Answer:

Radius AB = 9.3 units

Step-by-step explanation:

Given:

BC (tangent) make right angle with radius AB.

AC = 16 units

BC = 13 units

Find:

Radius AB = ?

Computation:

Using Pythagoras theorem:

[tex]Hypotenuse^2 = Perpendicular^2 +Base^2\\\\AB =\sqrt{AC^2 -BC^2}\\\\ AB =\sqrt{16^2 -13^2}\\\\AB =\sqrt{256 -169}\\\\AB =\sqrt{87}\\\\AB =9.327[/tex]

Radius AB = 9.3 units

The question lacks clear context for the radius calculation, but assuming AC and BC are sides of a right triangle with the hypotenuse as the diameter of a circle, the radius can be found using the Pythagorean theorem. The calculated radius would be approximately 10.307764.

The question seems to be asking for the radius of a circle given certain measurements from a triangle. However, the information provided is ambiguous as it lacks context and specifics such as which geometric scenario we are dealing with. Nonetheless, assuming that AC and BC are legs of a right triangle, and if the hypotenuse is the diameter of a circle, we can calculate the radius using the Pythagorean theorem.

To find the radius (R), we would expect to have a right triangle with sides AC and BC, and a hypotenuse that is twice the radius. However, the lengths given in the question (AC=16 and BC=13) do not correspond to one of the formulae provided which suggests using the lengths in a Pythagorean relationship. Instead, if these lengths are for a right-angled triangle, we would calculate the hypotenuse as follows:

√(AC² + BC²) = √(16² + 13²) = √(256 + 169) = √425 ≈ 20.615528

Therefore, if the hypotenuse is the diameter of the circle, the radius R would be approximately half of this value, or 10.307764.

Answer:

D. Undefined

Step-by-step explanation:

The line is a vertical line.

Vertical lines have undefined slopes

Answer:

Undefined

Step-by-step explanation:

Vertical lines will always have undefined slopes. This is a vertical line because it is straight up and down.

To make sure, we can test 2 points: (2,1) and (2,2) in the slope formula

y2-y1/x2-x1

2-1/2-2

1/0

It is impossible to divide by 0, so the slope is undefined.

Answer:

4.46

Step-by-step explanation:

As the circumference of a circle is pi multiplied by the diameter to work out the radius you would first divide the circumference of 28 by pi, which gives you 8.92. This is the diameter, however the question is asking for the radius. To work out the radius you would divide the diameter by 2, which gives you 4.46. This is because the radius is half of the diameter.

1) Divide 28 by pi.

[tex]28/\pi =8.92[/tex]

2) Divide 8.92 by 2.

[tex]8.92/2=4.46[/tex]

-The answer for the radius:

[tex]\sqrt{61} = r[/tex]

Step-by-step explanation:

-The equation of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex] (where the center is known as [tex](h,k)[/tex], the point is [tex](x,y)[/tex] and the radius known as [tex]r[/tex]).

-Use both the center (-2,-1) and the point (-7,-7) for the equation:

[tex](-7+2)^2+(-7+1)^2=r^2[/tex]

-Then, solve the equation to get the radius:

[tex](-7+2)^2+(-7+1)^2=r^2[/tex]

[tex](-5)^2+(-6)^2=r^2[/tex]

[tex]25+36=r^2[/tex]

[tex]61 = r^2[/tex]

[tex]\sqrt{61} = \sqrt{r^2}[/tex]

[tex]\sqrt{61} =r[/tex]

So, therefore the radius is [tex]\sqrt{61}[/tex] .

Answer:

To the nearest hundredth : 628.32 [tex]cm^2[/tex]

To the nearest whole number : 628 [tex]cm^2[/tex]

Step-by-step explanation:

The formula for the area of a circle is : [tex]\pi*radius^2[/tex]

To work out the area you would first need to work out the radius. You can do this by dividing the diameter of 40 cm by 2, this gives you 20 cm. This is because the radius is half of the diameter.

Now that we have worked out the radius, the next step would be to work out the area. You can do this by multiplying pi by the radius of 20 squared, this gives you 1256.64.

