area is determined by what type of measurement?
Area is calculated using length measurements, specifically measurements of two dimensions of a flat or planar shape, such as length and width. The resulting value represents the amount of space occupied by the shape on a flat surface.
Area is commonly measured in square units such as square metres ([tex]m^{2}[/tex]), square feet ([tex]ft^{2}[/tex]), square inches ([tex]in^{2}[/tex]), and so on.
To calculate the area of a flat shape, multiply its length and width by the appropriate unit of measurement.
Area = Length x Width
Similarly, to find the area of a circular surface, we would use the formula for the area of a circle:
Area = π x (Radius)^2
[tex]Area = \pi . (r)^2[/tex]
where π is the mathematical constant pi, and the radius is half the diameter:
So, area is a measure of the amount of space occupied by a flat or planar shape and is calculated using length measurements.

The graph of f(x)=x² was translated 6 units to the left to create the graph of function g. Write an equation in vertex form to represent function g.
The vertex form of a quadratic function is given by:
f(x) = a(x - h)^2 + k
where (h, k) is the vertex of the parabola.
Since the graph of f(x) = x^2 was translated 6 units to the left to create the graph of g, the vertex of g is at the point (h - 6, k).
The vertex of f(x) = x^2 is at (0, 0), so the vertex of g is at (-6, 0).
Since the vertex is at (-6, 0), the equation of g in vertex form is:
g(x) = a(x + 6)^2 + 0
We can find the value of "a" by using another point on the parabola. For example, if we know that g(-3) = 9, then we can substitute these values into the equation and solve for "a":
9 = a(-3 + 6)^2
9 = 9a
a = 1
So the equation of g in vertex form is:
g(x) = (x + 6)^2
Which equation does the graph of the systems of equations solve?
• -x^2+2x+3=x^2-4x+3
•x^2-2x+3=2x^2-4x+3
•x^2-2x+3=2x^2-4x-3
•-x^2-2x+3=x^2-4x+3
The equation that the graph of the systems of equations solve is:
x^2 - 2x + 3 = 2x^2 - 4x + 3
This is the second equation listed.
let f, g,∈ f(r, r) be the functions defined by f(t) = ert and g(t) = est, where r '= s. prove that f and g are linearly independent in f(r, r).
For the defined function f(t)=e^rt and g(t)=e^st where r is not equal to s it was proved that the f and g are linearly independent function in F(r,r).
For the defined function f and g we have,
f(t)=e^rt
g(t)=e^st
Where r is not equal to s.
To prove f and g are linearly independent function we need,
f( t) ± g(t) = 0
Substitute the value of f(t) and g(t) we get,
⇒ e^rt ± e^st = 0
⇒ e^rt ( 1 ± e^( s - r )t = 0
This implies ,
e^rt = 0 or ( 1 ± e^( s - r )t = 0
But e^rt is always greater than zero for all the values of r and t.
e^rt = 0 is not possible.
If ( 1 ± e^( s - r )t = 0
This is possible if and only if r = s .
Which is against the given condition.

My mom chose low numbers for my solution set and I had got two of them to be false. Which the numbers are 3 and 2. First I did was grab the equation. So
13 = 2x + 5
Then I grabbed 3 and put the 3 in front of the 2 but with parentheses around the 2 , so
13 = 2(3) + 5
Then this part is pretty easy for me, but I did. I only got 6 from 2 x 3 and always remove the parentheses when you multiply. You also want to keep the 5 because it is needed for the answer to see if it's a true equation or false. 13 = 6 + 5. Now you always keep the 13 as well, because you have got nothing to multiply them with, so you will do
13 = 11
6 + 5 = 11 and it isn't equal to 13, so it's a false answer. Now the solution set that includes 2 is also false. For this equation
13 = 2(2) + 5
13 = 2 x2 is 4 so
13 = 4 + 5
Add 5 + 4 and you'll get the false answer:
13 = 9
The solution set for this equation is {4}, since 4 is the only value that makes the equation true.
You have done a great job of explaining how to check if the numbers 3 and 2 are part of the solution set for the equation 13 = 2x + 5. You correctly substituted each number in for x and simplified the equation to see if it was true or false. You found that both numbers resulted in a false equation, so they are not part of the solution set.
One thing to note is that the solution set for an equation is the set of all values that make the equation true. So, in order to find the solution set for this equation, you would need to solve for x. Here is how you would do that:
13 = 2x + 5
Subtract 5 from both sides of the equation:
8 = 2x
Divide both sides of the equation by 2:
4 = x
So, the solution set for this equation is {4}, since 4 is the only value that makes the equation true.

