Given:
The vertices of a right triangle are:
To find:
The length of the hypotenuse of the given right triangle.
Solution:
Let the vertices of the right triangle are .
The distance formula is:
Using distance formula, we get
Similarly,
And,
Now, taking sum of squares of two smaller sides, we get
By the definition of the Pythagoras theorem, AC is the hypotenuse of the given triangle.
Therefore, the length of the hypotenuse is 10 units.
Given : A social media website has currently = 1,000 members.
In each month number of members gets triple.
To find: Equation that represents number of members m belongs to site.
Solution: Because we are given, each month the number of members gets triple, that means each month we can multiply by 3 to the number of members of previous month.
For first month, we would multiply 1,000 by 3.
For second month, we would multiply 1,000 by 3 *3.
For second month, we would multiply 1,000 by 3*3*3.
Each month one factor of 3 is being increasing.
We could write those 3's as exponents of 3.
Like
As many months as many 3's are there.
So, the exponent of 3 is represnts the number of months.
Let us take a variable for number of month by n.
So, we could setup an equation for number of members m belongs to site on a particular month n as
This is our final equation.
