The inverse of matrix C is C⁻¹ = [1/9 4/27] [1/27 -5/27].
How to determine inverse of matrix?To find the inverse of matrix C, use the following formula:
C⁻¹ = 1/det(C) × adj(C)
where det(C) = determinant of matrix C and adj(C) = adjugate of matrix C.
To find the determinant of C, use the following formula for a 2x2 matrix:
|a b|
|c d| = ad - bc
So:
det(C) = |5 1|
|12 -3| = (5)(-3) - (1)(12) = -27
Find the adjugate of C, which is the transpose of the matrix of cofactors of C, which is:
|-3|
| 1| = -(-3) = 3
So the upper left cofactor is 3, which is:
|12|
|-3| = -(12) = -12
So the upper right cofactor is -12, which is:
| 1|
|-3| = -(1) = -1
So the lower left cofactor is -1, which is:
|5|
|1| = 5
So the lower right cofactor is 5. Putting the cofactors into a matrix and transposing it gives the adjugate of C:
adj(C) = [ 3 -12]
[-1 5]
Now find the inverse of C:
C⁻¹ = 1/det(C) × adj(C)
= -1/27 × [ 3 -12]
[-1 5]
= [1/9 4/27]
[1/27 -5/27]
So the inverse of matrix C is:
C⁻¹ = [1/9 4/27]
[1/27 -5/27]

The model rocket will have a height of 30 meters at a time of 0.523 seconds and 11.477 seconds, respectively.
How to determine the time associated with the height of a rocket on air
In this problem we have the case of a model rocket being launched, the height of the rocket in time is described by the following quadratic equation:
h(t) = 60 · t - 5 · t²
Where:
h - Height, in meters.t - Time, in seconds.We need to determine the time associated to a given height of 30 meters above the ground. If we know that h(t) = 30, then the times are, respectively:
30 = 60 · t - 5 · t²
6 = 12 · t - t²
t² - 12 · t + 6 = 0

OB.
The solutions are where the graphs of the functions cross the x-axis at z
O C.
The solutions are where the graphs of the functions intersect at
-3.464 and z≈ 3.464
O D.
The solutions are where the graphs of the functions cross the x-axis at z ≈ -4 and ≈ 0.422
The statement that gives the best approximation of the solutions of the equation f(x) = g(x) is:
option A. The solutions are where the graphs of the functions intersect at ≈ 1 and ≈ 3.642.
How did we get the value?To find the solutions of the equation f(x) = g(x), set f(x) = g(x) and then solve for x. Using the given functions, we have:
log(x - 1) = (⅓x² - 4)
Exponentiating both sides:
x - 1 = e^(⅓x²-4)
Solve for x:
x = e^(⅓x²-4) + 1
Therefore, the solutions to the equation f(x) = g(x) are given by the values of x for which the graphs of the functions intersect. To find these points of intersection, plot the graphs of the functions and look for the points where they intersect. In other way round, solving for x numerically:
Based on the given functions, it is clear that g(x) is an upward-facing parabola with its vertex at (0, -4) and x-intercepts at (-2√3, 0) and (2√3, 0). The function f(x) is defined only for x > 1, and its graph is a monotonically increasing curve that approaches infinity as x approaches 1 from the right.
Therefore, there is only one point of intersection between the graphs of f(x) and g(x), which occurs to the right of x = 1. This point of intersection can be found numerically using a calculator or computer software, and it is approximately x ≈ 3.642.
Thus, the statement that gives the best approximation of the solutions of the equation f(x) = g(x) is:
OA. The solutions are where the graphs of the functions intersect at ≈ 1 and ≈ 3.642.

The price of the bed after mark up is $475.00
What is discount?Discount results in the reduction of the selling price of the product, which makes it more attractive for the customer.
The first discount given is 25% , therefore the price of the bed before mark up is

Please Fast only have 10 minutes.
The image coordinates of NMO after the translation is option d: N′(−5, −6), M′(−2, −5), and O′(−3, −7).
What is the image coordinates?To get the image coordinates of the preimage translated -2 units to the left, we simply subtract -2 from the y-coordinates of each vertex:
N' = (Nx - (-2), Ny) = (−5 , 2- (-2)) = (−5, 4)
M' = (Mx - (-2), My) = (−2 , 1 - (-2)) = (−2, 3)
O' = (Ox - (-2), Oy) = (−3 , 3- (-2)) = (−3, 5)
Therefore, based on the above, the image coordinates of NMO after the translation are N′(−5, 4), M′(-2,3 ), O′(−3, 5)
So the reflected vertices are:
The distance from N to the line y = -2 is 4, and -6 - (-2) = -4, so one need to move down 4 units to have a y-coordinate of -6.
The distance from M to the line y = -2 is 3, and -5 - (-2) = -3, so one need to move down 3 units to have a y-coordinate of -5.
The distance from O to the line y = -2 is 5, and -7 - (-2) = -5, so one need to move down 5 units to have a y-coordinate of -7.

