The equation of the line L that passes through the point (-2, 2) and has a slope of 2 is y = 2x + 6.

To find the equation of a line, we need to use the point-slope form, which is given by y - y₁ = m(x - x₁), where (x₁, y₁) represents a point on the line, and m is the slope. In this case, the given point is (-2, 2), and the slope is 2.

Substituting these values into the point-slope form, we get y - 2 = 2(x - (-2)), which simplifies to y - 2 = 2(x + 2). Distributing the 2 on the right side, we have y - 2 = 2x + 4.

To obtain the slope-intercept form of the equation, which is y = mx + b, we isolate y on the left side of the equation. Adding 2 to both sides, we get y = 2x + 6. Therefore, the equation of line L that passes through the point (-2, 2) with a slope of 2 is y = 2x + 6.

Step-by-step explanation:

The average value of the function f(x) = (x + 2) on the interval [0, 3] is 7/2.

Calculate the definite integral of the function over the interval [a, b], then divide it by the interval's length (b - a), in order to determine the average value of a function f(x) over the interval.

Given that the interval is [0, 3] and the function f(x) = (x + 2), we have:

= (1/3) × [1/2 x² + 2x] evaluated from x=0 to x=3

= (1/3) × [(1/2 × 3² + 2×3) - (1/20² + 20)]

= (1/3) × [(9/2 + 6) - 0]

= (1/3) × (21/2)

= 7/2

Therefore, the average value of the function f(x) = (x + 2) on the interval [0, 3] is 7/2.

How to find angle of the triangle ?

To find the angle of a triangle, you need to know the lengths of its sides or the relationship between the lengths of its sides. There are different methods for finding angles depending on the information you have about the triangle. Here are a few examples:

Law of sines: If you know the lengths of two sides of a triangle and the angle between them, you can use the law of sines to find the angle opposite the longer side. The law of sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides. So, you can set up the equation:

sin(A) / a = sin(B) / b

where A and B are the angles opposite the sides a and b, respectively. Solve for the angle A to find the measure of the angle.

Law of cosines: If you know the lengths of all three sides of a triangle, you can use the law of cosines to find the angle opposite the longest side. The law of cosines states that:

c² = a² + b² - 2ab*cos(C)

where c is the length of the longest side (the side opposite angle C), and a and b are the lengths of the other two sides. Solve for cos(C) and then use the inverse cosine function to find the measure of angle C.

Right triangles: If you have a right triangle, you can use the properties of right triangles to find the angles. The sum of the measures of the two acute angles in a right triangle is always 90 degrees, so if you know one of the acute angles, you can find the other one by subtracting it from 90 degrees.

These are just a few methods for finding angles in a triangle. There are many other techniques depending on the specific information you have about the triangle.

To find the length of LM, we can use the law of sines which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides. That is,

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides of the triangle and A, B, and C are the angles opposite those sides.

In this case, we know the length of KL is 1.2 cm, and we want to find the length of LM. Let's call the length of LM x. Then, we can use the law of sines to set up the following equation:

1.2/sin(93°) = x/sin(81°)

Solving for x, we get:

x = (1.2 × sin(81°)) / sin(93°)

Using a calculator, we get:

x ≈ 4.8 cm

Therefore, the length of LM is approximately 4.8 cm to the nearest 10th of a centimeter.

The second airplane, with a height of 37,890.89 kilometers, has a higher altitude than the first airplane, which is at 37,890.52 kilometers.

To determine which airplane has a higher altitude, we can compare the decimal parts of the altitudes provided.

The first airplane is flying at a height of 37,890.52 kilometers, and the second airplane is flying at a height of 37,890.89 kilometers. Comparing the decimal parts, we can see that 0.52 is smaller than 0.89.

In the decimal system, as the digits move to the right of the decimal point, their value decreases. So, when comparing two numbers with the same whole part (37,890 in this case), the one with a higher decimal part will be greater.

Therefore, the second airplane, with a height of 37,890.89 kilometers, has a higher altitude than the first airplane, which is at 37,890.52 kilometers.

The probability that two men will be selected from the first set and two women will be selected from the second set is 3/10 * 2/3, or 1/5.

