B. somtimes
C. never

Answers

Answer 1
Answer: Integers are always rational!

A rational number is a number that can be expressed as (p)/(q), where p and q are both integers.

So each integer can be expressed as  (itself)/(1), which is always rational as "itself" if an integer!

Frank the lumberjack has a log that is 291 centimetres long. He cuts it into three pieces. Work out the length of the third piece if the first two pieces are 67cm and 181cm long.

Over which interval is the graph of f(x) = –x2 + 3x + 8 increasing? (–∞, 1.5)

(–∞, 10.25)

(1.5, ∞)

(10.25, ∞)

Answers

The answer for this question is (-infinity,1.5) because
when f(x) is increasing f'(x)  > 0
-2x + 3 > 0
-2x > -3
 x< 3/2 or 1.5

427 rounded to the nearest hundred

Answers

427  to the nearest hundred.

The hundred digit is 4. After the 4, is 2. And 2 is not up to 5, so we round down, by stepping down to zeros.

 ≈ 400 to the nearest hundred
400 because 427 is not closer to 500.
