Consider the expression 2√ 3 cos(x)csc(x)+4cos(x)-3csc(x)-2 √ 3 This expression can be represented as the product of the factors
skad [1K]
The answer:
let be A(x) =<span>2√ 3 cos(x)csc(x)+4cos(x)-3csc(x)-2 √ 3

this function can be represented as </span><span>the product of the factors

proof   
</span>2√ 3 cos(x)csc(x)+4cos(x)-3csc(x)-2 √ 3 = 

2√ 3 cos(x)csc(x)+4cos(x)csc(x) / csc(x) -  3csc(x)- 2 √ 3 csc(x) / csc(x)
this method doesn't change nothing inside the function A(x)

so we have 
[ 2√ 3 cos(x) +4cos(x) / csc(x) -  3 - 2 √ 3 / csc(x) ]  . csc(x)  this is a product of two factors, 
[ 2√ 3 cos(x) +4cos(x) / csc(x) -  3 - 2 √ 3 / csc(x) ]  and csc(x) 

for more explanation

A(x) =[ 2√ 3 cos(x) - 3 + (4cos(x) - 2 √ 3 ) / csc(x)  ]  . csc(x)

ASAP PLEASE—-Mackenzie placed 5 pieces in the puzzle for bc every 4 pieces her little brother placed. If Mackenzie’s little brot
Alex_Xolod [135]

Answer:

45 pieces.

Step-by-step explanation:

First, if the ratio is 5 : 4, then is you multiply 4 x 5 to get 20, you need to multiply 5 x 5 to get 25.

Second, 20 + 25 = 45 which is the total amount of puzzle pieces.

Hope this helps!

What is there constant variation of y=kx through (5,8)
swat32

The value of constant of variation "k" is

Solution:

Given that the direct variation is:

y = kx ----- eqn 1

Where "k" is the constant of variation

Given that the point is (5, 8)

To find the value of "k" , substitute (x, y) = (5, 8) in eqn 1

Thus the value of constant of variation "k" is k = 8/5 or 1.6

I hope this is correct and helps!
