How many years will it take for an initial investment of $20000 to grow to $50000? Assume a rate of interest of 17% compounded c
Gemiola [76]

Answer:

Years = natural log (total / principal) / rate

Years = natural log (50,000 / 20,000) / .17

Years = natural log (2.5) / .17

Years = (0.9162907319) / .17

Years = 5.3899454818 =

Years = 5.4 (rounded)

I kind of understand this question, but I'm not sure how to answer it directly, can someone help please.
nordsb [41]
So here we use the pythagorean theorem which is a2 + b2 = c2 (“a” squared times “b” squared equals “c” squared) the length from calvins house to the intersection is “a” and the length from phoebes house to the intersection is “b” so in order to find out the length of “c” (calvins house to phoebes house) we need to use the pythagorean theorem

a2 275x275=75,625

b2 113x113 = 12,769

so now that we have figured out what a2 and b2 are let’s add them

75,625 + 12,769 = 88,394

now since we only need to find out the length and not the area we need to find the square root of 88,394

the square root of 88,394 is 297.311 (i cut off the decimal after three places)

the direct length from phoebes house to calvins is 297.311 meters
