Answers

Answer:

k = 3

Step-by-step explanation:

2 - 6k = 5 - 3k -12

Add like terms at RHS

2 - 6k = -3k - 7

Add 6k to both sides

2 - 6k + 6k = -3k - 7 + 6k

2 = 3k - 7

Add 7 to both sides

2 +7 = 3k

9 = 3k

Divide both sides by 3

9/3 = 3k/3

3 = k

k  = 3

Answer:

LM is 8

Step-by-step explanation:

LM --> (2x-16)+(x-9) =11

Solve for x

2x+x-16-9 =113x-25=113x=36x=12

Plug in this value for LM equation to solve for LM:

A pendulum swinging through a central angle of 108° completes an arc of length 24 cm. What is the length of the
pendulum? Round to the nearest hundredth.

Answers

Answer:

Yes! I was looking to refresh my geometry skill!

Step-by-step explanation:

So, a 108* arc is 24 cm. How to solve it?

First, we need to find the Circumference, or perimeter of the circle. (That the swinging pendulum makes.

Second, use that in the formula for circumference, and find the radius.

Third, done! So, let's get to it!

All we have to do to find the circumference is divide 24 by 108, then multiply that by 360*(because a circle is 360*).

[tex]24/108*360=80[/tex]

So, our circumference is 80cm. Nice! Just need to input that into the circumference formula.

[tex]80=2\pi *r\\[/tex]

Now, to solve...

[tex]40=\pi *r\\40/\pi =r[/tex]

This rounds to about 12.73 cm.

Hope this helps!

Identify which line from the graph the following right triangles could lie on.

Answers

Answer:

Step-by-step explanation:

Slope of line A = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                         = [tex]\frac{9}{3}[/tex]

                         = 3

Slope of line B = [tex]\frac{9}{6}[/tex]

                         = [tex]\frac{3}{2}[/tex]

Slope of line C = [tex]\frac{6}{8}[/tex]

                         = [tex]\frac{3}{4}[/tex]

5). Slope of the hypotenuse of the right triangle = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                                                                                = [tex]\frac{90}{120}[/tex]

                                                                                = [tex]\frac{3}{4}[/tex]

Since slopes of line C and the hypotenuse are same, right triangle may lie on line C.

6). Slope of the hypotenuse = [tex]\frac{30}{10}[/tex]

                                              = 3

Therefore, this triangle may lie on the line A.

7). Slope of hypotenuse = [tex]\frac{18}{24}[/tex]

                                        = [tex]\frac{3}{4}[/tex]

Given triangle may lie on the line C.

8). Slope of hypotenuse = [tex]\frac{21}{14}[/tex]

                                        = [tex]\frac{3}{2}[/tex]

Given triangle may lie on the line B.

9). Slope of hypotenuse = [tex]\frac{36}{24}[/tex]

                                        = [tex]\frac{3}{2}[/tex]

Given triangle may lie on the line B.

10). Slope of hypotenuse = [tex]\frac{48}{16}[/tex]

                                          = 3

Given triangle may lie on the line A.

Tutoring Services: Suppose that 40% of community college students never use tutoring services available at their college. Suppose we randomly select samples of community college students. For each sample we calculate the proportion who do not use tutoring. If we randomly sample 500 students at a time, what will be the mean and standard error of the sampling distribution of sample proportions

Answers

Answer: The mean and standard error of the sampling distribution of sample proportions are 0.40 and 0.0219 respectively.

Step-by-step explanation:

Formula : Mean  of the sampling distribution of sample proportions

[tex]\mu_p= p[/tex]

Standard error of the sampling distribution of sample proportions

[tex]\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}[/tex]

, where p = population proportion

n= sample size

Here, p =0040

n= 500

So , Mean  of the sampling distribution of sample proportions

[tex]\mu_p= 0.40[/tex]

Standard error of the sampling distribution of sample proportions

[tex]\sigma_p=\sqrt{\dfrac{0.40(1-0.40)}{500}}\\\\=\sqrt{\sdfrac{0.40\times0.60}{500}}\\\\=\sqrt{\dfrac{0.24}{500}}\\\\=\sqrt{0.00048}\\\\\approx0.0219[/tex]

Hence, mean and standard error of the sampling distribution of sample proportions are 0.40 and 0.0219 respectively.

