Answer:
x = 6
Step-by-step explanation:
- In is right angle. (Given)
- (Given)
- (By geometric mean theorem)
- Value of x cannot be negative.
ok, so x is a number ranging from 40-90 which is 50 meaning that x has 50 different possibilities. But what are the chances that x is 75? well the chances of x being 75 is 1 out of 50.
so that means there is a 2% chance of x being 75

Answer:
The domain is the set of values you put into the function.
The range is the set of values the function outputs.
<u>Example problem</u>:
Find the range of this function: y = 2x + 3, x > 0
The x > 0 part is the domain, so this means that only positive values of x can be inputted in the function.
If only positive values can be inputted in the function, then the range will be: y > 3
Answer:
26*26*25 = 16,900
Step-by-step explanation:
First, we focus on the first initial, we have 26 letters that could fit in (the whole alphabet).
In the last initial we <em>can't</em> have the same we have in the first one, so we have 25 letters (the whole alphabet minus the letter that we already choose in the first initial
).
We have <em>no restrictions</em> for the middle one, so again we have 26 letters that could fit in.
So, we have 26*26*25 combinations (we multiply them because they happen all at the same time)
There is no need to use factorials, but we can use them if you want to.
Let's notice that 26! = 26*25*24*23*22*...
In our calculation, we only need the two first factors, so we can divide by 24! =24*23*22*21*...
Therefore,
26*26*25 = 26 * 26! /24!
