Asked by Aaryan | 1 year ago | 47
##### Solution :-
10P4
We know that, 10P4 can be written as P (10, 4)
By using the formula,
P (n, r) = $$\dfrac{ n!}{r!(n – r)!}$$
P (10, 4) = $$\dfrac{ 10!}{(10 – 4)!}$$
= $$\dfrac{10!}{6!}$$

# Find all the points of discontinuity of f defined by
Question:
Find all the points of discontinuity of $f$ defined by $f(x)=|x|-|x+1|$.
Solution:
The given function is $f(x)=|x|-|x+1|$
The two functions, g and h, are defined as
$g(x)=|x|$ and $h(x)=|x+1|$
Then, f = − h
The continuity of g and is examined firs... | open-web-math/open-web-math | |

$2 - \sqrt{14}$
Here's how I did it:
#### Explanation:
First, let's split this multiplication process up:
$\sqrt{7} \cdot 2 \sqrt{7} = 2 \cdot 7 = 14$
$\sqrt{7} \cdot - 3 \sqrt{2} = - 3 \sqrt{14}$

# What Is 2 3/4 In Decimal Form?
2.75
Because 2 is the whole number so it has to be before the decimal. If you divide 100 into fourths (because it is the denominator) you get 25. 25*3=75. Since the original part of the problem we solved was a fraction it has to be behind the decimal which makes our answer 2.75.
