Answer:

x = {-8 - √10, -8 + √10}     exact answer

x = {-11.16, -4.84}     decimal approximation

Step-by-step explanation:

2(x + 8)²+ 9 = 29

Subtract 9 from both sides

2(x + 8)² = 20

Divide both sides by 2

(x + 8)² = 10

Take the square root of both sides

x + 8 = ±√10

Subtract 8 from both sides

x = -8 ± √10

x = {-8 - √10, -8 + √10}     exact answer

x = {-11.16, -4.84}     decimal approximation

The equation of a nonlinear function is D) y=x^2+15.

A nonlinear function is a function that does not have a constant rate of change. Option A (y=25) is a linear function because it has a constant rate of change of 0. Option B (y=x-3/4) is also a linear function because it can be simplified to y = x - 0.75, which has a constant rate of change of 1.

Option C (y=10x) is also a linear function because it has a constant rate of change of 10. Option D (y=x^2+15) is a nonlinear function because its rate of change is not constant. The rate of change increases as x increases, which can be seen from the graph of the function as a curve, not a straight line.

Therefore, option D is the equation of a nonlinear function.

Answer:the answer to this is 16x -16y=5.

step by step explanation:.

4x+8y=24y=-12x+5

= 4x+13x+8y-24y=5.

16x - 16y =5.

The surface area of the piecewise smooth surface that is the boundary of the region enclosed by the paraboloids is For the first paraboloid, \(f(x, y) = 8 - 5x^2 - 5y^2: A1 = ∬√(1 + (-10x)^2 + (-10y)^2) dA\) and for the second paraboloid,\(f(x, y) = 3x^2 + 3y^2: A2 = ∬√(1 + (6x)^2 + (6y)^2) dA.\)

To find the surface area of the piecewise smooth surface which is the boundary of the region enclosed by the paraboloids, we need to calculate the surface area of each paraboloid and then find their intersection curve.

The first paraboloid, \(z = 8 - 5x^2 - 5y^2\), represents an upward-opening paraboloid with its vertex at (0, 0, 8) and a maximum value of 8. The second paraboloid, \(z = 3x^2 + 3y^2\), represents a downward-opening paraboloid with its vertex at (0, 0, 0) and a minimum value of 0.

To find the intersection curve between these two paraboloids, we set the two equations equal to each other:

\(8 - 5x^2 - 5y^2 = 3x^2 + 3y^2\)

Simplifying the equation, we have:

\(8 - 8x^2 - 8y^2 = 0\)

Dividing both sides by 8, we get:

\(1 - x^2 - y^2 = 0\)

This equation represents a circle of radius 1 centered at the origin (0, 0, 0).

To calculate the surface area of each paraboloid, we can use the surface area formula for a general surface z = f(x, y):

\(A = ∬√(1 + (f_x)^2 + (f_y)^2) dA\)

For the first paraboloid, \(f(x, y) = 8 - 5x^2 - 5y^2: A1 = ∬√(1 + (-10x)^2 + (-10y)^2) dA\)

Similarly, for the second paraboloid, \(f(x, y) = 3x^2 + 3y^2: A2 = ∬√(1 + (6x)^2 + (6y)^2) dA.\)

Therefore, integrating these surface area formulas over their respective domains will give the total surface area of the piecewise smooth surface.

To find a probability you take the specific parameters divided by the entire set of possibilities.

For example, the specific parameter here is that the drink must be a medium, (no matter the temperature). So, we would add 48 and 12 to get 60.

And we know that the total number of orders is 100.

So, we should divide 60 by 100, and we get 60%.

1)The answer to the first question is A. 68%. 2)The statement that is not true about a normal distribution is: D. A normal distribution can be skewed either to the left or to the right.

The Empirical Rule states that for a bell-shaped distribution (which is assumed to be a normal distribution), approximately 68% of measurements fall within one standard deviation of the mean, approximately 95% fall within two standard deviations of the mean, and approximately 99.7% fall within three standard deviations of the mean. Therefore, the answer to the first question is A. 68%.

Regarding the second question, the statement that is not true about a normal distribution is:

D. A normal distribution can be skewed either to the left or to the right.

A normal distribution is symmetric and not skewed. Skewness refers to the asymmetry of the distribution, and a normal distribution by definition does not exhibit skewness. Therefore, the answer is D. A normal distribution cannot be skewed either to the left or to the right.

Compound interest is the interest earned on both the initial principal amount and any accumulated interest from previous periods. It is calculated by applying a percentage rate to the total balance, including interest, and is commonly used in savings accounts, loans, and investments.

Felipe's balance at the end of the year can be calculated using the formula for compound interest:

A = P(1 + r/n)^(nt)

Where A is the ending balance, P is the initial balance, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

For the first 4 months, the introductory APR of 5.9% is equivalent to a monthly interest rate of 0.59%/12 = 0.0492. So, Felipe's balance after the first 4 months would be:

A1 = 3700(1 + 0.0492/1)^(1*4/12) = 3772.96

After the first 4 months, the standard APR of 17.2% is equivalent to a monthly interest rate of 1.72%/12 = 0.0143. So, Felipe's balance for the remaining 8 months would be:

A2 = 3772.96(1 + 0.0143/1)^(1*8/12) = 3976.55

Therefore, Felipe's balance at the end of the year would be:

A = 3976.55

This assumes that Felipe makes no payments or new purchases during the year and that there are no late payment fees. It is important for Felipe to make payments on time to avoid additional fees and interest charges. Additionally, if Felipe makes new purchases on the card, the balance will increase and the interest charged will be calculated based on the new balance.

