It will take approximately 7.54 years for the investment to be worth $900 if it is continuously compounded at 11% per year.
We can use the formula for continuous compounding to solve this problem:
[tex]A = Pe^{rt}[/tex]
where A is the amount after t years, P is the initial investment, r is the annual interest rate in decimal form, and e is the base of the natural logarithm.
In this case, P = $400, A = $900, r = 0.11, and we want to solve for t.
We can rewrite the formula as:
[tex]t = ln(A/P) / r[/tex]
Plugging in the values we get:
[tex]t = ln(900/400) / 0.11 = 7.54[/tex]
Therefore, it will take approximately 7.54 years for the investment to be worth $900.

Eight people are to be seated in a row of 8 chairs. In how many ways can these people be seated if two of them insist on sitting next to one another?
The final answer is 8*2=16 ways
Eight people are to be seated in a row of 8 chairs. In how many ways can these people be seated if two of them insist on sitting next to one another?
There are a couple of steps to solving this problem.
Step 1: Consider the two people who insist on sitting next to one another as one unit. This means that there are now 7 units to be seated in the 8 chairs.
Step 2: Calculate the number of ways that the 7 units can be seated in the 8 chairs. This is done using the formula n!/(n-r)!, where n is the number of chairs and r is the number of units. In this case, n=8 and r=7, so the formula is 8!/(8-7)!, or 8!/1!, which simplifies to 8.
Step 3: Calculate the number of ways that the two people who insist on sitting next to one another can be seated within their unit. There are 2! or 2 ways that they can be seated.
Step 4: Multiply the number of ways that the 7 units can be seated in the 8 chairs by the number of ways that the two people can be seated within their unit. This gives us the total number of ways that the 8 people can be seated if two of them insist on sitting next to one another.
So the final answer is 8*2=16 ways.

Correct tion for the circle with the following properties. Center (4,8), passes through (-10,-5)
The equation of a circle with center at (4, 8) and passing through (-10, -5) is [tex](x-4)^2 + (y-8)^2 = (6)^2.[/tex]
To find this equation, we need to use the distance formula: [tex]d = sqrt((x2-x1)^2 + (y2-y1)^2).[/tex]
We can substitute in the coordinates of the center of the circle and the point it passes through:
[tex]d = sqrt((-10-4)^2 + (-5-8)^2)[/tex]
[tex]d = sqrt( (6)^2 + (13)^2 )[/tex]
d = sqrt(36 + 169)
d = sqrt(205)
d = 14.2
Now, we have the radius of the circle. We can use this to form the equation of the circle:

Do segments with lengths 11, 12, and 20 form a triangle? If so, classify the triangle as acute, right, or obtuse?
Answer:
Yes, the segments with lengths 11, 12, and 20 can form a triangle.
To check this, we can use the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, we can check that:
11 + 12 > 20
11 + 20 > 12
12 + 20 > 11
Since all three inequalities are satisfied, the segments can form a triangle.
To classify the triangle, we can use the law of cosines, which relates the lengths of the sides of a triangle to the cosine of one of its angles. Specifically, for a triangle with sides a, b, and c and angle A opposite side a, we have:
c^2 = a^2 + b^2 - 2ab cos(A)
Using this formula, we can find the cosine of each angle and determine if the triangle is acute, right, or obtuse based on the values obtained.
For the given triangle, we have:
a = 11, b = 12, c = 20
cos(A) = (b^2 + c^2 - a^2) / (2bc) = (12^2 + 20^2 - 11^2) / (2 * 12 * 20) ≈ 0.714
Since cos(A) is positive and less than 1, the angle A is acute. Similarly, we can find the cosines of the other angles:
cos(B) = (c^2 + a^2 - b^2) / (2ca) ≈ 0.943
cos(C) = (a^2 + b^2 - c^2) / (2ab) ≈ -0.519
Since cos(B) and cos(C) are both positive and less than 1, angles B and C are also acute.
Therefore, the given triangle is acute.

