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°

one real eigenvalue. find this eigenvalue, its multiplicity, and the dimension of the corresponding eigenspace.

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.

c) The dimension of the eigenspace is 1 (because the multiplicity determines the dimension of the eigenspace)

George is 17.55 cm taller than Alex. By simply subtracting the heights of the two, we get the required change between them.

Decimal subtraction is as similar to normal number subtraction. Here the subtraction starts from the decimals or the digits after the decimal point.

It is given that,

The height of George is 89.99 cm and the height of Alex is 72.44 cm.

Since 89.99 cm > 72.44 cm; George is taller than Alex.

To know how much he is taller, we just simply subtract the height of Alex from the height of George.

I.e., 89.99 cm - 72.44 cm = 17.55 cm

Therefore, George is 17.55 cm taller than Alex.

Answer:

7, - 28 , 112 , - 448 , 1792

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

a₅ = a₄ × - 4 = - 448 × - 4 = 1792

When the coloured water evaporates and condenses on the inside of the top cup, there is no colour in the water on the inside surface of the cup.

As water molecules in the air cool, they slow down and combine into tiny droplets of liquid water. This process is called condensation. This happens when water molecules in the air touch the outside of a cold mug exposed to air.

Water vapour in the air is extracted by several techniques, such as cooling the air below the dew point, exposing the air to a desiccant, using membranes that allow only water vapour to pass, collecting the mist, or pressurizing the air. I can do it.

Common examples are water forming on the outside of a cold mug, or moisture forming on a car window on a cool night.

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

Answer: A.

Step-by-step explanation: On the vertical number line, 2 1/5 is located below 2 3/5.

To compare the values of 2 1/5 and 2 3/5, you need to first convert them to fractions with a common denominator. For example, you can convert 2 1/5 to a fraction with a denominator of 5 by multiplying the numerator (1) and the denominator (5) by 2: 2 1/5 = (2 * 1)/(2 * 5) = 2/10 = 1/5.

Then, you can add the fractions to get a common denominator: 2 1/5 + 2 3/5 = (2 + 2) + (1/5 + 3/5) = 4 + (4/5) = 4 4/5.

Since 4 4/5 is greater than 4, it follows that 2 3/5 is greater than 2 1/5. Therefore, on the vertical number line, 2 3/5 is located above 2 1/5.

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.
