Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
$450/week
30.5 hours/week
450/30.5 = $14.75
The answer is A (14.75/hour).
Answer:
C
Step-by-step explanation:
Let's check the first condition [y=110, t=0] for all the choices and eliminate:
A)
NO
B)
NO
C)
YES
D)
NO
E)
NO
Note: e^0 = 1
Only C is satisfied. But let's make sure the 2nd condition applies as well.
Hence, y approaches 30 as t goes to infinity. 2nd condition is satisfied as well.
Answer is C
Hey there,
Angle AEB + Angle CED = 180 degrees (vertically opposite angles)
(5x-10) degrees + (3x + 40) degrees = 180 degrees
5x -10 + 3x + 40 = 180 degrees
5x + 3x= 180 + 10 - 40
8x = 150
x = 150 / 8
= 18.75 degrees
Angle AEB = (18.75 x 5) - 10
=83.75 degrees.
Hope this helps ^_^
