The answer is 32.13 kilometers

please see the attached picture for full solution

Hope it helps

Good luck on your assignment

Answer:

\(32.13km\)

Step-by-step explanation:

First find the arc length of

\( \frac{90}{360} \times2 \pi r \\ \frac{1}{4} \times 3.14 \times 9 \times 2\\ = \frac{254.34}{4} \\ = 14.13km\)

Now let's find the perimeter

\(perimeter = arc \: \: length + radius + radius \\ 14.13km + 9 + 9 \\ =32.13km \)

Answer:

1  \(\mu = 100\)

2 \(\sigma = 16\)

3 \(\mu_x = 100\)

4 \(\sigma _{\= x } = 2.309\)

Step-by-step explanation:

From the question

    The population mean is  \(\mu = 100\)

    The standard deviation is \(\sigma = 16\)

     The sample mean is  \(\mu_x = 100\)

     The sample size is  \(n = 48\)

     The mean standard deviation is  \(\sigma _{\= x } = \frac{\sigma }{\sqrt{n} }\)

substituting values

     \(\sigma _{\= x } = \frac{16 }{\sqrt{48} }\)

     \(\sigma _{\= x } = 2.309\)

\(\dfrac{3x^4+11x^3-24x^2-15x+25}{x+5} = \boxed{3x^3-4x^2-4x+5}\)

Answer:

B: sometimes

Step-by-step explanation:

Let's look at two examples.

Example A.

2, 3, 5: mean is 3

Replace 5 with 1. Now you have 1, 2, 3: mean is 2.

In this case, it affected the mean.

Example B.

2, 3, 5: mean is 3

Replace 5 with 4. Now you have 2, 3, 4: mean is 3.

In this case, it did not affect the mean.

As you can see, replacing the maximum value of the data set with a smaller number may or may not change the mean.

Answer: B: sometimes

The cosine equation of the function shown is f(x) = 4cos(x) + 3

From the question, we have the following parameters that can be used in our computation:

The graph

From the graph, we can see that the function is shifted up

Next, we enter the points in a graphing calculator to determine the function

From the graph, we have

f(x) = 4cos(x) + 3

Hence, the equation is f(x) = 4cos(x) + 3

Step-by-step explanation:

For number 2, you take the amount of cookies, x, and divide it by the number of hours, a, and you get x / a = 12.25 or 12.6

For number 3, you do the same as in number 2, you take the pages read, x, divided by the time, a, and get x / a = s

c 0.561

Step-by-step explanation:

did the test on edge

The probability that more than 30% of the owners in the sample pay for someone to walk their dog is option c. 0.561.

Since 31% of dog owners pay for someone to walk their dogs. Morgan asks a random sample of 50 dog

So

= P> ( 0.30 - 0.31) / √0.31 (1 - 0.31)/ 50

= P(z > - 0.1530)

= 0.5608

= 0.561

Answer:

Surface area of the box is 3345cm^2

Step-by-step explanation:

First you need to find the surface area of the sides. In order to find the sides you would do 70cm times 15cm to find one of the area of the sides. This would give you that one of the area is 1050cm^2. Since there are three you need to multiply by 3. This means that all the rectangles on the side would have a surface area of 3150cm^2. Then you need to find the area of the triangles. So the Area= Height times (1/2)base. Area= 13cm* times 7.5cm. Therefore the area of the triangle is equal to 97.5cm^2. Since there are two this means that the surface area of the two triangles would be equal to 195cm^2. Then in order to find the total surface area you would need to add the triangles with the rectangles which is equal to 3150cm^2 plus 195cm^2 which totals to 3345cm^2.

Therefore the total surface area for the triangle box is 3345cm^2

Perimeter is the sum of length of the sides used to made the given figure. The perimeter of the rectangle is 14±0.2 meters.

Perimeter is the sum of length of the sides used to made the given figure.

