What is the length of the hypotenuse of the triangle 8cm 15cm?
The length of the hypotenuse is 17 cm.
Pythagoras' Theorem is the way in which you can find the missing length of a right-angled triangle.
The triangle has three sides, the hypotenuse (which is always the longest), the Opposite (which doesn't touch the hypotenuse), and the adjacent (which is between the opposite and the hypotenuse).
Pythagoras is in the form of;
a²+b²=c²
However, it can also be written in the form of c²=a²+b²
In order to find the hypotenuse, you will have the length of two sides, for example, these could be 3 and 4.
As 'C' is always the hypotenuse, you have to work out the two other lengths, and you do this by squaring the numbers.
3²=9 and 4²=16.
As you're looking for C, you've got to add these together
9+16=25
As a²+b²=c², this means that the answer for C is the square root of 25.
√25= 5
We are given that a = 8 cm and b = 15 cm.
Using Pythagoras' theorem,
c² = a² + b²
Substitute the values,
⇒ c² = 8² + 15²
⇒ c² = 64 + 225
⇒ c² =289
∴ c = 17
Thus, the length of the hypotenuse is 17 cm.

Is quadratic form also factored form?
No, the quadratic form is not the same as the factored form of a quadratic equation.
A quadratic function can usually be represented by many equivalent expressions. For example, a quadratic function might be defined by f(x) = x² + 3x + 2. The quadratic expression f(x) = x² + 3x + 2 is called the standard form, the sum of a multiple x² of and a linear expression (3x + 2 in this case).
In general, the standard form is ax² bx + c
We refer to 'a' as the coefficient of the squared term 'x²', 'b' as the coefficient of the linear term 'x', and 'c' as the constant term.
The function 'f' can also be defined by the equivalent expression (x +2)(x + 1). When the quadratic expression is a multiplication of two factors where each one is a linear expression, this is called the factored form.

-6x <= 3.5 + 1.5x
-6x <= 5
-6x/6 <= 5/6

Among these standards is a standard that defines the maximum slope a wheelchair-accessible ramp may built to. According to the ADA, no wheelchair ramp can rise faster than one unit vertically for every twelve horizontal units.
What is the shortest length of ramp (as measured from the start of the ramp, at the base, to the end of the ramp, at the top) that you can build to reach a ledge .83 meters from the ground?
Shortest length of ramp that can be built to reach a ledge .83 meters from the ground is 8.333 meters, according to the ADA standards.
What is Shortest length?
Shortest length is the shortest distance measured from one end to the other.
According to the ADA standard, the maximum slope for a wheelchair-accessible ramp is one unit vertically for every twelve horizontal units. To find the length of the ramp needed to reach a height of .83 meters, we can use the formula:
rise / slope = run
Where:
rise = the vertical distance to be covered (in this case, .83 meters)
slope = the maximum allowed slope (1:12, or 1/12)
So we can plug in the values we know:
.83 meters / (1/12) = run
To find the length of the ramp, we need to multiply the run by the slope:
run * slope = ramp length
Therefore, the length of the ramp is:
run * (1/12) = (run/12) meters = (10/12) = 8.333 meters.
So, the shortest length of ramp that can be built to reach a ledge .83 meters from the ground is 8.333 meters, according to the ADA standards.

The above values are obtained using substitution.
What is substitution?When in place of a variable, we substitute a value in the function, it is known as substitution.
a. We are given f(x)= 3x-9
So, for finding f(-2), we need to put x=-2
Thus, we get,
f(-2)= 3(-2)-9
f(-2)= -6-9
f(-2)= -15
b. We are given g(x)= x^2
So, for finding g(2), we need to put x=2
Thus, we get,
g(2)= 2^2
g(2)=4
c. Now, we are given that f(x)=0.
In order to find the value of x, we need to put f(x)=0
Thus, we get,
