The equation for distance on a cartesian plane coordinate system is based off the pythagorean theorem.
[tex]a^2 + b^2 = c^2[/tex]
a and b being sides of a right triangle, c being the hypotenuse.
When we are solving for distance we are solving for c essentially.
[tex]c[/tex] = [tex]\sqrt{a^2 + b^2}[/tex]
Because a and b are side lengths of the right triangle, we need to find a way to find that in terms of coordinates. So here we might say that a is equal to the horizontal distance between the 2 points or Δx, and we would say that b is the vertical distance between the 2 points Δy.
(solutions)
So essentially distance is:
[tex]d = \sqrt{(x_2 - x_1)^2+ (y_2-y_1)^2 }[/tex]
Now we just use the values given to us, and sub in the x and y values respectively.
(-2,4) [tex]x_1 = -2, y_1 = 4[/tex]
(5,4)[tex]x_2 = 5, y_2 = 4[/tex]
plug these values in:
[tex]d = \sqrt{((5) - (-2))^2+ (4-4)^2 } = \sqrt{(7)^2+ (0)^2 } = \sqrt{7^2 } = 7[/tex]
Therefore the distance is 7 units.
Why every values in maths has an approximation ?
( Example : The value of π,... )
Answer:
Approximating has always been an important process in the experimental sciences and engineering, in part because it is impossible to make perfectly accurate measurements. Approximation also arises because some numbers can never be expressed completely in decimal notation. In these cases approximations are used.

Find the measure of the missing angle in this isosceles triangle.
The measure of the missing angle(a) in the isosceles triangle(two sides and angle equal) is 70 degrees.
What is an Isosceles triangle?
An Isosceles triangle is a triangle that has two of it sides equal to each other and two of it angles equal to each other.
The base angle of an isosceles triangle are equal. Therefore, let's find angle a in the triangle.
55 + 55 + a = 180
Recall the sum of angle in a triangle is 180 degrees.
110 + a = 180
subtract 110 from both sides
110 - 110 + a = 180 - 110
a = 70 degrees

A side of the triangle below has been extended to form an exterior angle of 124°. Find the value of x.
Answer:
56 degrees
Step-by-step explanation:
The angles x and 124 are supplementary angles, which means they add up to 180 degrees.
Thus,
We are left with this equation.
[tex]124 + x = 180[/tex]
Subtracting 124 from both sides, we are left with
[tex]x = 56[/tex]

What is the solution to the equation t minus 15 = 76?
t minus 15 = 76. t minus 15 minus 15 = 76 + 15. t = 91.
t minus 15 = 76. t minus 15 + 15 = 76 + 15. t = 91.
t minus 15 = 76. t minus 15 minus 15 = 76 minus 15. t = 61.
t minus 15 = 76. t minus 15 + 15 = 76 minus 15. t = 61.

Jay is measuring the angles of a triangle. He gets 30 degrees and 100 degrees, what is the measured third angle?
Answer:
50°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180° , that is
3rd + 30° + 100° = 180°
3rd + 130° = 180° ( subtract 130° from both sides )
3rd angle = 50°
Answer:
50 degrees
Step-by-step explanation:
In any triangle, there are 180 degrees. If we add 100 degrees plus 30 degrees to get 130, simply subtract that from 180 the get the measure of the third angle. (180-130= 50) Hope this helps!

Answer:
$25,626.53
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
P = initial balance
r = interest rate (decimal)
n = number of times compounded annually
t = time
First, change 8.5% into a decimal:
8.5% -> -> 0.085
Now lets plug in the values into the equation
Lastly, subtract the total from the initial balance:
Michelle earned $25,626.53 in interest.