Given triangle MNO with vertices:
N = (-5, 2), M = (-2, 1) and O = (-3, 3)It is reflected in line y = - 2.
This reflection doesn't affect the x-coordinates of the vertices and the y-coordinates change.
Since y = - 2 is the line of symmetry, it also represents midpoints of the segments formed by corresponding endpoints of image and preimage.
Using midpoint equation, find the y-coordinates.
Point N'(2 + y)/2 = - 2 ⇒ 2 + y = - 4 ⇒ y = - 6Point M'(1 + y)/2 = - 2 ⇒ 1 + y = - 4 ⇒ y = - 5Point O'(3 + y)/2 = - 2 ⇒ 3 + y = - 4 ⇒ y = - 7So the coordinates of the image are:
N′(−5, −6), M′(−2, −5), O′(−3, −7)This is matching the option D.

Algebra substitution y=-3x+5 2x+y=6
The solution to the system of equations y=-3x+5 and 2x+y=6 is (x,y) = (-1,8).
To solve the system of equations using substitution, we can substitute the expression for y in the second equation with the expression for y in the first equation:
2x + y = 6
2x + (-3x + 5) = 6 (substitute y = -3x + 5)
2x - 3x + 5 = 6
-x + 5 = 6
-x = 1
x = -1
Now that we have found the value of x, we can substitute it back into either of the original equations to find the value of y:
y = -3x + 5
y = -3(-1) + 5
y = 8
We can check our solution by verifying that it satisfies both equations:
y = -3x + 5 => 8 = -3(-1) + 5 => 8 = 8 (true)
2x + y = 6 => 2(-1) + 8 = 6 => 6 = 6 (true)

In order to obtain the decimal equivalent (base 10) of a Mayan numeral, it is imperative to comprehend the positional significance of each constituent symbol.
The numerical system employed here assigns a weight to each digit that corresponds to a certain power of 20. Specifically, the weight associated with the least significant digit is 20 raised to the exponent of 0, while the weight of the digit to its immediate left is 20 raised to the exponent of 1, and so forth.
The Mayan number given, : :|| :||, can be broken down as follows:
The leftmost position has no symbol, which represents a value of 0.
The second position from the left has two shell-like symbols (:), which represent a value of 2x20¹ = 40.

Based on a survey of 1250 employees at a software company, the average number of hours spent in meetings per week is 4.3 with a margin of error of 1.1.
What is the range of values for the actual mean numbers of hours spent in meetings in a week? Enter your answer by filling in the blanks to correctly complete the statement.
The actual mean number of hours spent in meetings in a week is between______and______hours
Answer:
Step-by-step explanation:
The margin of error represents the range of values within which the true population mean is likely to fall with a certain level of confidence. To calculate the range of values for the actual mean number of hours spent in meetings in a week, we can use the formula:
(actual mean) = (sample mean) ± (margin of error)
Substituting the given values, we get:
(actual mean) = 4.3 ± 1.1
To find the range of values, we need to compute the upper and lower bounds of this interval:
Lower bound = 4.3 - 1.1 = 3.2 hours
Upper bound = 4.3 + 1.1 = 5.4 hours
Therefore, the actual mean number of hours spent in meetings in a week is between 3.2 and 5.4 hours.

The likelihood that he or she has a pet given that a student does not have a sibling is 60%. Therefore, the correct option is option D.
Let A denote the event that a student does not have a sibling.
Let B denote the event that a student has a pet.
Then A∩B will denote the event that the student does not have a sibling but he has a pet.
Let P denote the probability of an event in this question.
Then, we have to find the conditional probability of event B which means the likelihood of event B occurring based on the occurrence of event A.

[tex]P(B|A) = \frac{0.15}{0.25}[/tex]
[tex]P(B|A) = \frac{3}{5}[/tex]
[tex]P(B|A) = 0.6[/tex]
which in percentage is:
0.6 * 100 = 60 %
Therefore, the likelihood that he or she has a pet too is 60% and the correct option is option D.

A pole that is 3m tall cast a shadow that is 1.15m long at the same time a nearby building cast a shadow that is 40.75m long. How tall is the building
Answer:
The heights and shadows of the objects are legs of similar right triangles. We can use these similar triangles to set up a proportion to solve for the height of the building.
2.9 / 1.26 = x / 47.25
x = 108.75 m
