_____ divide both sides by 2 to get n by itself on one side
2

n<19

Check:

Mai wants to make an open top box by cutting out corners of a square piece of cardboard and folding up the sides. The cardboard

Bumek [7]

Answer:

$V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

The domain for x is all real numbers greater than zero and less than 5 com

Step-by-step explanation:

<em><u>The question is</u></em>

What is the volume of the open top box as a function of the side length x in cm of the square cutouts?

see the attached figure to better understand the problem

Let

x -----> the side length in cm of the square cutouts

we know that

The volume of the open top box is

$V=LWH$

we have

$L=(10-2x)\ cm$

$W=(10-2x)\ cm$

$H=x)\ cm$

substitute

$V(x)=(10-2x)(10-2x)x\\\\V(x)=(100-40x+4x^{2})x\\\\V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

Find the domain for x

we know that

$(10-2x) > 0\\10> 2x\\ 5 > x\\x < 5\ cm$

so

The domain is the interval (0,5)

The domain is all real numbers greater than zero and less than 5 cm

therefore

The volume of the open top box as a function of the side length x in cm of the square cutouts is

$V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

Can you please help me with this

Vitek1552 [10]

Answer:

log9

Step-by-step explanation:

Using the rules of logarithms

logx + logy = log(xy)

logx - logy = log( $\frac{x}{y}$ )

log $x^{n}$ ⇔ nlogx

Given

2(log18- log3) + $\frac{1}{2}$ log $\frac{1}{16}$

= 2(log( $\frac{18}{3}$ ) ) + log $(\frac{1}{16}) ^{\frac{1}{2} }$

= 2log6 + log $\frac{1}{4}$

= log6² + log $\frac{1}{4}$

= log36 + log $\frac{1}{4}$

= log( 36 × $\frac{1}{4}$ )

= log9
