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

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

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).

The solution to an inequality is given in set-builder notation as {x l x > two-thirds}.

option c. (two-thirds, [infinity]) is the correct option

The set-builder notation can also be used to express sets using an interval or an equation. It is common practise for sets with an unlimited number of elements to write and represent their elements in this way. This makes use of a variable (or several) that fit under the group of typical numerical kinds, such as integers, real numbers, and natural numbers.

The roster notation is a convenient way to express sets mathematically. Within the curly braces of the roster form, the elements (or members) of a set are listed in a row. In a roster notation, a comma is used to indicate the separation of every two elements when the set contains more than one element.

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.

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.

The correct order of sentences to bisect the angle Q is (1) draw a line from Q to where the arc crosses (2) vertex: set the compass to any convenient width (3) from where the arc crosses lag, make an arc.. (4) place the compass point on the angle Q.

We should know that an angle is the intersection of two or more straight lines.

In construction of angles, using the compass, the first thing is to locate a point say Q.  The open the leg of the compass to a convinient radius, make an arc at another point say P.  From the point P, bisect the initial arc so made then joion to the starting point Q.

Second, from the point where the arcs met on the two lines, make another two arcs above the points, then join them to the starting point Q

By using the formula of circumference and area of circle, it can be calculated that-

Area of the rug = 379.94 sq. inches

What is area and circumference of a circle?

Area of a circle is the total space taken by the circle.

If r is the radius of the circle, then area of the circle is calculated by the formula

Area = [tex]\pi r^2[/tex]

Circumference of a circle is the length of the boundary of a circle

If r is the radius of a circle, then circumference of a circle is calculated by the formula

Circumference = 2[tex]\pi[/tex]r

Let the radius of the rug be r inches

Circumference = [tex]2 \times \pi \times r[/tex] inches

                         = 2 [tex]\times[/tex] 3.14 [tex]\times[/tex] r

                         = 6.28 r

By the problem,

6.28 r = 69.08

r = [tex]\frac{69.08}{6.28}\\[/tex]

r = 11 inches

Area of the rug = 3.14 [tex]\times[/tex] 11  [tex]\times[/tex] 11

Hi use the sine rule: answer: 26.43

Step-by-step explanation:

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°

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"

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

Future value in four years is $1060.30 and Interest gained in four years is 560.30.

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
