Answer:
$30
Step-by-step explanation:
Divide the cost ($75) by the yards (2 1/2) to get $30 per yard.
Y = mx + b
plug in the numbers.
y = 4/3 + 2
Answer:
then subtitute x to find <FGH
Answer:
y" = csc(x)[9cot²(x) - csc²(x)]
Step-by-step explanation:
Step 1: Define
y = 9csc(x)
Step 2: Find 1st derivative
y' = -9csc(x)cot(x)
Step 3: Find 2nd derivative
y" = 9csc(x)cot(x)cot(x) + -csc(x)csc²(x)
y" = 9csc(x)cot²(x) - csc³(x)
y" = csc(x)[9cot²(x) - csc²(x)]
