Answer:
1) 270 degrees
2) pi/4 rad
Step-by-step explanation:
1.) For which value of theta is sine theta = negative 1?
Given
sintheta = -1
theta = arcsin(-1)
theta = -90degrees
Since sin is negative in the third and 4th quadrant
In the third quadrant, theta = 180 + 90 = 270degrees
In the fourth quadrant, theta = 360 - 90 = 270 degrees
Hence the required value of theta is 270degrees
2) Given the radius of the circle to be 1, the y axis value will also be 1 units
Opposite = 1
adjacent = 1
hyp = √1²+1²
hyp = √2
sin theta = opp/hyp
sin theta = 1/√2
theta = arccsin(1/√2)
theta = 45 degrees
Express in radians
45 degrees = pi/4 radians
Hence the required angle in the first quadrant is pi/4 rad
I believe that your answer would be A. y < -294

Answer:
114
Step-by-step explanation:
The 5 angles equal 540, so subtract the 4 angles and you are left with 114.
540-111-103-122-90=114
Answer:
a)n = 24
b) 100 cm^3/s
Step-by-step explanation:
1/n = 2.5/60
n = 24
b) assuming you are not in calculus, the rate of the water will be constant k.
k = 4000/40 = 100 cm^3/s
