Answers
An antique painting is purchased in 1980 for $995. The value increases by 3.1% every year, the increase in value of the painting in the 6th year after it was purchased is: $200.02
What is increase in value?Increased Value is the amount obtained after deducting the Base Value from the current assessed value.
Given that,
An antique painting is purchased in 1980 for $995 = P
The value increases by 3.1% every = r
r = 3.1%
r = 3.1/100
r = 0.031
As we know,
Value of painting after t years: [tex]P (1+r)^t[/tex]
So, after 6 years:
f(6) = [tex]995 (1+0.031)^6[/tex]
or, f(6) = [tex]995 (1.031)^6[/tex]
or, f(6) = 1195.0197
or, f(6) = 1195.02
Now, at t = 0, f(0) = 995
Thus, value increased by, f(6) - f(0)
= [1195.02 - 995]
= 200.02
Thus, increase in price since it purchased = $200.02

Graph triangle lmn with vertices l(1,6), m(-2,4), and n (3,2) and its
image after the composition.
Rotation: 90 about the origin
Translation: (x,y) (x-3,y+2)
Answers
The final image of triangle LMN is triangle L''M''N'' with vertices L''(-3,-5), M''(1,-4), and N''(-1,-1).
What is Translation of graph?
A graph can be horizontally translated by moving the base graph to the left or right in relation to the x-axis. Each point on a graph is moved by k units in order to translate it horizontally.
To graph triangle LMN and its image after the composition of a 90 degree rotation about the origin and a translation of (x, y) (x-3, y+2), we can first plot the vertices of triangle LMN on the coordinate plane.
pair L = (1,6);
pair M = (-2,4);
pair N = (3,2);
Next, we can apply the 90 degree rotation about the origin to the vertices of the triangle. The rotation matrix for a 90 degree rotation about the origin is given by:
[cos(90) -sin(90)][x] [y]
[sin(90) cos(90)][y] = [-x]
Substituting the coordinates of the vertices into the rotation matrix, we get:
[cos(90) -sin(90)][1] [6]
[sin(90) cos(90)][-2] = [4]
[3] [2]
Therefore, the image of triangle LMN after the rotation is triangle L'M'N' with vertices L'(-6,1), M'(4,-2), and N'(-2,3).
Finally, we can apply the translation of (x, y) (x-3, y+2) to the vertices of the rotated triangle to get the final image of triangle LMN. The translation matrix is given by:
[tex][1 \ 0][x] [y][-3 \ 2][y] = [x-3][/tex]
Substituting the coordinates of the rotated vertices into the translation matrix, we get:
[1 0][-6] [1]
[-3 2][4] = [-1]
[-2] [3]
Therefore, The final image of triangle LMN is triangle L''M''N'' with vertices L''(-3,-5), M''(1,-4), and N''(-1,-1).

Ms. D'Amico bought a car with a 20% down payment, which was 5,750. She will finance the rest of the car payments. What was the price of the car?
Answers
Answer:
$28,750
Step-by-step explanation:
To find the price of the car, you need to use the following formula:
price of the car = down payment / (down payment percentage / 100)
Plugging in the given values, you get:
price of the car = 5,750 / (20 / 100)
Simplifying the expression, you get:
price of the car = 5,750 / 0.2
The price of the car is therefore 28,750.

You decide to invest $500 into a 4-year CD that pays 2.85% interest
compounded monthly.
Use the compound interest formula:A = P(1 + r/n) ^nt to give:
a. The future value in 4 years.
b. The interest gained in 4 years.
Answers
Future value in four years is $1060.30 and Interest gained in four years is 560.30.
Define compound interest.Compound interest is interest that builds up over a set length of time on both principal and interest. The principal is also used to account for the interest that has accrued on a principal over time. Furthermore, the accumulated principal value is used to calculate interest for the subsequent time period. The new way of calculating interest now utilized in all international financial and commercial operations is known as compound interest. When we look at the compound interest values that have built over successive time periods, the power of compounding is clearly apparent.
Given
You decide to invest $500 into a 4-year CD that pays 2.85% interest compounded monthly
Compound interest
A = P( 1+ r/n)^nt
Interest gained in 4 years
A = 500( 1+ 0.0285/12)^(12)(4)
A = 500( 1 + 0.002375) ^48
A = 560.30
Future value in 4 years = $500 + $560.30
Future value in 4 years = $1060.30
Future value in four years is $1060.30 and Interest gained in four years is 560.30.

three sides of a triangle are 3, radical7, and 4. Is the triangle acute, right or obtuse?
Answers
Answer: To determine whether a triangle is acute, right, or obtuse, we need to compare the lengths of its sides to the measure of its angles. The triangle is acute if all three angles measure less than 90 degrees, it is right if one angle measures exactly 90 degrees, and it is obtuse if one angle measures more than 90 degrees.
In the case of a triangle with sides 3, radical7, and 4, we can use the Pythagorean theorem to find the measure of its angles. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Since we know that one side of the triangle has length 4, and another side has length radical7, we can use the theorem to find the length of the third side, which is the hypotenuse. We can write this as an equation: 4^2 + radical7^2 = x^2, where x is the length of the hypotenuse. Solving for x, we get x = 5.
Since the length of the hypotenuse is 5, and one of the other sides has length 4, we can conclude that this triangle is a right triangle. Therefore, the triangle is a right triangle and not acute or obtuse.

two sheets of plywood are leaning up against one another, forming a small camping shelter. One sheet of plywood is 7 feet long and makes a 31 degree angle with the ground. The other sheet of plywood is 4 feet long. What is the approximate measure of the angle made between the two pieces of plywood.
Answers
The angle made between the two pieces of plywood found using the law of sines is approximately 85°
The law of sines states that the ratio of the sine of an angle to the length of the opposite side is the same for the three angles and sides of the triangle.
[tex]\dfrac{sin(A)}{a} = \dfrac{sin(B)}{b} = \dfrac{sin(C)}{c}[/tex]
The length of one plywood = 7 feet
The angle made by the 7 feet plywood with the ground = 31°
Length of the other sheet of plywood = 4 feet
Using the law of sines, we get;
sin(31)/4 = sin(B)/7
sin(B) = 7 × (sin(31)/4)
∠B = arcsine(7 × (sin(31)/4)) ≈ 64.33°
The angle between the two pieces of wood is therefore;
Angle = 180° - 31° - 64.33° = 85°
The measure of the angle formed between the two plywood is about 85°

D. Multiply the first equation by 3 and the second equation by 2
Answers
The strategy that does not work to solve the system is the one in option D
"Multiply the first equation by 3 and the second equation by 2"
Which one is not a valid strategy?Here we have the following system of equations:
4x - 3y = 8
2x + 9y = -3
To solve it, we can take a linear combination of the two equations, for example if we do what the first option says and we multiply the first equation by 3 we get:
3*4x - 3*3y = 3*8
12x - 9y = 24
Now we can add this to the other equation to get:
(12x - 9y) + (2x + 9y) = 24 - 3
14x = 21
And the system can be solved.
Now, the option that does not help us to solve the system is the third option:
"Multiply the first equation by 3 and the second equation by 2"
If we do that we will get the equations:
12x - 9y = 24
4x + 18y = -6
If we add these two equations no variable is canceled.
