tex]
[tex]r (0) = 35[/tex]
For year 2001; x = 1
[tex]r (1) = 2.1(1)^2 - 14.3(1) + 35[/tex]
[tex]r (1) =22.8[/tex]
For year 2002; x = 2
[tex]r (2) = 2.1(2)^2 - 14.3(2) + 35[/tex]
[tex]r (2) = 14.8[/tex]
For year 2003; x = 3
[tex]r (3) = 2.1(3)^2 - 14.3(3) + 35[/tex]
[tex]r (3) = 11[/tex]
For year 2005; x = 5
[tex]r (5) = 2.1(5)^2 - 14.3(5) + 35[/tex]
r(5) = 16
For year 2010; x = 10
[tex]r (10) = 2.1(10)^2 - 14.3(10) + 35[/tex]
[tex]r(10) = 102[/tex]
For year 2018; x =18
[tex]r(18) = 2.1(18)^2 - 14.3 (18) + 35[/tex]
[tex]r(18) = 458[/tex]
Thus, the table can be presented as seen below.
Year 2000 2001 2002 2003 2005 2010 2018
x 0 1 2 3 5 10 18
r(x) 35 22.8 14.8 11 16 102 458
SO, we will notice that the revenue for the albums starts decreasing and when it reaches the minimum, it started increasing with increasing x.
The attribute behind this trend is because the revenue function r(x) typically implies that it is a quadratic function.

How much interest do you earn when you deposit $100 at 25% for 2 years?
Answer:
For simple interest: $50, for compound interest: $56.25
Step-by-step explanation:
For simple interest: 25% *100 = $25
$25*2 = $50
For compound interest:
Year 1) 100+100(.25) = 125
Year 2) 125+125(.25) = 125+31.25 = $156.25
156.25 - 100 = $56.25
Answer:
Year 1) 100+100(.25) = 125
Year 2) 125+125(.25) = 125+31.25 = $156.25
156.25 - 100 = $56.25
Step-by-step explanation:
Brad has 10 lb of oranges to make 12 bowls of fruit salad. His recipe requires 12 oz of oranges for each bowl. Does Brad have enough oranges? Please answer....
Answer: Yes, Brad has enough oranges.
Step-by-step explanation:
Given :
The orange required for one bowl = 12 oz
Thus orange required for 12 bowls = [tex]\frac{12}{1}\times 12=144oz[/tex]
Oranges available with Brad for 12 bowls = 10 lb = [tex]10\times 16=160oz[/tex]
(1lb=16oz)
As organges required is less than oranges available with Brad, thus Brad has enough oranges.

Graph the line that passes through the points (−5,1) and (5,−7) and determine the equation of the line.
Note: this answer assumes that it can be written in point-slope form.
Answer:
Equation: [tex]y - 1 = -\frac{4}{5} (x+5)[/tex]
Graph is attached below.
Step-by-step explanation:
1) First, find the slope of the two lines using the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Use the x and y values of the two points given and solve:
[tex]\frac{(-7)-(1)}{(5)-(-5)}\\= \frac{-7-1}{5+5}\\= \frac{-8}{10}\\= \frac{-4}{5}[/tex]
Therefore, the slope is [tex]\frac{-4}{5}[/tex].
2) Next, use the point-slope formula [tex]y-y_1 = m(x-x_1)[/tex] to write the equation. The [tex]m[/tex] represents the slope of the line, so substitute [tex]\frac{-4}{5}[/tex] for
[tex]y - (1) = -\frac{4}{5}(x-(-5)\\y - 1 = -\frac{4}{5} (x+5)[/tex]
Therefore, [tex]y - 1 = -\frac{4}{5} (x+5)[/tex] is the equation of the line.
3) To graph the equation, you can just plot the points (-5,1) and (5,-7) and draw a line with arrows passing through them. After all, you only need two points to graph a line. The graph is attached below.
Equation of the line is 5y - 4x + 55 = 0 .
What is two point form?The equation of a line can be written if two points are known from where it passes. The equation of a line which passes through (x1, y1) and (x2, y2) can be written as: [tex]y - y1 = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]
Given,
Line passes through (−5,1) and (5,−7) .
Using two point form,
[tex]y - 1 = \frac{(-7) - 1}{5 - (-5)} (x - (-5))[/tex]
= 10y - 10 = -8x + 80
= 5y - 4x + 55 = 0
Hence, equation of the line is 5y - 4x + 55 = 0 .

solve using elimination 10x - 9y = -8 and 2x - 8y = -14
Answer:
x = 1, y = 2
Step-by-step explanation:
Multiply 2x - 8y = -14 by 5 to get 10x - 40y = -70
Subtract (10x - 40y = -70) - (10x - 9y = -8)
Solve -31y = -62 for y
y = 2
Plug in y value to get x value
x = 1
There are red and blue marbles in a bowl. There are twice as many blue 20

Write an equation in point-slope form of the line having the given slope that contains the given point. then graph the line
(dont think u can graph so its okay)
Answer:
The line of the equation in the point-slope form of the line passing through the point (4, -2) and having slope 2 will be:
[tex]y+2=4(x-4)[/tex]
Please check the attached graph.
Step-by-step explanation:
Given
The slope m = -2The point (4, -2)Point slope form:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = 4
The point (x₁, y₁) = (4, -2)
substituting the values m = 4 and the point (x₁, y₁) = (4, -2) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-2) = 4(x-4)[/tex]
[tex]y+2=4(x-4)[/tex]
Thus, the line of the equation in the point-slope form of the line passing through the point (4, -2) and having slope 2 will be:
[tex]y+2=4(x-4)[/tex]

Find the area of the isosceles triangle.
13 cm
10 cm
Answer:
Area of the triangle = 60 cm²
Step-by-step explanation:
Two equal sides of the given isosceles triangle measure 13 cm.
Third side of the triangle = 10 cm
Since, formula to get the area of a triangle with given three sides is given by,
Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where a, b and c represent the sides of the triangle
And s = [tex]\frac{a+b+c}{2}[/tex]
For the given isosceles triangle,
s = [tex]\frac{13+10+13}{2}[/tex]
s = 18
(s - a) = (18 - 13) = 5 cm
(s - b) = (18 - 10) = 8 cm
(s - c) = (18 - 13) = 5 cm
Substituting these values in the formula,
Area of the triangle = [tex]\sqrt{18\times 5\times 8\times 5}[/tex]
= [tex]\sqrt{3600}[/tex]
= 60 cm²
Therefore, area of the given isosceles triangle is 60 square cm.
