Final answer:

The range of the given function is {3, 5, 7}.

Explanation:

The range of a function refers to the set of all possible output values (y-values) it can produce. Given the function represented by the set of ordered pairs {(-4,3), (-1,3), (0,3), (1,5), (3,7)}, to determine its range, we look at the second elements in each ordered pair since they correspond to the y-values produced by the function.

The y-values in the given set are 3, 3, 3, 5, and 7. Even though the value 3 is repeated, it is only counted once in the range. Thus, the range of this function is the set {3, 5, 7}.

Remember, the range includes all unique y-values that the function outputs. This set contains the different y-values that the function produces according to the given ordered pairs, which means these are the possible values that we can get as outputs from this function.

Realized income refers to the amount of income you expect to have, not yet received, including anticipated earnings and future investments.

Realized income represents the income an individual or entity expects to receive but has not yet received. It encompasses anticipated earnings, future investments, and any other income sources that have not yet materialized.

This includes income from salaries, investments, rental properties, or any other sources.

Unlike earned income, which refers to income already received, realized income is a forward-looking concept, reflecting the anticipated financial gains.

It plays a crucial role in financial planning and budgeting, guiding individuals and organizations in making decisions about expenditures, savings, and investment strategies based on expected future income streams.

A number system is defined as a system of writing to express numbers.

We need to find the two consecutive positive integers  which have square root of 85 in between.

Firstly we need to know meaning of consecutive numbers.

Numbers which follow each other continuously in the order from smallest to largest are consecutive numbers.

Let us take some perfect square numbers

1,4,16,25,36,49,64,81,100

We know that square root of 81 is 9

square root of 100 is 10

square root of 85 is in between 9 and 10

Hence between 9 and 10  positive integers is the square root of 85 is there.

For the parent function y = f(x), the vertical stretching or compression of the function is a f(x). 

If | a | < 1 (a fraction between 0 and 1), then the graph is compressed vertically by a factor of a units.
If | a | > 1, then the graph is stretched vertically by a factor of a units.

For values of a that are negative, then the vertical compression or vertical stretching of the graph is followed by a reflection across the x-axis.

Yes,  Y = 0.3x^2 is correct!!

Answer-

[tex]\boxed{\boxed{(x+2)^4=x^4+8x^3+24x^2+32x+16}}[/tex]

Solution-

Given expression is [tex](x+2)^4[/tex]

Applying Binomial Theorem

[tex]\left(a+b\right)^n=\sum _{i=0}^n\binom{n}{i}a^{\left(n-i\right)}b^i[/tex]

Here,

a = x, b = 2 and n = 4

The linear function models the scenario is g(x) = 2.5x + 25 if He receives a base pay plus an additional amount per newspaper delivered option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

Pedro works as a newspaper deliverer. He receives a base pay plus an additional amount per newspaper delivered.

x = the number of newspapers Pedro delivers

y =  the earnings he receives in dollars.

From the data given the linear function can be framed as follows:

y = mx + b

Plug x = 5

y = 37.50

37.50 = 5m + b ...(I)

Plug x = 20, and y = 75

75 = 20m + b ...(II)

After solving equation (I) and equation (II):

m = 2.5

b = 25

y = 2.5x + 25

Replace y with g(x)

g(x) = 2.5x + 25

Thus, the linear function models the scenario is g(x) = 2.5x + 25 if He receives a base pay plus an additional amount per newspaper delivered option (C) is correct.

Answer: Every 60th caller would win both.

Step-by-step explanation:

Since we have given that

every 12th caller receives a free concert ticket.

And

every 15th caller receives a limo ride.

We need to find the first caller who would win.

So, for this we would find L.C.M. of 12 and 15.

And we know the least common multiple of 12 and 15 is 60.

Hence , every 60 th caller would win both.

Option C

The area of the doghouse is [tex]66.5\ ft^{2}[/tex]

Step-by-step explanation:

we know that

The area of trapezoid is equal to

[tex]A=\frac{1}{2}(b1+b2)h[/tex]

where

b1,b2 are the parallel bases of trapezoid

h is the height of trapezoid

in this problem we have

[tex]b1=7\ ft[/tex]

[tex]b2=7+5=12\ ft[/tex]

[tex]h=7\ ft[/tex]

substitute

[tex]A=\frac{1}{2}(7+12)7=66.5\ ft^{2}[/tex]

Answer: The answer is (C) 120 sq. units.

Step-by-step explanation: We are given to find the area of a trapezoid with bases of lengths 8 units and 16 units and height of 10 units.

We know that the area of the trapezoid with 'a' and 'b' as lengths of the bases and height 'h' is given by

[tex]A=\dfrac{1}{2}(a+b)h.[/tex]

Here, a = 8 units, B = 16 units and h = 10 units.

Therefore, the area of the given trapezoid will be

[tex]a\\\\=\dfrac{1}{2}(a+b)h\\\\=\dfrac{1}{2}\times(8+16)\times 10\\\\=24\times 5\\\\=120~\textup{sq. units.}[/tex]

Thus, the correct option is (C).

Step-by-step explanation:

Solution: As given, Volume of a rectangular prism is given by the formula V = l w h, where l is the length of the prism, w is the width, and h is the height.

also , h=2x+9

l= x+2

w= 3 x

So, volume of prism= (2 x+9)(x+2)(3 x)= (3 x)(2 x+9)(x+2)→Using associative property

       =3 x[2 x(x+2)+9(x+2)]→Using (x+a)(x+b)= x(x+a)+a(x+b)=x²+(a+b)x+ab

      = 3 x [ 2 x²+ 4 x+ 9 x+18]

      = 3 x[ 2 x² +13 x+18]

 = (3 x)(2 x²) + (3 x)×(13 x) + (3 x)×(18)→ Using distributive property

= 6 x³+ 39 x² + 54 x → [ use [tex]x^{m} \times x^{n}= x^{m+n}[/tex]

Final answer:

The function f(x) =[tex]x^4 + 4x^2[/tex]  is factored using the difference of squares method to achieve its linear factorization. The final factorization over complex numbers is f(x) = x * x * (x + 2i) * (x - 2i).

Explanation:

To write a linear factorization of the function f(x) = [tex]x^4 + 4x^2[/tex]  to find the factors of the polynomial that are linear, meaning each factor will be of the form (x - c) where c is a constant.

First, notice that the given polynomial is a quadratic in form, where [tex]x^2[/tex] is our variable. This gives us [tex]f(x) = (x^2)2 + 4(x^2)[/tex]which resembles the sum of squares [tex]a^2 + 2ab + b2 = (a + b)^2.[/tex] However, we only have [tex]a^2 + 2ab[/tex], with b being 2, and a being  [tex]x^2[/tex].

To create a perfect square, we can write it as a difference of squares by adding and subtracting 4: [tex]f(x) = (x^2 + 2)^2 - (2)^2[/tex]. This can be factored further using the difference of squares formula, giving us[tex]f(x) = (x^2 + 2 + 2)(x^2 + 2 - 2)[/tex] which simplifies to [tex]f(x) = (x^2 + 4)(x^2).[/tex]

The linear factorization can be found by recognizing that x2 is already a product of linear factors x * x. Since  [tex]x^2[/tex] + 4 cannot be factored over the real numbers, we need to use complex numbers to factor it further.

Using the sum of squares, we get  [tex]x^2[/tex] + 4 = (x + 2i)(x - 2i), resulting in the final linear factorization over the complex numbers: f(x) = x * x * (x + 2i) * (x - 2i).
