The area of the city is growing at a rate of 4/3 square miles per year in 1995.

Let's consider the width of the city w(t) and the length l(t)

where t is the time in years.

In 1995, the width is 3 miles and the length is 8 miles,

w(0) = 3

l(0) = 8

We know that the width is growing at a rate of 1 mile in 6 years

w'(t) = 1/6

Similarly, we know that the length is growing at a rate of 1 mile in 3 years,

l'(t) = 1/3

The area of the city A(t) is given by:

A(t) = w(t) × l(t)

Take the derivative of A with respect to time t:

A'(t) = w'(t) × l(t) + w(t) × l'(t)

Substitute the values

A'(0) = w'(0) × l(0) + w(0) × l'(0)

= (1/6) × 8 + 3 × (1/3)

= 4/3

Therefore, the growth rate is  4/3 square miles per year

(a) V = (nRT)/P or V = Knt/T. (b) V is multiplied by 38 if n is doubled, according to ideal gas law, T is reduced by 1/20, and P is reduced by 1/20.

(a) Utilizing the ideal gas regulation, we have PV = nRT, where R is the gas consistent. Reworking the condition, we get V = (nRT)/P. Since V is straightforwardly corresponding to n, T, and K, we can compose V = Knt/T, where K is the steady of proportionality.

(b) Assuming the quantity of moles is multiplied, n becomes 2n. Assuming the temperature and strain are both decreased by a component of 1/20, then, at that point, T becomes 19/20 T and P becomes 1/20 P. Subbing these qualities into the situation V = Knt/T, we get:

V = K(2n)(19/20 T)/(1/20 P)

V = K(38nT/P)

Thus, the volume V is duplicated by a component of 38 when the quantity of moles is multiplied and both the temperature and the strain are diminished by an element of one 20th.

Step-by-step explanation:

Recall the three trig functions remember SOH CAH TOA

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Here we are given an angle as well as the hypotenuse(longest side) and we want to find h which is opposite of the given angle.
When dealing with opposite and hypotenuse we use the trig function sine

Knowing this we create an equation and plug in what we are given

Sin = Opposite / Hypotenuse

Sin(48) = h / 15

==> multiply both sides by 15

The equation in slope intercept form is : \(y = \frac{1}{8} x - 223.05\)

The slope intercept form is a process used to determine the equation of a straight line in the coordinate plane. It can be used to determine the equation of a line when given the slope of the straight line and the y-intercept

The slope-intercept form of a line is:

y = mx+b

where m is the slope of the line and b is an intercept of the y-axis.

\(m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }\)

\(m = \frac{26.7 - 23.2 }{1998- 1970}\)

\(m = \frac{1}{8}\)

So,

\(y = \frac{1}{8} x + b\)

To find b we get the point (1970, 23.2) and introduce it in the previous equation.

\(23.2= \frac{1}{8} (1970)+ b\)

⇒ 23.2 - 246.25 = b

⇒ b = - 223.05

Then, the equation is : \(y = \frac{1}{8} x - 223.05\)

Answer: C. 64 ft

Step-by-step explanation:

A six-sided dice is rolled twice then the probability that the larger of the two rolls was equal to 3, is 0.1389.

A six-sided dice is rolled twice.

Then the possibility of getting numbers in one rolled = 6

The possibility of getting numbers in second rolled = 6

So the possibility of getting numbers in both rolled = 6 × 6

The possibility of getting numbers in both rolled = 36

Let A be the event that have the larger of the two rolls was equal to 3.

So the possible outcomes;

A = {(1,3), (2,3), (3,3), (3,2), (3,1)}

So total number of possible outcomes to getting larger of the two rolls was equal to 3 = 5

Then the probability that the larger of the two rolls was equal to 3 = Number of possible outcome/Total of possible outcome

The probability that the larger of the two rolls was equal to 3 = 5/36

The probability that the larger of the two rolls was equal to 3 = 0.1389

Answer:

An estimate of the number of female members who are over 50 years of age is 28 members

Step-by-step explanation:

The covered area art

0 - 20 = 1.6 * 20 = 32

20 - 30 = 1.9 * 10 = 19

30 - 40 = 1.8*10 = 18

40 - 60 = 1.1 * 20 = 22

> 60 = 0.8*30 = 24

Adding together gives;

32 + 19 + 18 + 22 + 24 = 115

The number of members that are 50 years and over is given as follows;

Half of the members in the 40 to 60 range plus all members that are over 60

Which give;

1/2*22 + 24 = 35

Given that 80% of the members over 50 are female, we have that the number of members that are female and over 50 = 0.8*35 = 28 members.

