Answer:
sin(-π/6) = -1/2
Step-by-step explanation:
sin(π/6) = 1/2 is a value we have memorized.
sin(-π/6) = -sin(π/6) = -1/2
You add 1/4. Because 19/4 is 4 3/4.
Answer:
x = 36
Step-by-step explanation:
To obtain the value of x, we must first obtain the value of y and z as shown in the attached photo.
i. Determination of y
2x + y = 180 (angle on a straight line)
Rearrange
y = 180 – 2x
ii. Determination of z.
z + 4x = 180 (angle on a straight line)
Rearrange
z = 180 – 4x
iii. Determination of x
x + y + z = 180 (sum of angles in a triangle)
But:
y = 180 – 2x
z = 180 – 4x
Therefore,
x + y + z = 180
x + 180 – 2x + 180 – 4x = 180
Collect like terms
x – 2x – 4x = 180 – 180 –180
– 5x = – 180
Divide both side by – 5
x = – 180 / – 5
x = 36
Therefore, the value of x is 36.
Assuming it declindes by 4% each time as in 4% of 1810 each time and not 4% of what it is now
1810*0.04=72.4
declindes at about 72.4 people per month
12 months per year
1810-(72.4*12)=941.2
so about 941 people 1 year after peak month
