Answer:
-0.38%
Step-by-step explanation:
Divide 31 by 50. 31 / 50 = 0.62.
1 - 0.62 = 0.38
Since it is a decrease in change the percent change is negative.
-0.38%

Answer:
m∠N = 85°
Step-by-step explanation:
<u>Properties of a parallelogram</u>
- opposite sides are parallel and equal in length
- opposite angles are equal
- interior angles that lie on the same side of the transversal are supplementary - their sum is 180°
Therefore,
m∠M + m∠N = 180°
⇒ 95° + m∠N = 180°
⇒ m∠N = 180° - 95°
⇒ m∠N = 85°
--------------------------------------------------------------------------------------
<u>Additional calculations</u>
m∠M = m∠P = 95°
m∠N = m∠L = 85°
MN = LP
ML = NP
-- The difference between the maximum and minimum values (9 minus -1) = 10
is double the amplitude of the sine wave, so its amplitude is 5 .
-- The distance in 'time' from the minimum to the maximum (3 minus -2) = 5
is 1/2 of the cycle, so the "wavelength" is 10 .
-- The sine 'begins' halfway between the minimum and maximum = at (1/2, 4) ,
and it's 'phase' is proportional to ' x/10 '.
The generic sinusoid is Y = A sin(2π x) .
We know that A = 5 . And this particular wave also has a constant of 4 added to it.
Now I just have to pick my way through the argument of the sine.
<u>Y = 4 + 5 sin [ 2π (x - 0.5)/10 ] .</u>
