find doubling time : q=100e.5x . round answer to 4-decimal places.

Let Charles age be x

Adam age will be 5x  

8 years later , add 8 to both expressions

Charles age = x+8

Adam age = 5x+8

add their ages and equate them to twice adam's present age 2*5x

x+8+5x+8 = 2*5x

6x+16=10x

4x=16

x=4

x = Charles' age

Adam's age  5x = 5(4) = 20

Answer:

h = -3y + 2x

Step-by-step explanation:

Add 4x to both sides of the equation.

2h = −6y + 4x

Divide each term in 2h = −6y + 4x by 2 and simplify.

Divide each term in 2h = −6y + 4x by 2.

2h/2 = -6y/2 + 4x/2

Simplify the left side.

h = −6y/2 + 4x/2

Simplify the right side.
Simplify each term.
Cancel the common factor of −6 and 2.

h = -3y+2(2x)/2

Cancel the common factors.
Factor 2 out of 2.

h = -3y+2(2x)/2(1)
Cancel the common factor

h = -3y+2(2x)/2(1)
Rewrite the expression
h = -3y + 2x/1

Divide 2x by 1.
h = -3y + 2x

hopefully its right LOLZ

Answer:

60

Step-by-step explanation:

the total cupcakes are:

(57/95) . 100 = 60

The x-coordinate of the vertex is 0.  the corresponding y-coordinate (the maximum area), we can substitute x = 0 into the equation A(x) = -x^2 + 40: A(0) = -(0)^2 + 40 = 40.

To find the dimensions that will create the maximum area of the prop section, we need to analyze the given equation A = -x^2 + 40. The equation represents a quadratic function in the form of A = -x^2 + 40., where A represents the area of the prop section and x represents the dimension.

The quadratic function is in the form of a downward-opening parabola since the coefficient of is negative (-1 in this case). The vertex of the parabola represents the maximum point on the graph, which corresponds to the maximum area of the prop section.

To determine the x-coordinate of the vertex, we can use the formula x = -b / (2a), where the quadratic equation is in the form Ax^2 + Bx + C and a, b, and c are the coefficients. In this case, the equation is -x^2 + 40, so a = -1 and b = 0. Plugging these values into the formula, we get x = 0 / (-2 * -1) = 0.

Therefore, the x-coordinate of the vertex is 0. To find the corresponding y-coordinate (the maximum area), we can substitute x = 0 into the equation  A(x) = -x^2 + 40: A(0) = -(0)^2 + 40 = 40.

Hence, the equation that reveals the dimensions that will create the maximum area of the prop section is A = 40. This means that regardless of the dimension x, the area of the prop section will be maximized at 40 units.

Answer:

It's 6.

Step-by-step explanation:

6- 1, 2, 3, 6

36- 1, 2, 3, 4, 6

The greatest common factor of 6 and 36 is 6

Given data ,

Let the first number be represented as p

where the value of p = 6

Let the second number be represented as q

where the value of q = 36

To find the greatest common factor (GCF) of 6 and 36, we need to determine the largest positive integer that can divide both numbers evenly.

To begin, we can list the factors of each number:

Factors of 6 : 1 , 2 , 3 , 6

Factors of 36 : 1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , 36

From the lists, we can see that both 6 and 36 share a common factor of 6. The GCF of 6 and 36 is therefore 6, as it is the largest number that can evenly divide both 6 and 36.

Answer:

284/3 πx³

Step-by-step explanation:

Volume of a cylinder is expressed as shown:

V = πr²h

r is the radius of the cylinder

r = diameter/2

r = 8x/2

r = 4x

Height of the cylinder = 6x

Volume of the roll with out the hole

V = π(4x)²(6x)

V = 16x²π(6x)

V = 96πx³

The hole in the middle will be a solid sphere with diameter 2x (radius will be x)

Volume of the hole = 4/3πr³

Volume if the hole = 4/3πx³

Volume of the toilet paper roll = volume of the roll without a hole - volume of the hole

= 96πx³ - 4/3πx³

= (96-4/3)πx³

= 284/3 πx³

The single exponential smoothing forecast for semester 7 using an alpha value of 0.35 is 158.75. The forecast bias is -1.25, the mean absolute deviation (MAD) is 10.5, and the mean squared error (MSE) is 134.875.

