the domain for a rational expression will be the values of "x" that can safely be taken without setting the denominator to 0, since if that occurs the rational becomes undefined, well we can simply set the denominator to 0 and check which values are those.
[tex]\cfrac{x^2-x-20}{5x^2+18x-8}\implies \cfrac{(x-4)(x-5)}{(x+4)(5x-2)} \\\\\\ \stackrel{\textit{setting the denominator to 0}}{(x+4)(5x-2)=0}\implies x= \begin{cases} -4\\ \frac{2}{5} \end{cases}~\hfill \stackrel{\mathbb{DOMAIN}}{\{x|x\in \mathbb{R};x\ne -4,\frac{2}{5}\}}[/tex]

Calculate the simple interest rate. (Round your answer to one decimal place.)
P = $3600, I = $330, t = 1 year
Answers
Answer:R = 9.1667%/year
Step-by-step explanation:
Solving our equation
r = 330 / (3600 × 1) = 0.09166667
r = 0.09166667
converting r decimal to a percentage
R = 0.09166667 × 100 = 9.1667%/year
The interest rate required to
accumulate simple interest of $330.00
from a principal of $3,600.00
over 1 years is 9.1667% per year.

The number of students at Yellowstone High School has been increasing by 4% each year. There are
currently 4,256 students. How many students will there be in 8 years?
Answers
Answer:
5,617.92
Step-by-step explanation:
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
Solving our equation:
A = 4256(1 + (0.04 × 8)) = 5617.92
A = $5,617.92
The total amount accrued, principal plus interest, from simple interest on a principal of $4,256.00 at a rate of 4% per year for 8 years is $5,617.92.
