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

How do I do this? Please explain it. Thank you.

Westkost [7]

Answer:

slope = - $\frac{14}{3}$

Step-by-step explanation:

the slope of the secant line in the closed interval [a, b ] is

slope = $\frac{f(b)-f(a)}{b-a}$

here [a, b ] = [1, 4 ]

f(b) = f(4) = - $2^{4}$ + 5 = - 16 + 5 = - 11

f(a) = f(1) = - $2^{1}$ + 5 = - 2 + 5 = 3

slope = $\frac{-11-3}{4-1}$ = $\frac{-14}{3}$ = - $\frac{14}{3}$

The perimeter of a rectangle is 48 m. The width of the rectangle is 2 more than half the length. Find the length and the width

Ksivusya [100]

Answer:

Length = 14.6667

Width = 9.33333

Step-by-step explanation:

let the length be x

Width = (x/2)+2

Perimeter = 2(L+W)

Perimeter = 2(x+(x/2+2)) =48

2[(3/2)x + 2] =48

3x+4= 48

3x = 44

x =14.666667

width = (14.666667/2)+2

Width = 9.333333
