k = - 2 is excluded from the domain

the denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that k cannot be

solve k + 2 = 0 ⇒ k = - 2 ← excluded value

Sophia puts $250 in the bank with a 2.5% annual interest rate compounded monthly. If Sophia does not touch his money, how much m

Fittoniya [83]

Answer:

Step-by-step explanation:

Deposited amount initially (P) = $250.

Rate of interest(r) = 2.5% compounded monthly = 0.025

Number of years (t) = 4.

Number of months in an year (n) = 12.

Formula for compound interest:

$A=P(1+\frac{r}{n})^{nt}$ .

Plugging values in formula, we get

$A= 250(1+\frac{0.025}{12})^{12\times 4}$

$A= 250(1.00208)^{48}$

$A= 250\times \:1.10506$

A=276.26.

<h3>Therefore, correct option is D) $276.26.</h3>
