Answer:

56.5 inches

Step-by-step explanation:

We are given the area of a circle and we are to find the circumference of the same circle.

We know that the area of a circle is given by [tex]\pi r^2[/tex] so equating the given value to get.

[tex]\pi r^2=254.47[/tex]

[tex]r^2=\frac{254.47}{\pi }[/tex]

[tex]r=\sqrt{81.00}[/tex]

r = 9 inches

Since we now know the radius of the circle so we can find its circumference.

Circumference of circle = [tex]2\pi r[/tex] = [tex]2\pi (9)[/tex] = 56.5 inches

Answer: 56.54 in

Step-by-step explanation:

The area can be calculated with this formula:

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

Where r is the radius

And the circumference can be calculated with this formula:

[tex]C=2\pi r[/tex]

 Where r is the radius

Solve for the radius from  [tex]A=\pi r^2[/tex]. Then, tha radius is:

[tex]r=\sqrt{\frac{A}{\pi }}=\sqrt{\frac{254.47in^2}{\pi }} =9in[/tex]

Then, the circumference is:

 [tex]C=2\pi (9in)=56.54in[/tex]

No he should have multiplied 5,700 by 0.05

Answer:

The correct option is B) No, he should have multiplied $5,790 by 0.05.

Step-by-step explanation:

Consider the provided information.

He is paid $14.00 per hour, plus 5% commission. He worked 8 hours and sold 6 computers today for a total of $5,790.

Now find his total earning as shown:

$14 × 8 = $112

It is given that he sold 6 computers for a total of $5,790 and he gets a commission of 5% of total sale.

5% = [tex]\frac{5}{100}=0.05[/tex]

Now multiply 0.05 with $5,790

$5,790 × 0.05 = $289.5

Hence, the total income is $112+$289.5=$401.5

To calculate his pay, Henry multiplies 14 × 8, then adds the product to 5,790, then multiplies the sum by 0.05.

Henry's calculation is incorrect as he needs to multiply 5,790 with 0.05 and then he need to add the product of 14 × 8

Therefore, the correct option is B) No, he should have multiplied $5,790 by 0.05.

Step-by-step explanation:

In order to get the mean cost that she wants from the gift, we would need to get the numbers that we already had, and have another set of row with the amount of gifts she needs with the mean she wants.

Here is how it should look like:

$25  $14  $33  $19    x

$25  $25  $25  $25 $25

We are trying to find the number for "x"

Therefore, we would need to use the process of adding, then subtracting after.

Lets add:

[tex]25+14+33+19=91\\\\25+25+25+25+25=125[/tex]

What we would do now is subtract the numbers in order to get the price that Tonya wants from her gift, if she buys another gift.

[tex]125-91=34[/tex]

Tonya should spend $34 on her last gift.

$34 should be your FINAL answer

Step-by-step explanation:

Note that the reciprocal of tan B is by definition the cotangent (cot) of B:

   1                        adjacent side           BC

---------- = cot B = ----------------------- =  ---------

 tan B                   opposite side            AC

Answer:

Hence, The reciprocal of tan B is tan A

B is correct.

Step-by-step explanation:

We are given a right angle triangle. Right angle at ∠C

We need to find the reciprocal of tan B

First we write the formula of tan B using trigonometry identity.

[tex]\tan\theta=\dfrac{\text{Opposite}}{\text{Base}}[/tex]

In ΔABC, ∠C=90°

[tex]\tan B=\dfrac{AC}{BC}[/tex]

Now we reciprocal it.

[tex]\dfrac{1}{\tan B}=\dfrac{BC}{AC}[/tex]

[tex]\tan A=\dfrac{BC}{AC}[/tex]

Comparing both equation ( Right sides equal )

[tex]\dfrac{1}{\tan B}=\dfrac{BC}{AC}=\tan A[/tex]

[tex]\dfrac{1}{\tan B}=\tan A[/tex]

Hence, The reciprocal of tan B is tan A.

Answer:

Step-by-step explanation:

12 seconds for 28 claps

1 second for (28/12) claps

? claps for 1.75 mins?

1.75 minutes = 105 seconds (1.75×60 = 105)

105 seconds for (28/12)×105 claps

= 245 claps

Answer:

Your friends can clap their hands 245 times in 1.75 minutes.

Step-by-step explanation:

First of all, you should know how many seconds represents 1.75 minutes, because the amount of applause your friends can make is in that measure of time.  In order to make this conversion, a simple rule of three is made, knowing that 1 minutes is 60 seconds:

If 1 minute is 60 seconds, how many seconds are 1.75 minutes?

[tex]\frac{1.75minutes*60seconds}{1minute} =105 seconds[/tex]

Knowing that your friend can clap his hands 28 times in 12 seconds and knowing that 1.75 minutes is 105 seconds, you can perform a rule of three again:

If they can clap their hands 28 times in 12 seconds, how many applause can they make in 105 seconds?

[tex]\frac{105seconds*28applause}{12} =245 applause[/tex]

Then your friends can clap their hands 245 times in 105 seconds, which is 1.75 minutes.

