Answer:
X = 0, π/2 in the interval [0, 2pi).
Step-by-step explanation:
Use the auxiliary angle method:
R sin(x + a) = Rsin x cos a + Rcos x sin a = 1
sin x + cos x = 1
Comparing coefficients:
R cos a = 1 and R sin a = 1, so
tan a = R sin a / R cos a = 1
So a = π/4 radians.
Also R^2(sin^2 a + cos^2 a) = 1^2 + 1^2 = 2
Therefore R = √2.
So √2 sin (x +π/4 = 1
sin x + π/4 = 1/√2
x + π/4 = π/4
x = 0 radians
Also
x = 0 + π/2 = π/2.
Answer:
I think the answer is 1a : 14b
Y = 4x + b
10 = -16 + b, b = 6
Y = 4x + 6
Y = 4(8) + 6, y = 38
The value of y is 38
So first we add the total pounds of harvested crop by the total number of hours:
48/24 which is 2
So 2 pounds of crop is harvested every hour, assuming that the working is constant throughout all four workers.
So:
Employee -
A: 12 pounds
B: 8 pounds
C: 12 pounds
D: 16 pounds
