Answer:

5i\sqrt{3}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

and \sqrt{-1} = i

Given

\sqrt{-75}

= \sqrt{25(3)(-1)}

= \sqrt{25}  × \sqrt{3} × \sqrt{-1}

= 5 × \sqrt{3} × i

= 5i\sqrt{3}

Rudik [331]
<h2>Answer:</h2>

f^{-1}  (x)=\sqrt{\frac{x}{14}}.

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

y=14x^2

<h3>2. Substitute y for x, and x for y.</h3>

x=14y^{2}

<h3>3. Solve for y.</h3>

14y^{2}=x\\ \\y^{2} =\frac{x}{14} \\ \\y=\sqrt{\frac{x}{14}}

<h3>4. Express your result.</h3>

f^{-1}  (x)=\sqrt{\frac{x}{14}}.

1oo divided into ratio 3:7
masha68 [24]
 <span>100 is not divisible by 3 when u divide 100 by 3 u get 33.333333...... not 3.33333..... 
the good explanation of your answer is that 0.999999....is equal to 1 
we can prove it by the following way: 
let x=0.9999.... 
then 10x = 9.999999..... 
subtract we will get 10x - x = 9.9999....- 0.99999...... 
which gives us 9x = 9 and therefore x =1 
i hope this will help u with your confusion.......  :)</span><span>
