If mx=x+5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)

Ne4ueva [31]

Answer:c

Step-by-step explanation:

Given

$m\left ( x\right )=x+\frac{5}{x-1}$

and $n\left ( x\right )=x-3$

m of n is given by replacing x in $m\left ( x\right )$ by x-3

$m\left ( n\left ( x\right )\right )=x-3+\frac{5}{x-3-1}=x-3+\frac{5}{x-4}$

$m\left ( n\left ( x\right )\right )$ can take any value of x except x=4 because at x=4 function is not defined

and $h\left ( x\right )=\frac{11}{x-4}$ is also not defined for x=4 and can take any value of x

If my saving x$ grows 10% every year how much will I have in:<br> 1 year<br> 2 year<br> 5 year

mote1985 [20]

Answer:

$1.1x, 1.21x, 1.61051x$

Step-by-step explanation:

If you saving grows $10 \%$ every year, then your saving is $1.1\\$ times your saving from last year. Therefore, after one year, you will have $1.1x\\$ , then after $2$ years, you will have $(1.1)^2 \cdot x=1.21x$ , then after $5$ years, you will have $(1.1)^5 \cdot x = 1.61051x$ .
