Nitella [24]

Answer:

\$ 268

Step-by-step explanation:

Compound Interest: If P is initial amount, A is final amount, r is interest rate and n is number of years.

A=P(1+\frac{r}{100})^n

Here\ P=\$ 200,\ r=5\%\ and\ n=6\ years\\\\We\ have\ to\ find\ out\ A\\\\A=200(1+\frac{5}{100})^6\\\\A=200(1+0.05)^6\\\\A=200(1.05)^6\\\\A=200\times  1.340095641\\\\A=268.02\\\\A\approx \$ 268

Sergeu [11.5K]

Answer:

(f+g)(x)=6x-3

domain is (-∞,∞)

Step-by-step explanation:

f(x)=5x

g(x)=x-3

(f+g)(x)=f(x)+g(x)

to find f+g(x) we add both function

Substitute f(x) and g(x)

(f+g)(x)=f(x)+g(x)

(f+g)(x)=5x+x-3=6x-3

(f+g)(x)=6x-3

Domain is the set of x values

here there is no restriction for x

so domain is the set of all real numbers

domain is (-∞,∞)