To calculate the single exponential smoothing forecast, we use the formula: Ft = Ft-1 + a(At-1 – Ft-1), where Ft represents the forecast for semester t, At represents the actual enrollment for semester t, and a is the smoothing factor (alpha value).

In this case, the initial forecast for semester 1 is given as 90. Plugging in the values, we can calculate the forecast for each subsequent semester using the formula.

For example, for semester 2, the forecast is 90 + 0.35(87 - 90) = 90 + 0.35(-3) = 89.05. Continuing this process, we find the forecast for semester 7 to be 158.75.

The forecast bias represents the difference between the sum of the forecast errors and zero, divided by the number of observations. In this case, the forecast bias is calculated as (-1.25) / 6 = -0.208.

The mean absolute deviation (MAD) measures the average magnitude of the forecast errors. It is calculated by summing the absolute values of the forecast errors and dividing by the number of observations.

In this case, the MAD is (|1.25| + |0.95| + |3.95| + |0.55| + |0.25| + |1.25|) / 6 = 10.5.

The mean squared error (MSE) measures the average of the squared forecast errors. It is calculated by summing the squared forecast errors and dividing by the number of observations.

In this case, the MSE is ((1.25)^2 + (0.95)^2 + (3.95)^2 + (0.55)^2 + (0.25)^2 + (1.25)^2) / 6 = 134.875.

These values provide an indication of the accuracy and bias of the forecasting method. A forecast bias of -1.25 indicates a slight underestimation of enrollment, on average, over the six semesters.

The MAD of 10.5 suggests that, on average, the forecast deviates from the actual enrollment by approximately 10.5 students. The MSE of 134.875 indicates the average squared error of the forecasts, providing a measure of the overall forecasting accuracy.

(A) The absolute value of the matrix B is 24. (B) The product of 2AB and the absolute value of matrix A is 288.

The question requires finding the absolute value of matrix B without using direct computations and calculating the product of 2AB and the absolute value of matrix A.

The probability of x not lies in BD = 0.264

Given that,

Number of points between AE = 19

Number of points between BD = 14

Then number of total outcomes = 19

Thus, favorable outcomes are those that satisfy an event's condition, while probability refers to how probable something is to occur.

Then number of favorable outcomes = 14

Since we know that,

Probability is the ratio of number of favorable outcomes and total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.

Therefore,

Probability = (favorable outcomes)/(total outcomes)

Then,

P(X in BD)  = 14/19

To apply the Central Limit Theorem, the following condition is necessary:

1. The random sample should be selected from a population that has a finite mean (μ) and a finite standard deviation (σ).

In this case, the population mean is given as $75 and the population standard deviation is given as $5. Since both the mean and standard deviation are finite, the condition for applying the Central Limit Theorem is satisfied.

tan(41π/36) can be written in terms of the tangent of a positive acute angle as (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

To express tan(41π/36) in terms of the tangent of a positive acute angle, we need to find an angle within the range of 0 to π/2 that has the same tangent value.

First, let's simplify 41π/36 to its equivalent angle within one full revolution (2π):

41π/36 = 40π/36 + π/36 = (10/9)π + (1/36)π

Now, we can rewrite the angle as:

tan(41π/36) = tan((10/9)π + (1/36)π)

Next, we'll use the tangent addition formula, which states that:

tan(A + B) = (tan(A) + tan(B)) / (1 - tan(A)tan(B))

In this case, A = (10/9)π and B = (1/36)π.

tan(41π/36) = tan((10/9)π + (1/36)π) = (tan((10/9)π) + tan((1/36)π)) / (1 - tan((10/9)π)tan((1/36)π))

Now, we need to find the tangent values of (10/9)π and (1/36)π. Since tangent has a periodicity of π, we can subtract or add multiples of π to get equivalent angles within the range of 0 to π/2.

For (10/9)π, we can subtract π to get an equivalent angle within the range:

(10/9)π - π = (1/9)π

Similarly, for (1/36)π, we can add π to get an equivalent angle:

(1/36)π + π = (37/36)π

Now, we can rewrite the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Since we are looking for an angle within the range of 0 to π/2, we can further simplify the expression as:

tan(41π/36) = (tan((1/9)π) + tan((37/36)π)) / (1 - tan((1/9)π)tan((37/36)π))

Therefore, tan(41π/36) can be written in terms of the tangent of a positive acute angle as the expression given above.