Find the determinant. \[ \left|\begin{array}{ccc} d+b & d & d \\ d & d+b & d \\ d & d & d+b \end{array}\right| \]
The determinant of a 3x3 matrix can be found using the following formula:
\[ \left|\begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array}\right| = a(ei - fh) - b(di - fg) + c(dh - eg) \]
In this case, we can substitute the values from the given matrix into the formula:
\[ \left|\begin{array}{ccc} d+b & d & d \\ d & d+b & d \\ d & d & d+b \end{array}\right| = (d+b)((d+b)(d+b) - d^2) - d(d(d+b) - d^2) + d(d^2 - d(d+b)) \]
Simplifying the expression gives:
\[ = (d+b)(d^2 + 2bd + b^2 - d^2) - d(d^2 + bd - d^2) + d(d^2 - d^2 - bd) \]
\[ = (d+b)(2bd + b^2) - d(bd) + d(-bd) \]
\[ = 2bd^2 + 2b^2d + b^3 - bd^2 - bd^2 \]

The area of a classroom is 20 square meters. If the length is increased by 3 meters and the width is increased by 1 meter, the classroom will double in area. Determine the dimension of the new classroom.
The dimension of the new classroom is 8 meters of length and 5 meters of width.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given that,
Area of the classroom = 20 square meters
Let x be the length and y be the width of the classroom.
Area of a rectangular classroom = Length × Width.
So, we get an equation,
xy = 20
x = 20/y [Equation 1]
If length is increased by 3 meters and the width is increased by 1 meter, the classroom will double in area.
(x + 3) (y + 1) = 20 × 2
(x + 3) (y + 1) = 40 [Equation 2]
Substitute [Equation 1] in [Equation 2]
((20/y) + 3) (y + 1) = 40
Multiplying,
20 + 3y + (20/y) + 3 = 40
3y + (20/y) = 40 - 23
3y + (20/y) = 17
Multiplying throughout by y,
3y² + 20 = 17y
3y² - 17y + 20 = 0
3y² - 12y - 5y + 20 = 0
3y (y - 4) - 5 (y - 4) = 0
(3y - 5) (y - 4) = 0
3y - 5 = 0 or y - 4 = 0
y = 5/3 or y = 4
Let y = 4, then x = 20/4 = 5
Dimension of the new classroom is (x+3) = 8 meters and (y+1) = 5 meters
Hence the dimension of the new classroom is 8 meters and 5 meters.

The coordinates of B' after the translation represented by (x - 4, y - 3) is (1, -2). See other solutions below
The coordinates of B' after the translationB is located at the point (5, 1) in the figure.
If we translate the point by (x - 4, y - 3), the new location of B, denoted by B', can be found by subtracting 4 from the x-coordinate and 3 from the y-coordinate.
Therefore, B' is located at (1, -2).
The isometry transformationThe given information provides us with a set of matching points, which are:
Preimage = (2, 1)
Image = (-1, 2)
These points can be represented by the equation:
(x, y) = (-y, x)
This equation indicates that the points have undergone a (d) clockwise rotation of 270 degrees.
The statements of the dilationHere, the smaller shape is created by scaling down a larger shape, the transformation is a dilation that results in a reduction.
The scale factor for this transformation could be either 1/2 or 1/4.
The glide transformatonGiven the points P = (3, -2) and S = (4, -5), we apply two transformations.
The first transformation (x - 2, y) is defined as shifting the x-coordinate of each point left by 2 units, while keeping the y-coordinate the same.
This results in new points P' = (1, -2) and S' = (2, -5).
The second transformation involves reflecting the new points across the x-axis, which changes the sign of their y-coordinates.
The resulting points are P'' = (1, 2) and S'' = (2, 5).
The new ordered pair of point AIn this context, we are given the coordinates of point A as (-2, -5).
This implies that if we scale down the original coordinates by a factor of 1/2, we get the new coordinates of point A, which become (-1, -2.5).
Therefore, the coordinates of point A' are (-1, -2.5).

The CEO of Super Electronics asked customers to fill out a survey to win a $100 gift certificate. The customers were asked to list the products they purchased that day. 88 bought laptop computers. 52 bought desktop computers. 64 bought printers. What is the probability that the winner of the gift certificate bought a printer from Super Electronics? A.
Answer:
To calculate the probability that the winner of the gift certificate bought a printer from Super Electronics, we need to use the total number of customers who participated in the survey as the denominator and the number of customers who bought printers as the numerator.
The total number of customers who participated in the survey is:
Total Customers = Number of Customers who bought Laptops + Number of Customers who bought Desktops + Number of Customers who bought Printers
Total Customers = 88 + 52 + 64
Total Customers = 204
The number of customers who bought printers is 64.
Therefore, the probability that the winner of the gift certificate bought a printer from Super Electronics is:
P(Bought a Printer) = Number of Customers who bought Printers / Total Customers
P(Bought a Printer) = 64 / 204
P(Bought a Printer) = 0.3137 (rounded to 4 decimal places)
So, the probability that the winner of the gift certificate bought a printer from Super Electronics is 0.3137 or approximately 31.37%.
