Answer:

T(t) = f(t) + g(t)

Step-by-step explanation:

The function which represents the total amount of money Henri will have in t years is the function obtained using an addition operation in the two defied functions, f(t) and g(t) ; total amount saved in shoe box plus the total compounded amount in savings account

Total amount of money in t years, T(t) ;

T(t) = 120t + 1,500(1.09)^t

f(t) = 120t

g(t) = 1,500(1.09)^t

Hence,

T(t) = f(t) + g(t)

The five-number summary, as shown in the MINITAB output, includes the minimum value, Q1 (the first quartile), the median (Q2), Q3 (the third quartile), and the maximum value.

To calculate the interquartile range (IQR), we need to find the difference between Q3 and Q1. In this case, Q1 is 6 and Q3 is 11, so the IQR is 5.
To determine if there are any outliers in the data set, we can use the rule that any data points that are more than 1.5 times the IQR below Q1 or above Q3 are considered outliers. In this case, the lower limit would be 6 - (1.5 x 5) = -1.5 and the upper limit would be 11 + (1.5 x 5) = 18.5. Looking at the data in column 1, we can see that there are no values that fall outside of these limits, so there are no outliers in this set of data.
Using statistics software to calculate the five-number summary, IQR, and identify outliers is a quick and efficient way to analyze data. This information can provide valuable insights into the distribution of the data and help identify any potential issues or trends that need to be addressed.

The constant percent rate of change per year 33.5 %. So the correct option is A.

Growth factor is a mathematical concept that represents the amount by which a quantity increases or decreases over a period of time. It is usually expressed as a decimal or a percentage. A growth factor greater than 1 indicates an increase in the quantity, while a growth factor less than 1 indicates a decrease. A growth factor of 1 indicates no change in the quantity.

For example, if the population of a city is growing by 2% per year, the growth factor would be 1.02, since the population is increasing by 2% (0.02) every year. If the population was decreasing by 3% per year, the growth factor would be 0.97, since the population is decreasing by 3% (0.03) every year.

To find the constant percent rate of change per year, we need to rewrite the function D(m) in terms of years, and then find the annual growth factor.

First, we can divide m by 12 to get the time in years:

m/12 = y

Substituting this into the function D(m) gives:

D(m) = 845,000(\(1.013^{m}\)) = 845,000(\(1.013^{12y}\))

Now we have D(y) in terms of the annual growth factor b:

D(y) = 845,000(\(b^{y}\)), where b = 1.013¹²

To find the constant percent rate of change per year, we need to find the value of b-1 as a percent:

(b-1)*100

= (1.013¹² - 1)*100

= 33.5% (rounded to the nearest tenth)

Therefore, the answer is (A) 33.5%.

The coordinates of the triangle after enlarging it by a scale factor of 1.5 using (4, 4) as the center of enlargement include the following:

Coordinate A' = (-5, 4)

Coordinate B' = (13, -2)

Coordinate C' = (-2, -2)

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Next, we would have to dilate (enlarge) the coordinates of the pre-image of the given triangle by using a scale factor of 1.5 centered at the point (4, 4) by using this mathematical expression:

(x, y)  →  (k(x - a) + a, k(y - b) + b)

For coordinate A, we have;

Coordinate A = (-2, 4)  →  (1.5(-2 - 4) + 4, 1.5(4 - 4) + 4)

Coordinate A' = (-2, 4)  →  (-5, 4)

For coordinate B, we have;

Coordinate B = (-2, 0)  →  (1.5(-2 - 4) + 4, 1.5(0 - 4) + 4)

Coordinate B' = (-2, 0)  →  (13, -2)

For coordinate C, we have;

The product of three consecutive positive integers is always divisible by 6.

We can prove this statement using mathematical induction. The statement we want to prove is that the product of three consecutive positive integers is divisible by 6. To do this, we will use the induction hypothesis:

Let P(n) be the statement: The product of three consecutive positive integers starting with n is divisible by 6.

