the exponential function is n(t) =n° (1+r)∧t, where t is the power refers the time in months after opening and n denotes average customer.

when the rate of increases is occurred very rapidly. In this question, the trendy restaurant has earned reputation.

Given, average number of customers after 11 months of opening = n(11) =310

average number of customers after 15 months of opening= n(15) =456

during this 4 month increases of customer =456 -310 =146

increasing rate of customer per month = 146/4 = 36.5

now increasing rate in percentages = 36.5 %

exponential growth rate, r= 0.365

let, n° is the initial number of customer while opening at t=0 month

now, the exponential function n(t) that model's average number of customers, n after t months of being open will be

  n(t) = n° ( 1+r)∧t

we are given that after 11 months of opening average customer n(11) = 310

now, 310 = n° (1+ 0.365)∧11

n°  = 10

hence, the exponential function = n(t) = 10(1+r)∧t

Explanation:

Coordinates are represented in the form of (x, y)

To know the x coordinates see the value on the x-axis.

To know the y coordinates see the value on the y-axis.

From there we can identify:

A = (x, y) = (-4, 4)

B = (x, y) = (2, 2)

C = (x, y) = (0, -5)

D = (x, y) = (-3, -2) ← Required answer.

The following can be answered by the concept of linearly independent.

1. This equation holds for all values of x only if c1 = c2 = 0. Therefore, y1= cos(x+pi) and y2= sin x are linearly independent.

2. This equation holds for all values of x only if c1+c2 = 0 and c2 = 0. Therefore, the only solution is c1=c2=0, and y1= x and y2= x+1 are linearly independent.

1- To determine if y1= cos(x+pi) and y2= sin x are linearly independent or linearly dependent, we need to check if there exist constants c1 and c2 (not both zero) such that c1y1 + c2y2 = 0 for all values of x.

c1(cos(x+pi)) + c2(sin x) = 0

Using the trigonometric identity cos(x+pi) = -cos x and rearranging, we get:

-c1(cos x) + c2(sin x) = 0

Dividing by sin x, we get:

-c1(cot x) + c2 = 0

This equation holds for all values of x only if c1 = c2 = 0. Therefore, y1= cos(x+pi) and y2= sin x are linearly independent.

2- To determine if y1= x and y2= x+1 are linearly independent or linearly dependent, we need to check if there exist constants c1 and c2 (not both zero) such that c1y1 + c2y2 = 0 for all values of x.

c1(x) + c2(x+1) = 0

Expanding and simplifying, we get:

(c1+c2)x + c2 = 0

This equation holds for all values of x only if c1+c2 = 0 and c2 = 0. Therefore, the only solution is c1=c2=0, and y1= x and y2= x+1 are linearly independent.

Answer:

A line traveling to the left with an open dot on x=1.

Explanation:

The inequality x < 1 basically means "less than 1." On number lines, the further left you go, the smaller the number becomes, and the further right you go, the larger the number becomes. So we know that because it's less or smaller than 1, then the line will be to the left. On the other hand, the inequality does not have a line under it to indicate a "less than or equal to 1," just "less than." Therefore, the dot is open. If there were a line under the inequality, then it would indicate "less than or equal to 1" and the dot would be closed.

The provided C++ code includes two algorithms to find the nth Fibonacci number: an inefficient recursive approach and an efficient iterative approach. The execution times for finding the 120th Fibonacci number can be compared to analyze the performance difference between the two algorithms.

Here's the C++ code to solve the Fibonacci number problem using both an inefficient and an efficient algorithm. We'll also measure the execution time for finding the 120th Fibonacci number using both approaches.

```cpp

#include <iostream>

int fibonacci(int n) {

   if (n <= 1)

       return n;

   else

       return fibonacci(n - 1) + fibonacci(n - 2);

}

int main() {

   int n = 120;

   // Measure execution time

   clock_t startTime = clock();

   int result = fibonacci(n);

   clock_t endTime = clock();

   double elapsedTime = double(endTime - startTime) / CLOCKS_PER_SEC;

   std::cout << "Fibonacci(" << n << ") = " << result << std::endl;

   std::cout << "Execution time: " << elapsedTime << " seconds" << std::endl;

   return 0;

}

```

```cpp

#include <iostream>

int fibonacci(int n) {

   int prev = 0;

   int curr = 1;

   for (int i = 2; i <= n; i++) {

       int temp = curr;

       curr += prev;

       prev = temp;

   }

   return curr;

}

int main() {

   int n = 120;

   // Measure execution time

   clock_t startTime = clock();

   int result = fibonacci(n);

   clock_t endTime = clock();

   double elapsedTime = double(endTime - startTime) / CLOCKS_PER_SEC;

   std::cout << "Fibonacci(" << n << ") = " << result << std::endl;

   std::cout << "Execution time: " << elapsedTime << " seconds" << std::endl;

   return 0;

}

```

Note: Both algorithms assume the Fibonacci sequence starts with F(0) = 0 and F(1) = 1.

The ladder reaches up to the side of the building at a height of about 5.9 feet. Rounded to one decimal place, the answer is 5.9 ft.

Trigonometric equations are equations that involve one or more trigonometric functions (such as sine, cosine, tangent, etc.) of one or more variables. The goal is usually to solve for one or more unknowns in terms of the given trigonometric functions and their arguments. These types of equations arise naturally in a variety of applications, such as physics, engineering, and geometry.

The ladder, the wall, and the ground form a right triangle, where the ladder is the hypotenuse, the wall is the adjacent side, and the ground is the opposite side. We know the length of the ladder (29 feet) and the angle between the ladder and the ground (81 degrees). We want to find the height the ladder reaches up to the side of the building (the length of the adjacent side).

