Answer:

Step-by-step explanation:

The angle θ = 90° is not a solution to trigonometric equation sin 2θ = 1. (Right choice: A)

In this problem we must determine what angle is not a solution of a given trigonometric equation. The solution set is found by means of algebra properties and trigonometric formulas:

sin 2θ = 1

2θ = 90° + 360° · i, where i is a whole number.

θ = 45° + 180° · i

According to this expression, θ₁ = 45°, θ₂ = 225° and θ₃ = - 135° are solutions to this equation. θ = 90° is not a solution of sin 2θ = 1.

Answer:

Step-by-step explanation:

2x - 8y = - 18

    - 8y = - 2x - 18

         y = ¼x + 2¼

y intercept occurs when x = 0, so b = 2¼  (0, 2¼)

x intercept occurs when y = 0

0 = ¼x + 2¼

¼x = - 2¼

  x = -9     (-9, 0)

Answer:

Admin. tickets: 131

Teacher tickets: 218

Step-by-step explanation:

Let t = the number of teacher tickets

Let a = the number of admin tickets

t + a = 349

.6t + .9a = 248.70  teacher pay 60 cents and admin pays 90 cents.

Solve the first equations for t

t + a = 349

t = 349 -a  Substitute 349 - a for t into the second equation

.6(349 -a) + .9a = 248.70  I want to clear the decimal, so I will multiply through by 10

6 (349 - a) + 9a = 2487  Distribute the 6

6(349) - 6a + 9a = 2487

2094 - 6a + 9a = 2487  Combine like terms

2094 + 3a = 2487  Subtract 2094 from both sides

3a = 393  Divide both sides by 3

a = 131  This is the number of admin tickets purchases.

Plug 131 for a into either of the first two equations

t + a = 349

t + 131 = 349  Subtract 131 from both sides of the equations

t = 218

The purchase for teachers $130.8 and for administrators $117.9.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the number of teacher be x.

So, for Teacher after discount raffle tickets will be 0.60x

and, for administrators after discount raffle tickets will be 0.90(349-x)

Now, Total spent on raffle tickets=$248.70

248.70 = 314.1 - 0.9x + 0.6x

-65.4 = -0.3x

x= 218

Thus, for teachers $130.8 and for administrators $117.9

Answer:

Draw a diagonal line through the points (0,-2) and (8,0) as the graph represents below.

Step-by-step explanation:

First thing first, to graph this equation, as the question specifies, we should find two points. The easiest points to find are the x and y intercepts. We can easily find the y intercept as our equation is in slope-intercept form (y=mx+b, where b is the y intercept). Therefore, our y intercept is -2 and the point that we can plot is (0,-2). Next, we can find our x intercept by solving the equation for x when y is equal to 0.

1) Substitute 0 for y. 2) Add 2 to both sides of the equation. 3) Divide both sides of the equation by 1/4.

\(y = \frac{1}{4}x -2\\\\0=\frac{1}{4}x-2\\\\2=\frac{1}{4}x\\\\8=x\\\\x=8\)

Having solved for x, we now know that the x intercept of the graph is the point (8,0).

Now we can plot these points and draw a diagonal line through the points, and we should get a graph that looks like this:

The rank of the matrix is 3, since there are three linearly independent rows.

The rank of a matrix is the maximum number of linearly independent rows or columns in the matrix. It is denoted by the symbol "rank(A)" for a matrix A.

To find the rank of the matrix:

[-2, -1, -3, -1] [ 1, 2, -3, -1] [ 1, 0, 1, 1] [ 0, 1, 1, -1]

We can perform row operations to reduce the matrix to row echelon form, which will help us determine the rank.

\(R_2 = R_2 + 2R_1 R_3 = R_3 + 2R_1 R_4 = R_4 + R_2\)

This gives us the following matrix:

[-2, -1, -3, -1] [ 0, 0, -9, -3] [ 0, -1, -1, 1] [ 0, 0, -4, -4]

We can see that the third row is not a linear combination of the first two rows, and the fourth row is not a linear combination of the first three rows. Therefore, the rank of the matrix is 3, since there are three linearly independent rows.

Arithmetic operations is a branch of mathematics that studies numbers and the operations on numbers that are useful in all other branches of mathematics. It consists primarily of operations like addition, subtraction, multiplication, and division.

We have,

the job will pay 2400 per month,

if the full cost of the medical insurance is 450 a month and Karla plans to contribute the full 1500 every year tpa retirement plan,

the actual annual value of this job to Karla is:

2400 per month

annual value  = 2400 * 12 = 28,800

the medical insurance is 450 a month

half the cost of medical insurance is  225 a month

annual value  = 225  * 12 = 2700

the full 1500 every year tpa retirement plan,

So, the total value is:

Answer:

  54 yd²

Step-by-step explanation:

The surface area of the prism is the sum of the areas of its faces. Opposite faces have the same area, so we can write the formula as ...

  SA = 2(LW +WH +LH) = 2(LW +H(L +W))

Filling in the numbers, we have ...

  SA = 2(6·3 +1(6 +3)) = 2(18 +9) = 54 . . . . square yards

The area is 54 square yards.

The difference in volume between the two boxes would be = 156in³

To calculate the difference in volume between the boxes is the find the individual volume of the boxes using the formula ;

Volume = length×width×height.

For box 1 = length = 12in, width = 7¾in, height= 2in

Vol = 12×7¾×2 = 186in³

For box 2; length = 3⅔in, width = 3½in, height= 2⅓in

Volume = 3⅔×3½×2⅓ = 30
