The square root of a product of two positive real numbers is the product of their square roots. Write an algebraic expression ba
Sliva [168]

Step-by-step explanation:

  • The square root of a product of two positive real numbers is the product of their square roots.

Let 4 and 5 be the two positive real number. The square root of a product of 4 and 5 is the product of their square roots.

\sqrt{4\cdot 5}

=\sqrt{20}

=\sqrt{2^2\cdot \:5}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}

=\sqrt{5}\sqrt{2^2}

so

=\sqrt{5}\sqrt{2^2}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a

\sqrt{2^2}=2

Therefore,

\sqrt{4\cdot \:5}=2\sqrt{5}

NOW SOLVING BY APPLYING RADICAL RULE such that

\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}

\sqrt{4\cdot 5}=\sqrt{4}\sqrt{5}

as

\sqrt{2^2}=2

so

     =2\sqrt{5}            

Hence, The square root of a product of two positive real numbers is the product of their square roots.

PLEASE HELP!!
Aloiza [94]

Answer:

From the given graph:

the coordinates of triangle RST are;

R= (2, 1),

S= (2,-2),

T= (-1,-2)

Given: Scale factor = \frac{5}{3}  and center of dilation at (2,2)

The mapping rule for the  dilation applied to the triangle as shown below:    

(x,y) \rightarrow (\frac{5}{3}(x-2)+2 , \frac{5}{3}(y-2)+2 ); where k represents the scale factor i.e, k=\frac{5}{3} or we can write it as ;  

For R=(2, 1)      

The image R' = (\frac{5}{3}(2-2)+2 , \frac{5}{3}(1-2)+2 )

⇒ R'= (2, \frac{1}{3})  

Similarly for S= (2, -2) and T= (-1,-2)

therefore, the image of S'= (\frac{5}{3}(2-2)+2 , \frac{5}{3}(-2-2)+2 )

⇒ S'= (2, \frac{-14}{3})

The image of T' =(\frac{5}{3}(-1-2)+2 , \frac{5}{3}(-2-2)+2 )

⇒T' = (-3, \frac{-14}{3})

Now, labelling the image of triangle R'S'T' as shown in the figure given below
