sin(2x) = sin(x)

sin(2x) - sin(x) = 0

2*sin(x)*cos(x) - sin(x) = 0

sin(x)*(2cos(x) - 1) = 0

sin(x) = 0 or 2cos(x)-1 = 0

sin(x) = 0 or cos(x) = 1/2

Using the unit circle, the solutions to sin(x) = 0 are x = 0, x = pi, x = 2pi

Also, the solutions to cos(x) = 1/2 are x = pi/3, x = 5pi/3

So the entire solution set on the interval [0,2pi] is {0, pi/3, pi, 5pi/3, 2pi} when written in increasing order.

All solutions to the equation in the interval [0, 2\(\pi\)]  is  {0, \(\frac{\pi }{3}, \pi , \frac{5\pi }{3} ,2\pi\)}.

A solution is an assignment of values to the unknown variables that makes the equality in the equation true.

As sin2x = 2 sinx cosx,

sin2x = sinx is equivalent to

2 sinx cosx = sinx or 2 sinx cosx − sinx = 0 or

sinx (2cosx − 1) = 0 i.e.

either sinx = 0 and x = 0, π, 2π

or 2cosx − 1 = 0 i.e. cosx = \(\frac{1}{2}\) i.e. x = \(\frac{\pi }{3} , \frac{5\pi }{3}\)

Hence, solution to an equation is x = {0, \(\frac{\pi }{3}, \pi , \frac{5\pi }{3} ,2\pi\)}

The equation that represents the exponential function passing through the points (-2, 1) and (2, 16) is: y = 4(2)^x

To write the exponential equation that passes through the points (-2, 1) and (2, 16), we can use the general form of an exponential function:

y = ab^x

Where y is the dependent variable, x is the independent variable, a is the initial value or y-intercept, and b is the base of the exponential function.

Step 1: Determine the value of a.

To find the value of a, substitute the coordinates of one of the given points into the equation. Let's use (-2, 1):

1 = ab^(-2)

Step 2: Determine the value of b.

To find the value of b, substitute the coordinates of the other given point into the equation. Let's use (2, 16):

16 = ab^2

Step 3: Solve the system of equations.

We now have a system of two equations with two unknowns (a and b):

1 = ab^(-2)

16 = ab^2

We can solve this system of equations to find the values of a and b. To do this, divide the second equation by the first equation:

16 / 1 = (ab^2) / (ab^(-2))

16 = b^4

Taking the fourth root of both sides, we get:

b = ±2

Step 4: Substitute the value of b back into one of the original equations to solve for a.

Let's substitute b = 2 into the first equation:

1 = a(2)^(-2)

1 = a / 4

a = 4

Alternatively, if we had chosen b = -2, we would have obtained a = -4, and the equation would be:

y = -4(-2)^x

Both equations represent exponential functions that pass through the given points.

The formula for finding slope is expressed as

slope = (y2 - y1)/(x2 - x1)

where

y2 and y1 are final and initial values of the y coordinates respectively

x2 and x1 are final and initial values of the x coordinates respectively

Considering line PQ,

x1 = - 6, y1 = 16

x2 = 2, y2 = - 4

Slope = (- 4 - 16)/(2 - - 6) = - 20/8

Slope = - 2.5

Considering line RS,

x1 = - 6, y1 = 14

x2 = - 2, y2 = 4

Slope = (4 - 14)/(- 2 - - 6) = - 10/4

Slope = - 2.5

If the slope of two lines are equal, it means that they are parallel. We can see that the slopes of PQ and RS are equal. Thus,

Line PQ is parallel to line RS

The answer depends on the specific row and the number of students who like both dodgeball and ping pong in that row.

To find the relative frequency by row of students who like both dodgeball and ping pong, we need to look at the row where both of these activities are listed. Let's assume that this row is labeled "Dodgeball and Ping Pong."

We then need to divide the number of students who like both activities by the total number of students in that row. This will give us the relative frequency.

If we assume that there are 100 students in this row, and 22 of them like both dodgeball and ping pong, then the relative frequency would be:

0.22

If the row had 50 students and 20 of them liked both activities, then the relative frequency would be:

0.40

If the row had 75 students and 36 of them liked both activities, then the relative frequency would be:

0.48

If the row had 80 students and 47 of them liked both activities, then the relative frequency would be:

0.59

So, the answer depends on the specific row and the number of students who like both dodgeball and ping pong in that row.

The prefrontal cortex is responsible for regulating higher cognitive functioning of the brain.

What is prefrontal cortex?

In the frontal lobe of the brain, there is a structure called the prefrontal cortex. It carries out cognitive functions like memory, attention, planning, flexibility, etc. It is regarded as the region of the brain that develops the least quickly

Prefrontal cortex is located in the frontal lobe.

The prefrontal cortex is responsible for regulating higher cognitive functioning of the brain.

Mid-twenties is when it reaches maturity. This explains why teenagers are more likely to establish harmful behaviours than younger kids and why adults are better at planning and thinking. An attention deficit and trouble remembering details can be brought on by prefrontal cortex (PFC) damage. Moreover, it may result in psychological changes, a diminished capacity for feeling, and bodily impairments associated with daily activities.

c = -10

Step-by-step explanation:

Hello!

