Given the function f(x)=x2+2x+1, find:<br> f(2b)

Maru [420]

Hey there!!

Given equation :

f ( x ) = x² + 2x + 1

Find f ( 2b )

In order to solve this question, we will need to replace the value 2b instead of x

... f(2b) = ( 2b )² + 2 ( 2b ) + 1

... f(2b)= 8b² + 4b + 1

Hope my answer helps!

Answer:

$\large\boxed{h=\dfrac{\sqrt{703}}{2}ft\approx13.26ft}$

Step-by-step explanation:

Look at the picture.

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have:

$leg=\dfrac{9}{2}ft\\\\hypotenuse=14ft\\\\leg=h$

Substitute:

$\left(\dfrac{9}{2}\right)^2+h^2=14^2$

$\dfrac{81}{4}+h^2=196$ <em>multiply both sides by 4</em>

$81+4h^2=784$ <em>subtract 81 from both sides</em>

$4h^2=703$ <em>divide both sides by 4</em>

$h^2=\dfrac{703}{4}\to h=\sqrt{\dfrac{703}{4}}\\\\h=\dfrac{\sqrt{703}}{\sqrt4}\\\\h=\dfrac{\sqrt{703}}{2}\\\\h\approx13.26$
