3\sqrt{2} - 2\sqrt{18} + 6\sqrt{8}[/tex]
Stella [2.4K]

Answer:

\sf \bold 9\sqrt{2}

Step-by-step explanation:

<h3>Simplifying radicals</h3>

    Step1: Prime fatorize and reduce to simplest form

    Step2:  Combine like radicals

    \sf 3\sqrt{2} - 2\sqrt{18}+6\sqrt{8}= 3\sqrt{2}- 2\sqrt{3*3*2}+6\sqrt{2*2*2}

                                    \sf = 3\sqrt{2}-2*3\sqrt{2} +6*2\sqrt{2}\\\\=3\sqrt{2}-6\sqrt{2}+12\sqrt{2}\\\\=(3-6+12)\sqrt{2}\\\\ = 9\sqrt{2}

..vertex: (4, -1)<br> f(3) = -6
s344n2d4d5 [400]

Answer:

\huge\boxed{f(x)=-5(x-4)^2-1=-5x^2+40x-81}

Step-by-step explanation:

The vertex form of an equation of a parabola:

f(x)=a(x-h)^2+k

(h;\ k) - vertex

We have

vertex (4;\ -1)\to h=4;\ k=-1

f(3)=-6

Therefore we have:

f(x)=a(x-4)^2+(-1)=a(x-4)^2-1

Substitute x=3 and f(3)=-6

a(3-4)^2-1=-6\qquad|\text{add 1 to both sides}\\\\a(-1)^2=-6+1\\\\a(1)=-5\\\\a=-5

Finally:

f(x)=-5(x-4)^2-1=-5(x^2-2(x)(4)+4^2)-1\\\\=-5(x^2-8x+16)-1=-5x^2+(-5)(-8x)+(-5)(16)-1\\\\=-5x^2+40x-80-1=-5x^2+40x-81

Find the error &amp; explain why it is wrong:
olga nikolaevna [1]

( { \frac{4 {x}^{3} }{ {y}^{4} }) }^{ - 2}  =  \frac{16x {}^{6} }{ {y}^{8} }

\frac{(4 {x}^{3})^{ - 2}  }{ { {(y}^{4} )}^{ - 2} }  =  \frac{16 {x}^{6} }{ {y}^{8} }

\frac{ {16x}^{ - 6} }{ {y }^{ - 8} }  = \frac{ {16x}^{6} }{ {y}^{8} }

The power of -2 was mistook as 2.
