Since r = s/2, it follows that , or , or

The arc length as a function of the area of the sector is l=2√A.

What is the area of a sector?

Area of a sector = 1/2 * arc length(l) * radius(r)

[tex]A=[/tex] [tex]\frac{1}{2} l*r[/tex]......(1)

It is given that the arc length of a sector is equal to twice the radius.

This means [tex]l=2r\\[/tex]

So, [tex]r=\frac{l}{2}[/tex]

Putting the value of r in (1)

A town has a population of 13000 and grows at 4.5% every year. What will be the population after 13 years, to the nearest whole number?

Answers

23,039.
y=13,000(1.045)^t
t=13
You get 1.045 because you add 1+ the percentage in decimal form.

Answer:

population after 13 years is around 23,039

Step-by-step explanation:

A town has a population of 13000 and grows at 4.5% every year.

Population growth is given by [tex]y=a(1+r)^t[/tex]

y is the population after t years

'a' is the initial population= 13000

'r' is the rate of growth=4.5%= 0.045

t is the number of years=13

[tex]y=a(1+r)^t[/tex]

[tex]y=13000(1+0.045)^13[/tex]

K(x)=10x+5 inverse function

Answers

The inverse of the function is k(x) = [tex] \frac{x - 5}{10} [/tex]

You can find the inverse of any function by switching the k(x) value and the x value. After that, solve for the new k(x). The result will be your inverse function. The step-by-step process is below.

k(x) = 10x + 5 ----> Switch the x and k(x)

x = 10k(x) + 5 ----> Subtract 5 from both sides

x - 5 = 10k(x) ----> Divide both sides by 10.

[tex] \frac{x - 5}{10} [/tex] = k(x) ----> Now switch the order for formatting

k(x) = [tex] \frac{x - 5}{10} [/tex]

And this is your new inverse function.

Enter your answers in the boxes to complete the two-way table based on the given data.

Answers

The two-way table is attached.

We start out placing 31 in the Total column beside the Don't Play Baseball row. We then place 16 in the Total row under the Play Football column. 20 goes in the Don't Play Baseball row under the Don't Play Football column.

Since there are 31 people that do not play baseball, and 20 of them don't play football, this leaves us with 31-20=11 that do not play baseball and play football.

There are 58 people total, so this goes in the Total row under the Total column.

There are 58 people, and 31 of them do not play baseball; this leaves us 58-31=27 total that play baseball.

16 total people play football, and 11 of them don't play baseball. This leaves us 16-11=5 people that play football and play baseball.

There are 58 people, and 16 of them play football; this leaves us 58-16=42 total that don't play football.

42 people don't play football, and 20 of them don't play baseball; this leaves us 42-20=22 people that don't play football and play baseball.

5 people play baseball and play football, and 22 people play baseball and don't play football; this gives us 5+22=27 people total that play baseball.

Simplify the function f(x)= 1/2 (27) 2x/3. Then determine the key aspects of the function

Answers

The given expression is:

[tex]f(x)= \frac{1}{2}(27)^{ \frac{2x}{3} } \\ \\ f(x)= \frac{1}{2}((27)^{ \frac{2}{3} })^{x} \\ \\ f(x)= \frac{1}{2}(9)^{x} [/tex]

From the above equation, we can answer all the 4 questions.

a) Initial value occurs when x = 0

So,

[tex]f(0)= \frac{1}{2}(9)^{0}= \frac{1}{2} [/tex]

So, the Initial value of the function is 1/2.

b) Simplified Base:
The base of an exponential function is the term which contains the exponent.
From the simplified equation, we can see that the base has been simplified and is equal to 9.

So, the simplified base is 9

c) Domain:
From the equation we can see that there is no such value which makes the function undefined. So all reall numbers are included in the Domain.

So, Domain is Set of All real numbers.
In Interval notation this can be expressed as: (-∞,∞)

d) Range:
Range is the set of all y values that a function can take. Since the graph is not shifted vertically up or down, the range will be the set of all real numbers greater than zero.

So, Range is equal to All real numbers greater than 0.
In Interval notation, this can be expressed as (0,∞)

Answers

Answer:

Step-by-step explanation:

just got it correct

Final answer:

The function f(x)=(x-9)/(x^3-81x) has three vertical asymptotes at x = 0, x = 9, and x = -9.

