❤️Hello!❤️ The answer is 11.31 feet                                                                    arc length = radius * central angle (in radians)

arc length = 12.6 * 2*PI/7

arc length = 25.2 * PI/7  

arc length = 11.31 feet ☯️Hope this helps!☯️  ↪️ Autumn ↩️

Answer 2

Answer:

11.31 ft is the arc length.

Step-by-step explanation:

We have given the radius r = 12.6 ft and arc intercept by central angle

Ф = 2π/7.

We have to find the arc length.

We know the formula to find the arc length that is:

L = rФ

Putting the values we get,

 L= 12.6 × 2π/7

L = 25.2 π/7

L = 11.31 ft  is the answer.

11.31 ft is the arc length.

Part 2) The base is [tex]7.5\ in[/tex]  and the height is [tex]18.75\ in[/tex]

Step-by-step explanation:

case 1) Right isosceles triangle of the left

Let

x------> the base of the rectangle

y----> the height of the rectangle

Remember that

In a right isosceles triangle the lengths of the legs of the triangle is the same

[tex]y+x+y=45[/tex]

[tex]y=2.5(7.5)=18.75\ in[/tex]

Final answer:

In Case 1, the sides of the rectangle are 5x, 45, 45, and 2x. In Case 2, the sides of the rectangle are 5x, 45/sqrt(2), 45/sqrt(2), and 2x.

Explanation:

Let's denote the length of one side of the rectangle as 5x and the length of the other side as 2x. Since the triangle is right isosceles, the two legs are of equal length. Let's denote the length of each leg as a. Using the Pythagorean theorem, we can write an equation: a^2 + a^2 = 45^2. Solving for a, we find that a = 45/sqrt(2).

Case 1: Since two vertices of the rectangle lie on the hypotenuse, the length of the rectangle's side that is parallel to the hypotenuse will be equal to the length of that hypotenuse, which is 45. Therefore, the sides of the rectangle will be 5x, 45, 45, and 2x.

Case 2: Since the two vertices of the rectangle lie on the legs of the triangle, the length of the rectangle's side that is parallel to the hypotenuse will be equal to the lengths of the legs, which is 45/sqrt(2). Therefore, the sides of the rectangle will be 5x, 45/sqrt(2), 45/sqrt(2), and 2x.

Find the missing terms of the geometric sequence 81,____, _____ 3

Answers

Subtract the two given numbers:

81 - 3 = 78

Divide by the number of missing numbers +1, so divide by 3:

78/3 = 26

This gives you the difference of each number in the sequence, so now subtract 26 from each one:

81 -26 = 55

55 - 26 = 29

29-26 = 3

The two missing numbers are 55 and 29.

Final answer:

To find the missing terms of a geometric sequence, divide each term by a common ratio.

Explanation:

The given sequence is 81, ____, _____, 3.

To find the missing terms, we need to determine the common ratio of the geometric sequence.

Using the given sequence, we can see that each term is obtained by dividing the previous term by a constant factor. Therefore, the common ratio is 81 divided by the first missing term, which is then divided by the second missing term divided by the third missing term, which is then divided by 3.

To find the first missing term, we can divide 81 by the common ratio. Similarly, to find the second missing term, we can divide the first missing term by the common ratio. The missing terms of the geometric sequence are 27 and 9. Therefore, the complete sequence is 81, 27, 9, 3.

At least how many times must you flip a fair coin before there is at least a 50% probability that you will get at least three heads?

Answers

Final answer:

To get at least a 50% probability of getting at least three heads, you must flip a fair coin at least four times.

Explanation:

To calculate the minimum number of times a fair coin must be flipped before there is at least a 50% probability of getting at least three heads, we can use the concept of probability. Let's assume that flipping a coin is a binary event with two possible outcomes: heads (H) or tails (T).



The probability of getting three or more heads in one flip is zero, since we can only get a maximum of two heads in one flip. However, we can calculate the probability of getting three or more heads in a series of flips.



The probability of getting at least three heads in one flip is zero, but we can calculate the probability of getting at least three heads in two flips, three flips, four flips, and so on. We continue calculating the probability until we find the number of flips that gives us a probability of at least 50%.



Using this method, we find that we need to flip the coin at least 4 times to have a probability of at least 50% of getting at least three heads. This means that after flipping the coin four times (or more), there is a better than 50% chance of getting at least three heads.

The slope of a roof is called the pitch and is defined as follows:
pitch = rise of roof
½ span of roof
Find the pitch of a roof if the rise is 12 feet and the span is 30 feet.
Find the pitch of a roof if the rise is 4 feet and the span is 24 feet.

