Step-by-step explanation:
Let t represent the time it took Emanuel to drive home from college. If the total round trip took 11 hours, it means that the time it took
Emanuel to drive from home back to college would be (11 - t) hours.
Emanuel drove home from college traveling an average speed of 70 mph.
Distance = speed × time
Distance covered by driving from college to home is
70 × t = 70t
He drove back to the college the following week at an average speed of 62.7 mph.
Distance covered by driving back to college from home is
62.7(11 - t) = 689.7 - 62.7t
Since the distance travelled is the same, then
689.7 - 62.7t = 70t
70t + 62.7 = 689.7
132.7t = 689.7
t = 689.7/132.7
t = 5.19 hours.
Therefore, the time that it took Emanuel to drive from home back to college is
11 - 5.19 = 5.81 hours
I hope the last thing on the third answer is ... less than or equal to 0. If it is greater than 0, then you get into complex numbers and the result is not a graph that you can make yet. Just so you know what the graph looks like, I've included it.
C (or third one down) <<<< answer.
Answer:
Step-by-step explanation:
When the interest compounds continuously, our formula is

If we start with 10000 and are looking for how long, t, it takes to double, we are looking for how long it will take for our account to have 2 times 10000. That's 20000. Therefore, our equation is

Divide both sides by 10000 to get

Take the natural log of both sides to "undo" that e:

Again, since ln and e undo each other what we have now is
ln(2) = .11t and
so
t = 6.3 years