We will prove that P(n) is true for all natural numbers n.

Base Case: Let n = 1. Then the product of the three consecutive positive integers (1, 2, 3) is 6, which is divisible by 6. Therefore, P(1) is true.

Inductive Step: Assume that P(k) is true, where k is any natural number. We will now prove that P(k + 1) is also true.

The three consecutive positive integers starting with k + 1 are k + 1, k + 2, and k + 3. We can then rewrite the product of these three consecutive positive integers as follows:

(k + 1)(k + 2)(k + 3) = k3 + 3k2 + 6k + 6.

Since we assumed that P(k) is true, we know that k3 + 3k2 + 6k is divisible by 6. Therefore, the entire expression k3 + 3k2 + 6k + 6 is also divisible by 6. Since 6 is also added to this expression, we know that the product of three consecutive positive integers starting with k + 1 is divisible by 6. Therefore, P(k + 1) is true.

Since we have proven the base case and the inductive step, we have proven the statement for all natural numbers n. Therefore, the product of three consecutive positive integers is always divisible by 6.

Answer:

3.5 cm

Step-by-step explanation:

Perimeter of rectangle = 2 × (w + h)

w = 9.5 - 6 = 3.5 (cm)

The absolute value of the percent change in the volume of the cylinder is 20%.


When the radius of a right circular cylinder is decreased by 20%, its new radius becomes 0.8 times the original radius (1 - 0.20 = 0.8).

Likewise, when its height is increased by 25%, its new height becomes 1.25 times the original height (1 + 0.25 = 1.25).

The volume of a right circular cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height. Let V₁ be the original volume, and V₂ be the new volume after the changes.

V₁ = π(r)²(h) and V₂ = π(0.8r)²(1.25h)

V₂ = π(0.64r²)(1.25h) = 0.8πr²h

Thus, the new volume is 0.8 times the original volume. This represents a 20% decrease in volume (1 - 0.8 = 0.20 or 20%). So, the absolute value of the percent change in the volume of the cylinder is 20%.

In summary, decreasing the radius by 20% and increasing the height by 25% results in a 20% decrease in the volume of the right circular cylinder.

The solution after integration is  for y(x) is:\(y(x) = (1/4) x^{(-3)} x^5 - (1/3) e^{(3x)} + (1/3) e^(6)\)

Finding the integral, or total value, of a given function, is the subject of the area of mathematics known as integration. Finding a function's rate of change entails the differentiation procedure in reverse.

To handle issues like determining the area under a curve, figuring out the volumes of solids in revolution, resolving differential equations, and simulating physical processes, integration is employed in many branches of mathematics, science, and engineering.

Antiderivatives and numerical integration are the two basic methods for determining a function's integral. In contrast to numerical integration, which uses mathematical techniques to approximation the integral, antiderivatives entail finding a function whose derivative is identical to the original function.

To find the solution for y(x) given the differential equation X(dy/dx) + 3y = 2x^5, we can use the method of integrating factor. The integrating factor for this equation is given by e^(3x), so we can multiply both sides of the equation by this factor:

\(e^{(3x)} X \frac{dy}{dx} + 3e^{(3x)} y = 2x^5 e^{(3x)}\)

Integrating both sides with respect to x, we get:

\(e^{(3x)} y = (1/3) x^6 + C\)

where C is the constant of integration. To find the value of C, we use the initial condition y(2) = 1:

\((1/3) e^{(6)} + C = 1\)

Solving for C, we get:

\(C = 1 - (1/3) e^{(6)}\)

Finally, substituting C back into the equation for y, we get:

\(y(x) = (1/3) e^{(3x)} x^6 - (1/3) e^{(3x)} + (1/3) e^{(6)}\)

So the general solution for y(x) is:

\(y(x) = (1/4) x^{(-3)} x^5 - (1/3) e^{(3x)} + (1/3) e^{(6)}\)
