we are given

$f(x)=x^2+6x+15$

we can complete square

$f(x)=x^2+6x+9+6$

$f(x)=x^2+6x+3^2+6$

$f(x)=(x+3)^2+6$

so, graphing form is

$f(x)=(x+3)^2+6$ ..............Answer

Can you help me here pls? Asap

boyakko [2]

Step-by-step explanation:

% calculations are totally easy, if you remember to always find and the use 1%.

100% = $2.85

1% = 100%/100 = 2.85/100 = 0.0285

the price difference was

2.91 - 2.85 = $0.06

how many % are these $0.06 compared to yesterday's price ?

that is how many times 1% can fit into this number.

0.06 / 0.0285 = 2.105263158...%

so, rounded this is 2.1%

Rewrite \sqrt((1+cos45)/(2)) using a half-angle identity

$\stackrel{\textit{Half-Angle Identities}}{cos\left(\cfrac{\theta}{2}\right)=\pm \sqrt{\cfrac{1+cos(\theta)}{2}}} \\\\[-0.35em] ~\dotfill\\\\ \sqrt{\cfrac{1+cos(45^o)}{2}}~~ = ~~cos\left( \cfrac{45^o}{2} \right)\implies \sqrt{\cfrac{1+cos(45^o)}{2}}~~ = ~~cos(22.5^o)$