Answers

Answer:

a) 4/5

b) 1/3

Step-by-step explanation:

Put the numbers in the formula and evaluate.

a) pitch = (rise)/(1/2·span)

= (12 ft)/(1/2·30 ft) = 12/15 = 4/5

___

b) pitch = (4 ft)/(1/2·24 ft) = 4/12 = 1/3

Final answer:

The pitch of a roof is calculated by dividing the rise of the roof by half the span of the roof. The pitch of a roof with a 12 feet rise and 30 feet span is 0.8. The pitch of a roof with a 4 feet rise and 24 feet span is 0.333.

Explanation:

The pitch of a roof can be calculated using the equation: pitch = rise of roof / (½ span of roof).

For the first part of your question, where the rise is 12 feet and the span is 30 feet, you substitute these values into the above equation: pitch = 12 / (½ * 30) = 0.8

For the second part, where the rise is 4 feet and the span is 24 feet, when these values substituted into the equation you get: pitch = 4 / (½ * 24) = 0.333

So, the pitch of the first roof is 0.8 and the pitch of the second roof is 0.333

B) 21.02 < 20.55
C) 21.05 < 20.30
D) 21.22 > 21.30


Answers

Answer:

A) 20.82 > 20.55

Step-by-step explanation:

Hopefully, your issue is with the symbols (< vs >) rather than actually determining which number is larger or smaller.

The wide-open end of the symbol (the left side, in the case of >) indicates the larger (more positive) number.

So, the meanings of the symbols are ...

> — "is greater than"

< — "is less than"

The only true statement of those listed is ...

20.82 is greater than 20.55, or 20.82 > 20.55 . . . . selection A

_____

When writing number comparisons, I like to use the < symbol, because it puts the numbers in number-line order. That is, the smaller (or more negative) number is on the left, just as it is on a number line.

You trade the places of the numbers when changing the symbol. For example, answer choice A could be rewritten as ...

20.55 < 20.82

You know that 20.55 is to the left of 20.82 on the number line, so you know this statement is true.

Which of the following describes the given graph of the function over the interval [2, 6]? A. increasing B. constant C. decreasing D. decreasing to increasing

Answers

A.Increasing is the answer

Final answer:

To determine the function's behavior over an interval, compare the y-values as the x-values increase. It could be increasing, decreasing, constant, or changing direction. Choose the description that matches the graph's movement over the given interval.

Explanation:

To determine how the function behaves over the interval [2, 6], we must look at the description of the graph presented. If during the interval the function is always moving upwards as the x-values increase, then it is increasing. If it moves downwards, it is decreasing. If the graph stays at the same level without moving up or down, then it would be constant. If the graph changes its direction, from either increasing to decreasing or vice versa, then it would be described as decreasing to increasing or increasing to decreasing, accordingly. Given these possibilities, the student should match the behavior of the graph with one of these descriptions.

A baker used 12 cups of batter to make muffins. It took 2/3 cup of batter to make 1 muffin. How many muffins did the baker make? (A) 6 muffins (B) 8 muffins (C) 18 muffins (D) 36 muffins

Answers

Dividing the total batter of 12 cups by the amount needed per muffin, which is 2/3 cup, reveals that the baker made 18 muffins. The answer is option C.

To find out how many muffins the baker made, we need to use the information given about the amount of batter used and how much batter is required for one muffin. According to the problem, the baker used 12 cups of batter in total and each muffin requires 2/3 cup of batter.

We start by setting up a simple division to find the answer:

(Total amount of batter) \/ (Amount of batter per muffin) = Number of muffins

12 cups \/ 2/3 cups per muffin = 18 muffins

This calculation reveals that the baker made 18 muffins. Therefore, the correct answer is (C) 18 muffins.

7. As with adding any fractions, first you find a common denominator. When the fractions are rational expressions, it often helps to factor the denominators.

6/(x^2 -16) -2/(x^2 -x -12) = 6/((x -4)(x +4)) -2/((x -4)(x +3))

= (6(x +3) -2(x +4))/((x -4)(x +3)(x +4)) . . . . . using a common denominator

= (6x +18 -2x -8)/((x -4)(x +3)(x +4))

= (4x +10)/((x^2 -16)(x +3))

= (4x +10)/(x^3 +3x^2 -16x -48)

_____

9. First you simplify the denominator:

2/25 -5/16 = (2·16 -5·25)/(25·16) = -93/400

Then you perform the division. This can be done by multiplying by the inverse of the denominator.

