Answer:

Step-by-step explanation:

B.  Sale price  is (1.00 - 0.25)($7.79/yd) = 0.75($7.79/yd) =$5.84/yd, so the cost of 4 yd at this sale price is ($5.84/yd)(4 yd) = $23.36

A.  At regular price, the cost of 4 yds at $7.79/yd is $31.16.

What would be the solution to this Pythagorean/Trigonometric equation? (csc² A - 1) sen² A = cos² A
Anna007 [38]

Answer:

(csc^2 A -1) sin^2 A = cos^2 A

We know that csc x= \frac{1}{sin x} and using this identity we have:

\frac{sin^2 A}{sin^2 A} - sin^2 A = cos^2 A

1 = cos^2 A + sin^2 A

And if we remember the equation above represent the fundamental identity in trigonometry and is satisfied for every real number and we can say that the solution for this case is:

A= [X | x \in R]

Step-by-step explanation:

For this case we have the following equation given:

(csc^2 A -1) sin^2 A = cos^2 A

We know that csc x= \frac{1}{sin x} and using this identity we have:

\frac{sin^2 A}{sin^2 A} - sin^2 A = cos^2 A

1 = cos^2 A + sin^2 A

And if we remember the equation above represent the fundamental identity in trigonometry and is satisfied for every real number and we can say that the solution for this case is:

A= [X | x \in R]
