A group of products are averaged to determine central tendency using the geometric mean. The geometric mean of 7 and 12 is 2√21.
What is meant by geometric mean?The geometric mean in mathematics is a mean or average that, by using the product of the values of the numbers, shows the center tendency or usual value of a set of numbers.
The geometric mean, sometimes known as the compounded annual growth rate, is a tool used in finance to determine average growth rates.
The Geometric Mean (GM) is the average value or mean that reveals the central tendency of a group of numbers by adding up the values of those numbers.
Formula to calculate Geometric Mean is
x = √(a × b)
Where, a = 7 and b = 12
x = √(7 × 12)
x = √(7 × 4 × 3)
x = 2√21
The value of x = 2√21.
Therefore, the geometric mean between the pair of numbers 7 and 12 is 2√21.

Help on solving this quadratic equation.
The discriminant of the quadratic equation is q · (q + 8) < 0. The solution set of this inequality is (0, - 8).
How to determine the family of constants associated to non-real roots of a quadratic equation
The nature of the roots of quadratic equations of the form a · x² + b · x + c = 0 can be inferred by the understading of its discriminant under the following condition:
b² - 4 · a · c < 0
Where a, b, c are the coefficients of the polynomial.
If we know that a = 2 · q, b = q and c = - 1, then the equation of the discriminant is:
q² - 4 · (2 · q) · (- 1) < 0
q² + 8 · q < 0
And by algebraic handling, we find the set of possible values of q:

WHAT IS THE SLOPE FOR THE LINE?
hi
let take two points :
( 0; -1) and (4 ; 2)
here is a = 0 ; f(a) = -1
b = 4 ; f(b) = 2
Slope is : f(a) -f(b) / a-b
let's apply : -1 - 2 / 0-4 = -3/-4 = 3/4
Slope is 3/4
if you want to check result, you can calculate the coordonate of an other point and see if it match.
here I read that there is a point on the line for -4 ; -4
here I can read that Y axis value for X = 0 is -1
as a line is defined by : mx+p
with m = slope and p value for x = 0
so : p = - 1
with m = 3/4 ; x = -4 and p = -1
I can test my line equation and see if it match the result :
3/4 ( -4) - 1 = -12/4 - 1 = -3 -1 = -4
Result match what I see on the graph, so previous result is correct.
: Slope is 3/4
ps : if line grows, the slope can only be positive. if line decrease, slope is negative, if line is constant, then slope is still and equal 0

Vertical compression by a factor of 1/2.
Vertically Stretching and Compressing
It multiplies a function by a positive constant that yields a position whose graph is vertically stretched or compressed relative to the original function's graph. If the constant is greater than 1, it will stretch vertically. If the constant is between 0 and 1, vertical compression is done and you will get vertical compression.
Vertical compression occurs when you multiply the function by a rational scaling factor. The base of the function graph remains the same even when the graph is compressed vertically. Only initial values are affected.

The midpoint of AB is M (2, -2). If the coordinates of A are (8, 1), what are the coordinates of B?
The co-ordinates of point B is (4, -5).
Elaborate about the mid point formula.Let the endpoints of a line segment be [tex]x_{1}[/tex], [tex]y_{1}[/tex], and [tex]x_{2}[/tex], [tex]y_{2}[/tex]. The midpoint is equal to half of the sum of the two points' x-coordinates and half of the sum of the two points' y-coordinates.
Point at A ([tex]x_{1}[/tex], [tex]y_{1}[/tex]) = (8,1)
Point at B ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) = (x,y)
The mid point AB is M (2,-2)
Using the mid point formula:
( [tex]\frac{x_{1} +x_{2} }{2}[/tex], [tex]\frac{y_{1} +y_{2} }{2}[/tex] ) = ( x,y )
[tex]\frac{8 +x_{2} }{2}[/tex] = 2
8 + [tex]x_{2}[/tex] = 4
[tex]x_{2}[/tex] = - 4
And
[tex]\frac{1 + y_{2} }{2}[/tex] = -2
1 + [tex]y_{2}[/tex] = -4
[tex]y_{2}[/tex] = - 5

Two men are pushing a broken down car, mass 1800 kg, along a horizontal road with a combined horizontal force of 1000n. at one instant the car accelerates at 0.25m/s^". what is the value of frictional force acting on car at instant
When 2 men pushes car with mass 1800 kg and their combined horizontal forces are 1000 N, then frictional force acting on the car is 550 N.
The situation can be depicted in the attached picture. F1 and F2 are the horizontal forces of both men, while Fr is the frictional force. Remember that a frictional force is always the opposite of the direction of velocity.
Apply the 2nd Newton law of motion:
∑F = m.a
Where:
∑F = resultant of forces
m = mass of object
a = acceleration
In this situation, ∑F = F1 + F2 - Fr
The given parameters:
m = 1800 kg
a = 0.25 m/s²
F1 + F2 = 1000 N
Substitute these parameters into the 2nd Newton law:
F1 + F2 - Fr = m.a
1000 - Fr = 1800 . (0.25)
1000 - Fr = 450
Fr = 1000 - 450 = 550 N

scores 8 points per second. How long will it be before Raul takes the lead?
Answer:
21 seconds
Step-by-step explanation:
First let's find out how long it would take for them to have the same score.
160 + 5s = 100 + 8s
160 = 100 + 3s
60 = 3s
20 = s
