Let f(x)=3x-6 and g(x)=x-2. Find the value of f/g and its domain
Ket [755]
F(x) = 3x - 6
g(x) = x - 2

\frac{f(x)}{g(x)}= \frac{3x-6}{x-2} \\  \\ 
= \frac{3(x-2)}{x-2}  \\  \\ 
=3

This means the value of the ratio f(x)/g(x) will be equal to 3.

Domain of the fraction is Set of All real numbers except 2. At 2 the given fraction will be undefined as the denominator in the very first fraction will be zero. Another reason 2 is not a part of the domain is that it will make x-2 equal to zero and we cannot cancel out 0 with 0 from numerator and denominator.

In interval notation, the domain will be: (-∞,2)∪(-2 ,∞)

What is the value of $750 invested into an account with an annual rate of 3.25% compounded continuously for 4 years and 3 months
Goshia [24]

Answer:

$861.09

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

A = Pe^{rt}

<em>A = total </em>

<em>P = principal amount </em>

<em>r = interest rate (decimal) </em>

<em>t = time (years) </em>

<em />

First, change 3.25% into its decimal form:

3.25% -> \frac{3.25}{100} -> 0.0325

Next for <em>t, </em>we can use 4.25 since 4 years and 3 months is 4.25 in its decimal form. Now lets plug in the values:

A=750e^{(0.0325)4.25}

A=861.09

Your answer is $861.09
