Answer:
The simplified expression is: [tex]\frac{2m-5}{m-3}[/tex]The simplified expression is undefined for m=3Explanation:
The given expression is:
[tex]\frac{2m^2+m-15}{m^2-9}[/tex]
The numerator can be siplified by using factorization and denominator will be simplified using the formula
[tex]a^2-b^2 = (a+b)(a-b)[/tex]
So,
[tex]= \frac{2m^2+6m-5m-15}{(m)^2-(3)^2}\\=\frac{2m(m+3)-5(m+3)}{(m-3)(m+3)}\\=\frac{(2m-5)(m+3)}{(m-3)(m+3)}\\=\frac{2m-5}{m-3}[/tex]
A fraction is undefined when the denominator is zero. In order to find the value of m on which the simplified fraction will be undefined we will put denominator equal to zero.
So,
[tex]m-3 = 0 => m = 3[/tex]
Hence,
The simplified expression is: [tex]\frac{2m-5}{m-3}[/tex]The simplified expression is undefined for m=3Which types of watermarks are discussed in the paragraph below?

Which loop prints the numbers 1, 2...100?
c = 1
while (c <= 100):
c = c + 1
print (c)
c = 1
while (c < 100):
c = c + 1
print (c)
c = 1
while (c <= 100):
print (c)
c = c + 1
c = 1
while (c < 101):
c = c + 1
print (c)
Answer:
while (c <= 100):
print (c)
c = c + 1
Explanation:
We can cancel out the while loops with ' < ' because then it won't print when C is 100.
while (c <= 100):
print (c)
c = c + 1
Is probably right because unlike the other while loop with ' <= ' it has a print statement before the C = C + 1 which means look at this:
C = 1
print(c)
C = C + 1
So when it's run 1 is printed
But when doing the other while loop:
c = 1
while (c <= 100):
print (c)
c = c + 1
C = 1
c = c + 1
print(c)
It prints 2 because it added 1 to C first before actually printing it.
The loop that prints the numbers 1, 2...100 is
c = 1
while (c <= 100):
print (c)
c = c + 1
We are to find the loop that prints the numbers 1 , 2 …100.
Therefore, the loop that print 1 to 100 can be represented as follows:
c = 1
while (c <= 100):
print (c)
c = c + 1
c is a variable initialize with zero.
The while loop is used to check if c is less than or equals to 100.
If c is less than or equal to 100 we print the value of c .
Then we add 1 to c and go back to the loop again.

La sección de lectores de un diario de la ciudad impone como única restricción para la publicación de las cartas, que el texto debe ser de 1500 caracteres. ¿Cuál será el tamaño en KB de un archivo txt que contenga ese texto?
Answer:
El tamaño de un archivo .txt que contenga esa cantidad de texto será de 1.46 KB.
Explanation:
Se entiende que todo caracter informático posee un tamaño de 1 byte, con lo cual en total el texto no puede superar los 1,500 bytes de tamaño.
Ahora bien, un kilobyte es una unidad de medida informática superior, que se compone de 1,024. Por lo tanto, dado que 1,500 - 1,024 es igual a 474, el tamaño del archivo será de 1 KB y 474 bytes. Así, para calcular el tamaño total del archivo en KB, se debe realizar el siguiente cálculo:
1,024 = 1
474 = X
((474 x 1) / 1,024) = X
0.46 = X
Así, el tamaño de un archivo .txt que contenga esa cantidad de texto será de 1.46 KB.

What is the average rate of change of h(x)=2^{x+1}h(x)=2 x+1 h, (, x, ), equals, 2, start superscript, x, plus, 1, end superscript over the interval [2,4][2,4]open bracket, 2, comma, 4, close bracket?
Answer:
Average Rate = 12
Explanation:
Given
h(x) = 2^(x + 1)
Interval = [2,4]
Required
Determine the average rate of change
The average rate of change of h(x) is calculated using.
Average Rate = (h(b) - h(a))/(b - a)
Where
[a,b] = [2,4]
Meaning a = 2 and b = 4
So, the formula becomes:
Average Rate = (h(4) - h(2))/(4 - 2)
Average Rate = (h(4) - h(2))/2
Average Rate = ½(h(4) - h(2))
Calculating h(4)
h(4) = 2^(4+1)
h(4) = 2⁵
h(4) = 32
Calculating h(2)
h(2) = 2^(2+1)
h(2) = 2³
h(2) = 8
So, we have:
Average Rate = ½(h(4) - h(2))
Average Rate = ½(32 - 8)
Average Rate = ½ * 24
Average Rate = 12
Hence, the average rate of change is 12
