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.

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.

The fifth and the twenty fifth terms of the arithmetic sequence are a5 = - 45 and a25 = - 1725

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..

The given expression is [tex]6n - 3n^2[/tex]

The 5th term that is n = 5

thus the given expression will become

[tex]6n-3n^2[/tex]

which is equal 6×5 - 3 (5)²

= 30 - 3 × 25

= 30 - 75

= - 45

The 25th term is n = 25

Thus the given expression that is [tex]6n-3n^2[/tex]

= 6 × 25 - 3× ( 25) ²

= 150 - 3 × 625

= - 1725

If Mandi has 8 dog biscuits, she has 7 dog bowls and each dog bowl gets the same number of dog biscuits, then the number of dog biscuits in each bowl is 1.14 biscuits

Number of dog biscuits that Mandi has = 8 dog biscuits

Number of dog bowls that Mandi has =  7 dog bowls

Each dog bowl get the same number of dog biscuits.

To find the number of dog biscuits in each bowl we have to do the division

Number of dog biscuits in each bowl = Number of dog biscuits that Mandi has ÷ Number of dog bowls that Mandi has

Substitute the values in the equation

= 8/7

= 1.14 biscuits

Hence, if Mandi has 8 dog biscuits, she has 7 dog bowls and each dog bowl gets the same number of dog biscuits, then the number of dog biscuits in each bowl is 1.14 biscuits

= 10 / 2

= 5 gallons

If each serving is in a 1/2 cup, then the number of students that would be able to get some apple juice is:

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.

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.

The lengths of the base and height of the garden in the other scale drawing is 9.6 cm and 14.4 cm

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.

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)).

The range of the given function f(x) = x² + 2 is found as 33/16.

For the given question.

The function is given as;

f(x) = x² + 2

The range of the function for the domain of 1/4.

From the definition of domain put x = 1/4 in the function, the range will be obtained.

f(1/4) = (1/4)² + 2

f(1/4) = 1/16 + 2

f(1/4) = 33/16

Thus, the range of the given function f(x) = x² + 2 is found as 33/16.
