Step-by-step explanation:
A circle have at max 360 degrees.




Answer:

Step-by-step explanation:
Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;
let;


Therefore;

Since x = cos y from the above substitute;

Hence,
gives the required proof
Answer:
(a) The minimum Edward would have to spend is $31.24
(b) The maximum Edward could spend is $33.34
Step-by-step explanation:
(a) Edward would spend a minimum of $31.24 if he gets either 10 zinnias, 8 pansies and 8 marigolds or 10 marigolds, 8 pansies and 8 zinnias.
(b) Edward could spend a maximum of $33.34 if he gets 10 pansies, 8 zinnias and 8 marigolds.
So my take on this
15 + 3 -2(2 - 1)
15 + 3 -2(1)
15 +3 -2
18 - 2 = 16