(X-2)^2 +(y-5)^2 = 256

Answer:

1) g(x) ----> y-intercept -3

2) h(x) ----> y-intercept -1

3) f(x) ----> y-intercept 2

Step-by-step explanation:

we know that

The y-intercept or initial value, is the value of y when the value of x is equal to zero

Calculate the y-intercept of each exponential function

case 1) A function g, has a growth factor of 2 and a value of 1, and passes through the point (1,-2)

The exponential function is equal to

[tex]g(x)=1(2)^{x}+c[/tex]

Find the value of c

For x=1, g(x)=-2

substitute

[tex]-2=(2)^{1}+c[/tex]

[tex]-2=2+c[/tex]

[tex]c=-4[/tex]

so

[tex]g(x)=(2)^{x}-4[/tex]

Find the y-intercept

For x=0

[tex]g(0)=(2)^{0}-4[/tex]

[tex]g(0)=-3[/tex]

case 2) Observing the table

For x=0

f(0)=2

therefore

The y-intercept of f(x) is 2

case 3) Observing the graph

For x=0

h(0)=-1

therefore

The y-intercept of h(x) is -1

Order the functions from least to greatest y-intercept

1) g(x) ----> y-intercept -3

2) h(x) ----> y-intercept -1

3) f(x) ----> y-intercept 2

Final answer:

To find the y-intercept of an exponential function, evaluate it at x = 0. The constant term in the function represents the y-intercept. Order the functions by comparing these constant terms from least to greatest.

Explanation:

To find the y-intercept of an exponential function, we need to evaluate the function when x is equal to zero. The exponential function is usually given in the form f(x) =[tex]ab^x[/tex], where a is the y-intercept. This is because any number (except zero) raised to the power of zero is 1, so[tex]b^0[/tex] will always be 1, leaving us with f(0) = a.

After finding the y-intercept for each function, order them from least to greatest to complete the task. For example, if we have functions such as f(x) = [tex]2(3)^x, g(x) = 5(2)^x[/tex], and h(x) = [tex]-1(4)^x,[/tex] their y-intercepts would be 2, 5, and -1 respectively. Ordered from least to greatest, the functions by their y-intercepts would be h(x), f(x), g(x).

Answer:

63,960 possibilities in total.

Step-by-step explanation:

For the first number, you can choose from 41 different numbers, so there are 41 possibilities.

For the second number, you cannot choose the same as the first one, so you are now limited to 40 possibilities.

For the third number, you are down to 39 possibilities since you cannot pick the same as the first two ones.

So, you have 41 * 40 * 39 = 63,960 possibilities in total.

Picking a new combination is easy... remembering it is the hard part :-)

If you want to calculate it from a formula standpoint, the base formula would be:

[tex]P(n,r) = \frac{n!}{(n-r)!} = \frac{41!}{(41-3)!} = 63960[/tex]

Where n is the total numbers possible and r is the quantity of numbers you have to pick.

Answer:

-3/5

Step-by-step explanation:

you can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of a line when given two points.

we are given both the x and y intercepts, and we can use those in the formula.

the x intercept is (5,0) and the y intercept is (0,3)

i will treat (5,0) as my x1 and y1, and (0,3) as my x2 and y2

[tex]\frac{3-0}{0-5}[/tex] = -3/5

the slope is -3/5

The slope of the line is -3/5 if the line p has an x-intercept of 5 and a y-intercept of 3.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a line p:

The x-intercept of line p is 5 or (5, 0)

The y-intercept of line p is 3 or (0, 3)

The slope m can be evaluated:

[tex]\rm m =\dfrac{3-0}{0-5}[/tex]

m = -3/5

Thus, the slope of the line is -3/5 if the line p has an x-intercept of 5 and a y-intercept of 3.

Answer:

Those are trigonometric identities. and tan is just a shortened version of tangent, same for cos is means cosine

   The sine/sin of the angle = the length of the opposite side divided by the length of the hypotenuse.

   The cosine/cos of the angle = the length of the adjacent side divided by the length of the hypotenuse.

   The tangent/tan of the angle = the length of the opposite side divided by the length of the adjacent side.

The area of a circle is given by the formula A = π r²

We already have r (3cm)... so we can plug it directly into the equation:

A = π r² = π 3² = 9π = 28.26 cm²

Answer:

A = 28.27

Step-by-step explanation:

A = π r^2

A = π 3^2

A= π (9)

A = 28.27433

The expression sin x / csc x + cos x / sec x simplifies to sin^2 x + cos^2 x by using the reciprocal identities of the trigonometric functions csc x and sec x.

The expression sin x / csc x + cos x / sec x can be simplified by substituting the reciprocal identities for the trigonometric functions csc x and sec x. The reciprocal of csc x is sin x and the reciprocal of sec x is cos x. Thus, sin x / csc x becomes sin x / (1/sin x) which simplifies to sin^2 x. Similarly, cos x / sec x becomes cos x / (1/cos x) or cos^2 x. Therefore, the simplified form of the expression is sin^2 x + cos^2 x.

Answer:

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

138 - n = (n + 1) + (n + 2)

138 - n = n + 1 + n + 2                 combile like terms

138 - n = 2n + 3           subtract 138 from both sides

-n = 2n - 135               subtract 2n from both sides

-3n = -135            divide both sides by (-3)

n = 45

n + 1 = 46

n + 2 = 47

The three consecutive integers in question are 45, 46, and 47. This was solved by setting up and solving a simple algebraic equation.

Let the three consecutive integers be x, x+1, and x+2. According to the problem, the sum of the second and third integers is equal to 138 minus the first one. This can be written mathematically as:

x + (x + 1) + (x + 2) = 138

Solving this equation gives:

3x + 3 = 138
3x = 135
x = 45

Hence, the three consecutive integers are 45, 46, 47.