We can use the cosine function, which relates the adjacent side to the hypotenuse and the angle between them:

cos(81) = adjacent/hypotenuse

We can rearrange this equation to solve for the adjacent side:

adjacent = hypotenuse * cos(81)

Plugging in the values we have:

adjacent = 29 * cos(81)

Using a calculator, we get:

adjacent ≈ 5.9

Therefore, the ladder reaches up to the side of the building at a height of about 5.9 feet. Rounded to one decimal place, the answer is 5.9 ft.

In this scenario, we are given a string that is 2.3 meters long and under a tension of 26 N. Additionally, a pulse travels the length of the string in 54 ms.

When a pulse travels through a string, it causes the string to vibrate and move. The tension of the string determines how quickly the pulse can travel and how far it can go. In this case, the tension of 26 N is relatively high, which means that the pulse can travel quickly and over a significant distance.
The fact that the pulse travels the length of the string in 54 ms tells us something about the speed of the pulse. We can use the formula speed = distance / time to calculate the speed of the pulse. In this case, the distance is the length of the string, which is 2.3 m. The time is 54 ms, or 0.054 s.
So, speed = distance / time = 2.3 m / 0.054 s = 42.59 m/s.
We now know the speed of the pulse, but what about the tension and length of the string? We can use the formula v = sqrt(T/μ) to calculate the speed of a pulse in a string, where v is the speed of the pulse, T is the tension of the string, and μ is the mass per unit length of the string.
Rearranging this formula, we get T = μv^2. We can use this formula to find the tension of the string. Plugging in the values we know, we get:
T = μv^2 = (mass per unit length of string) * (speed of pulse)^2
We don't know the mass per unit length of the string, but we can find it using the formula μ = m / L, where m is the mass of the string and L is its length.
Assuming the string has a uniform density, we can calculate its mass using the formula m = ρAL, where ρ is the density of the string, A is its cross-sectional area, and L is its length.
We don't know the cross-sectional area, but we can make a rough estimate based on the thickness of the string. Assuming the string has a circular cross-section, we can use the formula A = πr^2, where r is the radius of the string.
Again, we don't know the radius of the string, but we can make a rough estimate based on its diameter. Assuming the string has a diameter of 2 mm, its radius is 1 mm, or 0.001 m.
Plugging in these values, we get:
A = π(0.001 m)^2 = 7.85 x 10^-7 m^2
m = ρAL = (density of string) * (cross-sectional area) * (length of string)
  = (density of string) * (7.85 x 10^-7 m^2) * (2.3 m)
We don't know the density of the string, but assuming it is made of nylon or a similar material, its density is around 1100 kg/m^3. Plugging in this value, we get:
m = 2.039 x 10^-3 kg
μ = m / L = 2.039 x 10^-3 kg / 2.3 m = 8.86 x 10^-4 kg/m
Now we can use the formula T = μv^2 to find the tension of the string. Plugging in the values we know, we get:
T = μv^2 = (8.86 x 10^-4 kg/m) * (42.59 m/s)^2 = 159.3 N
So the tension of the string is 159.3 N, which is much higher than the original tension of 26 N. This makes sense, since the pulse travels quickly and over a significant distance, indicating that the tension must be high.

The derivative \(\( y' \)\) of the implicit function \(\( y^2 - xy = -2 \)\) is 0, indicating a constant slope with no change in relation to \(\( x \)\).

To find \(\( y' \)\)for the implicit function \(\( y^2 - xy = -2 \)\), we can differentiate both sides of the equation with respect to \(\( x \)\) using the chain rule. Let's go step by step:

Differentiating \(\( y^2 \)\) with respect to \(\( x \)\) using the chain rule:

\(\[\frac{d}{dx}(y^2) = 2y \cdot \frac{dy}{dx}\]\)

Differentiating \(\( xy \)\) with respect to \(\( x \)\) using the product rule:

\(\[\frac{d}{dx}(xy) = x \cdot \frac{dy}{dx} + y \cdot \frac{dx}{dx} = x \cdot \frac{dy}{dx} + y\]\)

Differentiating the constant term (-2) with respect to \(\( x \)\) gives us zero since it's a constant.

So, the differentiation of the entire equation is:

\(\[2y \cdot \frac{dy}{dx} - (x \cdot \frac{dy}{dx} + y) = 0\]\)

Now, let's rearrange the terms:

\(\[(2y - y) \cdot \frac{dy}{dx} - x \cdot \frac{dy}{dx} = 0\]\)

Simplifying further:

\(\[y \cdot \frac{dy}{dx}\) \(- x \cdot \frac{dy}{dx} = 0\]\)

Factoring out:

\(\[(\frac{dy}{dx})(y - x) = 0 \]\)

Finally, solving:

\(\[\frac{dy}{dx} = \frac{0}{y - x} = 0\]\)

Therefore, the derivative \(\( y' \)\) of the given implicit function is 0.

The approximate probability that the random sample of 50 will contain 38% or more orange candies is 0.966 or about 96.6%.

The number of orange candies in a sample of 50 candies as a binomial random variable with n = 50 and p = 0.30, p is the probability of selecting an orange candy.

The probability that the sample contains 38% or more orange candies, we need to calculate the cumulative probability of the binomial distribution from x = 0 to x = 19, and subtract it from 1.

Here, x is the number of orange candies in the sample, and 19 is the largest integer less than or equal to 0.38 × 50=19.

Using a binomial calculator or software, we can find that the cumulative probability of the binomial distribution from x = 0 to x = 19 is approximately 0.034.

The probability that the sample contains 38% or more orange candies is approximately:

1 - 0.034 = 0.966
