The domen range of the function y = √(x² - 4) is _____.
Please explain with step i need explanation.
Answers
[tex] {\large\underline{\sf{Solution-}}}[/tex]
Given function is
[tex]\rm \longmapsto\:y = \sqrt{ {x}^{2} - 4} [/tex]
We know
Domain of a function is defined as set of those real values of x for which function is well defined.
So, y is defined when
[tex]\rm \longmapsto\: {x}^{2} - 4 \geqslant 0[/tex]
[tex]\rm \longmapsto\: {x}^{2} - {2}^{2} \geqslant 0[/tex]
[tex]\rm \longmapsto\: (x - 2)(x + 2) \geqslant 0[/tex]
[tex]\rm\implies \:x \leqslant - 2 \: \: or \: \: x \geqslant 2[/tex]
[tex]\rm\implies \:x \: \in \: ( - \infty , \: - 2] \: \cup \: [2, \: \infty )[/tex]
Now, To find the range of function
We know,
Range of a function is defined as set of those real values which is obtained by assigning the values to x.
So,
[tex]\rm \longmapsto\:y = \sqrt{ {x}^{2} - 4} [/tex]
On squaring both sides, we get
[tex]\rm \longmapsto\: {y}^{2} = {x}^{2} - 4[/tex]
[tex]\rm \longmapsto\: {y}^{2} + 4= {x}^{2}[/tex]
[tex]\rm \longmapsto\:x = \sqrt{ {y}^{2} + 4 } [/tex]
Now, x is defined when
[tex]\rm \longmapsto\: {y}^{2} + 4 \geqslant 0 \: which \: is \: always \: true \: \forall \: y \in \: real \: number[/tex]
But,
[tex]\rm \longmapsto\:y \geqslant 0[/tex]
Hence,
[tex]\rm\implies \:Range \: of \: function \: = [0, \: \infty )[/tex]
So, we have
[tex]\rm\implies \:Domain \: of \: function : x \: \in \: ( - \infty , \: - 2] \: \cup \: [2, \: \infty )[/tex]
and
[tex]\rm\implies \:Range \: of \: function \: = [0, \: \infty )[/tex]

Khan academy What is the slope of the line?
Answers
Answer:
Slope: 3/4
Step-by-step explanation:
If you want the equation for the line:
y = (3/4)x - 1
However, this is how you find the slope:
You want to find any two point on the graph, however, it's easier if it touches exactly where two number meet. For example I chose:
(0,-1) and (2,4)
Now just find the change in y, and divide it by the change in x
change in y = 3
change in x = 4
So your slope is 3/4

Are the graphs of the equations parallel, perpendicular, or neither? y = 4x + 1 and y = -4x -
Answers
Answer:
I am not sure if you fully typed the second equation, but both of these that are written down intersect, there for are perpendicular.
If the second equation is incorrect, let me know and I'll be happy to help you :)
Parallel lines have the same slope, while perpendicular lines have negative reciprocal slopes (multiplying their slopes result in a product of - 1). The negative reciprocal of 4 is -1/4, and the negative reciprocal of -4 is 1/4.
Since the slopes of both lines are not the same, and that they are not negative reciprocals, then the correct answer is neither.

• No down payment is required.
• The monthly lease payment is $156.99 for 2 years.
a. Calculate the total cost to own the furniture using the Rent-To-Own option.
b. What the amount of the finance charge on this purchase?
c. What simple interest percentage rate is this finance charge? Recall: = �
Answers
Answer:
a) Cost of rent to own option is = ($156.99/month) ( 2 yrs)( 12 month/yr) = $3767.76
b) The amount of the finance charge is = $3767.76 - $3225.00 = $542.76
c) the simple interest rate can be calculated by this formula
I = Prt, where
I = total interest value = $542.76
P = is the present worth or original cost including taxes = $3225.00
t = time in yrs = 2
r = Yearly interest rate, By rearranging the formula:
r = I /Pt, r = ( $542.76 / $3225.00 . 2) ( 100) = 8.415%

Answer:
[tex] 3\sqrt[3]{3} [/tex]
Step-by-step explanation:
First, notice that 81 is divisible by 3.
81/3 = 27
27 is also divisible by 3.
27/3 = 9
9 = 3 * 3
81 = 3 * 3 * 3 * 3
81 = 3^3 * 3
[tex] \sqrt[3]{81} = \sqrt[3]{3^3 \times 3} = 3\sqrt[3]{3} [/tex]

A man deposited $80,000.00 in a bank at 12% compound interest per annum. How much did the man have in the bank at the second year
Answers
The amount that the man have in his bank at the second year is $100,352.
Using this formula
A=P(1+R÷100)^n
Where:
A=Amount
P=Principal=$80,000
R=Rate=12%
n=Number of years=2 years
Let plug in the formula
A=$80,000(1+12÷100)^2
A=$80,000(1+0.12)^2
A=$80,000(1.12)^2
A=$80,000(1.2544)
A=$100,352
Inconclusion the amount that the man have in his bank at the second year is $100,352.
