Answer:

A: y+4=4(x+3)

Step-by-step explanation:

Point-Slope Formula:

y-y1=m(x-x1)

Substitute:

y-(-4)=4(x-(-3))

-(-)=+

Determine the value of base x if (211)x = (6A)16

igor_vitrenko [27]

$211_x=2x^2+x+1$
$6A_{16}=106_{10}$

$\implies 2x^2+x+1=106\iff 2x^2+x-105=(x-7)(2x+15)=0$

This has two solutions, $x=7$ and $x=-\dfrac{15}2$ .

FURNITURE A modern table is constructed with four legs made

Troyanec [42]

The volume of a shape is the amount of space in it.

The expression that represents the volume of one table leg is: $V = l^3 + n^3$
The sides of the legs is 14.37 inches long

<u>(a) The volume of one table leg</u>

Represent the side length of the leg with l, and the side length of the notch with n.

So, the expression that represents the volume of one table leg is:

$V = l^3 + n^3$

<u>(b) The length of the sides</u>

From the question, we have:

$n = 40\% \times l$

Express 40% as decimal

$n = 0.40 \times l$

$n = 0.4l$

Substitute 0.4l for n in $V = l^3 + n^3$

$V =l^3 + (0.4l)^3$

$V =l^3 + 0.064l^3$

$V =1.064l^3$

The volume of the 4 legs is given as: 12636

So, the volume of one leg would be 12636/4

So, we have:

$1.064l^3 = \frac{12636}{4}$

$1.064l^3 = 3159$

Divide both sides by 1.064

$l^3 = 2968.985$

Take cube roots of both sides

$l = 14.37$

Hence, the sides of the legs is 14.37 inches long
