Step-by-step explanation:

to obtain a term in the sequence multiply the previous term by r , so

a₁ = 7

a₂ = a₁ × - 4 = 7 × - 4 = - 28

a₃ = a₂ × - 4 = - 28 × - 4 = 112

a₄ = a₃ × - 4 = 112 × - 4 = - 448

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.

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.

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 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 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

What is eigenvalue?

In linear algebra, an eigenvector or characteristic vector of a linear transformation is a nonzero vector that, when the linear transformation is applied to it, changes at most by a scalar factor. The factor by which the eigenvector is scaled is known as the associated eigenvalue, frequently denoted by lambda.

a) -4

b) 1

c) 1

Step-by-step explanation:

a) The matrix A is given by:

[tex]A=\left[\begin{array}{ccc}-3 & 0 & 1 \\2 & -4 & 2 \\-3 & -2 & 1\end{array}\right]\\[/tex]

where lambda are the eigenvalues and I is the identity matrix. By replacing you obtain:

[tex]A-\lambda I=\left[\begin{array}{ccc}-3-\lambda & 0 & 1 \\2 & -4-\lambda & 2 \\-3 & -2 & 1-\lambda\end{array}\right][/tex]

and by taking the determinant:[tex]\begin{aligned}& {[(-3-\lambda)(-4-\lambda)(1-\lambda)+(0)(2)(-3)+(2)(-2)(1)]-[(1)(-4-\lambda)(-3)+(0)(2)(1-} \\& \lambda)+(2)(-2)(-3-\lambda)]=0 \\& -\lambda^3-6 \lambda^2-12 \lambda-16=0\end{aligned}[/tex]

and the roots of this polynomial is:

[tex]\begin{aligned}& \lambda_1=-4 \\& \lambda_2=-1+i \sqrt{3} \\& \lambda_3=-1-i \sqrt{3}\end{aligned}[/tex]

hence, the real eigenvalue of the matrix A is -4.

b) The multiplicity of the eigenvalue is 1.

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).

each scarf's 0.4166 yards of blue scarf

This problem can be solved using a straightforward algebraic equation. For each scarf, Ayana requires many yards of blue cloth.

When solving a straightforward equation, visualize the equals symbol (=) as the fulcrum or center of a balance.

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

In order to answer this question, let's say that each scarf needs x square inches of purple fabric and y square inches of blue fabric.

A total of six scarves are reportedly required. It is assumed that a total of 10 yards of fabric—the combined amount of the purple and the blue fabrics—will be utilized.

So that we may solve this equation.

We use x and y as 6x and 6y as 6 scarves are needed.

10 yards of cloth were used in total (6x + 6y).

Next up It goes without saying that 1 yard of purple cloth is required for each and every scarf.

Therefore, a total of 6 * 1(1/4) yards is required for 6 scarves.

As a result, 6x becomes 6 * 1/4 yards.

This equates to 6 yards of purple material

We now solve for the required amount of blue cloth.

6y = 10 -30/4  = 40-30/4 = 10/4

However, the yards are for six scarves, therefore we need to divide it by six to obtain the amount of material for one scarf.

Each scarf needs 0.4166 yards of blue fabric, or y = (10/4)/6 =10/4 *1/6 =10/24 = 5/12 yards.
