Felix's parents opened a savings
Crazy boy [7]

The money in the Felix's account will be $6798 when he is 21.

<u>Step-by-step explanation:</u>

It is given that,

  • The amount deposited is $2000.
  • The account earns 6%  compound interest.
  • It is compounded  annually for 21 years.

<u>To find the money in Felix's account after 21 years :</u>

The formula used here is,

⇒ A = P(1+r/n)^{nt}

where A is the amount after 21 years.

  • P is the initial amount deposited ⇒ P = 2000
  • r is the rate ⇒ r = 0.06
  • n is the number of times interest is compounded per year⇒ n = 1
  • t is the time period ⇒ t = 21

⇒ 2000(1+0.06/1)^{21\times 1}

⇒ 2000(1.06)^{21}

⇒ 2000\times3.399

⇒ 6798

Therefore, The money in the Felix's account will be $6798 when he is 21.

GarryVolchara [31]

Answer:

\displaystyle{f(x+1)=|x-6|-4}

To evaluate \displaystyle{f(x+1)}, substitute \displaystyle{x} to \displaystyle{x+1} so we should have:

\displaystyle{f(x+1) = |x+1-7|-4}

Evaluate the expression and finally, we have:

\displaystyle{f(x+1)=|x-6|-4}
