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

A bacteria culture starts with 500 bacteria and doubles in size every half hour.1

(a) How many bacteria are there after 3 hours?

We are told “. . . doubles in size every half hour.” Let’s make a table of the time and population:

t 0 0.5 1.0 1.5 2.0 2.5 3.0

bacteria 500 1000 2000 4000 8000 16000 32000

Thus, after three hours, the population of bacteria is 32,000.

(b) How many bacteria are there after t hours?

In t hours, there are 2t doubling periods. (For example, after 4 hours, the population has doubled 8

times.) The initial value is 500, so the population P at time t is given by

P(t) = 500 · 2

It's winter and the powder on Vail Mountain has never been better. You decide to measure the snowfall over a three hour period t

The best answer is Option A.

Step-by-step explanation:

Increased height of snow = 17 inches

First increase = 5% = 0.05 (Converting the percentages dividing by 100)

Second increase = 8% = 0.08

Third increase = 11% = 0.11

We will first start from where the snowfall has end, therefore,

Third increase = 11% of 17 inches

Third increase = $0.11*17=1.8\ inches$

Subtracting from original height of snow = 17 - 1.8 = 15.2 inches

Second increase = 8% of height before third increase

Second increase = $0.08*15.2 = 1.2\ inches$

Height before second increase = 15.2 - 1.2 = 14 inches

First increase = 5% of height before second increase

First increase = $0.05*14 = 0.7\ inches$

Height before first increase = 14 - 0.7 = 13.3 inches

The snow was 13.3 inches high before it started to snow.

The best answer is Option A.
