Answer:
(f - g)(x) = -x² + 2x + 3
Step-by-step explanation:
Step 1: Define
f(x) = 2x + 3
g(x) = x²
(f - g)(x) = f(x) - g(x)
Step 2: Set up expression (Substitute)
(f - g)(x) = f(x) - g(x)
(f - g)(x) = 2x + 3 - x²
Step 3: Simplify
(f - g)(x) = -x² + 2x + 3
Answer:
x=3
Step-by-step explanation:
Time is continuous.
If it was possible to measure EXACTLY the time it
takes a person (or group of people) to evaluate 27 + 72 (=99), the
time(s) people took could be 2 seconds, 3 seconds, 2.5 seconds, 2.25
seconds, 2.22 seconds, 2.2199999 seconds... In other words, any value is
possible when measuring "exact" time elapsed.
However, people are
limited by the tools they use. There isn't a tool without limits in its
ability to measure time elapsed. For example, is the stopwatch accurate
to 1/100th of a second? 1/1000th of a second? At some point it reaches
its limit. The constraints of the tool being used to measure are going
to, in fact, cause data to be "discrete."
I'm 90% sure you're
teacher is looking for "continuous" as the solution though. So don't
bring up "discrete" unless you feel like you'll be able to confidently
explain the second paragraph above.
Subtract 125,300 from 800,009. From there you find that they made 674,709 in profit.
Answer is 674,709
