Simplify (x - y)^2 - 2(x - y) + 1

Rus_ich [418]

Answer:

(x-y-1)^2 or [(x-y)-1]^2

Step-by-step explanation:

We are given the expression:-

$\displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 }$

Let A = (x-y)^2

$\displaystyle \large{ A^{2} - 2 A+ 1 }$

From:-

$\displaystyle \large{ {x}^{2} - 2x + 1 = {(x - 1)}^{2} }$

Thus:-

$\displaystyle \large{ {A}^{2} - 2A + 1 = {( A- 1)}^{2} }$

Rewrite A in (x-y)^2.

$\displaystyle \large{ {(x - y)}^{2} - 2(x - y) + 1 = {( (x - y) - 1)}^{2} }$

P(ANB) =3/10

Free_Kalibri [48]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

This is a question from conditional probability.

We are given:

$P(A \cap B) = \frac{3}{10}$

$P(B)=\frac{2}{5}$

And, we need to find P(A | B)

According to the formula of conditional probability:

$P(A|B)=\frac{P(A \cap B)}{P(B)}$

Using the values, we get:

$P(A|B)=\frac{\frac{3}{10} }{\frac{2}{5} }\\\\P(A|B)=\frac{3}{4}$

Thus, the probability of occurrence of event A given that event B has already occurred is $\frac{3}{4}$

I put $500 in a saving account that warns 7% interest compounded quarterly. How much will be in the account after 1 year? Rounde

Fantom [35]

$\bf ~~~~~~ \textit{Compound Interest Earned Amount}
\\\\
A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$500\\
r=rate\to 7\%\to \frac{7}{100}\to &0.07\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{quarterly, thus four}
\end{array}\to &4\\
t=years\to &1
\end{cases}
\\\\\\
A=500\left(1+\frac{0.07}{4}\right)^{4\cdot 1}\implies A=500(1.0175)^4\implies A\approx 535.92951564$

32-7×4+42÷6×3<br> Working out

Dimas [21]

With this problem you will need to use the order of operations, or PEMDAS.

P= parentheses

E= Exponents

M= Multiplication

D= Division

A= Addition

S= Subtraction

There is no parentheses or exponents, so mark those out.

I am not so great with working things out like this problem, but i am sure that the person above/below did work it out correctly.

I can give you the answer though.

Answer= 25

Sorry if that answer is incorrect

Hoped this helped.... Sorta,
