What is the x-intercept of<br> 3x – 4y = 242

Andreas93 [3]

Answer:

x=242/3

alternative form= 80 2/3, x=80.6

Step-by-step explanation:

3x-4y=242

substitute y = 0

3x-4x0=242

calculate the product

3x-0=242

remove 0

3x=242

divide both sides (by 3 in order to leave x by itself)

done

A closed box is constructed of 4200cm2 of cardboard. The box is a cuboid, with height hcm and square base of side xcm . What is

inysia [295]

Answer:

x is 10 $\sqrt{7}$

Step-by-step explanation:

Let x is the side of the base
Let h is the height

Given that:

The area A = 4200 cm2

<=> 2 $x^{2}$ + 4xh = 4200 cm2

<=> 4xh = 4200 - 2 $x^{2}$

<=> h = (4200 - 2 $x^{2}$ )/4x

The volume of the box:

V = $x^{2}$ h

<=> V = $x^{2}$ (4200 - 2 $x^{2}$ )/4x

<=> V = (4200x - 2 $x^{3}$ )/4

To find the maximum volume, we differentiate volume with respect to x:

dV/dx = (4200 - 6 $x^{2}$ )/4

Set dV/dx = 0, we have:

4200 - 6 $x^{2}$ =0

<=> $x^{2}$ = 700

<=> x = 10 $\sqrt{7}$

We differentiate again

d²V/dx² = -12x/4

It is negative so the volume is maximum.

So x is 10 $\sqrt{7}$
