Answer:

  69.9° or 110.1°

Step-by-step explanation:

You want to know the angle opposite the side of length 22 in a triangle in which a 28° angle is opposite a side of length 11.

The law of sines tells you ...

  sin(B)/b = sin(A)/a

  sin(x)/22 = sin(28°)/11

  sin(x) = 22/11 · sin(28°)

  x = arcsin(2·sin(28°)) ≈ 69.9° or 110.1°

__

Additional comment

There are generally two solutions to a Law of Sines problem in which the given angle is opposite the shorter of two given sides. The exception is when the triangle is a right triangle.

What is the expanded form of an expression?

Expanded form, also known as expanded notation, is a method of writing numbers that allows you to see the math value of individual digits. When numbers are separated into individual place values and decimal places, a mathematical expression can be formed.

Most people are introduced to Pascal's triangle via a seemingly arbitrary set of rules. Begin with a 1 on top and 1s running down both sides of a triangle. Each new number is located between and below two other numbers, and its value is the sum of the two numbers above it. The theoretical triangle is infinite and continues indefinitely downward, but only the first six lines are shown in figure 1. More rows of Pascal's triangle are shown in the article's final figure. Another way to look at the triangle is to imagine the first line as an infinite sequence of zeros with the exception of a single 1.Add every adjacent pair of numbers and write the sum between and below them to get successive lines. Pascal's triangle is the non-zero part.

If he works 14 hours then he will earn the amount of $105 which is true and if he works 16 hours then he will earn $120 which is true.

You should be aware that a linear equation is defined as an equation in which the highest power of the variable is one.

The given graph represents Elisa's work and the amount of money he earns at his job.

According to the given graph,

We can see two points are (4, 30) and (8, 60)

The linear equation will be

⇒ y - 30 = (60-30)/(8-4)(x-4)

⇒ y - 30 = (30)/(4)(x-4)

⇒ y - 30 = 7.5(x-4)

⇒ y = 7.5x - 30 + 30

⇒ y = 7.5x

Elisa's work = 14 hours then we verify the response by substituting x = 14 in the above equation,

⇒ y = 7.5(14)

⇒ y = 105

Thus,  if he works 14 hours then he will earn $105

Elisa's work = 16 hours then we verify the response by substituting x = 16 in the above equation,

The quadratic equation has two solutions, x1 = 3.44 and x2 = 0.56

Quadratic equations are the ones with degree 2. The standard form of a quadratic equation with variable x is ax2 + bx + c = 0, where a ≠ 0. These equations can be solved by splitting the factorisation, completing the square, or by quadratic formula method.

2x²-8x+8 = -3

2x²-8x+8+3 = 0

2x²-8x+11=0

Using the quadratic formula

x = (- b ± √(b² - 4ac)) / 2a

where a = 2

b = -8

c = 11

x = (-(-8) ± √(11² - 4(2)(11))) / 2(2)

x = (8 ± √(121 - 88)) / 4

x = (8 ± √(33))/4

x 1 = (8 + √(33))/4

x1 = (8 + √(33))/4

x1 = (8 + 5.75)/4

x1 = 13.75 / 4

x1 = 3.44

Lines of longitude run north to south and measure places expressed in degrees east or west of the Prime Meridian.The basic work of the longitude lines is to show the distance at which a place lies, east or west of the Prime Meridian.

Longitude is a measurement of location east or west of the prime meridian at Greenwich, London, England, the specially designated imaginary north-south line that passes through both geographic poles and Greenwich. Longitude is measured 180° both east and west of the prime meridian.

An triangle is a polygon since it has four or more parts. It is a simple geometric shape. A square having angles A, B, and C is referred to as a triangle ABC. When the sides are not collinear, Euclidean geometry generates a single plane and square. If a triangle has three sides and three corners, it is a polygon. The corners of a triangle are where its three sides meet. The sum of the angles in a triangle is 180 degrees.

Answer: (5, -2)

Step-by-step explanation:

They give you two equations with two variables. You can solve this using elimination or substitution. However, it seems as though the problem wants you to do it through elimination. On the right, you have the equation

    6x + 10y = 10

+  -6x - 24y = 18

After add these equations, you get -14y = 28. By dividing both sides by -14, you get y = -2. You can plug y = -2 back into either one of the original equations, and solve for x.

x = 5.

Answer:

Answer:

  D.  (2x +1)(x -6)

Step-by-step explanation:

You want the expression that is equivalent to 2x² -11x -6.

There are a couple of ways to go at this. One way is to eliminate the answers that make no sense: A and C. We say these are nonsense because they have an overall factor of 2. The coefficient -11 is not a multiple of 2, so there cannot be such a factor.

If you were to examine the remaining choices (after eliminating A and C), you would find the x-term of the product to be ...

  B: 2x(-2) +3(x) = -4x +3x = -x

  D: 2x(-6) +1x = -12x +x = -11x . . . . . the expression we're looking for

If you were to factor this equation, you would look for factors of 2·(-6) = -12 that have a sum of -11. Of course, those are -12 and 1. This means we can rewrite the equation as ...

  2x² -11x -6 = 2x² -12x +x -6

  = 2x(x -6) +1(x -6) . . . . . . . factor by grouping (pairs of terms)

  = (2x +1)(x -6) . . . . . . . . . . matches choice D.

The end behavior of a graph with an odd degree and a positive leading coefficient is that the graph will tend to increase infinity as x approaches positive infinity and decrease to negative infinity as x approaches negative infinity.

This end behavior of a graph is due to the fact that when the degree is odd, the leading coefficient acts as a multiplier for the highest degree term, making its contribution to the graph’s y-value the largest and most dominant. For example, if the equation of the graph is y = 4x^3 + x^2 – 7x + 5, then the end behavior of the graph will be increasing to positive infinity as x approaches positive infinity and decreasing to negative infinity as x approaches negative infinity. To calculate this, we can use the equation y = 4x^3. When x = 1000, y = 4,000,000,000. As x increases, y will continue to increase to positive infinity. When x = -1000, y = -4,000,000,000. As x decreases, y will continue to decrease to negative infinity.
