Answer:
x = 0
Step-by-step explanation:
Given sin(3π/2+x) + sin(3π/2+x) = -2
2sin(3π/2+x) = -2
sin(3π/2+x) = -1
clearly x = 0 on satisfies the above equation
We know that sin(3π/2+x) = - cosx
-cosx = -1
cosx = 1 Has only one solution at x=0 in x∈ [0,2π)
Answer:
A
Step-by-step explanation:
Graph is not a function, so B and D are false.
y = 0 is a horizontal line, not a vertical line, so C is false.
This leaves only A.
Three hundred and eightteen and twentyfive meters
Answer:
if your solving for a its a=10b/9
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
complementary means add to 90
6x + 13 + 4x - 3 = 90
10x + 10 = 90
10x = 80
x = 8
