Step-by-step explanationLines m and n are parallel. Which of the other 5 named angles have a measure of 110°?
Press the hotspot for all that apply.
Answer:
2 and angle that is left of 5
Step-by-step explanation:
Angle 2 is vertical from 110, and vertical angles are congruent. From this, we can figure out that 2 and 3 (they're supplementary) are 70. Angles 5 and 3 are Alternate Interior Angles, and therefore must be congruent. The one to the left of 5 is supplementary to it, and therefore must be 110. Your answers are angle 2 and the angle that is left of 5.

The cross-section of a nuclear power plant's cooling tower is in the shape of a hyperbola. Suppose the tower has a base diameter of 204 meters and the diameter at its narrowest point, 40 meters above the ground, is 68 meters. If the diameter at the top of the tower is 136 meters, how tall is the tower?
The tower is about [ ] meters tall.
(Round to one decimal place as needed.)
The tower is about 40 meters tall.
How to solve for heightDistance between the foci = 2 * 34 = 68 meters
Distance from each focus to the vertex = 102 - 34 = 68 meters
(x^2 / 68^2) - (y^2 / 68^2) = 1
x = 68 meters
(68² / 68²) - (y²/ 68²) = 1
Solving for y, we get:
y² = 0, which implies y = 0
Since the origin is 40 meters above the ground, and the top of the tower is at y = 0, the height of the tower is:
Height = 40 meters
The tower is about 40 meters tall.

The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.
Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.
We have:
z₁ = 7(cos(577°) + i sin(577°))
Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.
From the given information, we have:
z₂ = 21(cos(-7°) + i sin(-77°))
To find the quotient, we divide z₁ by z₂:
z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]
Substituting the given values, we have:
z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]
= (7/21) * [cos(584°) + i sin(584°)]
The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

Dr. Green examines the effect of cognitive coping training on stress levels. She randomly assigns half of her sample to training in which they are taught to calm themselves down by thinking optimistically, and by making positive statement to themselves. The other half of the sample are not given the cognitive coping training. A survey is used to assess the stress levels of the study participants. What is her independent variable?
The correct answer is B. Cognitive coping training
Explanation:
In a research study or experiment, the independent variable can be identified by answering questions such as what is the variable the researcher manipulates? or which variable is expected to affect another?. In Dr. Green's study, the factor she is manipulating is cognitive coping training because half of the participants are exposed to this training, and the other half are not exposed.
Also, the purpose of this study is to "examine the effect of cognitive coping training on stress levels", which shows cognitive coping training is independent as this is not affected by other variables and it is expected it affects the second variable or stress level. According to this, her independent variable is cognitive coping training.

Find the area of a trapezoid with bases of 16 feet and 10 feet and a height of 3 feet. 39 ft2 78 ft2 240 ft2 480 ft2
Answer: 39 ft2
Step-by-step explanation:
The area of the trapezoid is 39 square feet.
To find the area of a trapezoid, you can use the formula:
Area = (1/2) × (base1 + base2) × height
Given that the bases of the trapezoid are 16 feet and 10 feet, and the height is 3 feet, we can substitute these values into the formula:
Area = (1/2) × (16 + 10) × 3
Area = (1/2) × 26 × 3
Area = (1/2) × 78
Area = 39 ft^2
Therefore, the area of the trapezoid is 39 square feet.

What is the turning point of the graph of f(x)=|x|+4?
We define the turning point on a graph as the point where the graph changes its behavior (it changes from decreasing to increasing, or from increasing to decreasing).
For the case of absolute value functions, the turning point is always on the vertex, and remember that for the general absolute value function:
f(x) = |x + a| + b
The vertex is at (-a, b).
Then in this case:
f(x) = |x| + 4
The vertex is at (0, 4), then we conclude that the turning point is at(0, 4), thus the correct option is the first one.

The differentiation of the given function f(x) = eˣ+6 is eˣ
What is differentiation?The derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus.
Given is function f(x) = eˣ+6, we need to find the derivative of this function,
f(x) = eˣ+6
f'(x) = d / dx (eˣ+6)
= d(eˣ)/dx + d(6)/dx
Since, 6 is a constant and derivative of a constant is zero,
d(eˣ)/dx + d(6)/dx = d(eˣ)/dx + 0
Now, when we differentiate eˣ, we get eˣ itself,

The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 1600 miles. What warranty should the company use if they want 94% of the tires to outlast the warranty?
Answer:
The warranty the company should use is of 57,520 mile.
Step-by-step explanation:
Let X denote the tread life of a particular brand of tire.
It is provided that, \(X\sim N(60,000, 1600^{2})\).
Also provided that the company wants 94% of the tires to outlast the warranty.
Let x denote the warranty .
That is, P (X > x) = 0.94.
⇒ P (X < x) = 0.06
⇒ P (Z < z) = 0.06
The corresponding value of z is -1.55.
*Use a z-table.
Compute the value of x as follows:
\(z=\frac{X-\mu}{\sigma}\\\\-1.55=\frac{x-60000}{1600}\\\\x=60000-(1.55\times 1600)\\\\x=57520\)
Thus, the warranty the company should use is of 57,520 mile.

How to identify the similar triangles.From the question, we have the following parameters that can be used in our computation:
The triangles ABC and DBE
These triangles have the following measures
Two similar corresponding sidesTwo equal corresponding anglesThis means that the triangles are similar by the SAS similarity theorem
How to find each measureUsing the SAS similarity theorem, we have the following equation
(x + 1)/12 = (x + 5)/15
Cross multiply the equation
15x + 15 = 12x + 60
So, we have
3x = 45
Divide by 3
x = 15
This means that
x + 1 = 15 + 1 = 16
x + 5 = 15 + 5 = 20

I'm pretty positive it would be 1050 by multiplying 50 and 20 and adding 50
The total number of seats in the auditorium are 2225.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that an auditorium has 50 rows of seats. The first row has 20 seats, the second row has 21 seats, the third row has 22 seats.
We can write the sequence as -
20, 21, 22, 23, 24, .......,
It is a arithmetic sequence. We can write the total number of seats in the auditorium as the sum of the terms of the sequence. We can write -
S{n} = (50/2)(2 x 20 + 49 x 1)
S{n} = 25(40 + 49)
S{n} = 25 x 89
S{n} = 2225

Sketch advertising firm charges $150 to design a full-color flyer and 12 cents per flyer to print the flyer. Rose's Sweet Shop spent $192 on the flyers for the grand opening. How many Flyers did she buy?
Answer:
210
Step-by-step explanation:
First, we keep $150 on the back of our minds(or our paper).
Second, we would assume that Rose's would've designed the flyer at $150, making us determine how much flyers they bought for the remaining $42.
($192 - $150 = $42)
Now that we know all of this, we can begin.
12 x 5 is 60, so 60 cents makes 1 dollar.
So for every dollar, they can make 5 flyers.
If we do 5 x 42, we'll get the answer of 210, which is the amount of flyers she bought!
