How many two digit numbers have an odd number of factors?
There will be 6 two-digit numbers having an odd number of factors.
According to the question,
We have the following information:
There are two-digit numbers.
It means that the list of numbers is from 10 to 99.
Now, we have to find the numbers with the odd number of factors.
We know that odd numbers are the numbers which are not divisible by 2. For example, 1, 3, 5, etc. are odd numbers.
Note that 1 is also included as a factor.
Now, the numbers with odd number of factors will be the perfect squares as 1 will be added to them and the numbers will become odd.
So, the perfect two-digit square numbers are 16, 25, 36, 49, 64 and 81.
Now, we can prove that these numbers satisfy the given conditions by taking factor of any one number.
Let's take 25. The factors of 25 are 1, 5, and 5. So, in total there are 3 factors.
Hence, there are 6 two-digit numbers having an odd number of factors.

The scale from a garden to drawing is 8 ft to 1 cm the scale from the same garden to another drawing is 2 ft to 1 cm what are the lengtgs of the base snd height of the garden in the other scale drawing?
The lengths of the base and height of the garden in the other scale drawing is 9.6 cm and 14.4 cm
How to calculate the value?The scale from a garden to the illustration is stated as 8 feet to 1 centimeter in the question. The drawing's base and height are each 2.4 cm long and 3.6 cm tall, respectively.
As a result, the lengths of the garden's base and height are, respectively, 2.4*8 ft (19.2 ft) and 3.6*8 ft (28.8 ft).
We now know that the scale is 2 feet to 1 centimeter between the same garden and another drawing.
Thus, the lengths of the base and the height of the other drawing are 19.2/2 cm. = 9.6 cm. and 28.8/2 cm. = 14.4 cm. respectively.

Point M is the midpoint of PQ. The coordinates of P and M are given below.
M(5,-2) and P(11, - 10)
Based on this information, what are the coordinates of ?
Show all work and provide any necessary descriptions.
Answer:
Q (- 1, 6 )
Step-by-step explanation:
use the midpoint formula to find the coordinates of M then equate the x and y coordinates with the actual coordinates of M
P (11, - 10) and let Q = (x, y ) , then
[tex]\frac{11+x}{2}[/tex] = 5 ( multiply both sides by 2 )
11 + x = 10 ( subtract 11 from both sides )
x = - 1
and
[tex]\frac{-10+y}{2}[/tex] = - 2 ( multiply both sides by 2 )
- 10 + y = - 4 ( add 10 to both sides )
y = 6
coordinates of Q = (- 1, 6 )

Composition Functions
Composition functions are functions that combine to make a new function. We use the notation ◦ to denote a composition.
f ◦ g is the composition function that has f composed with g. Be aware though, f ◦ g is not
the same as g ◦ f. (This means that composition is not commutative).
f ◦ g ◦ h is the composition that composes f with g with h.
Since when we combine functions in composition to make a new function, sometimes we
define a function to be the composition of two smaller function. For instance,
h = f ◦ g (1)
h is the function that is made from f composed with g.
For regular functions such as, say:
f(x) = 3x
2 + 2x + 1 (2)
What do we end up doing with this function? All we do is plug in various values of x into
the function because that’s what the function accepts as inputs. So we would have different
outputs for each input:
f(−2) = 3(−2)2 + 2(−2) + 1 = 12 − 4 + 1 = 9 (3)
f(0) = 3(0)2 + 2(0) + 1 = 1 (4)
f(2) = 3(2)2 + 2(2) + 1 = 12 + 4 + 1 = 17 (5)
When composing functions we do the same thing but instead of plugging in numbers we are
plugging in whole functions. For example let’s look at the following problems below:
Examples
• Find (f ◦ g)(x) for f and g below.
f(x) = 3x + 4 (6)
g(x) = x
2 +
1
x
(7)
When composing functions we always read from right to left. So, first, we will plug x
into g (which is already done) and then g into f. What this means, is that wherever we
see an x in f we will plug in g. That is, g acts as our new variable and we have f(g(x)).

What is an arithmetic sequence ?A group of integers that are arranged in a particular order and share a difference between each term is known as an arithmetic sequence. For instance, the common difference between the numbers 3, 9, 15, 21, and 27 in mathematics is 6. The term "arithmetic progression" can refer to an arithmetic sequence..

Consider P(x) = x^3+3x^2-4, and c=-2. Show the given value of c is a zero of P(x) (this could be done through synthetic division), find all zeros of P(x), and write P(x) in factored form.
Zeros:
Factored form: P(x)=
Answers:
Zeros: -2 and 1
Factored form: P(x) = (x+2)(x+2)(x-1)
====================================================
Explanation:
One way to show that c = -2 is a zero or root of P(x) is to plug it in as the x value and simplify. If we get P(x) = 0, then that input is a root.
P(x) = x^3+3x^2-4
P(-2) = (-2)^3+3(-2)^2-4
P(-2) = -8+3(4)-4
P(-2) = -8+12-4
P(-2) = 4-4
P(-2) = 0
In short, the input x = -2 leads to the output P(x) = 0.
This confirms -2 is a root of P(x). By extension, this tells us that (x+2) is a factor of P(x).
We can determine the other factor using synthetic division as shown in figure 1. See the image below.
The synthetic division table shows us getting a remainder of 0, as highlighted in yellow.
The other stuff in pink represents the coefficients of the quotient.
We have the coefficients 1, 1, -2 which forms 1x^2+1x-2 and that simplifies to x^2+x-2
This further factors to (x-1)(x+2) because we're looking for two numbers that a) multiply to -2 and b) add to 1. Use the FOIL rule to expand (x-1)(x+2) and you should get x^2+x-2 again. This helps confirm the factorization was done correctly.
---------------------
In short, we found that P(x) = (x+2)(x^2+x-2) and it fully factors to P(x) = (x+2)(x+2)(x-1)
Each factor leads to a root.
x+2 = 0 leads to the root x = -2
x-1 = 0 leads to the root x = 1
Visually, each root is an x intercept where the curve either crosses the x axis or touches it before bouncing away. See figure 2 below.

Using the properties of ratio and proportion we can find the value as [tex]\frac{x+1}{x-1}[/tex] .
A theorem built on the idea of proportions enables a computation procedure that is speedier and requires fewer expansions.
When working with rational functions or fractional equations, it is helpful. Use the componendo and dividendo rule to study ratios and proportions. If the ratio of any two provided numbers is the same as the ratio of the other two numbers, then the ratios of the sum of the denominator and numerator to the difference of the denominator and numerator of the two rational numbers are comparable in nature.The given ratio is of the form x = a /b
This can be written in the form of
[tex]\frac{x}{1} = \frac{a}{b}[/tex]
Now we have to find the value of [tex]\frac{a+b}{a-b}[/tex].
Using the componendo and dividendo rule we get:
Adding the denominator to the numerator to get the new numerator and subtracting the denominator from the numerator to get the new denominator.
Mathematically:
[tex]\frac{a+b}{a-b} = \frac{x+1}{x-1}[/tex]
Therefore this is the required result.
