slope of the image?

Answer:

Step-by-step explanation:

the problem that would have to be plugged into the calculator would be as following

[tex]\cfrac{31\pi }{4}\implies \cfrac{8\pi +8\pi +8\pi +4\pi +3\pi }{4}\implies 2\pi +2\pi +2\pi +\pi +\cfrac{3\pi }{4}[/tex]

so the angle θ  is really 3 revolutions plus π and then a little bit more, Check the picture below for the red reference angle.

Answer:

  63.0°

Step-by-step explanation:

You want the measure of an angle in a right triangle with hypotenuse 11 and adjacent side 5.

The cosine relation is ...

  Cos = Adjacent/Hypotenuse

  cos(x) = 5/11

Then the angle is found using the inverse cosine function:

  x = arccos(5/11) ≈ 63.0°

The value of x is about 63.0°.

Additional comment

The calculator's angle mode needs to be set to "degrees."

Hence, x=-2 and y=4 are the answers to the system of equations.

For the purpose of connecting algebra and geometry with the aid of line and curve graphs, coordinate geometry is necessary. Finding points on a plane is a crucial component of mathematics. It also has a number of uses in other scientific fields such dimensional geometry, calculus, and trigonometry. Use y=-2x in place of x in the first equation:

5x - 9(-2x) = -46

Simplify and find x's value:

5x + 18x = -46

23x = -46

x = -2

We can use the second equation to get y now that we know the value of x:

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

Answer:

The pilot was scheduled to depart at 4:00 p.m.

Her departure has been delayed by 16 minutes.

Air traffic control approved a new flight plan that will allow her to arrive four times faster than she calculated in her original flight plan.

We want to create an equation that can be used to predict the number of minutes after 4:00 p.m. she will arrive at her destination.

First, let's represent the time of her original flight as x, in minutes. This means that her original flight plan would have taken x minutes to arrive at her destination.

However, with the new flight plan approved by air traffic control, she will arrive four times faster than she calculated in her original flight plan. This means that her new flight plan will take x/4 minutes to arrive at her destination.

Now, we need to take into account the 16-minute delay in her departure. This means that she will depart at 4:16 p.m. instead of 4:00 p.m., and therefore arrive at her destination x/4 minutes after 4:16 p.m.

So the equation that can be used to predict the number of minutes after 4:00 p.m. she will arrive at her destination is:

Number of minutes after 4:00 p.m. = 16 + x/4

Note that this equation assumes that her flight time is the only factor affecting her arrival time, and does not take into account any other delays or factors that may affect her flight.

The sides of the triangle in order from shortest to longest are b < a < c

In triangle ABC, the side opposite angle A is denoted by a,

To determine the order of the sides from shortest to longest, we need to use the triangle inequality theorem which implies that

The side opposite the largest angle is the largest side and vice versa

So, we have

b from B = 38 degrees

a from A = 54 degrees

c from C = 88 degrees

Therefore, the order of the sides from shortest to longest is: b < a < c

In other words, the side opposite angle B is the shortest, followed by the side opposite angle A, and the side opposite angle C is the longest.

the average nicotine content of one kind of cigarette exceeds that of another kind by 0.20 milligram at the 0.05 level of significance.

To test the hypothesis that the average nicotine content of one kind of cigarette exceeds that of another kind by 0.20 milligram, we need to compare the means of two independent samples. We can use a two-sample t-test for this purpose. The null hypothesis is that the difference between the means is equal to 0.20 milligram, and the alternative hypothesis is that it is not equal to 0.20 milligram.

The test statistic is given by:

t = ([tex]x_{1}[/tex] - [tex]x_{2}[/tex] - d) / [tex]\sqrt{s_{1}^{2}/n_{1}+s_{2}^{2}/n_{2} }[/tex]

where x1 and x2 are the sample means, s1 and s2 are the sample standard deviations, n1 and n2 are the sample sizes, and d is the hypothesized difference in means (0.20 milligram in this case).

Substituting the given values, we have:

x1 = 2.61 milligrams

[tex]x_{1}[/tex] = 2.38 milligrams

[tex]s_{1}[/tex] = 0.12 milligram

[tex]s_{2}[/tex] = 0.14 milligram

n1 = 50 cigarettes

n2 = 40 cigarettes

d = 0.20 milligram

t = (2.61 - 2.38 - 0.20) / [tex]\sqrt{0.12^{2}/50+0.14^{2}/40 }[/tex]= 4.57

The degrees of freedom for the test are given by:

[tex]df= (s_{1}^{2} /n_{1} +s_{2}^{2}/n_{2})^{2}/(s_{1}^{2} /s_{1})^{2}/_{1}-1 +(s_{2}^{2}/n_{2}^{2} /n_{2}-1[/tex])

Substituting the given values, we have:

df = [tex]( 0.12^{2}/50+0.14^{2}/40)^{2}/((0.12^{2}/50)^{2}/49+(0.14^{2}/40)^{2}/39= 86.36[/tex](rounded to two decimal places)

Using a t-distribution table or a calculator, we can find the critical values for a two-tailed test at the 0.05 level of significance with 86 degrees of freedom. For a two-tailed test, the critical values are ±1.987.

Since the calculated t-value of 4.57 is greater than the critical value of 1.987, we reject the null hypothesis.

The sample sizes for the two universities need to be identical in order for their sampling distributions to have about the same standard deviation.