The absolute area of the floor can be written as,

Area, A = 3.95m × 3.05m = 12.0475 m²

The Error in the area of the floor is,

(ΔA/A) = (Δl/l) + (ΔW/W)

(ΔA/12.0475) = (0.05/3.95) + (0.05/3.05)

ΔA = 0.35 m²

Hence, the area of the rectangular room is 12.0475±0.35 m².

The perimeter can be,

Maximum Perimeter = 2[(3.95+0.05)+(3.05+0.05)] = 14.2

Minimum Perimeter = 2[(3.95-0.05)+(3.05-0.05)] = 13.8

The Perimeter = [(14.2+13.8)/2 ± (14.2-13.8)/2 ] = 14±0.2 meters

Hence, the perimeter of the rectangle is 14±0.2 meters.

Answer:Godo luck!

Step-by-step explanation:

Answer:

\(A = 2x^2-1600x\)

Step-by-step explanation:

Let the dimensions of the pen be x and y.

Area, A = xy

Let y be the side oppossite the river, therefore:

The perimeter of the pen = 2x+y

Since the rancher has 1600 feet of fencing to enclose the pen.

2x+y=1600

We make y the subject of the formula

y=2x-1600

Substitute y=2x-1600 into the area function

A = x(2x-1600)

The area of the pen as a function of x is therefore:

\(A = 2x^2-1600x\)

Answer:

A(x)=x(800-x/2)

Step-by-step explanation:

Let the dimensions of the pen be x and y.

Area, A = xy

Let y be the side oppossite the river, therefore:

The perimeter of the pen = 2x+y

Since the rancher has 1600 feet of fencing to enclose the pen.

2x+y=1600

We make y the subject of the formula

y=1600-2x

Substitute y=1600-2x into the area function

A = x(1600-2x)

Hours worked on Friday:  6 hr and 30 min = 6.5 hr

Money earned on Friday:  $15.5/hr x 6.5 hr = $100.75

Hours worked on Saturday:  6.5 hr - 1.167 hr = 5.33   *10 min = 10/60 = 0.1667 hr

Money earned on Saturday:  $15.50 x 5.33 hr = $82.67

Hours worked on Monday:  4.167 hr

Money earned on Monday:  $15.50/hr x 4.167 hr = $64.58

Answer:

( a )

First 4 terms are 4,7,12,19 and the 10th term is 103.

( b )

First 4 terms are 2,8,18,32 and the 10th term is 200.

Step-by-step explanation:

We are given both general term of sequence:

\( \displaystyle \large{ (a) \: \: \: {n}^{2} + 3} \\ \displaystyle \large{ (b) \: \: \: 2{n}^{2}}\)

Let's get to the first sequence.

( a )

We are given:-

\( \displaystyle \large{ {n}^{2} + 3} \)

To find first 4 terms, substitute n = 1,2,3,4 in.

Therefore:-

\( \displaystyle \large{ {1}^{2} + 3 = 4} \\ \displaystyle \large{ {2}^{2} + 3 = 4 + 3 = 7} \\ \displaystyle \large{ {3}^{2} + 3 = 9 + 3 = 12} \\ \displaystyle \large{ {4}^{2} + 3 = 16 + 3 = 19} \)

Therefore, first 4 terms are 4,7,12,19.

Next, to find the 10th term, just substitute n = 10.

\( \displaystyle \large{ {10}^{2} + 3 = 100 + 3 = 103} \)

And we're done for part a!

( b )

We are given:-

\( \displaystyle \large{ 2{n}^{2}}\)

Do the same, substitute n = 1,2,3,4 in.

\( \displaystyle \large{ 2({1})^{2} = 2} \\ \displaystyle \large{ 2({2})^{2} = 2(4) = 8} \\ \displaystyle \large{ 2({3})^{2} = 2(9) = 18} \\ \displaystyle \large{ 2({4})^{2} = 2(16) = 32}\)

Therefore, first 4 terms are 2,8,18,32.

Next, find the 10th term, substitute n = 10 in.

\( \displaystyle \large{ 2{(10)}^{2} = 2(100) = 200} \)

Thus, the 10th term is 200.
