Answer:

$7x-7$

Step-by-step explanation:

We have been given that $PR=4x-2$ and $RS=3x-5$ . We are asked to find the expression that represents length of PS.

We know that $PS=PR+RS$ .

Upon substituting our given values in above equation, we will get:

$PS=4x-2+(3x-5)$

$PS=4x-2+3x-5$

$PS=4x+3x-2-5$

$PS=7x-7$

Therefore, the expression $7x-7$ represents length of PS.

P is inversely proportional to the cube of (q-2) p=6 when q=3 find the value of p when q is 5

$\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
\\
&&y=\cfrac{{{ k}}}{x}
\end{array}\\\\
-----------------------------\\\\
\textit{p is inversely proportional to the cube of (q-2)}\implies p=\cfrac{k}{(q-2)^3}
\\\\\\
now \quad 
\begin{cases}
p=6\\
q=3
\end{cases}\implies 6=\cfrac{k}{(3-2)^3}$

solve for "k", to find k or the "constant of variation"

then plug k's value back to $\bf p=\cfrac{k}{(q-2)^3}$

now.... what is "p" when q = 5? well, just set "q" to 5 on the right-hand-side, and simplify, to see what "p" is

Malik deposited 1050 in a savings account and it earned 241.50 in simple interest after four years. Find the interest after four

kap26 [50]

Answer:

if it's true simple interest then each year's interest is the same so interest for one year is a quarter of 241.50 which give you the rate but if each year's interest in left in the account the result will be different , it is a really poorly worded question
