$4q = 52$

Divide sides by 4

$\frac{4q}{4} = \frac{52}{4} \\$

Simplification

$q = 13$

Complete the table below by calculating the commission and adding it to the price of the stock.

We calculate the commission and adding it to the price of the stock to get total cost.

No Price Total Commission Total cost

100 $26.25 0.06 x $2,625 = $157.50 2625 + 157.50 =2782.5

100 $19.32 0.06 x $1,932 = $115.92 1932 + 115.92 =2047.92

40 $9.77 0.06 x $390.80 = $23.45 390.80 + 23.45= 414.25

200 $5.39 0.06 x $1,078 = $64.68 1,078 + 64.68 = 1142.68

100 $33.44 0.06 x $3,344 = $200.64 3,344 + 200.64 = 3544.64

In two or three sentences explain how you would solve for the real solutions of the following equation: please help asap!!

g100num [7]

the real solutions for the equation $x^{3}=-64$ are -

$x=4,2+-2\sqrt{3i}$

Step-by-step explanation:

$x^{3}$ = $- 64$

$x^{3} +64$ = 0

We can write 64 as $4^{3}$

$x^{3}$ + $4^{3}$ = 0

using the identity ( $x^{3}+y^{3} = (x+y)(x^{2} -xy+y^{2} )$ )

we get,

= $(x+4) (x^{2} -x*4+4^{2} )$

= $(x+4)(x^{2} -4x+16)$ ....................(1)

solving the quadratic equation ,

$x^{2} -4x+16$ =0

solutions of this quadratic equation can be obtained by

$x=-b +- \sqrt{b^{2}-4ac } /2a$

let use y for factors

$x=-(-4x)+-\sqrt{(-4x^{2} )-4*x^{2} *16} / 2*x^{2}$

$x=4x+-\sqrt{16x^{2} -64x^{2} } /2x^{2}$

$x=4+-\sqrt{16-64}/2$

$x=4+-4\sqrt{3i} /2$

<u /> $x=2+-2\sqrt{3i}$ ..................(2)

from the equation 1 we have,

$x-4=0$

which gives solution $x=4$

and from equation 2 we got $x=2+-2\sqrt{3i}$

so the real solutions for the equation $x^{3}=-64$ are -

$x=4,2+-2\sqrt{3i}$