Explanation:

To find the vertical asymptote(s) of the function f(x) = (x-9)/(x^3-81x), we need to determine the values of x for which the denominator equals zero. Setting the denominator equal to zero and solving for x, we get:

x^3 - 81x = 0x(x^2 - 81) = 0x(x - 9)(x + 9) = 0

Therefore, the function has three vertical asymptotes at x = 0, x = 9, and x = -9.

Frazier has $1,200 in savings. He works because he is saving money for college, and he earns $9 an hour. If Frazier saves 25 percent of his net pay, after 20 percent is taken out for tax, identify the expression which represents Frazier's savings.

A) 1.8x + 1,200
B) 3.6x + 1,200
C) 7.2x + 1,200
D) 9x + 1,200

Answers

the correct answer is A..!! I think...:(

Answer: The correct option is (A) [tex]1.8x+1200.[/tex]

Step-by-step explanation: Given that Frazier is saving money for college and has $1200 in savings. He earns $9 per hour. He saves 25% of his net pay after 20% taken out for tax.

We are to identify the expression that represents Frazier's savings.

Let, x represents the number of hours for which Frazier works.

So, the net pay of Frazier = $ 9x.

Since 20% of the net pay is taken out for tax, so total pay of Frazier after taking out tax is given by

[tex]I_t=9x-20\%\times 9x=9x-\dfrac{20}{100}\times 9x=9x-\dfrac{9x}{5}=\dfrac{36x}{5}.[/tex]

Now, Frazier's savings from his net pay is given by

[tex]I_s=25\%\times \dfrac{36x}{5}=\dfrac{25}{100}\times \dfrac{36x}{5}=\dfrac{9x}{5}=1.8x.[/tex]

Since Frazier has $1200 already in savings, so the equation representing Frazier's savings will be

[tex]1.8x+1200.[/tex]

Thus, the required equation is [tex]1.8x+1200.[/tex]

Question 1:

We have been given that a bag contains 7 red marbles, 6 green marbles, 5 yellow marbles, and 2 orange. Further we are given that marbles are drawn twice with a replacement. We need to figure out the probability P(Yellow and Green).

Basically, we need to determine the probability that first marble drawn is yellow and second marble drawn is green.

Probability of first marble drawn being yellow is [tex]\frac{5}{20}=\frac{1}{4}[/tex] and probability of second marble drawn being green is [tex]\frac{6}{20}=\frac{3}{10}[/tex].

Therefore, the probability P(Yellow and Green) = [tex]\frac{1}{4}\cdot \frac{3}{10}=\frac{3}{40}[/tex].

Question 2:

We have been given that a coin is tossed and a number cube is rolled and we need to find the probability P(H, prime number).

Probability of getting head on the coin is [tex]\frac{1}{2}[/tex].

Probability of getting a prime number on the cube is [tex]\frac{3}{6}=\frac{1}{2}[/tex].

Therefore, probability P(H, prime number) = [tex]\frac{1}{2} \cdot \frac{1}{2}=\frac{1}{4}[/tex]

A. 50
B. 20
C. 30
D. 40

Answers

To solve this, you need to create two separate equations and set them equal to each other.

Plan A: y = 2x + 50
Plan B: y = 4x + 10

2x + 50 = 4x + 10

Now solve the combined equation.

2x + 50 = 4x + 10
- 10 - 10
2x + 40 = 4x
-2x -2x
40 = 2x
x = 20

you can either graph the following equations,
Plan A: y=2x+50
Plan B: y=4x+10
and see where they intersect, and that will give you the answer.
OR
You can substitute each answer for x, like this,
A. 50
Plan A:
y=2(50)+50
y=100+50
y=150
Plan B:
y=4x+10
y=4(50)+10
y=200+10
y=210
So, therefore, A.50 is not the answer.
B.20
Plan A:
y=2x+50
y=2(20)+50
y=40+50
y=90
Plan B:
y=4x+10
y=4(20)+10
y=80+10
y=90
So, B.20 is correct but always check the rest of the answers. Just in case
C.30
Plan A:
y=2x+50
y=2(30)+50
y=60+50
y=110
Plan B:
y=4x+10
y=4(30)+10
y=120+10
y=130
So, C.30 is incorrect.
D.40
Plan A:
y=2x+50
y=2(40)+50
y=80+50
y=130
Plan B:
y=4x+10
y=4(40)+10
y=160+10
y=170
So, in conclusion the correct answer is B.20.
