if every short side is 1.5 in and every long side is 3 in what is the perimeter wilmart brainiest show your work
Zarrin [17]
Hello there (I can do this one, it's quick enough)

The correct answer is 24 inches

There are 8 short sides, so you would do 1.5 times 8, to get 12 inches

There are 4 long sides, so you would do 3 times 4, to get 12 inches

12 plus 12 = 24 inches

Simplify quantity 1 minus cosine squared theta divided by sine squared theta..
Ulleksa [173]
For this case we have the following fraction:
 (1-cos ^ 2 (θ)) / (sin ^ 2 (θ))
 We must take into account the following trigonometric identity:
 cos ^ 2 (θ) + sin ^ 2 (θ) = 1
 Therefore rewriting we have:
 sin ^ 2 (θ) = 1 - cos ^ 2 (θ)
 Substituting in the given fraction we have:
 (1-cos ^ 2 (θ)) / (sin ^ 2 (θ))
 = (sin ^ 2 (θ)) / (sin ^ 2 (θ))
 = 1

Why does the equation (x-4)^2-28=8 have two solutions?
Aliun [14]
<h3>Answer:</h3>

For your first answer it is because they are two different ways to solve the equation

<h3>Step-by-step explanation:</h3>

For Example!

<h2>Solution 1:</h2>

(x-4)² – 28 = 8The 8 is positive making it a different equation (this is like absolute value). (I am assuming you know the answer to the probelm)

<h2>Solution 2:</h2>

(x-4)² – 28 = -8

The 8 could be negative meaning that when you add the 28 to the right side it is -8+28 which will be a negative!

How do I find the value of WQ
Brut [27]

Answer:

WQ = 2.67 to the nearest hundredth.

Step-by-step explanation:

The area of triangle PQX = 1/2 * PX * QX.

The area of the rectangle = 8 * YX .

But YX = 2 PX  so its area = 8 *2PX = 16*PX.

We are given that area of PQX is 1/6 of the area of  WXYZ, so we have the equation:-

16 PX = 6* 1/2*PX * QX

16 = 3QX

QX = 16/3  = 5.33

Finally WQ = WX - QX

= 8 - 5.33

= 2.67
