Answer:

<h3>$ 42.625 is the correct answer .</h3>

Step-by-step explanation:

principal ( p ) = $3100

Rate ( R ) = 5.5 %

Time ( T ) = 3 months

( convert months into year)

= 3/12 year

Simple Interest ( I ) = ??

By using formula ,

simple Interest ( I) = PTR / 100

=$3100 × 5.5 % × 3/12 ÷ 100

= 3100 × 5.5 × 3 ÷ 100 × 12

= 51150 ÷ 1200

= 42.625

= $ 42.625

Thank you ☺️☺️☺️

Let f(x) = 2x2 + x − 3 and g(x) = x + 2.<br><br> Find (f • g)(x)
katen-ka-za [31]

Answer:

(f\cdot g)(x) =  2x^3 + 5x^2-x-6

Step-by-step explanation:

We are given the two functions:

f(x)=2x^2+x-3\text{ and } g(x)=x+2

And we want to find:

(f \cdot g)(x)

Recall that this is equivalent to:

=f(x)\cdot g(x)

Substitute. Hence:

(f\cdot g)(x)= (2x^2+x-3)(x+2)

Expand if desired:

\displaystyle = x(2x^2+x-3)+2(2x^2+x-3) \\ \\ = (2x^3+x^2-3x)+(4x^2+2x-6) \\ \\\ = 2x^3 + 5x^2-x-6
