Given: Cosine (x minus y) Equals sine left-brace StartFraction pi Over 2 EndFraction minus (x minus y) right-brace
Equals sine left-brace StartFraction pi Over 2 EndFraction minus x + y right-brace
Equals sine left-brace (StartFraction pi Over 2 EndFraction minus x) + y right-brace
Equals sine left-brace (StartFraction pi Over 2 EndFraction minus x) minus (negative y) right-brace
Equals sine (StartFraction pi Over x EndFraction minus x) cosine (negative y) minus cosine (StartFraction pi Over 2 EndFraction minus x) sine (negative y)
Equals cosine (x) cosine (negative y) minus sine (x) sine (negative y)
Equals cosine (X) cosine (y) + sine (x) sine (y)
Choose a justification for each step in the derivation of the sine difference identity.

Step 1:

Step 7:

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
