Step-by-step explanation:

Sale price

= Marked down by 10% from selling price

= 90% of selling price

= 0.9 * $600

= $540.

Sale price - Cost price

= $540 - $450 = $90.

The markup from cost to sale is $90.

3w^4*5x^8*w^7*2x

dexar [7]

Answer:

The simplified expression is $30w^{11}x^9$

Therefore the simplified expression to the given expression is $3w^4.5x^8w^7.2x=30w^{11}x^9$

Step-by-step explanation:

Given expression is $3w^4.5x^8w^7.2x$

To simplify the given expression as below :

$3w^4.5x^8w^7.2x$

First combine the like terms to simplify the expression easily we get

$=(3.5.2)(w^4.w^7)(x^8.x)$

$=30(w^{4+7})(x^{8+1})$ ( by using the property $a^m.a^n=a^{m+n}$ )

$=30w^{11}x^9$

Therefore the simplified expression is $30w^{11}x^9$

Therefore the simplified expression to the given expression is $3w^4.5x^8w^7.2x=30w^{11}x^9$

Find the values of the six trigonometric functions of theta based on the following constraints:

Alexxx [7]

Hello,

1)
sin x=3/5==>x=126.869897...° (since in quadrant II)

2)==>cos x<0
cos x=-√(1-sin ² x)=-√(1-9/25)=-4/5

tan x=(3/5)/(-4/5)=-3/4

cotg x=-4/3 =1/tan x

sec x=1/cos x=-5/4

cosec x=1/sin x=5/3
