Answer:

A = π(14t)²

Step-by-step explanation:

The radius is increasing at the rate of 14 cm per second.

We need to find the formula for the area A of the circle as the function of time t.

Initial area of the circle,

A = πr², where r is the radius of the circle

Area as a function of t will be :

A = π(14t)²

Here, 14t is the radius of the wave.

We want to get the area function given that we know how the radius increases with time.

The function is:

A(t)  = (615.44 cm^2)*t^2

Here we know that the radius of a circular wave increases by 14cm each second.

Then we can write the radius as a function of time as:

r(t) = 14cm*t

where t is the time, in seconds, since the wave begins.

Now, remember that the area of a circle of radius r is given by:

A = pi*r^2

where pi = 3.14

Replacing r by the radius function, we get:

A(t) = 3.14*(14cm*t)^2 = (615.44 cm^2)*t^2

This is the area function we wanted to get.

Answer:

Linear Function

Step-by-step explanation:

there are an infinite number of ordered pairs of x and y that satisfy the equation.

Answer:

(a) Not independent

(b) The probability the woman has a Bachelor's Degree and has never married is 0.046.

Step-by-step explanation:

Denote the events as follows:

X = American women aged 25 years or older have a Bachelor's Degree

Y = American women aged 25 years or older have never married

The information provided is as follows:

P (X) = 0.202

P (Y) = 0.165

P (X | Y) = 0.228

P (Y | X) = 0.186

(a)

If two events, say A and B are independent then,

P (A|B) = P (A) and P (B|A) = P (B)

Since,

P (X | Y) ≠ P (X)

P (Y | X) ≠ P (Y)

The events "have a Bachelor's Degree" and "never married" are not independent.

(b)

Compute the probability the woman has a Bachelor's Degree and has never married as follows:

[tex]P(X\cap Y)=P(X|Y)\times P(X)\\\\=0.228\times 0.202\\\\=0.046056\\\\\approx 0.046[/tex]

Thus, the probability the woman has a Bachelor's Degree and has never married is 0.046.

Answer: 10 days

Step-by-step explanation: So if the librarian sorted at a constant rate, then they sorted the same amount of books all 6 days. If they still have 200 books left to sort, then they sorted 300 books over 6 days. This means that they sorted 50 books per day. 200 divided by 50 is 4. So it will take 4 more days to finish sorting all the books. So altogether, it will take 10 days to sort all of the books.

The total number of required days is 10.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

The total number of books is 500.

The books left after 6 days is 200.

The number books read per day is given as,

(500 - 200)/6

= 300/6

= 50

Now, number of days the remaining number of books to be read is,

200/50 = 4

Thus, the total number of days is 6 + 4 = 10.

Hence, it will take 10 days from the start to finish all the books.

Answer:

It is known that the variance of a popualtion equals 1,936.

Step-by-step explanation:

That should be correct!!!

There is a 0.95 probability that the sample mean will provide a margin of error of 7.84.

The term probability refers to the likelihood of an event occurring.

Given that;

The variance of a population = 1,936

And, A random sample of 121 has been taken from the population.

Now,

Since, Standard deviation = √ Variance

                                        = √1,936

                                        = 44

Hence, The standard error = 44 / √121

                                         = 44 /11

                                         = 4

We know that;

The critical z factor for a confident interval of 0.95 = ± 1.96

Thus, The sample mean will provide a margin of error = 4 × 1.96

                                                                                    = 7.84

It's B trust

Step-by-step explanation:

The required balance at the beginning of April is $796.87. Option C is correct.

Simple interest is defined as the percentage of earnings on the lending for a period of time

To determine Ruth's balance at the beginning of April, we can work backward from her total at the start of May.

Let's call Ruth's balance at the beginning of May "B".

We know that during the April billing cycle:

She made a $45.17 payment on April 10th

She made a $88.34 purchase on April 17th

The APR is 10.91%

So, B = B - $45.17 - $88.34 + (B * 0.1091 * 30 / 365)

Solving for B, we get:

B = $796.87

So, the answer is C. $796.87.

Answer:

n = 2

Step-by-step explanation:

Since ∆A is similar to ∆B, therefore, the ratio of their corresponding sides would be equal.

Thus:

[tex] \frac{10}{n + 2} = \frac{6}{3} [/tex]

[tex] \frac{10}{n + 2} = 2 [/tex]

Multiply both sides by (n + 2)

[tex] \frac{10}{n + 2}(n + 2) = 2(n + 2) [/tex]

[tex] 10 = 2n + 4 [/tex]

Subtract 4 from each side

[tex] 10 - 4 = 2n + 4 - 4 [/tex]

[tex] 6 = 2n [/tex]

Divide both sides by 2

[tex] \frac{6}{2} = \frac{2n}{2} [/tex]
