Yes, any number that can be represented as a ratio of two integers is rational...

7.8

7 8/10

78/10

39/5

You can also be aware that any terminating number (including terminating decimals) or any number with a repeating decimal pattern is rational.

Yes, it is. Because you can write it in the form of p/q as
78/10
= 39/5

Answer:

Given:

R(x) = 59x - 0.3x²
C(x) = 3x + 14

Find the following:

P(x) = R(x) - C(x) = 59x - 0.3x² - 3x - 14 = -0.3x² + 56x - 14
R(80) = 59(80) - 0.3(80²) = 2800
C(80) = 3(80) + 14 = 254
P(80) = 2800 - 254 = 2546

HELP PLEASE, Part a of the question was posted earlier on.

$\bf \lim\limits_{x\to 6}~\cfrac{x^2+x+42}{x-6}\implies \lim\limits_{x\to 6}~\cfrac{(x+7)(x-6)}{(x-6)}\implies \lim\limits_{x\to 6}~x+7
\\\\\\
\lim\limits_{x\to 6}~(6)+7=13
\\\\\\
\textit{since the original equation holds for all, }x\ne 6,\textit{ then it approaches}\\
\textit{the same limit as }x+7$
