Answer:
a = 1 and b = 2
Step-by-step explanation:
Using the Quotient Rule>
d/dx[(sin x)/(2+cos x) ]
= [(2 + cos x) * cosx - sin x * - sin x)] / (2 + cos x)^2
= 2cos x + cos^2x + sin ^2 x) / (2 + cos x)^2
But cos^2x + sin^2x = 1 so we have:
(1 + 2 cos x) / (2 + cos x)^2
- so a = 1 and b = 2.
The quadrilateral is a square
<h3>What are quadrilaterals?</h3>
Quadrilaterals are polygons, that have four sides and four corners
The coordinates are given as:
- A = (3, 5)
- B = (5, 2)
- C = (8, 4)
- D = (6, 7)
Start by calculating the adjacent side lengths using:

So, we have:




The side lengths are equal.
Hence, the quadrilateral is a square

If you add a constant to the original equation, you are actually shifting up or down
Since the constant is positive, you are shifting the graph 20 units up
