worty [1.4K]

Answer:

A = 1/2a^4

B= 2/a^2

Step-by-step explanation:

a= 2^(m)

  • A =1/2*16^m= 1/2*(2^m)^4 =1/2 a^4
  • B =2/(∛64)^m = 2/(2^6/3)^m = 2/2^2m = 2/a^2

7100 dollars is placed in an account with an annual interest rate of 5%. To the nearest tenth of a year, how long will it take f
kow [346]

Answer:

After 26.91\ years the principle amount value will reach to 26400\ dollars.

Step-by-step explanation:

Given that,

                 Principle Amount (P)= 7100\ dollars

                 Rate of Interest (R)= 5%

                 Total Amount (A)= 26400\ dollars

If Principle Amount (P) =P\ dollars, Time =t\ years, Rate of Interest =R% pa

when interest is compounded annually:

Total Amount after t\ years = P(1+\frac{R}{100}) ^{t}

Now,

         A= P(1+\frac{R}{100}) ^{t}

     ⇒ 26400=7100(1+\frac{5}{100}) ^{t}

     ⇒ 3.7183=(1+0.05)^{t}

     ⇒ 3.7183=(1.05)^{t}

taking log both sides, we get

         ln(3.7183)=ln {(1.05)^{t}}

     ⇒ 1.31327=t\times ln(1.05)

     ⇒ 1.31327=t\times 0.04879

    ⇒ t=26.91

Therefore,

After 26.91\ years the principle amount value will reach to 26400\ dollars.
