Step-by-step explanation:
tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
Answer:
-2,3
Step-by-step explanation:
x = -2
y = 3
..........
You are correct C. is the answer.
(2/3) / (1/9) = x / 1....2/3 day to 1/9 order = x days to 1 order
cross multiply
(1/9)(x) = (2/3)(1)
1/9x = 2/3
x = 2/3 * 9
x = 18/3
x = 6 days <==
