What is the correct classification of 7x2 + 9x + 4? Select one of the options below as your answer:A. monomial B. binomial C. trinomial

Answers

Answer:

The correct classification is trinomial.    

Step-by-step explanation:

Given the equation

7x^2+9x+4

we have to choose the options.

Monomial is an algebraic expression containing one term, binomial with two terms and trinomial with 3 terms.

Now, the given expression

7x^2+9x+4

consisting of 3 terms therefore called trinomial.

Hence, the correct classification is trinomial.
B. binomial

this expression has two terms (whole numbers and a x-term

Answers

There seems to be a mistake in typing. You probably type the letter "i" as "1", so it is difficult to tell which numbers are complex numbers.

I will however explain what complex numbers look like, which will help you in determining which numbers are complex numbers, and the rest are real numbers.

Step-by-step explanation:

Complex numbers are numbers that include the square root of a negative number.

It is not possible to have a value for an expression with a square root of a negative number, then the letter j or i were introduced to help represent these kinds numbers.

√-1 = i or j (anyone is fine)

Knowing the square root of -1 is i, we can write the square root of any negative number with ease.

√(-6) = √(-1) × √6, right?

= i × √6

= i√6

And so on.

So, basically, the numbers that include the letter 'i', or √(-1) in them are the complex numbers. The rest are real numbers.

1) Find the inverse function of f(x)=1/2x+32)Use composition to verify that they are inverse relations?
3) f^ Domain : Range:
4) f^-1 Domain : Range:

Answers

 y = 1/2x + 3
change x and y

x = 1/2y + 3
now find the value of y and that is inverse function 

x - 3 =1/2 y
y = 2x- 6
 
f-(x) = 2x - 6


for both domain : ( - ∞ , + ∞ )

range f (x) : ( - ∞ , + ∞ )  - { 0 }
range f-(x) :( -∞ , +∞)
To find the inverse function you need to change f(x) (call it y) and x, then solve for y:

y = (1)/(2)x+3 \n x = (1)/(2)y + 3 \n x - 3 = (1)/(2)y \n 2x-6 = y

So now you have f^(-1)(x) = 2x-6.

Composition to prove inverse relation: f \circ f^(-1) (x) = x:

f(f^(-1)(x)) = (1)/(2)(2x-6)+3 = x - 3 + 3 = x \square

Domain and Range of both functions is Real numbers since they are both linear equations.

If you are paid $23.25 per hour, what is your annual salary? (Assume you work 40 hours each week of the year.)

Answers

$23.25 per hour
work 40 hours per week
Find your annual Salary
In a month, there are approximately 4 or 5 weeks  (only refer to regular working days)
Let’s only use 4.
=> 40 x 4
=>160 hours in 1 month
In a years there are 12months
=> 12 x 4
=> 48 weeks in a years (only for regular working days) or let’s round it to 50 weeks per year
Now, let’s multiply 48 weeks by 40 hours and 50 by 40 hours
=> 48 x 40
=> 1920 hours in a year
=> 50 x 40
=> 2000 hours
Now, let’s  find how much is your annual salary
=> 1920 x 23.25 = $44 640
=> 2000 x 23.25 =$46500
=>approximate  or around
