at a local school, three teaching positions are available for the 2nd grade. if there are 22 applicants, how many ways can those positions be filled?

Answers

Answer 1

There are 1540 different ways to fill the three 2nd grade teaching positions from the 22 applicants.

To determine the number of ways to fill the three 2nd grade teaching positions from 22 applicants, we can use the concept of combinations. Combinations allow us to calculate the number of different selections without considering the order of the chosen items.

The formula for combinations is C(n, k) = n! / (k! * (n-k)!), where "n" represents the total number of items to choose from (in this case, 22 applicants), "k" is the number of items to be chosen (3 teaching positions), and "!" denotes factorial.

Applying this formula, we have:

C(22, 3) = 22! / (3! * (22-3)!)

C(22, 3) = 22! / (3! * 19!)

C(22, 3) = (22 * 21 * 20 * 19!) / (3! * 19!)

C(22, 3) = (22 * 21 * 20) / (3 * 2 * 1)

C(22, 3) = 1540

So, there are 1540 different ways to fill the three 2nd grade teaching positions from the 22 applicants.

In the point-slope form, y - y1 = m(x - x1):

“(x1, y1)” represents (3, 1) coordinate

What is the circumference of a circle circumcised around a rectangle with sides 7 cm and 24 cm

Answers

The circumference of the circle circumscribed around the rectangle with sides 7 cm and 24 cm is approximately 78.54 cm.

To find the circumference of a circle that is circumscribed around a rectangle, we need to determine the diagonal of the rectangle, which will be equal to the diameter of the circle.

Given:

Length of the rectangle = 24 cm

Width of the rectangle = 7 cm

To find the diagonal of the rectangle, we can use the Pythagorean theorem:

Diagonal^2 = Length^2 + Width^2

Diagonal^2 = 24^2 + 7^2

Diagonal^2 = 576 + 49

Diagonal^2 = 625

Taking the square root of both sides, we get:

Diagonal = √625

Diagonal = 25 cm

Since the diameter of the circle is equal to the diagonal of the rectangle, the diameter of the circle is 25 cm.

The circumference of a circle can be calculated using the formula:

Circumference = π * Diameter

Circumference = π * 25 cm

Using an approximate value of π ≈ 3.14159, we can calculate:

Circumference ≈ 3.14159 * 25 cm

Circumference ≈ 78.54 cm

Therefore, the circumference of the circle circumscribed around the rectangle with sides 7 cm and 24 cm is approximately 78.54 cm.

apply the method of undetermined coefficients to find a particular solution to the following system. x' = x-17y+4cos4t y'=x-y

Answers

The particular solution to the given system is: x_p(t) = (-1/17)cos(4t) + Bsin(4t) and y_p(t) = Ccos(4t) + Bsin(4t). This particular solution satisfies the given system of equations.

To find a particular solution using the method of undetermined coefficients, we assume that the particular solution can be written in the form of:

x_p(t) = A cos(4t) + B sin(4t)
y_p(t) = C cos(4t) + D sin(4t)

Taking the derivatives, we have:

x'_p(t) = -4A sin(4t) + 4B cos(4t)
y'_p(t) = -4C sin(4t) + 4D cos(4t)

Substituting these into the given system of equations:

-4A sin(4t) + 4B cos(4t) = A cos(4t) + B sin(4t) - 17(C cos(4t) + D sin(4t)) + 4cos(4t)
-4C sin(4t) + 4D cos(4t) = A cos(4t) + B sin(4t) - (C cos(4t) + D sin(4t))

Simplifying these equations, we get:

(-17A + 1)cos(4t) + (17B - 17C)sin(4t) = 4cos(4t)
(A - C)cos(4t) + (B - D)sin(4t) = 0

Comparing the coefficients of cos(4t) and sin(4t) on both sides, we can equate them to find the values of A, B, C, and D:

-17A + 1 = 4
17B - 17C = 0
A - C = 0
B - D = 0

Solving these equations, we find:

A = -1/17
B = C
D = B

Therefore, the particular solution to the given system is:

x_p(t) = (-1/17)cos(4t) + Bsin(4t)
y_p(t) = Ccos(4t) + Bsin(4t)

This particular solution satisfies the given system of equations.

