F(x)=4x+1
g(x)=x^2-5
(f . g)(x)=?

(f . g)(x) = f(x) . g(x) = (4x+1).(x^2-5)=(4x).(x^2)+(4x).(-5)+(1).(x^2)+(1).(-5)
(f . g)(x) = 4x^(1+2)-20x+x^2-5
(f . g)(x)=4x^3+x^2-20x-5

Answer: Option A. 4x^3+x^2-20x-5

Given b(x)=√3x+3 evaluate f(11) I really need help with this.

andre [41]

Step-by-step explanation:

$\huge{\purple{\underline{\underline{\bf{\pink{Answer}}}}}}$

in we have x = 11

put the value of x in equation

$b(11) = \sqrt{3} (11) + 3$

$b(11) = 11 \sqrt{3} + 3$

so x = 11√3

Hope it helps

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence

Sindrei [870]

ANSWER

$a_{55}=161$

EXPLANATION

The general term for the sequence is

$a_n=-1+3(n-1)$

To find the 55th term, we have to substitute
$n = 55$
in to the general term and simplify.

This implies that,

$a_{55}=-1+3(55-1)$

$a_{55}=-1+3(54)$

$a_{55}=-1+162$

$a_{55}=161$

Therefore the 55th term is 161.