To approximate the value of π using the Leibniz method, you can write a Python program that calculates the sum of the series up to a certain number of terms. The more terms you include in the series, the closer the approximation will be to the actual value of π.

The Leibniz method, also known as the Leibniz formula for π, is an infinite series that converges to π/4. The formula is given by:

π = 4(1 - 1/3 + 1/5 - 1/7 + 1/9 - 1/11 + ...)

To approximate π, you can calculate the sum of the series up to a certain number of terms. The more terms you include, the more accurate the approximation will be.

In Python, you can write a program that iterates through the terms of the series and accumulates the sum. Here's an example of how you can implement it:

def approximate_pi(num_terms):

   pi = 0

   sign = 1

for i in range(1, num_terms*2, 2):

       term = sign * (1/i)

       pi += term

       sign *= -1

   return pi * 4

num_terms = 100000  # Choose the number of terms for the approximation

approximation = approximate_pi(num_terms)

In this example, we define the approximate_pi function that takes the number of terms as an argument. The function iterates from 1 to num_terms*2 with a step size of 2, representing the denominators of the series. The sign alternates between positive and negative to include the alternating addition and subtraction. Finally, we return the calculated sum multiplied by 4 to obtain the approximation of π.

By increasing the value of num_terms, you can achieve a more accurate approximation of π. However, keep in mind that the Leibniz method converges slowly, so a large number of terms may be needed for a precise approximation.

Answer:

m

Step-by-step explanation:

Vertically compressing the exponential parent function f(x) = 2^x by a factor of 3 means multiplying every function value by 1/3, resulting in a steeper and narrower curve closer to the x-axis.

If we vertically compress the exponential parent function f(x) = 2^x by a factor of 3, it means that every point on the graph of the function will be compressed closer to the x-axis. In other words, the function values will be multiplied by 1/3.

Let's consider a point on the original exponential function, (x, f(x)). After the vertical compression, this point will have the coordinates (x, (1/3)f(x)). For example, if f(x) = 8 for some x, after compression, the corresponding point will be (x, (1/3)(8)) = (x, 8/3).

This vertical compression affects all points on the graph uniformly, resulting in a steeper and narrower curve compared to the original exponential function.

The y-values of the compressed function will be one-third of the y-values of the original function for each x-value. Therefore, the graph will be squeezed vertically, with the y-values closer to the x-axis.

then

\(k\perp l\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\k\ ||\ l\iff m_1=m_2\)

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

We have:

\(y=-\dfrac{3}{4}x-3\to m_1=-\dfrac{3}{4}\)

Let

\(y=m_2x+b_2\)

Therefore

\(m_2=-\dfrac{1}{-\frac{3}{4}}=\dfrac{4}{3}\Rightarrow y=\dfrac{4}{3}x+b_2\)

The probability that not a single invitation landed in the correct envelope is P(n) = D(n) / n! , where D(n) is the number of derangements of n objects.

The number of derangements of n objects is denoted by D(n).

The first few values of D(n) are given below: D(1) = 0 (trivially)D(2)

= 1 (the two objects must switch places)D(3)

= 2 (out of the six possible permutations, only two are derangements)D(4)

= 9 (out of the 24 possible permutations, nine are derangements)D(5)

= 44 (out of the 120 possible permutations, 44 are derangements)

The formula for the number of derangements is D(n) = n! × (1/0! - 1/1! + 1/2! - 1/3! + ··· + (-1)^n / n!), where n! is the factorial of n, 0! = 1 by definition, and (-1)^n is (-1) raised to the power of n.

Hence, we can find the probability that not a single invitation landed in the correct envelope as P(n) = D(n) / n!.

Thus, the probability that not a single invitation landed in the correct envelope is P(n) = D(n) / n! , where D(n) is the number of derangements of n objects.

The commission earned are R41123.17, R47931.67 and R15024.09

The VAT included prices are given as:

R271 800,00; R316 800,00 and R99 300,00.

The VAT rate is 12.36%.

So, the price before VAT is calculated as:

VAT included = Price without VAT * (1 + 12.36%)

This gives

VAT included = Price without VAT * 1.1236

So, we have:

Price without VAT = VAT included/1.1236

For the three cars, we have:

Price without VAT = R271 800.00/1.1236 = R241901

Price without VAT = R316800.00 /1.1236 = R281951

Price without VAT = R99300.00/1.1236 = R88377

Hence, the prices of the cars before VAT was added are R241901, R281951 and R88377

This is calculated as:

Commission = Price * 17%

So, we have:

Commission = R241901 * 17% = R41123.17

Commission = R281951 * 17% = R47931.67

Commission = R88377 * 17% = R15024.09