(4/5)/(2/5 -5/16) = (4/5)·(-400/93) = -320/93

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 75 pounds. The truck is transporting 70
large boxes and 65 small boxes. If the truck is carrying a total of 5075
pounds in boxes, how much does each type of box weigh?

Answers

Answer:

large box weights 40 pounds & small box weights 35 pounds

Step-by-step explanation:

We can write 2 equations and solve simultaneous.

Let x be weight of large box and y be weight of small box

"The combined weight of a large box and a small box is 75 pounds.":

[tex]x+y=75[/tex]

"The truck is transporting 70  large boxes and 65 small boxes. If the truck is carrying a total of 5075  pounds":

[tex]70x+65y=5075[/tex]

Now we can solve for x in the first equation, which is x = 75 -y

We now substitute this into the 2nd equation and solve for y:

[tex]70x+65y=5075\\70(75-y)+65y=5075\\5250-70y+65y=5075\\-5y=5075-5250\\-5y=-175\\y=35[/tex]

Using y = 35 and plugging that into the 1st equation, we can solve for x:

[tex]x+y=75\\x+35= 75\\x= 75 - 35\\x=40[/tex]

Hence, large box weights 40 pounds & small box weights 35 pounds

Two cyclists, Alan and Brian, are racing around oval track of length 450m on the same direction simultaneously from the same point. Alan races around the track in 45 seconds before Brian does and overtakes him every 9 minutes. What are their rates, in meters per minute?

Answers

Answer:

Alan: 200 m/min

Brian: 150 m/min

Step-by-step explanation:

Let "a" and "b" represent Alan and Brian's rates in meters per minute, respectively. The rate at which Alan is lapping Brian is the difference in their rates:

a - b = (450 m)/(9 min) = 50 m/min

This lets us write Brian's rate in terms of Alan's as ...

a -50 = b

The time to complete one oval differs by 3/4 minute (45 seconds), so we have ...

time = distance/speed

450/b - 450/a = 3/4

Multiplying by 4ab/3 gives ...

600(a -b) = ab

Substituting from above, we can rewrite this as ...

600·50 = a(a -50)

a^2 -50a -30000 = 0 . . . . . quadratic rearranged to standard form

(a -200)(a +150) = 0 . . . . . . .factored

a = 200 or -150 . . . . only the positive solution is useful here

Alan's rate is 200 m/min; Brian's rate is 150 m/min.

_____

Check

It takes Alan 450/200 min = 2.25 min to complete one oval. It takes Brian 450/150 = 3 min to complete one oval. That is 3-2.25 = 0.75 min = 45 seconds longer than Alan.

After 9 minutes, Alan will have gone (200 m/min)·(9 min) = 1800 m = 4 laps, while Brian will have gone (150 m/min)·(9 min) = 1350 m = 3 laps. Hence Alan will overtake Brian at the 9-minute mark.

Which function has an inverse that is not a function?

f(x) = x^2

f(x) = 2x

f(x) = x + 2

f(x) = √x

Answers

Answer:

your choice is correct

Step-by-step explanation:

f(x) = x^2 does not pass the horizontal line test (a horizontal line intersects its graph in two places), so its inverse does not pass the vertical line test. The inverse is not a function.

_____

Comment on the graph

The original function f(x)=x^2 is shown by the red curve. Its reflection across the orange dashed line y=x gives the inverse relation, in blue. The black horizontal and vertical lines show the multiple points of intersection with the curves, indicating the inverse relation is not a function.

Answer:

A) f(x)=x^2

As the angle θ increases to 90° the value of tan(θ)

A. decreases rapidly.
B. approaches +1.
C. increases rapidly.
D. approaches –1.

Answers

Answer:

C. increases rapidly.

Step-by-step explanation:

tan(θ) =  sin(θ)/cos(θ)

Now, when sin 90 = 1

and cos 90 = 0

so, tan(90) = 1/0 = not defined.

(1/0 is infinity and its value is not defined)

So, when angle θ increases to 90°, then the value of tan(θ) increases rapidly, as shown in the figure below.

What is the radius of a circle whose equation is x2 + y2 + 8x – 6y + 21 = 0? units

Answers

Answer:

2

Step-by-step explanation:

x²+8x+y²-6y= -21;

it means r²=2²; ⇒ r=2.

Explain why a rotation of 270∘ clockwise will result in the same transformation as a rotation of 90∘ counterclockwise

Answers

Because there is a maximum rotation of 360°, so if you rotate x° clockwise it's the same as if you rotate (360-x)° counterclockwise.
