Answer:

A) R = 1900 -24t

B) 1684 billion barrels

C) 79.17 years

Step-by-step explanation:

Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.

R = 1900 -24t

For t=9, the reserves will be ...

R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels

The reserve will be 0 when ...

0 = 1900 -24t

24t = 1900 . . . . . add 24t

t ≈ 79.17 . . . . divide by 24

Reserves will be gone in about 79.17 years.

How do I determine if a limit exist considering how it looks on a graph? Can I determine if a limit exists solely from the graph

Allushta [10]

Answer: See below

Step-by-step explanation:

1. At x=1, the limit does not exist. If you see an open circle on the graph like you do here, you know that the function is discontinuous. This graph actually shows a jump discontinuity at x=1.

2. You can determine if a limit exists by solely looking at the graph. Unfortunately in this case, f(1)=1 and $\lim_{x \to \ 1^-} f(x)$ are not equal to each other. Therefore, the limit does not exist.
