It is true that if a and b are matrix functions such that the matrices a(0) and b(0) are the same, then a and b are the same matrix function.
What do you mean by the term matrix?Without further explanation, matrices represent linear maps and enable explicit computations in linear algebra. In mathematics, a matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions arranged in rows and columns to represent a mathematical object or a property of such an object. As a result, a significant portion of linear algebra involves the study of matrices, and the majority of the characteristics and operations of abstract linear algebra may be described in terms of matrices. The composition of linear maps, for instance, is represented by matrix multiplication.

4. Which equation is perpendicular to the line y = 3 and passes through the point (-1,3)
The equation that is perpendicular to the line is x = -1
How to determine the equation that is perpendicular to the line?The line equation is given as
y = 3
The point is also given as:
(x, y) = (-1, 3)
A linear equation is represented as
y = mx + c
Where m represents the slope
This means that y = 3 can be represented as
y = 0x + 3
So, the slope is 0
Since the slope is 0, the equation of the perpendicular line must be
x = xt
Where
(xt, y) = (-1, 3)
By comparison, we have
x = -1
Hence, the equation that is perpendicular to the line is x = -1

Given g(x) = 1/3 (2x-1) 2, what is the value of g(8)?
By evaluating in x = 8 we can see that the value of g(8) is 45.
How to evaluate the function g(x)?
Here we have the function:
g(x) = (1/3)*(2x - 1)^2
We want to get the value of g(8), this means that we need to evaluate the function in x = 8.
To do this, we just need to replace the variable "x" in the equation by the number 8.
We will get:
g(8) = (1/3)*(2*8 - 1)^2 = (1/3)*(15)^2 = 3*15 = 45
g(8) = 45

Answer:
8
Step-by-step explanation:
You times 4 by 4 since it's squared =16
You have to times 2 by 2 by 2 like this=8
2x2=4 4x2=8
then subtract them= 16-8= 8
put it over the line where 4 and 2 were
after you subtract 5 and 3= 2
than times 2 by the squared= 2x2= 4
times the 2 with 4= 8
put the 8 under the line so you can divide it
8 divided by 8 is 1
lastly, add 7 and 1= 8
=8
the answer is eight
four squared is 16 and two cubed is eight so sixteen minus eight is eight then five minus three is two then you would figure out what 2 squared us and its four so two times four is eight so the first part is eight over eight which is one and one plus seven in eight

3
The simple interest rate on the account is 13%
Here Sunil deposited $400 for one and a half years, and the interest he gets is $78. He deposits in at the simple rate of interest.
We know that the simple interest formula is
Simple interest = Principle × time × rate/ 100
It is given that,
simple interest = $78
time = 1 [tex]\frac{1}{2}[/tex] year = 3/2 year
Principle = $400
Let the rate of interest be r
So we have
78 =( 400 × 3/2 × r )/100
r =( 78 × 2×100) / (400 × 3)
r = 39%
Therefore the simple interest rate on the account is 13%.

factor this 4r³ - 3r²-4r +3
Answer:
(4r - 3)(r + 1)(r - 1)
Step-by-step explanation:
In order to factor the polynomial [tex]\sf 4r^3 - 3r^2 - 4r + 3[/tex], we can use various factoring methods.
In this case, we can use grouping.
Let's break down the expression and factor it step by step:
Group the terms in pairs:
(4r^3 - 3r^2) +(-4r + 3)
Factor out the greatest common factor from each group:
[tex]\sf r^2(4r - 3) - 1(4r - 3)[/tex]
Notice that both groups have a common factor of (4r - 3): and keeping remaining in bracket
[tex]\sf (4r -3)(r^2-1)[/tex]
Now, the expression r² - 1 can be factored further using the difference of squares:
(r + 1)(r - 1)
So, the fully factored form of the polynomial 4r³ - 3r² - 4r + 3 is:
(4r - 3)(r + 1)(r - 1)

in recent years, the numbers of cell phones and the numbers of pirates have both increased, so there is a correlation, or association, between those two variables. therefore, pirates cause increases in cell phones
Final answer:
When two variables are correlated or associated, it does not necessarily follow that one of the variables is the root cause of the other. Correlation does not always indicate cause.
What are the three forms of mathematical correlations ?The link between variables is described by correlation. It can be characterized as strong or weak, as well as positively or negatively.
Positive correlation occurs when two variables change in the same direction. There are three fundamental forms of correlation. The two variables fluctuate in opposite directions when there is a negative correlation. No association or meaningful connection exists between the two variables, hence there is no correlation.
The correlation coefficient aids in determining how closely two variables are related in a single figure. Finding the crucial variables that other factors depend on and comprehending economic behavior are both facilitated by correlation analysis.
Explanation:
A correlation test determines whether two variables are related. Nevertheless, just because two variables are traveling together does not necessarily mean they are connected. This is why the phrase "correlation does not indicate causation" is used frequently.
As two factors are connected or related, it does not necessarily imply that one of the variables is the main cause of the other. Correlation not always show cause.
