The term "angle of depression" describes the angle created by a horizontal line and the line of sight from the observer's eye to a location below their horizontal line of sight. It is often calculated by descending from the horizontal line.

The angle of depression is a term that is frequently used in discussions of observations or measurements involving objects that are below the observer's location in geometry and trigonometry.

We know that;

Tan 3 = x/140

x = 140 Tan 3

What is simplification of expression?

 The process of solving a math problem is simply known as simplifying an expression. In essence, you aim to write an expression as simply as you can when you simplify it. By the time you're done, you shouldn't have any more addition, subtraction, multiplication, or division to do. Making anything simpler is the definition of simplify. Reducing an expression, fraction, or mathematical problem to its simplest form is known as simplification. Using calculations and solving the problem makes it simple.

Here the given expressions are,

1) 5a-3a+2a

Step-by-step explanation:

Number of sides = 15 (counted and it was a pain the a*s)

The total measure of the exterior angle = 360

= 360/15

= 24 degree

Each angle is measured 24 degree

The sum of the exterior angles of the polygon shown in the image is: 360°.

Regardless of the number of sides or angles a polygon has, the sum of exterior angles of any polygon is always 360 degrees.

Thus, the polygon given has 15 sides, however, the sum of all its exterior angles will still give 360 degrees.

Therefore, the sum of the exterior angles of the polygon shown in the image is: 360°.

a) The probabilities for X = 0, 1, 2, and 3, and then summing them up, we find that P(X > 3) ≈ 0.019. b) The probability of zero successes is approximately 0.430. c) The length of an interval of time is 1.306 hours.

a) The time between arrivals of small aircraft is exponentially distributed with a mean of one hour. To find the probability that more than three aircraft arrive within an hour, we will use the Poisson distribution, where λ (lambda) represents the average number of arrivals per hour, which is 1 in this case. The probability formula is P(X > 3) = 1 - P(X ≤ 3), where X is the number of arrivals. Using the Poisson formula, we get:

P(X > 3) = 1 - [P(X=0) + P(X=1) + P(X=2) + P(X=3)]

Calculating the probabilities for X = 0, 1, 2, and 3, and then summing them up, we find that P(X > 3) ≈ 0.019.

b) To find the probability that no interval contains more than three arrivals in 30 separate one-hour intervals, we can use the binomial distribution. The probability of success (an interval with more than three arrivals) is 0.019 from part a), and the probability of failure (an interval with three or fewer arrivals) is 1 - 0.019 = 0.981. Using the binomial formula with n = 30 (number of intervals) and p = 0.981, we find the probability of zero successes (i.e., no interval with more than three arrivals) is approximately 0.430.

c) To determine the length of an interval of time (in hours) such that the probability that no arrivals occur during the interval is 0.27, we use the exponential distribution formula:

P(T > t) = e^(-λt), where T is the waiting time between arrivals, t is the time interval, and λ is the average number of arrivals per hour (1 in this case).

We want to find the value of t such that P(T > t) = 0.27. So:

0.27 = e^(-1 * t)

Taking the natural logarithm of both sides, we get:

ln(0.27) = -t

Solving for t, we find that t ≈ 1.306 hours.

Answer:

\(\Large \boxed{161\°}\)

Step-by-step explanation:

Adjacent angles in a parallelogram add up to 180 degrees.

m∠Q and m∠S add up to 180 degrees.

m∠Q + m∠S = 180

m∠Q + 19 = 180

Subtract 19 from both sides.

m∠Q + 19 - 19 = 180 - 19

m∠Q = 161

The volume of the rectangular prism is 386.1 cubic meters.

To find the volume of a rectangular prism, we need to multiply its length, width, and height. In this case, the length is 22 m, the width is 5.5 m, and the height is 3.1 m. Therefore, we can write:

Volume = length x width x height

Volume = 22 m x 5.5 m x 3.1 m

Volume = 386.1 cubic meters

Therefore, the volume of the rectangular prism is 386.1 cubic meters.

The required number of children and adults for sitting in the theater are 300 and 50 respectively.

A equation is supposed to be linear equation in two factors in the event that it is written as hatchet + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an a and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are straight equation in two factors.

Let be consider number of children be x and that of adults is y.

We have,

x + y = 350-------(1)

y = 350 - x

And 5x + 10y = 2000------------------(2)

Put value of y in equation (2)

5x + 10( 350 - x) = 2000

5x + 3500 - 10x = 2000

-5x = -1500

x = 300

Then

y = 350 - x = 350 - 300 = 50

Thus, There will be 300 children and 50 adults in the  theater .

16. We want to split the triangle and square. We know that the triangle is a right triangle because its linear pair is 90°, which makes it also 90°.

Because this is a rectangle, opposite sides are congruent. So now we have the side measures of 12, 17, 12, and 17.

Don't forget to add up the two areas for the total area of the whole figure.

17. We want to split the trapezoid and rectangle. This is a rectangle because it has four right angles.

Because this is a rectangle, opposite sides are congruent. So now we have the side measures of 20, 6, 6, and 20.

Now we can also prove that the bottom base of the trapezoid has a measure of 20 because of Reflexive Property.

Refer to the image below for the rest.

18. We want to split this hexagon into two rectangles. We know that they're rectangles because they have four right angles.

Remember, you can't assume that it's a square just because it looks like one. It is not to scale.

To find the length of the larger rectangle, we can add the separate measures of the side to find the total length.

Because it's a rectangle, we now have the measures of 12, 12, 18, 18.

Because the bottom side of the larger rectangle is 12 and the sum of both bottom sides of both rectangles is 18, that makes the bottom side of the second rectangle 6.

Because opposite sides of a rectangle are congruent, this rectangle is a square because it has four congruent sides and four right angles.

The growth factor that could be used to model the population will be 1.04. Then the correct option is D.

Consider the function:

y = a (1 ± r) ˣ

Where x is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is a plus sign, then there is exponential growth happening by r fraction or 100r %.

If there is a minus sign, then there is exponential decay happening by r fraction or 100r %.

The population is increasing by 4% per year.

Then the growth factor that could be used to model the population will be

Growth factor = (1 + 4%)

Growth factor = (1 + 0.04)

Growth factor = 1.04

The unit tangent vector t(t) of the given vector function r(t) = (3t, 1 + 2t^2, t^2) is obtained by dividing the derivative of r(t) by its magnitude. The derivative of r(t) is (3, 4t, 2t), and the magnitude of this vector is sqrt(9 + 20t^2). Therefore, t(t) = (3, 4t, 2t) / sqrt(9 + 20t^2).

The unit normal vector n(t) can be obtained by dividing the derivative of t(t) by its magnitude. The derivative of t(t) is (3, 4, 2t), and the magnitude of this vector is sqrt(25 + 4t^2). Thus, n(t) = (3, 4, 2t) / sqrt(25 + 4t^2).
