If Tanisha has ​$nbsp 100 100 to invest at 66​% per annum compounded semiannuallysemiannually​, how long will it be before she h
Oxana [17]

Answer:

time is 6.76 years

Step-by-step explanation:

given data

amount = $150

payment = $100

rate r = 6%  = 0.06

to find out

time period t

solution

we know it is compounding continuous

so we will apply here formula that is

amount = payment × e^{rt}   ..........1

put here all value we get

amount = payment × e^{rt}  

150 = 100 × e^{0.06t}  

take ln both side

ln 1.5 =  e^{0.06t}  

0.40546 = 0.06t

t = 0.40546 / 0.06

t = 6.76

so time is 6.76 years

Answer:

Step-by-step explanation:

Calculus....finally something FUN to answer!

This is integration, but here you have the area under the curve, you just don't have the upper bound. Setting that problem up looks like this:

28=\int\limits^b_1 {7x} \, dx  and using the First Fundamental Theorem of Calculus, that will integrate to look like this:

28=\frac{7x^2}{2} from 1 to b and applying the FTC:

28=\frac{7b^2}{2}-\frac{7}{2}  Multiplying everything by 2 to get rid of the denominators gives you:

56=7b^2-7\\\\56=7(b^2-1)\\8=b^2-1\\9=b^2\\b=3
