Answers

Answer 1

Ok relax this is really easy

Rational numbers are those which can be expressed as a fraction of 2 whole numbers
(2/3 , 1/2 etc)

Irrational numbers are those that CAN NOT be expressed as a fraction of 2 whole numbers
( pi, square root of 2, etc)

*Extra notes to help differentiate*

-An irrational number has endless non-repeating digits to the right of the decimal point.

- Every whole number is a rational number, because any whole number can be written as a fraction. For example, 2 can be written as 2/1

An elevator is at a height of 200 feet. It is descending at a constant rate of 8 feet per second. What is the height, in feet, of the elevator after 13 seconds??

Answers

Answer:

304

Step-by-step explanation:

8 x 13 = 104

+200

304

Answer:

96feet

Step-by-step explanation:

U want to find displacement

Displacement = velocity x time

Velocity = - 8 feet/s ( negative bcuz going down)

Time = 13

Displacement = - 8 x 13

= - 104

Therefore

200 - 104 = 96feet

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The cost difference between the new and refurbished computer is $800.00 - $640.00 = $160.00. This means that you would save $160.00 by buying the refurbished computer instead of the new one.

Let's say you work for "x" hours, then your gross pay will be:

A = 10x dollars

Your FICA deduction will be 7.65% of your gross pay:

0.0765 ( 10x ) = 0.765x dollars

Your federal tax withholding will be 12% of your gross pay:

0.12 ( 10x ) = 1.2x dollars

Your state tax withholding will be 8% of your gross pay:

0.08 ( 10x ) = 0.8x dollars

The total amount of taxes that will be deducted from your paycheck is the sum of these three amounts:

0.765x + 1.2x + 0.8x = 2.765x dollars

So your net pay will be:

10x - 2.765x = 7.235x dollars

On simplifying the equation , we get

Now, we can calculate the number of hours you would need to work to pay for the new computer:

800 = 7.235x

x ≈ 110.5 hours

Hence , the number of hours is x = 111 hours

What is the inverse of the function f(x) = 2x – 10?
O h(x) = 2x-5
Oh(x) = 2x + 5
Oh(x) =
Ix-5
x) = {x+5
Oh(x) =

Answers

If h(x) is the inverse of f(x), then by definition of inverse function, we have

f(h(x)) = x

By definition of f(x), composing f with h gives

f(h(x)) = 2 h(x) - 10

Solve for h(x) :

x = 2 h(x) - 10

2 h(x) = x + 10

h(x) = (x + 10)/2

h(x) = x/2 + 5

So... whichever option most closely resembles this is the correct one. It's hard to tell exactly which one that would be.

Step-by-step explanation:

Given equation

Simplify by subtraction

3x + 11 = 81

Subtract 11 on both sides

3x + 11 - 11 = 81 - 11

3x = 70

Divide 3 on both sides

3x / 3 = 70 / 3
