The complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.
What is a polynomial function?A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Rearranging the equation x² - 51 = 14
x²- 14x -51 = 0
x² - 14x + 49 - 49 - 51 = 0
(x - 7)² = 100
x - 7 = √100
x - 7 = ± 10
Taking RHS positive,
x - 7 = 10
x = 17
Taking RHS negative
x - 7 = -10
x = 7 - 10
x = -3
Thus, the complete square of the given equation is (x - 7)² = 100 and the solution to the equation is x = 17 and -3.

The length of a to the nearest 10th of an inch is 13.6 inches.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
In ΔQRS q=9.6 inches r=9.9 inches and S=92.
So, s² = q² + r² - 2qr cos s
s² = 9.6² + 9.9² + 2(9.6)(9.9) cos 92.
s² = 190.71 + 190.08 x (-0.035)
s² = 183.52
s = 13.55
s = 13.6 inches

Divide P. 80.00 people so that the second will have twice as much as the first and the third will have P. 5.00 less than the second. how much the first, second and third person gets?
Answer:
first collects 17, second 34 and third 29
Step-by-step explanation:
Total amount to be shared = 80.00
If first person received x
second received y
Third received z
If the second will have twice as much as the first, then;
y = 2x
x = y/2
If the third will have P. 5.00 less than the second, then
z = y-5
y = z+5
Substitute both equation in original equation
x+y+z = 80
y/2 + y + y-5 = 80
y + 2y + 2y -10 = 160
5y = 160+10
5y = 170
y = 170/5
y = 34
x = y/2
x = 34/2
x = 17
z = y - 5
z = 34-5
z = 29
Hence the first collects 17, second 34 and third 29

Enter the ordered pair for the vertices for 180°,0)(QRST).
Q

S
IR
O Q' = (-1,-3) R' = (-3,3 ) S'= (0,2)T' =(2, -1)
OQ' = (-1,3) R' = (-3,-3) S'=(0, -2)T' =(2, 1)
Q' = (1, -3) R' =(3,3) S' = (0,2)T' = (-2,-1)
Answer:
The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is given as follows;
Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1)
Step-by-step explanation:
The coordinates of he vertices of the triangle QRST are;
Q(1, 3), R(3, -3), S(0, -2), T(-2, 1)
A rotation of a point with coordinates (x, y) 180° about the origin gives;
The coordinate of the point of the preimage before the rotation = (x, y)
The coordinate of the point of the image after the rotation = (-x, -y)
Therefore we have;
The image of point Q(1, 3) after 180° rotation = Q'(-1, -3)
The image of point R(3, -3) after 180° rotation = R'(-3, 3)
The image of point S(0, -2) after 180° rotation = S'(0, 2)
The image of point T(-2, 1) after 180° rotation = T'(2, -1)
The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is therefore, Q'(-1, -3), R'(-3, 3), S'(0, 2), and T'(2, -1);
Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1).
si un costal de azúcar contiene 61.5Kg ¿cuántos paquetes de 0.750Kg se pueden llenar?
Answer:
Cantidad total = 82 Paquetes
Step-by-step explanation:
Dados los siguientes parámetros;
Cantidad de azucar = 61.5kg
Tamaño de cada paquete = 0.75kg
Para encontrar la cantidad total de paquetes;
[tex] Cantidad \; total = \frac {Cantidad}{Tamano \; de \; cada \; paquete} [/tex]
[tex] Cantidad \; total = \frac {61.5}{0.75} [/tex]
Cantidad total = 82 Paquetes.
Por lo tanto, se pueden llenar 82 paquetes de azúcar.

If x + 3 = 13, then the value of 5x – 74 is
Answer:
-24
Step-by-step explanation:
We are given two equations and are asked to solve if one equals a certain amount to the other.
Let's focus on x + 3 = 13, we need to first figure out what is x. Which is very simple, what plus 3 equals 13?
10 of course, therefore x = 10, and we can implement into the other equation.
5x - 74
Since x = 10, we can substitute x with 10 and then multiply.
5(10) - 74
50 - 74
What is 50 - 74?

A function is given:
f(x) = 3x + 12
a. Determine the inverse of this function and name it g(x).
b. Use composite functions to show that these functions are inverses.
c. Evaluate f(g(–2)). Explain: What is the domain?
Answer:
See explanations below
Step-by-step explanation:
Given the function
f(x) = 3x+12
Let y = f(x)
y = 3x+12
Replace y with x
x = 3y+12
Make y the subject
3y = x-12
y = (x-12)/3
Hence the required inverse is!
g(x) = (x-12)/3
b) To show that the functions are inverses, we must show that f(g(x)) = g(f(x))
f(g(x)) = f((x-12)/3)
Replace x in f(x) with x-12/3
f(g(x)) = 3(x-12)/3 +12
f(g(x)) = x-12+12
f(g(x)) = x
Similarly for g(f(x))
g(f(x)) = g(3x+12)
g(f(x)) = (3x+12-12)/3
g(f(x)) = 3x/3
g(f(x)) = x
Since f(g(x)) = g(f(x)) = x, hence they are inverses of each other
c) Given f(g(x)) = x
f(g(–2)) = -2
The domain is the input variable of the function. Hence the domain is -2