Answer:

Estimated Value = 28

Step-by-step explanation:

0 - 20 = 1.6 x 20 = 32

20 - 30 = 1.9 x 10 = 19

30 - 40 = 1.8 x 10 = 18

40 - 60 = 1.1 x 20 = 22

60 = 0.8 x 30 = 24

32 + 19 + 18 + 22 + 24 = 115

1/2 x 22 + 24 = 35

50 = 0.8 x 35 = 28

Based on this information, we can conclude that the order of simulations from the least sample size (n) to the greatest sample size (n) is:
C) Simulation B, simulation A, simulation C

Based on the given information, we can determine the order of simulations from the least sample size (n) to the greatest sample size (n) by examining the histograms.

Looking at the histograms, we can see that the relative frequencies for each simulation are centered around the population proportion of 0.70.

However, we need to consider the relative frequencies that are closest to 0.70, as they indicate the simulations with sample sizes closest to the population size.

Comparing the histograms, we can see that the relative frequency closest to 0.70 in Simulation A is 0.69. In Simulation C, the relative frequency closest to 0.70 is also 0.70.

However, in Simulation B, the relative frequency closest to 0.70 is 0.80.

The expression that represents the cost after the 11% discount is 0.89c. This means that Boubacar will pay 89% of the original cost after the discount has been applied.

To calculate the discount, you need to determine the discount rate, which is usually a percentage of the original price. Multiply the discount rate by the original price to find the amount of the discount.

Finally, subtract the discount amount from the original price to get the discounted price.

The discount that Boubacar gets on his purchase is 11% of the total cost before tax and discount. To calculate the discount, we multiply the total cost (c) by 11% or 0.11, which gives us:

Discount = 0.11c

To find the cost after the discount, we subtract the discount from the total cost. This gives us:

Cost after discount = c - Discount

Cost after discount = c - 0.11c

Cost after discount = 0.89c

Step-by-step explanation:

An infinite slope is simply a vertical line. When you plot it on a line graph, an infinite slope is any line which runs parallel to the y-axis. You can also describe this as any line that doesn't move along the x-axis but stays fixed at one constant x-axis coordinate, making the change along the x-axis.

To find the volume of the solid, we need to integrate the area of each cross-section with respect to the \(\( x \)-axis.\) So, evaluating the integral , we get:
\(\( \text{Volume} = \frac{128}{3} \)\) cubic units.

To find the volume of the solid, we need to integrate the area of each cross-section with respect to the \(\( x \)-axis.\)

The base of the solid is a semicircle given by the equation \(\( y = \sqrt{16 - x^2} \), where \( -4 \leq x \leq 4 \).\)

The cross sections perpendicular to the \(\( x \)\)-axis are squares.

Since squares have equal side lengths, we can find the side length of each square by doubling the value of \( y \).

So, the side length of each square is \(\( 2y = 2\sqrt{16 - x^2} \).\)

To find the area of each cross-section, we square the side length:
\(\( (\text{Area}) = (2\sqrt{16 - x^2})^2 = 4(16 - x^2) \).\)

Now, we integrate this area from \(\( x = -4 \) to \( x = 4 \)\) to find the volume:
\(\( \text{Volume} = \int_{-4}^{4} 4(16 - x^2) \, dx \).\)

Evaluating this integral, we get:
\(\( \text{Volume} = \frac{128}{3} \)\) cubic units.

8√3 - 4√3 = 4√3 subtract 4 from 8 the common root stays same

2√3 x √32 ➡ 2√3 x 4√3 too add the expressions we first need to make the roots common then add 4 and 2

Answer:

1. \(5\sqrt{2}\)

2. \(4\sqrt{3}\)

3. \(8\sqrt{6}\)

Step-by-step explanation:

Number 1:

We can treat \(\sqrt{2}\)  as a variable in which we are multiplying 4 by. Let's call \(\sqrt{2}\) x.

This makes our expression \(4x + x\). Combining like terms, we get \(5x\). This means that \(4\sqrt{2} + \sqrt{2} = 5\sqrt{2}\).

Number 2:

Again, we can use the same logic as we did in number 1. Let's treat \(\sqrt{3}\) as a variable y.

\(8y-4y\)

Subtracting a y term from a y term will equal the difference between the coefficients times y. So it's \(4y\). This means that  \(8\sqrt{3}-4\sqrt{3}=4\sqrt{3}\)

Number 3:

When we multiply radicals, we want to put the radicals in \(\sqrt{x}\) form.

\(\sqrt{32}\) is already in this form.

However \(2\sqrt{3}\) is not.

\(2\sqrt{3}\) is the same thing as \(\sqrt{3\cdot2^2} = \sqrt{3\cdot4} = \sqrt{12}\).

Now we multiply these radicals by multiply the term inside the square root sign

\(\sqrt{32}\cdot\sqrt{12}=\sqrt{32\cdot12} =\sqrt{384}\)

384 is divisible by 64, so:

\(\sqrt{384} = \sqrt{64\cdot6} = 8\sqrt{6}\)

Step 1: Calculate the total cost for the first hour. The total cost for the first hour is $2,000.

