Answer:
[tex]g(x)=-x^2+8x-11\\\\f(x)=x^2-8x+21[/tex]
Step-by-step explanation:
Generally when you're given the vertex of a quadratic, you can express it in vertex form: [tex]f(x)=a(x-h)^2+k[/tex], where (h, k) is the vertex, and "a" is some constant value that determines the stretch/compression and the direction (up or down)
So we know that: (h, k) = (4, 5), meaning we can plug those values into the equation: [tex]f(x)=a(x-4)^2+5[/tex]
we can change the function by changing the value of the constant "a".
we can use two arbitrary values, but in this example I'll use -1 and 1.
this gives us the following functions: [tex]f(x)=(x-4)^2+5\\g(x)=-(x-4)^2+5[/tex]
these two functions are actually very similar, the only different is they're reflected across the x-axis (and some vertical shift) since the y-value is being negated, or at least part of it.
In your question it states (of any form), so I'm assuming we can leave it in vertex form, but just in case I'll expand them further into standard form
[tex]f(x)=(x-4)^2+5\\\\f(x)=(x-4)(x-4)+5\\\\f(x)=x(x-4)-4(x-4)+5\\\\f(x)=x^2-4x-4x+16+5\\\\f(x)=x^2-8x+21[/tex]
We can also expand the other function similarly.
[tex]g(x)=-(x-4)^2+5\\\\g(x)=-[(x-4)(x-4)]+5\\\\g(x)=-[x(x-4)-4(x-4)]+5\\\\g(x)=-[x^2-4x-4x+16]+5\\\\g(x)=-[x^2-8x+16]+5\\\\g(x)=-x^2+8x-16+5\\\\g(x)=-x^2+8x-11[/tex]

To describe a specific geometric sequence, Jamie wrote the recursive formula: (Formula in picture)
Write the first five terms of this sequence.
If Jamie wrote the recursive formula [aₙ = {(aₙ₋₁) * 4}, where (a₁ = 2)] to describe a specific geometric sequence, then the first five terms of this sequence are [2, 8, 32, 125 and 512]
As per the question statement, Jamie wrote the recursive formula
[aₙ = {(aₙ₋₁) * 4}, where (a₁ = 2)] to describe a specific geometric sequence.
We are required to determine the first five terms of this sequence.
To solve this question, first we have to determine the values of "n" which goes as (n = 1, 2, 3, 4, 5, 6...)
Now, for (n = 1), (an = a₁ = 2), given in the question statement itself,
And using the question mentioned formula, for (n = 2),
[a₂ = {(a₍₂₋₁₎ * 4}]
Or, [a₂ = (a₁ * 4)]
Or, [a₂ = (2 * 4)]
Or, (a₂ = 8).
Similarly, for (n = 3), [a₃ = {(a₍₃₋₁₎ * 4}]
Or, [a₃ = (a₂ * 4)]
Or, [a₃ = (8 * 4)]
Or, (a₃ = 32).
For (n = 4), [a₄ = {(a₍₄₋₁₎ * 4}]
Or, [a₄ = (a₃ * 4)]
Or, [a₄ = (32 * 4)]
Or, (a₄ = 128).
For (n = 5), [a₅ = {(a₍₅₋₁₎ * 4}]
Or, [a₅ = (a₄ * 4)]
Or, [a₅ = (128 * 4)]
Or, (a₅ = 512)
Hence, the first five terms of this sequence are [2, 8, 32, 125 and 512].

Compute the probability of randomly drawing 10 cards from a deck and getting exactly 5 spades.
Enter the exact answer.
The probability of randomly drawing 10 cards from a deck and getting exactly 5 spades is 0.0468
Formula Required:
Given a set of n items, a group of k items can be chosen in any of the 'n' ways, where 'k' is the number of possibilities. The order in which the choices are made is not significant.
A typical deck of cards contains 52 cards in total. Therefore, there exist (52, 10) scenarios in which 10 cards could be chosen (without replacement) that are exhaustive, mutually exclusive, and equally likely.
Again, there are 13 spades in the entire deck of 52 cards. The remaining (10 - 5) = 5 cards can be drawn from the remaining (52 - 13) = 39 cards in the deck in (39, 5) ways, and 5 spades can be drawn from the 13 spades in (13, 5) ways.
As a result, there are (13, 5) * advantageous scenarios for choosing exactly 5 spades (39, 5)
Consequently, the necessary probability:
= Favorable number of cases for the event / Total number of all possible cases.
= (13 , 5) * (39 , 5) / (52 , 10)
(n, k) = n! / k! (n-k)!
= 0.0468
Therefore, the probability of 5 spades will be 0.0468