An owner of a home in the Midwest installed solar panels to reduce heating costs. After installing the solar panels, he measured the amount of natural gas used y (in cubic feet) to heat the home and outside temperature x (in degree-days, where a day's degree-days are the number of degrees its average temperature falls below 65° F) over a 23-month period. He then computed the least-squares regression line for predicting y from x and found it to be ŷ = 84 + 18x. How much, on average, does gas used increase for each additional degree-day?

Answers

Answer:

18

Step-by-step explanation:

In the linear regression equation y=a+bx, slope coefficient b represents average unit increases in y variable due to unit increase in x variable.

In the given equation ŷ = 84 + 18x, b=18 represents average unit increases in gas used due to unit increase in degree day.

Hence,on average,  gas used increase by 18 for each additional degree-day.

An airplane flies at an altitude of 14,690 ft while a submarine is submerged at a depth of 521 feet below the surface of the ocean.. What is the difference between these two elevations? Write an algebraic expression for the given applied problem. Simplified the algebraic expression. In the context of the applied problem, explain what your simplified algebraic expression represents.

Answers

Answer:

[tex]d_{T} = d_{A}-d_{S}[/tex]. The algebraic equation represents the distance of the airplane with respecto to the submarine. The distance between the two elevations is 15211 feet.

Step-by-step explanation:

Let be [tex]d[/tex] the distance between a vehicle and sea level, [tex]d > 0[/tex] when vehicle is above sea level, otherwise is below sea level. The difference between airplane and submarine ([tex]d_{T}[/tex]), measured in feet, is obtained by the following expression, that is:

[tex]d_{T} = d_{A}-d_{S}[/tex]

Where:

[tex]d_{A}[/tex] - Distance of airplane with respect to sea level, measured in meters.

[tex]d_{S}[/tex] - Distance of submarine with respect to sea level, measured in meters.

If we know that [tex]d_{A} = 14690\,ft[/tex] and [tex]d_{S} = -521\,ft[/tex], then:

[tex]d_{T} = 14690\,ft - (-521\,ft)[/tex]

[tex]d_{T} = 15211\,ft.[/tex]

The algebraic equation represents the distance of the airplane with respecto to the submarine. The distance between the two elevations is 15211 feet.

The algebraic equation represents the distance of the airplane with respect to the submarine is,

[tex]\rm The \ difference \ between \ both \ elevation = x_a- x_s[/tex]

And the distance between the two elevations is 15,211 feet.

Given that,

An airplane flies at an altitude of 14,690 ft,

While a submarine is submerged at a depth of 521 feet below the surface of the ocean.

We have to determine,

What is the difference between these two elevations?

According to the question,

Let, x be the distance between a vehicle and sea level when the vehicle is above sea level, otherwise is below sea level.

The difference between an airplane [tex]\rm x_a[/tex] and [tex]\rm x_s[/tex] a submarine, measured in feet, is obtained by the following expression, that is:

[tex]\rm The \ difference \ between \ both \ elevation = x_a- x_s[/tex]

Where [tex]\rm x_a[/tex] represents the distance of airplane with respect to sea levels.

And [tex]\rm x_s[/tex] represent the distance of the submarine with respect to sea levels.

Submerged at a depth of 521 feet below the surface of the ocean,

[tex]\rm x_s = -521 \ feet[/tex]

Therefore,

The difference between an airplane [tex]\rm x_a[/tex] and [tex]\rm x_s[/tex] a submarine is,

[tex]\rm The \ difference \ between \ both \ elevation = x_a- x_s\\\\ The \ difference \ between \ both \ elevation = 14,690-(-521)\\\\\rm The \ difference \ between \ both \ elevation = 15,211 \ feet[/tex]

Hence, The difference between these two elevations is 15,211 feet.

A piece of land is shaped like a right triangle. Two people start at the right angle at the same time, and walk at the same speed along different legs of the triangle while spraying the land. If the area covered is changing at
5 m2/s, how fast are the people moving when they are 5 m from the right angle? (Round approximations to two decimal places.)

Answers

Answer:

1 m/s

Step-by-step explanation:

the area of the triangle = A = ¹/₂ab

where a is the distance covered by the first person and b is the distance covered by the second person. since they walk at the same speed, then a = b, so our formula can be changed to A = ¹/₂x²

now we find the derivative of both sides:

dA/dt = ¹/₂ ⋅ dx²/dt

dA/dt = ¹/₂ ⋅ 2x ⋅ dx/dt

dA/dt = x ⋅ dx/dt = x ⋅ velocity

we are told that x = 5 m, and dA/dt = 5 m²/s

velocity = dA/dt / x

velocity = 5 m²/s / 5 m = 1 m/s
