-2x + y = 4 -6x + y = -20 Solve by Substitution : // Solve equation [2] for the variable y [2] y = 6x - 20 // Plug this in for variable y in equation [1] [1] (6x-20) - 2x = 4 [1] 4x = 24

Answer:

mAngleW = 130°

Step-by-step explanation:

AngleT is 65°. AngleT cuts off arcUV. So then arcUV is 130°

AngleT is an inscribed angle, so the arc is double the angle.

Since arcUV is 130° then the central angle, angleW is also 130°

Rounding to the nearest degree, the angle of depression from the airplane to the airport is 22 degrees.

What is the angles of depression from the airplane to the airport ?

We can see that the angle of depression is the angle between the horizontal ground and the line of sight from the airplane to the airport.

Using the tangent function, we have:

tan(θ) = opposite / adjacent

where opposite = height of airplane = 3 miles, and adjacent = distance from airplane to airport = 7.5 miles.

So, tan(θ) = 3 / 7.5

Taking the inverse tangent of both sides, we get:

θ = tan⁻¹(3 / 7.5) ≈ 22 degrees

Therefore, the angle of depression from the airplane to the airport is approximately 22 degrees (rounded to the nearest degree).

Answer:

To write the equation of the line that passes through the points (2, -4) and (0, -4), we can use the point-slope form of a linear equation, which is:

y - y1 = m(x - x1)

Where (x1, y1) is one of the points on the line, and m is the slope of the line.

In this case, both points have the same y-coordinate, which means that the line is horizontal and has a slope of 0. We can choose either point to use in the equation, so let's use (2, -4):

y - (-4) = 0(x - 2)

Simplifying this equation, we get:

y + 4 = 0

y = -4

So the equation of the line that passes through the points (2, -4) and (0, -4) is y = -4, which is a horizontal line at y-coordinate -4.

Polynomials are expressions that have multiple terms.

Breaking Apart Polynomials

When multiplying by a polynomial, we can break apart one of the polynomials, and multiply by each term individually. This means to multiply 3x² + x - 1 by 4x + 5, we can break apart the binomial into its separate terms. Instead of trying to multiply everything at once, we can multiply the trinomial by 4x and then multiply the trinomial by 5. Finally, add together the 2 products for the final answer.

Multiplying Polynomials

First, let's multiply the trinomial by 4x.

To find the product, multiply each term of the trinomial by 4x, then add them back together.

So, the first product is 12x³ + 4x²- 4x. Next, let's multiply 5(3x² + x - 1) the same way.

This means that the second product is 15x² + 5x - 5. Finally, let's add the 2 products together.

Then, simplify the expression.

This gives us our final answer. The product of 3x² + x - 1 and 4x + 5 is 12x³ + 19x² + x - 5.

We may square the reciprocals by applying the formula (a/b)² = a²/b²:

=> 1/(tan²(ɵ)) * sin²(ɵ) + 1/(co²(ɵ)) * cos²(ɵ)

=> sin²(ɵ) / tan²(ɵ) + cos²(ɵ) / cot²(ɵ)

=> tan²(ɵ) + 1 = sec²(ɵ)

=> cot²(ɵ) + 1 = csc²(ɵ)

=> sin²(ɵ) / sec²(ɵ) + cos²(ɵ) / csc²(ɵ)

=> 1/cos²(ɵ) = sec²(ɵ)

=> 1/sin^2(ɵ) = csc^2(ɵ)

=> sin²(ɵ) * cos²(ɵ) + cos²(ɵ) * sin²(ɵ)

=> sin²(ɵ) * cos²(ɵ) + sin²(ɵ) * cos²(ɵ)

The length of the side b for the right triangle ABC is equal to 5.276, and the measures of angle A and B are 64 and 26 to the nearest degree using the sine rule.

The sine rule is a relationship between the size of an angle in a triangle and the opposing side.

The side length b is derived using the Pythagoras rule as follows:

b = √(12.2² - 11²)

b = 5.276

Using the sine rule;

12.2/sin90 = 11/sinA

A = sin⁻¹(11 × sin90)/12.2 {cross multiplication}

A = 64.4

12.2/sin90 = 5.3/sinB

B = sin⁻¹(5.276 × sin90)/12.2 {cross multiplication}

B = 25.6

As a result of probability, there is a 1/1326 chance of drawing a red 4 and selecting a queen of diamonds.

A measure of an event's likelihood is probability. It is represented by a number between 0 and 1, where 0 denotes the impossibility of an event and 1 denotes its certainty.

For instance, you can get either heads or tails when you flip a coin. Given that there is only one way to receive heads and a total of two outcomes, the chance of receiving heads is half (or 0.5).

Since there are two red fours in a deck of 52 cards, the likelihood of drawing one is one in every 52 draws.

Since there are 51 cards in the deck after drawing the red 4, the likelihood of getting a queen of diamonds is 1/51 if you decide to keep the red 4.

Since the outcomes of these two occurrences are interdependent (the first event's outcome influences the second event's outcome), we may multiply their probabilities to determine the likelihood that both events will occur:

(2/52)× (1/51) = 1/1326

As a result, there is a 1/1326 chance of drawing a red 4 and selecting a queen of diamonds.

The actual amount of drink made for the third batch, however, was only 8 liters. This implies that the third batch's recipe contained less pineapple.

We are told that each liter of pineapple juice yields the same amount of drink. This is referred to as the "r" ratio. Then:

r = d/p

We can use the provided data to get a table of r values shown in below image form.

The ratio for the first two data points is the same, but it is different for the third. This suggests the drink's recipe changed between the second and third batches.

We can calculate the ratio using the first two data points:

r = d/p = 2/1 = 6/3

So the ratio is 2, which means that we obtain 2 liters of drink for every liter of pineapple juice.

This ratio can be used to calculate the estimated amount of drink for the third batch:

d = r*p = 25 = 10