According to the question we need to solve for c in the equation -49 = 2c - 29

-49 = 2c - 29

Flip the equation

2c - 29 = -49

Add 29 to both sides

2c - 29 + 29 = -49 + 29

2c = -20

Divide both sides by 2 to single out the variable

2c/2 = -20/2

c = -10

So, the value of c is -10

To find the maximum and minimum values of the function f(x, y) = exy subject to x^3 + y^3 = 54, we need to use the method of Lagrange multipliers.

Let's define g(x,y) = x^3 + y^3 - 54 as our constraint equation. Then, the Lagrangian function is:

L(x,y,λ) = exy + λ(x^3 + y^3 - 54)

Taking the partial derivatives with respect to x, y, and λ and setting them equal to 0, we get:

∂L/∂x = ey + 3λx^2 = 0
∂L/∂y = ex + 3λy^2 = 0
∂L/∂λ = x^3 + y^3 - 54 = 0

From the first two equations, we can solve for x and y in terms of λ:

x = (-ey/3λ)^(1/2)
y = (-ex/3λ)^(1/2)

Substituting these expressions into the third equation, we get:

(-ex/3λ)^(3/2) + (-ey/3λ)^(3/2) - 54 = 0

We can solve for λ in terms of e:

λ = e^(2/3)/(2*3^(1/3))

Substituting this back into the expressions for x and y, we get:

x = 3^(1/6)*e^(1/3)/y^(1/2)
y = 3^(1/6)*e^(1/3)/x^(1/2)

Now, we can find the critical points by setting the partial derivatives of f(x,y) = exy equal to 0:

∂f/∂x = ey(x) = 0
∂f/∂y = ex(y) = 0

From the expressions for x and y above, we see that x and y cannot be 0. Therefore, the only critical point is when e^(xy) = 0, which is not possible.

Thus, the function has no critical points in the interior of the region defined by the constraint equation. This means that the maximum and minimum values of the function must occur on the boundary of the region.

We can parametrize the boundary using polar coordinates:

x = 3^(1/3)cos(t)
y = 3^(1/3)sin(t)

Substituting these into f(x,y) = exy, we get:

f(t) = e^(3^(2/3)cos(t)sin(t))

To find the maximum and minimum values of f(t), we can take the derivative with respect to t and set it equal to 0:

f'(t) = 3^(2/3)e^(3^(2/3)cos(t)sin(t))(cos(2t) - sin(2t)) = 0

The solutions to this equation are t = π/4 and t = 5π/4.

Substituting these values back into f(t), we get:

f(π/4) = f(5π/4) = e^(3^(2/3))

Therefore, the maximum and minimum values of the function f(x,y) = exy subject to x^3 + y^3 = 54 are both e^(3^(2/3)).

Therefore, in about 15 years and 2 months, the senior class will have about 100 students.

An equation is a statement that expresses the equality of two mathematical expressions using mathematical symbols such as variables, numbers, and mathematical operations. The equality is represented by an equal sign "=" between the two expressions. Equations are used to represent mathematical relationships and solve problems in various fields such as physics, chemistry, engineering, and economics.

Given by the question.

Let P be the initial population of the senior class in the high school, and r be the rate of decrease in population per year (in decimal form).

Then, we can write the following equation to represent the situation:

P\((1-r)^{n}\) = 100

We know that the current population of the senior class is 320, so we can substitute these values into the equation:

320\((1-0.07)^{n}\) = 100

Simplifying the equation, we get:

\(0.93^{n}\) = 0.3125

Taking the natural logarithm of both sides, we get:

n ln (0.93) = ln (0.3125)

Dividing both sides by ln (0.93), we get:

n = ln (0.3125) / ln (0.93)

Using a calculator, we find that n is approximately equal to 15.21 years.

The probability that strictly more than 5 customers arrive in a given hour is approximately 0.8335 (or 83.35%).

Let's denote the random variable representing the number of customers arriving in an hour as X, which follows a Poisson distribution with a mean of 11.

To calculate P(X > 5), we need to sum the probabilities of X being greater than 5 for all possible values of X greater than 5.

P(X > 5) = 1 - P(X ≤ 5)

Using the Poisson distribution formula, we can calculate the cumulative probability of X being less than or equal to 5:

P(X ≤ 5) = Σ [e^(-λ) * (λ^k) / k!] for k = 0 to 5

Substituting the mean λ = 11 into the formula, we get:

P(X ≤ 5) = Σ [e^(-11) * (11^k) / k!] for k = 0 to 5

P(X ≤ 5) ≈ 0.1665

Finally, calculating P(X > 5) using the complement rule:

P(X > 5) = 1 - P(X ≤ 5)

P(X > 5) ≈ 1 - 0.1665

P(X > 5) ≈ 0.8335

The current age of Rita is 17 years and Cheryl is 7 years respectively, according to mentioned data.

Let us assume Rita's present age be x and Cheryl's age be y.

Rita's age two years ago = 3 × Cheryl's age two years ago

x - 2 = 3 (y - 2) - equation 1

Rita's age after three years = 3 × Cheryl's age after three years

x + 3 = 2 (y + 3) - equation 2

Solving equation 1

x - 2 = 3y - 6

x = 3y - 6 + 2

x = 3y - 4

Solving equation 2

x + 3 = 2y + 6

x = 2y + 6 - 3

x = 2y + 3

Keep the value of x from equation 2 in equation 1

2y + 3 = 3y - 4

Rearranging the equation

3y - 2y = 3 + 4

y = 7

Keep the value of y in equation x = 2y + 3

x = 2×7 + 3

x = 14 + 3

x = 17

So, Cheryl's and Rita's age is 7 and 17 years respectively.