Step-by-step explanation:
10x - 34° = 106° ( A.I.A )
x = 72°
106° + z = 180° ( linear pair axiom )
z = 74°
MARK ME AS BRAINILIST
Answer:
x=14°
z= 74°
Step-by-step explanation:
Here
(10x-34)°= 106°
since the Vertically Opposite Angle are equal.
so solving for it.
First, we can add 34° to both sides of the equation to get:
10x° - 34°+ 34° = 106° + 34°
Simplifying the left side gives:
10x° = 140°
Then we can divide both sides of the equation by 10 to get:
x = 14°
Again
z+106°=180°
since the sum of angle in the linear pair is equal to 180°
solving for it
we can subtract 106° from both sides of the equation to get:
z + 106° - 106° = 180° - 106°
Simplifying the left side gives:
z = 74°
A car going 50 mil/hr accelerates to pass a truck. 5 seconds later the care is going 80mil/ Calculate
the acceleration of the car.
Answer:
Step-by-step explanation:
5 seconds later acceleration of the car is 6m/h^2
We know that the initial velocity of a car is 50 mph.
In the end, the final velocity of a car is 80 mph.
The time difference is 5 seconds.
For the calculation of the acceleration, we have this formula,
α = δv/t
so here, according to our data, velocity and time are,
u = 50 mph
v = 80 mph
t = 5 s
Finally, the acceleration of the car can be calculated by,
α = (80 - 50) / 5
α = 30 / 5
α = 6 m/h^2
From the above calculations, the car's acceleration is 6 m/h^2.

Unit 7 polygons & quadrilaterals homework 1 angle of polygons
The angle of polygons is an important concept in geometry and can be calculated using the formula (n-2) x 180. Quadrilaterals are a specific type of polygon with four sides and four angles, and their interior angles can be found by dividing the sum of the interior angles by the number of sides.
What are the angles of polygons?The angle of polygons is an important concept in geometry. A polygon is a closed shape with three or more sides, and the angles of a polygon are the interior angles formed by the sides. Quadrilaterals are a specific type of polygon with four sides and four angles.
To find the sum of the interior angles of a polygon, you can use the formula (n-2) x 180, where n is the number of sides. For example, a quadrilateral has four sides, so the sum of its interior angles would be (4-2) x 180 = 360 degrees.
Each individual angle of a quadrilateral can be found by dividing the sum of the interior angles by the number of sides. So for a quadrilateral, each angle would be 360/4 = 90 degrees.

One important use of the regression line is to do which of the following? a) To make predictions about the values of y for a given x-value. b) To determine the strength of a linear association between two variables. c) To determine if a distribution is unimodal or multimodal. d) Both A and B are correct.
A regression line is defined as an estimate of the line that describes the actual line, which is unknown. It represents a linear relationship between the two variables, that is the dependent and the independent variable.
In other words, the equation of the regression line is used to estimate the value of the dependent variable from a specified value of the independent variable.
Correlation coefficient is used to determine the strength of linear association between two variables, that is the dependent and the independent variable. (Correlation shows what kind of relation two variables have.)
Regression line's important use is to make predictions about the values of y for a given x-value.
Hence option a is correct.