The final step is to work out the area of this semi-circle. You can do this by dividing the area of 1256.64 by 2, this gives you 628.32 [tex]cm^2[/tex]. This is because a semi-circle is half of a circle.

1) Divide 40 by 2.

[tex]40/2=20 cm[/tex]

2) Multiply pi by 20 squared.

[tex]\pi*20^2=1256.64 cm^2[/tex]

3) Divide 1256.64 by 2.

[tex]1256.64/2=628.32 cm^2[/tex]

The area of the semicircle is approximately 628 square centimeters.

To find the area of a semicircle with a given diameter, we need to use the formula for the area of a circle and then divide it by 2, since a semicircle is half of a circle.

The formula for the area of a circle is:

[tex]\[ A = \pi r^2 \][/tex]

where [tex]\( r \)[/tex] is the radius of the circle. Given the diameter is 40 cm, we can find the radius by dividing the diameter by 2:

[tex]\[ r = \frac{40 \, \text{cm}}{2} = 20 \, \text{cm} \][/tex]

Now, we can calculate the area of the full circle:

[tex]\[ A_{\text{circle}} = \pi (20 \, \text{cm})^2 = 400\pi \, \text{cm}^2 \][/tex]

Since the semicircle is half of the full circle, the area of the semicircle is:

[tex]\[ A_{\text{semicircle}} = \frac{1}{2} A_{\text{circle}} = \frac{1}{2} \times 400\pi \, \text{cm}^2 = 200\pi \, \text{cm}^2 \][/tex]

Using [tex]\(\pi \approx 3.14159\)[/tex]

[tex]\[ A_{\text{semicircle}} \approx 200 \times 3.14159 \, \text{cm}^2 \approx 628.32 \, \text{cm}^2 \][/tex]

Rounding to the nearest whole number:

[tex]\[ A_{\text{semicircle}} \approx 628 \, \text{cm}^2 \][/tex]

Answer:

120 pixels wide by 70 pixels high

Step-by-step explanation:

Think about it...

The image is 600/350

that is equivalent to 12/7 or 7:12

The space provided is 120/70

that is equivalent to 12/7 or 7:12

Since the ratios are the same the largest possible size the image can be is 120/70

The largest image of the school mascot that will fit in the web page is 120 pixels wide by 70 pixels high, which is the same aspect ratio as the original image size of 600 pixels wide by 350 pixels high.

Your task is to determine the biggest possible size for the school mascot image on the school web page. The spot for the mascot on the webpage is restricted to 120 pixels wide by 70 pixels high, while the actual digital image is 600 pixels wide by 350 pixels high.

The image needs to keep its aspect ratio (the ratio of width to height) in order to prevent distortion. The aspect ratio of the digital image is 600/350 (or 60/35 when simplified), which equals 12/7. Therefore, the mascot image also needs to have a 12/7 ratio to fit in the webpage space perfectly.

The way to do this is to scale down the image. Scaling works equally on both width and height of the image, therefore, we can start by scaling down the width from 600 pixels to 120 pixels. To calculate the scale factor, we divide 120 (the width of the webpage space) by 600 (the width of the image). The scale factor is 0.2 or 20%.

Applying this scale factor to the height: Scale factor * height of image = 0.2 *350 = 70 pixels, which is exactly the height of the webpage space. So, the largest image of the mascot that will fit in the webpage is 120 pixels wide by 70 pixels high, which maintains the same aspect ratio as the digital image.

Answer: The surface area for this cylinder is 252*pi square inches.

Step-by-step explanation:

The surface area of a cylinder can be calculated by using the following formula:

surface area = 2*pi*r² + 2*pi*r*h

Applying the data from the problem, we have:

surface area = 2*pi*(6)² + 2*pi*(6)*15

surface area = 2*pi*36 + 180*pi

surface area = 72*pi + 180*pi

surface area = 252*pi

The surface area for this cylinder is 252*pi square inches.

Step-by-step explanation: edge 2021

The surface area of the cylinder, given h = 15 inches and r = 6 inches, is 252π square inches.