Which describes how triangle FGH could be transformed to triangle F prime G prime H prime in two steps?

On a coordinate plane, triangle F G H has points (negative 2, 1), (negative 3, 3), (0, 1). Triangle F prime G prime H prime has points (negative 8, negative 4), (negative 12, negative 12), (0, negative 4).

Answers

Answer:

Translation: Shift the entire triangle 6 units to the left and 5 units down.

Dilation: Enlarge the triangle by a factor of 4.

Step-by-step explanation:

To describe how triangle FGH can be transformed to triangle F'G'H' in two steps, we need to identify the specific transformations applied.

Translation:

The first step involves a translation, where the entire triangle is shifted by a certain amount horizontally and vertically. To determine the translation vector, we subtract the coordinates of corresponding vertices from F'G'H' from those of FGH.

Translation vector = (x-coordinate difference, y-coordinate difference) = ((-8) - (-2), (-4) - 1) = (-6, -5)

So, the translation vector is (-6, -5), indicating that the triangle is shifted 6 units to the left and 5 units down.

Dilation:

The second step involves a dilation, which changes the size of the triangle. To determine the dilation factor, we can compare the lengths of corresponding sides.

The length of side FG is given by the distance formula:

FG = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((-3 - (-2))^2 + (3 - 1)^2) = sqrt(1^2 + 2^2) = sqrt(5)

The length of side F'G' is given by the distance formula as well:

F'G' = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((-12 - (-8))^2 + (-12 - (-4))^2) = sqrt(4^2 + 8^2) = sqrt(80) = 4sqrt(5)

The dilation factor is the ratio of the corresponding side lengths:

Dilation factor = F'G' / FG = (4sqrt(5)) / sqrt(5) = 4

The dilation factor is 4, indicating that the triangle is enlarged by a factor of 4.

Bags of dog food are labeled 1 through 50. What is the probability that the dog will choose a numbered dog bag that is not a multiple of 11

Answers

Probability helps us to know the chances of an event occurring. The probability that the dog will choose a numbered dog bag that is not a multiple of 11 is 8%.

Given that Bags of dog food are labelled 1 through 50.

Now, the bags that are multiples of 11 are 11, 22, 33, and 44, therefore, a total of 4 bags are there.

Now, the probability that the dog will choose a numbered dog bag that is not a multiple of 11 is,

Probability = Number of bags that are not a multiple of 11/Total number of bags

= (50 - 4)/50

= 23/25

= 0.92

Hence, the probability that the dog will choose a numbered dog bag that is not a multiple of 11 is 8%.

For the pair of functions, write the composite function and its derivative in terms of one input variable. k(t) = 4.5+3 – 7t2 + 3t – 4; t(x) = In x

Answers

The composite function k(t(x)) is -2.5 - 7(ln x)^2 + 3(ln x), and its derivative is -14ln x + 3/x.

To find the composite function k(t(x)), we substitute the expression for t(x) into the function k(t) as follows:

k(t(x)) = 4.5 + 3 - 7t(x)^2 + 3t(x) - 4

k(t(x)) = 4.5 + 3 - 7(ln x)^2 + 3(ln x) - 4

Simplifying this expression, we obtain:

k(t(x)) = -2.5 - 7(ln x)^2 + 3(ln x)

To find the derivative of the composite function, we use the chain rule as follows:

k'(t(x)) = k'(t) * t'(x)

where k'(t) is the derivative of the function k(t) with respect to t, and t'(x) is the derivative of the function t(x) with respect to x.

The derivative of k(t) with respect to t is:

k'(t) = -14t + 3

The derivative of t(x) with respect to x is:

t'(x) = 1/x

Substituting these expressions into the chain rule, we obtain:

k'(t(x)) = (-14t(x) + 3) * (1/x)

k'(t(x)) = (-14ln x + 3/x)

Therefore, the composite function k(t(x)) is -2.5 - 7(ln x)^2 + 3(ln x), and its derivative is -14ln x + 3/x.