Evaluate XYZ squared if x = -2, y = 7, and z= -4.
The required value of XYZ squared would be 3136 which is determined by substituting x = -2, y = 7, and z = -4.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have to evaluate xyz squared if x = -2, y = 7, and z = -4.
⇒ (xyz)²
Substitute the values of x = -2, y = 7, and z = -4 in the above expression
⇒ [(-2) × (7) × (-4)]²
Apply the multiplication operation and we get

Describe the transformations to the basic function. Then, write the equation of the function.
The given function is a graph transformation of the absolute value function.
What are Function Transformations?A function transformation "moves," "resizes," or "reflects" the parent function's graph. Function transformations are classified into three types: Translation, Dilation, and Reflection. Only dilation alters the size of the original shape; the other two transformations change the shape's position but not its size.
Step 1: Parent function y = f₁(x) = |x|
Step 2: f₁(x) is reflected (Reflection) about x-axis to form f₂(x) = -f₁(x) = -|x|
Step 3: f₂(x) is moved to left by 5 units(Horizontal translation) to form f₃(x) = f₂(x + 5) = -|x + 5|
Step 4: f₃(x) is moved up 1 unit (Vertical translation) to form f₄(x) = f₃(x) + 1 = -|x + 5| + 1

What is an angle?Two rays, referred to as the angle's sides and vertex, come together to form an angle. Angles created by two rays are located in the plane where the rays are located.
Dihedral angles are formed when two planes intersect. The angle formed by the rays lying perpendicular to the two intersecting curves at their point of intersection can also be used to define an angle between two intersecting curves.
Angle is a term used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius. In the case of a geometric angle, the arc is centred at the vertex and is bound by the sides.
We know that vertical angles of intersection are equal, so here
⇒ (8w+8) = (9w-5)
⇒ 8w+8 = 9w-5
⇒ 9w - 8w = 8 + 5
⇒ w = 13

$m\angle U=2x\degree$ , and $m\angle V=2\left(m\angle U\right)$ . Find the value of $x$ that makes $\angle U$ and $\angle V$ complementary angles
The value of x that makes ∠U and ∠V a complement of each other is; x = 9
How to find Complementary Angles?
There are different equal angle theorems in math's such as complementary angles, supplementary angles, linear pairs e.t.c
Now, complementary angles are defined as angles that sum up to 90 degrees.
We are given that;
m∠U = 2x°
m∠V = 4m∠U = 4(2x)°
We want to find the value of x that makes ∠U and ∠V a complement of each other.
This means that by the definition of complementary angles, they will sum up to 90 degrees. Thus;
2x + 4(2x) = 90
2x + 8x = 90
10x = 90
x = 90/10
x = 9

Which 2 of the following are correct equations of the line passing through (2, -3) with a slope of five?
y+3 = 5 (x-2)
y= 5x -3
y= 5x + 13
y-3= 5 (x+2)
y= 5x -13
Answer:
The two equations that passes through (2, -3) and has a slope of five are:
y + 3 = 5(x - 2) and y = 5x - 13
Step-by-step explanation:
For the first equation, you get y equal to itself. To do that, you need to simplify the right side of the equation. For 5(x - 2), you will distribute the 5 to the x and -2, equalling to 5x - 10. Next, we subtract 3 from both sides to cancel out the 3 on the left side. The equation is now y = 5x - 13. The -13 is the y intercept so we start at the point (0, -13). Since the slope goes up by 5 for every one point it moves to the right, it will eventually reach the point (2, -3). In other words, you add 1 to the x value and 5 to the y value. The points will look like this: it starts at (0, -13) and goes to (1, -8) and goes to (2, -3). The second equation is equivalent to the first equation. Hopefully this helps you out!

According to the triangle inequality theorem, the measure for the third side can be GE = 6 units, because: A. 3 + 5 > 6, 5 + 6 > 3, and 6 + 3 > 5.
What is the Triangle Inequality Theorem?The triangle inequality theorem states that the set of side measurements that will form a triangle will be the set of side lengths whereby the sum of any two sides will be greater than the third side of the triangle.
For example, if a, b, and c are the side lengths of a triangle, then:
a + b > ca + c > bb + c > aThus, we have the given lengths:
FE = 3 units
FG = 5 units
