Let f(x)=3 x²-4 and g(x)=x-2 . Calculate (f ⁰ g⁻¹)(x) for x=-3 .
If the inverse of f exists, it is represented by f⁻¹ and exists only if f is a bijective function.
If x = -3 then (f ⁰ g⁻¹)(x) is 23.
What is the inverse formula?The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.
An inverse in mathematics is a function that serves to "undo" another function. That is, if f(x) produces y, then putting y into the inverse of f yields x. Invertible functions are those that have an inverse, which is denoted by f1.
Let the two functions be f(x) = 3x² - 4 and g(x) = x - 2
(g⁻¹)(x) = 1 - 2
(g⁻¹)(x) = -1
substitute (g⁻¹)(x) value in (f ⁰ g⁻¹)(x)
(f ⁰ g⁻¹)(x) = (f ⁰ ) (-1)
then f(x) equation is 3 x² - 4 substitute -1 in x
f(-1) = 3(-1)² - 4
f(-1) = -1
Now when x = -3 the (f ⁰ g⁻¹)(x) value is
f(-3) = 3(-3)² - 4
f(-3) = 23
Therefore, the value of (f ⁰ g⁻¹)(x) for x = -3 is 23.

We have,
We can consider the cost price as:
Bought amount = $12.96
We can consider the selling price as:
Selling amount = $48.48
Now,
Markup price can be considered as the profit:
Profit = Sellin price - Cost price
Profit = $48.48 - $12.96
Profit = $35.52

Rebecca has twice as much money as Rachel. If Rebecca gives Rachel $60, then the two of them will have the same amount of money. How much money did Rebecca have originally?
A.
B.
C.
D.
E.
Answer:
Rebecca originally had 240 dollars.
Step-by-step explanation:
Let's set B as Rebecca's money and C as Rachel's.
Rebecca has twice as much money as Rachel
B = 2C
If Rebecca gives Rachel $60, then the two of them will have the same amount of money
B - $60 = C + $60
let's combine the 2 by subtracting the second from the first
B - (B - $60) = 2C - (C + $60)
$60 = C - $60
$120 = C
so Rachel had 120 dollars.
Rebecca had twice as much, so 240 dollars.
If Rebecca gives $60 to Rachel, they have $180 each. Everything checks out.

Angles of Triangles #2: Find the angles below
The missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.
How to find congruent angles?We know that the sum of angles on a straight line is 180 degrees. Thus, we can say that;
∠1 + 118° = 180°
∠1 = 180 - 118
∠1 = 62°
We also know that sum of angles in a triangle is equal to 180°. Thus;
∠1 + ∠2 + 73 = 180
Plugging in the relevant value gives;
62 + ∠2 + 73 = 180
∠2 = 180 - 135
∠2 = 45°
∠2 + ∠3 = 180 - (∠1 + 49)
∠2 + ∠3 = 180 - (62 + 49)
45° + ∠3 = 69
∠3 = 22°
Thus, we conclude that the missing angles of the Triangle are; ∠1 = 62°; ∠2 = 45° and ∠3 = 22°.

The direct variation equation can be used to find other combinations of x and y is y² = 4x³/27
What is direct variation?Direct variation is variation in which one quantity increases as another quantity increases or decreases as anothe rquantity decreases.
How to find equation can be used to find other combinations of x and y?Since we have that the square of y varies directly as the cube of x.
Writing this as a direct variation mathematically, we have
y² ∝ x³
So, the direct variation equation is
⇒ y² = kx³ where k = constant of proportionality
Now, given that when x = 4, y = 2.
Substituting the values of x and y into the equation, we have
y² = kx³
2² = k(3)³
4 = k(27)
k = 4/27
Substituting the value of k into the expression, we have

As per the question statement, we are provided with an expression [tex]\frac{(2x^{2} +3x^{3} -3x^{2} -3x-4x-3)}{(x-2)}[/tex].
We are supposed to simplify the above mentioned expression.
To solve this question, let us simplify the expression, part by part, i.e., first, let us consider the numerator part which is
[2x² + 3x³ - 3x² -3x -4x - 3].
Here, it is clearly visible that the numerator expression consists of terms having same same variable but with different coefficients, such as
[2x², -(3x²)] and [-(3x), -(4x)]. Therefore, we can perform the mentioned operations on the like terms and thus simplify our numerator.
[tex][2x^{2} +(-3x^{2} )]=(2x^{2} -3x^{2} )=-(x^{2})\\[/tex]
And, [tex][(-3x) + (-4x)]=-(3x+4x)=-x(3+4)=-(7x)[/tex].
Hence, [tex](2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=[+3x^{3}+(2x^{2} -3x^{2})-(3x+4x)-3]\\or, (2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=[+3x^{3}+(-x^{2} )-7x-3]\\or, (2x^{2} +3x^{3} -3x^{2} -3x-4x-3)=(+3x^{3}-x^{2}-7x-3)\\[/tex]
And our denominator is (x - 2). Since, [2x² + 3x³ - 3x² -3x -4x - 3] does not equate to Zero for (x = 2), there (x - 2) is not a factor of the numerator, i.e., the numerator cannot be exactly divided by the denominator.
Therefore, the simplest form of our expression [tex]\frac{(2x^{2} +3x^{3} -3x^{2} -3x-4x-3)}{(x-2)}[/tex] is [tex]\frac{3x^{3}-x^{2} -7x-3 }{(x-2)}[/tex].
