Answer:
v(0) = 32,000 . . . dollars
v(13) = 16,427 . . . dollars
Step-by-step explanation:
The initial value is the value of the function for t=0. Put that into the formula and evaluate.
v(0) = 32,000(0.95^0) = 32,000 . . . . dollars
__
The value after 13 years is the function value for t=13. Put that into the formula and evaluate.
v(13) = 32,000(0.95^13) ≈ 32,000·0.513342 ≈ 16,427 . . . . dollars
Answer: 2 19/24 hours was spent in practising.
Step-by-step explanation:
During the first hour, they practiced for 5/8 of an hour. During the second hour, they practiced for 2/3 of an hour. This means that the total time for which they practiced in the first 2 hours would be
5/8 + 2/3 = 31/24 hours
During the last two hours, they first practiced for 3/5 of an hour, took a 1/2 hour break and then practiced the rest of the time. This means that the rest of the time for which they practiced is
2 - (3/5 + 1/2) = 2 - 11/10 = 9/10
Therefore, the time they spent practicing in total would be
31/24 + 3/5 + 9/10 = 67/24 =
2 19/24 hours
No . . . while the difference represents the absolute magnitude between two numbers . . . for example . . .
<em>The difference between 5 and 2 is . . . 3</em>
<em>The difference between 6.4 and 9.5 is . . . 3.1</em>
. . . there is still the chance that the difference may be zero . . . in which case the difference is neither positive nor negative
. . . so in short . . . the answer is . . . <u><em>NO</em></u>
