Answer:

3

Step-by-step explanation:

3 is the complete oposite of -1/3 in terms of slopes, therefore they are perpendicular to each other.

Based on the calculations, the value of number x is equal to 22.

In order to determine the value of x, we would translate the word problem into an algebraic expression.

For the expression, six less than twice a number x is given by:

2x - 6.

Next, we would equate it to 38:

2x - 6 = 38

2x = 38 + 6

2x = 44

x = 44/2

x = 22.

Given:

There are 5 numbers followed by 2 letters.

Solution:

To find the answer, we will have a plate number that consists of 5 numbers followed by 2 letters. In that 5 numbers, each place has 10 choices-from 0 to 9. It will be: 10 * 10 * 10 * 10 * 10 = 100,000 .

Now, for the letters, there are 26 letters in the alphabet. We have two places for the letters and each place have 26 choices-from A to Z that will give us: 26 * 26 = 676

We will now multiply the acquired data for both the numbers and letters to arrive at the correct answer.

100,000 * 676 = 67,600,000

There are 37,837,800 ways to distribute 15 distinguishable objects into five distinguishable boxes so that the boxes have one, two, three, four, and five objects in them, respectively.

We are trying to find the number of ways to distribute 15 distinguishable objects into five distinguishable boxes so that each box has 1, 2, 3, 4, and 5 objects in them, respectively.

We can use the formula for combination to solve this problem. The number of ways to distribute n distinct objects into r distinct boxes where the first box has k1 objects, the second box has k2 objects, ..., and the last box has kr objects is:

n! / (k1! * k2! * ... * kr!)

Where n! is the factorial of n, k1! is the factorial of k1 and so on.

In this case, we have 15 distinct objects and 5 distinct boxes where the first box has 1 object, the second box has 2 objects, the third box has 3 objects, the fourth box has 4 objects, and the fifth box has 5 objects.

So, the number of ways to distribute 15 distinguishable objects into five distinguishable boxes so that the boxes have one, two, three, four, and five objects in them, respectively is:

15! / (1! * 2! * 3! * 4! * 5!) = 15! / (1×2×6×24×120)

Answer:

112in^2

Step-by-step explanation:

area of square = 10*10

                        = 100in

area of triangle = (6*4)/2

                          = 12in

100+12= 112

area of shape = 112in

Answer:

The area of the figure is 112

Step-by-step explanation:

For area, you multiply length x width

For the triangle, you do HALF THE BASE x height

So for the square, it's fairly simple

10 x 10 = 100

For the triangle, it's a bit more complicated

So we know the length of the square is 10 inches

And we see a 6 inch mark at the top of the square, showing where the square ends and the triangle begins

So the base of the triangle is 10 - 6 = 4 inches

Also, the overall height of the figure is 16 inches, and the height of the square is 10 inches

So the height of the triangle is 16 - 10 = 6 inches

So 4 is the base of the triangle

And 6 is the height of the triangle

So we half 4, which gives us 2

2 x 6 = 12

The area of the triangle is 12

And we already determined that the area of the square is 100

100 + 12 = 112

The area of the whole figure is 112

tis  noteworthy that the picture above has a typo, is not YC, it should be YX.

the triangles are similar by AA, therefore

\(\cfrac{16}{8}=\cfrac{YX}{17}\implies 2=\cfrac{YX}{17}\implies 34=YX \\\\\\ \cfrac{16}{8}=\cfrac{30}{AC}\implies 2=\cfrac{30}{AC}\implies AC=\cfrac{30}{2}\implies AC=15\)

A percentage is a way to describe a part of a whole. The percentage decrease is 20%.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

One year, the population of a city was 358,000. Several years later it was 286,400. Therefore, the percentage decrease is,

Percentage decrease = (358,000-286,400)/(358,000) × 100% = 20%

Answer:

1/12

Step-by-step explanation:

To solve this expression, we need to remember that division should be done before multiplication or addition/subtraction.

So we first simplify the expression by dividing 1/2 by 6:

1/2 ÷ 6 = 1/2 × 1/6

Next, we multiply the two fractions by multiplying their numerators and denominators:

1/2 × 1/6 = (1 × 1)/(2 × 6) = 1/12

Therefore, the value of the expression 1/2 ÷ 6 is equal to 1/12.

When the increment operator precedes its operand, as

++num, the expression is in prefix mode.

When the increment or decrement operator is placed before the operand ( to the operand's left), the operator is being used in prefix mode.

A prefix is defined by specifying its name with the name= keyword, its optional short name with the sname= keyword, optional input names with iname=, and the keyword prefix.

During an assignment of one variable to other the prefix mode of increment and decrement first increments or decrements the variable's value then updated value of the variable is used in assignment.

Postfix mode on the other hand is when the increment or decrement operator is placed after the operand (or to the oper and's right) .

Pre-increment, (for example, ++n) increments the value first, and then performs the specified operation.

The volume enclosed by the torus is π^2/2.

To find the volume enclosed by the torus, we can use cylindrical coordinates.