The probability of selecting two men from the first set is 3/4. This is because there are 3 men in the first set and the probability of selecting one is 1/4. Since we need to select two, the probability of selecting both is 3/4 multiplied by itself, or 3/4 x 3/4. The probability of selecting two women from the second set is 2/3. This is because there are 2 women in the second set and the probability of selecting one is 1/3. Since we need to select two, the probability of selecting both is 2/3 multiplied by itself, or 2/3 x 2/3. The probability of selecting two men from the first set and two women from the second set is then 3/4 x 3/4 x 2/3 x 2/3, which is equal to 3/10 x 2/3, or 1/5.

The value of x , y and z in the parallel line is 50 degrees.

When parallel lines are crossed by a transversal line, angle relationships are formed such as vertically opposite angles, alternate interior angles, alternate exterior angles, adjacent angles, corresponding angles etc.

Therefore, let's use the angle relationships to find the angle, x, y and z as follows:

Therefore,

x = 360 - 310(sum of angles in a point)

x = 50 degrees

Therefore,

x = y(alternate interior angles)

Alternate interior angles are congruent.

Hence,

y = 50 degrees

The expression 14 × 23 represents the total number of cups of dirt needed for 14 pots of flowers. By multiplying the number of pots (14) by the amount of dirt needed per pot (23), we find that a total of 322 cups of dirt are required to fill all 14 pots.

To calculate the total number of cups of dirt needed for 14 pots of flowers, we can use the expression 14 × 23.

Let's break down the problem and explain the steps involved.

Given information:

Each pot of flowers requires 23 cups of dirt.

We want to find the total number of cups of dirt needed for 14 pots.

To solve this, we can multiply the number of pots (14) by the number of cups of dirt required for each pot (23).

Expression: 14 × 23

When we multiply 14 by 23, we perform the following calculation:

14 × 3 = 42 (multiplying the units digit)

14 × 20 = 280 (multiplying the tens digit)

Summing the results: 280 + 42 = 322

Therefore, the total number of cups of dirt needed for 14 pots is 322 cups.

Let's analyze this further.

When we say that 1 pot of flowers requires 23 cups of dirt, it means that each individual pot needs a specific amount of dirt to be properly filled. Multiplying this amount by the number of pots (14) gives us the cumulative requirement for all the pots.

Using the expression 14 × 23, we are essentially multiplying the number of pots (14) by the amount of dirt needed per pot (23). This expression allows us to find the total quantity of dirt required to fill all 14 pots.

The multiplication process involves multiplying the units digit (4) of 14 by 3, which gives us 12. The result has a carry-over of 1, which we then multiply by the tens digit (2) of 14, resulting in 20. Finally, we add these two products (12 and 20) to obtain the final result of 322.

In conclusion, the expression 14 × 23 represents the total number of cups of dirt needed for 14 pots of flowers. By multiplying the number of pots (14) by the amount of dirt needed per pot (23), we find that a total of 322 cups of dirt are required to fill all 14 pots.

We need to multiply the numerator and denominator by 3-√5 to rationalize the denominator of the fraction. Therefore, the correct answer is option B

To rationalize the denominator of the fraction 6−2√3+√5, we need to eliminate any radicals present in the denominator. We can do this by multiplying both the numerator and denominator by an expression that will cancel out the radicals in the denominator.

In this case, we can observe that the denominator contains two terms with radicals: -2√3 and √5. To eliminate these radicals, we need to multiply both the numerator and denominator by an expression that contains the conjugate of the denominator.

The conjugate of the denominator is 6+2√3-√5, so we can multiply both the numerator and denominator by this expression, giving us:

(6−2√3+√5)(6+2√3-√5) / (6+2√3-√5)(6+2√3-√5)

Simplifying the numerator and denominator, we get:

(6 * 6) + (6 * 2√3) - (6 * √5) - (2√3 * 6) - (2√3 * 2√3) + (2√3 * √5) + (√5 * 6) - (√5 * 2√3) + (√5 * -√5) / ((6^2) - (2√3)^2 - (√5)^2)