To find the surface area (SA) of a cylinder, we use the formula [tex]\(SA = 2\pi r^2 + 2\pi rh\)[/tex], where r is the radius and h is the height. Given h = 15 inches and r = 6 inches, we substitute these values into the formula:

[tex]\[SA = 2\pi(6)^2 + 2\pi(6)(15)\][/tex]

[tex]\[SA = 2\pi(36) + 2\pi(90)\][/tex]

[tex]\[SA = 72\pi + 180\pi\][/tex]

[tex]\[SA = 252\pi\][/tex]

Thus, the surface area of the cylinder is 252π square inches. This includes the areas of the two circular bases and the lateral surface area formed by the curved surface.

rate of return is 22%

Step-by-step explanation:

The it would take for mutual to double can be determined the future value formula as shown below:

=nper(rate,pmt,-pv,fv)

rate is the rate of return of 7% per year

pmt is the periodic amount placed in the mutual fund and it not applicable here

pv is the original amount invested which is $7,500

fv is the future worth of $15,000

=nper(7%,0,-7500,15000)=10.2 years

cost of shares=actual cost of purchase+broker's commission

                      =(800*$15.34)+$20=$12,292.00  

gain on shares=sales proceeds-cost=(800*$18.77)-$20-$12,292.00=$2,704.00  

rate of return=gain/original cost=$2,704.00/$12,292.00  =22%

You know this because you're familiar with the first few Pythagorean triples:

   (3, 4, 5), (5, 12, 13), (7, 24, 25), ...

If you're not, you can use the Pythagorean theorem to check. The sides will form a right triangle if and only if they satisfy the Pythagorean theorem.

  13^2 = 12^2 +5^2

  169 = 144 + 25 . . . . . . true

Your knowledge of numbers tells you that these numbers cannot satisfy the Pythagorean theorem.* The sum of an even and and odd number cannot be even. (The square of a number has the same parity as the number itself.)

* Thanks to Brainly, I recently figured out that you can apply a parity test to candidates for right triangle sides. The number of odd-length sides must be even. There cannot be a right triangle with integer side lengths, only one of which is odd.

The mean, median, and mode of the weekly salaries at the Midtown Construction Company are provided. We can use this information to answer questions about the percentage of salaries surpassing certain values and the total salary of all employees.

To answer the question, we need to understand what each statistical term means.

The mean is the average of a set of numbers. In this case, the mean salary is $620.

The median is the middle value of a set of numbers when they are arranged in ascending order. In this case, the median salary is $610.

The mode is the value that appears most frequently in a set of numbers. In this case, the mode salary is $600.

Now, let's answer the questions:

c. To find the percentage of employees' salaries that surpassed $645, we need to calculate the percentage of values that are greater than $645 in the data set. Since the third quartile is $645, we know that 75% of the salaries are less than or equal to $645. Therefore, about 25% of the salaries surpassed $645.

d. To find the percentage of employees' salaries that surpassed $685, we need to calculate the percentage of values that are greater than $685 in the data set. Since the 85th percentile is $685, we know that 85% of the salaries are less than or equal to $685. Therefore, about 15% of the salaries surpassed $685.

e. To find the total weekly salary of all employees, we need to multiply the mean salary ($620) by the number of employees (100). Therefore, the total weekly salary of all employees is $62,000.

Step-by-step explanation:

First find the total and then establish probability for each color: 2+5 = 7 total marbles. [tex]\frac{2}{7}[/tex] for blue and [tex]\frac{5}{7}[/tex] for red. Because you don't replace the marble you took out the total will do down one but the number of blue will not be affected to it just changed from [tex]\frac{2}{7} to \frac{2}{6}[/tex]

On part b I'm a little confused, are you putting a blue marble in the bag and then finding red's probability? If so, you are in theory replacing the first red marble so the total will be 7 again but since it's a blue marble your probabilities change to [tex]\frac{3}{7}[/tex] for blue and [tex]\frac{4}{7}[/tex] for red.