A sampling distribution is a probability distribution that specifies how a statistic—like the mean or standard deviation—behaves when it is generated from population-based samples of a specific size. It is crucial to statistical inference because it makes it easier to calculate the likelihood of receiving specific sample statistics from a population and to draw conclusions about the characteristics of the population from the sample data. The population factors and sample size both have an impact on the form, centre, and spread of a sampling distribution.

The size of the sample for the sampling distributions is given as:

n1 = (s1 / s2) * n2

where n1 and n2 are the sample sizes for College A and College B respectively.

We may assume that the variances of the two populations are identical as we want the sampling distributions to have about the same standard deviation. As a result, we may make the formula as follows by setting s1 = s2:

n1 = n2

We may draw the conclusion that the sample sizes for the two universities need to be identical in order for their sampling distributions to have about the same standard deviation.

The two points on the line to graph the function is (3, 4/3) and (-6, 10/3).

A line is a one-dimensional, straight shape that can go on forever in both directions. It is made up of an infinite number of points that are organized in a straight line.

We are unable to offer two points on the line for graphing in the absence of a line or function.

We consider the function is, [tex]f(x) = 2 - \frac{2}{9} x[/tex]

To graph the function [tex]f(x) = 2 - \frac{2}{9} x[/tex] , we can choose any two values of x, plug them into the equation to find the corresponding values of y, and then plot the points (x, y) on the coordinate plane. Here are two possible sets of points we can use:

Set 1:

Let x = 0:

f(0) = 2 - (2/9)(0) = 2

Therefore, one point on the line is (0, 2).

Let x = 9:

f(9) = 2 - (2/9)(9) = 0

and another point on the line is (9, 0).

Now, we can plot these two points on the coordinate plane and draw a straight line passing through them to graph the function [tex]f(x) = 2 - \frac{2}{9} x[/tex]

Set 2:

Let x = 3:

f(3) = 2 - (2/9)(3) = 2 - (2/3) = 4/3

So one point on the line is (3, 4/3).

Let x = -6:

f(-6) = 2 - (2/9)(-6) = 2 + (4/3) = 10/3

So another point on the line is (-6, 10/3).

Now, we can plot these two points on the coordinate plane and draw a straight line passing through them to graph the function [tex]f(x) = 2 - \frac{2}{9} x[/tex]

Therefore, the two points on the line to graph the function is (3, 4/3) and (-6, 10/3).

2/4 = 0.5

To find the length of blue rectangle 2 in relation to the width of green rectangle 6, we need to divide the length of blue rectangle 2 by the width of green rectangle 6.

So, the length of blue rectangle 2 to the width of green rectangle 6 is:

2/6 = 0.33 (rounded to two decimal places)

Note that the ratio of the length of blue rectangle 2 to the length of green rectangle 4 is different from the ratio of the length of blue rectangle 2 to the width of green rectangle 6.

The distance travelled in the first 14 seconds would then be 3.57 x 14 = 49.98 metres.the acceleration would be 7.14 - 3.57 = 3.57 metres per second squared.

Distance is the numerical measurement of how far apart two objects are. It is measured in units such as kilometers, meters, miles, feet, inches, and more. Distance can be calculated in one, two, or three dimensions. Distance is a key factor in many real-world applications, such as navigation, transport, and communication. Distance can also be used to describe relationships, such as the connection between two people.

A)To work out the distance travelled on a cycle in the first 14 seconds, we must first determine the velocity of the cycle. This can be done by dividing the distance travelled by the time taken. For example, if the cycle travelled 50 metres in 14 seconds, the velocity would be 50 / 14 = 3.57 metres per second. The distance travelled in the first 14 seconds would then be 3.57 x 14 = 49.98 metres.

B) To work out the acceleration speed in the first 4 seconds, we must first determine the change in velocity over the period of time. We can do this by subtracting the initial velocity from the final velocity. For example, if the cycle started at a velocity of 3.57 metres per second, and increased to 7.14 metres per second after 4 seconds, the acceleration would be 7.14 - 3.57 = 3.57 metres per second squared.

The answer is C

The y-coordinate value of Point C if the area of ABC is 9 units squared is: 5 or -1

Point A is at (x, 2) and B is at (x + 6, 2). Since AB must lie on the line y=2  and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).

Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).

The area of ΔABC is 9. So,

9 = 1/2 (b)(h)

where b is the base and h is the height.

so b = 6 and h = AC

Solving this for AC gives

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.

If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.

Therefore, y-coordinate is 5 or -1.

The total surface area of the triangular prism is 556 square units.

Step-by-step explanation:

The given 3D figure is a triangular prism.

The formula to find the total surface area of a triangular prism is:

[tex]\boxed{\textsf{Total Surface Area}= \sf 2 A_B+(a+b+c)h}[/tex]

where:

Therefore, the surface area of a triangular prism is the sum of the area of two congruent triangular bases and three rectangles.

The area of a triangle can be calculated by halving the product of the length of its base and height.  

The base of the triangles is 17 units and the height is 8 units.

Therefore, the area of each triangular base is:

[tex]\begin{aligned}\implies \sf Area\;of\;triangular\;base\;(A_B)&=\sf\dfrac{1}{2} \cdot17 \cdot8\\&=\sf 68\;square\;units\end{aligned}[/tex]

Therefore, the values to substitute into the total surface area formula are:

[tex]\begin{aligned}\implies \textsf{Total Surface Area}&= \sf 2 A_B+(a+b+c)h\\&= \sf 2 (68)+(11+14+17)10\\&=\sf 2 \left(68\right)+(42)10\\&=\sf 136+420\\&=\sf 556 \; square\;units\end{aligned}[/tex]

Therefore, the total surface area of the given triangular prism is 556 square units.
