Answer:
See below
Step-by-step explanation:
Remember the quotient identity
, so you need to take the reciprocal of the sine value for the given angle in order to get the cosecant value for that same angle.
Answer: There are 43 white marbles.
Step-by-step explanation:
t = total number of marbles = 54
w = white marbles = 4b - 1
b = blue marbles
54 = b + (4b - 1)
b + 4b = 5b
54 = 5b - 1
+1
55 = 5b
/5
11 = b
There are 11 blue marbles.
4(11) - 1
44 - 1 = 43
43 + 11 = 54, therefore our solutions are correct.
Point-Slope Equation: y - y₁ = m(x - x₁) ; where (x₁, y₁) is the point and m is the slope
(x₁, y₁) = (4, 1700) and m = 200
y - 1700 = 200(x - 4)