Step 2: Calculate the cost for each additional hour. The cost for each additional hour is $1,000.

Step 3: Calculate the total cost. To calculate the total cost, add the cost for the first hour ($2,000) to the cost for each additional hour ($1,000) multiplied by the number of additional hours (n). This gives us a total of P = 2,000 + 1,000(n + 1).

Therefore, the correct expression for the total cost is P = 2,000 + 1,000(n + 1).

C(x)=F+V is the generic form of the cost function formula (x) C(x) = F + V(x), where x is the number of units, V(x) is the total variable cost, and C(x) is the overall cost of production.

Step-by-step explanation:

I'll do part (a) to get you started.

One possible answer to part (a) is 25,11,14,2,7,9,16

There are likely other possible answers.

The explanation is below.

==============================================================

Let's say 7 is the anchor value and we want to see which values could be its next door neighbor.

To summarize this subsection, the anchor value 7 could have the neighbors 9 and 2.

So we could have 2,7,9 or 9,7,2 as a subsequence. We'll keep this in mind for later.

------------------------------------------------

Now we'll make 11 the anchor. We already checked 7 and it doesn't work.

9 doesn't work either because 11+9 = 20 isn't a perfect square

Of that list, only 14 and 25 are possible neighbors of the anchor value 11.

So we could have the subsequence 14,11,25 or 25,11,14.

------------------------------------------------

If 9 is the anchor, then,

The values 7 and 16 are possible neighbors of 9. We could have the subsequence 7,9,16 or 16,9,7

Let's go back to the subsequence 2,7,9 and tack 16 at the end to get 2,7,9,16

------------------------------------------------

If 14 is the anchor, then,

We could have the subsequence 11,14,2 or 2,14,11

Let's go with the first option and stick "11,14,2" in front of "2,7,9,16" to end up with the larger subsequence 11,14,2,7,9,16

We can then stick 25 at the front because 25+11 = 36 is a perfect square.

------------------------------------------------

So one possible sequence of values is 25,11,14,2,7,9,16

Here's the verification

Each pair of adjacent terms add up to a perfect square, so the answer is confirmed.

The absolute maximum of f(x) is e^(2pi), which occurs at x = 2pi, and the absolute minimum of f(x) is approximately -1.30, which occurs at x = 5*pi/4

a. To find the absolute maximum and minimum values of f(x), we can use the first derivative test and the endpoints of the given interval.

First, we find the first derivative of f(x):

f'(x) = e^xcos(x) - e^xsin(x)

Then, we find the critical points of f(x) by setting f'(x) = 0:

e^xcos(x) - e^xsin(x) = 0

e^x(cos(x) - sin(x)) = 0

cos(x) = sin(x)

x = pi/4 or x = 5*pi/4

Note that these critical points are in the domain [0, 2*pi].

Next, we find the second derivative of f(x):

f''(x) = -2e^xsin(x)

We can see that f''(x) is negative for x in [0, pi/2) and (3pi/2, 2pi], and f''(x) is positive for x in (pi/2, 3*pi/2).

Therefore, x = pi/4 is a relative maximum of f(x), and x = 5*pi/4 is a relative minimum of f(x). To find the absolute maximum and minimum of f(x), we compare the values of f(x) at the critical points and the endpoints of the domain:

f(0) = e^0cos(0) = 1

f(2pi) = e^(2pi)cos(2pi) = e^(2pi)

f(pi/4) = e^(pi/4)cos(pi/4) ≈ 1.30

f(5pi/4) = e^(5*pi/4)cos(5pi/4) ≈ -1.30

Therefore, the absolute maximum of f(x) is e^(2pi), which occurs at x = 2pi, and the absolute minimum of f(x) is approximately -1.30, which occurs at x = 5*pi/4.

b. To find the intervals on which f(x) is increasing, we look at the sign of f'(x) on the domain [0, 2pi]. We know that f'(x) = 0 at x = pi/4 and x = 5pi/4, so we can use a sign chart for f'(x) to determine the intervals of increase:

x 0 pi/4 5*pi/4 2*pi

f'(x) -e^0 0 0 e^(2*pi)

f(x) increasing relative max relative min decreasing

Therefore, f(x) is increasing on the interval [0, pi/4) and decreasing on the interval (pi/4, 2*pi].

c. To find the x-coordinate of each point of inflection of the graph of f, we need to find where the concavity of f changes. We know that the second derivative of f(x) is f''(x) = -2e^xsin(x), which changes sign at x = pi/2 and x = 3*pi/2.

Therefore, the point (pi/2, f(pi/2)) and the point (3pi/2, f(3pi/2)) are the points of inflection of the graph of f.