First, let's sketch the torus. It is a donut-shaped object, with a hole in the middle. The radius of the hole is given by the parameter a, and the radius of the entire torus is given by the parameter b. In this case, we have

ρ = 10sin(ϕ)

This means that the radius of the torus varies with the angle ϕ. At ϕ = 0 and ϕ = π, the radius is 0, while at ϕ = π/2, the radius is 10.

Now, to find the volume enclosed by the torus, we need to integrate the volume element over the appropriate region. In cylindrical coordinates, the volume element is given by

dV = ρ dz dϕ dθ

where ρ is the radius, dz is the height, and dθ is the angle around the z-axis. In this case, we can assume that the torus is symmetric around the z-axis, so we only need to consider a quarter of the torus, from ϕ = 0 to ϕ = π/2 and from θ = 0 to θ = π/2.

The limits of integration for ρ, ϕ, and θ are:

0 ≤ ρ ≤ 10sin(ϕ)

0 ≤ ϕ ≤ π/2

0 ≤ θ ≤ π/2

Thus, the volume enclosed by the torus is given by:

V = ∭ dV = ∫∫∫ ρ dz dϕ dθ

V = ∫0^(π/2) ∫0^(π/2) ∫0^(10sinϕ) ρ dz dρ dθ dϕ

Solving this integral gives:

V = π^2/2

Therefore, the volume enclosed by the torus is π^2/2.

Here are the z-scores for the given Confidence Interval levels:1. 68% CI: The confidence interval corresponds to 1 standard deviation on each side of the mean.

Thus, the z-score for the 68% \(CI is ±1.00.2. 85% CI\): The confidence interval corresponds to 1.44 standard deviations on each side of the mean.

We can calculate the z-score using the following formula:\(z = invNorm((1 + 0.85)/2)z = invNorm(0.925)z ≈ ±1.44\)Note that invNorm is the inverse normal cumulative distribution function (CDF) which tells us the z-score given a certain area under the curve.3. 99% CI: The confidence interval corresponds to 2.58 standard deviations on each side of the mean.

The answer to this question depends on the speed of the car and the time it takes for the angle of depression to change from 20 degrees to 45 degrees.

Angle is an abstract concept in mathematics that describes the measure of rotation between two lines, or the amount of space between two lines that meet at a point. It is measured in degrees, with a full circle being equal to 360 degrees. Angles are essential for understanding shapes, as they help to define their boundaries and measure their area. Angles are also important in physics, as they help to determine the direction and magnitude of forces.

To calculate the distance the car travels, you would need to multiply the speed of the car by the time it takes to change the angle of depression.

The angle of depression is the angle between the horizontal line and the line of sight of the observer. When the angle of depression changes from 20 degrees to 45 degrees, the car must move closer to the observer in order for the angle of depression to increase. This means that the car must travel away from the observer in order to increase the angle of depression.

The speed of the car must be taken into account when calculating the distance it has traveled. If the car is traveling at a constant speed, then it will take longer to travel a longer distance. If the car accelerates or decelerates, then it will take less time to travel a given distance.

The distance the car has traveled can be calculated by multiplying the speed of the car by the time it takes for the angle of depression to change from 20 degrees to 45 degrees. This will give an estimate of how far the car has traveled, allowing Emilio to better understand the situation he is observing.

Answer:

Time to land on 11ft is 4.25 seconds

Step-by-step explanation:

Given

\(y = 300 - 16t^2\)

Required

Solve for t when height is 11ft

This implies that \(y = 11\)

So: substitute 11 for y in \(y = 300 - 16t^2\)

\(11 = 300 - 16t^2\)

Collect Like Terms

\(16t^2 = 300 - 11\)

\(16t^2 = 289\)

Express both sides as squares

\(4^2 * t^2 = 17^2\)

\((4t)^2 = 17^2\)

Take square roots of both sides (ignore negative)

\(4t = 17\)

Solve for t

\(t = \frac{17}{4}\)

\(t = 4.25\)

Hence, time to land on 11ft is 4.25 seconds

The exact values of the sine, cosine, and tangent of the angle 255° are -1/√2, 1/√2, and -1, respectively.

To find the exact values of the sine, cosine, and tangent of the angle 255°, we can use the identity that relates the trigonometric functions of an angle to the trigonometric functions of its complement.

By expressing 255° as the sum of 300° and -45°, we can determine the exact values of the trigonometric functions for the given angle.

We know that the sine, cosine, and tangent of an angle are periodic functions, repeating every 360 degrees. To find the exact values of the trigonometric functions for 255°, we can express it as the sum of 300° and -45°, where 300° is a multiple of 360°.

Since the sine, cosine, and tangent functions are odd or even functions, we can use the values of the trigonometric functions for 45° to determine the values for -45°.

For 45°:

sin(45°) = cos(45°) = 1/√2

tan(45°) = 1

Since cosine is an even function, cos(-45°) = cos(45°) = 1/√2.

Since sine is an odd function, sin(-45°) = -sin(45°) = -1/√2.

Using the definition of tangent as the ratio of sine to cosine, tan(-45°) = sin(-45°) / cos(-45°) = (-1/√2) / (1/√2) = -1.

Therefore, for the angle 255°:

sin(255°) = -1/√2

cos(255°) = 1/√2

tan(255°) = -1
