Answer:
- Mar 18: 125
- Mar 19: 318
- Mar 20: 743
- Mar 25: 15,070
Step-by-step explanation:
The six seemingly arbitrary points have no common difference or ratio, so cannot be modeled by a linear or exponential function.
The differences of the differences are not constant at any level, so the only polynomial model is 5th-degree. It is ...
(6n^5 -95n^4 +600n^3 -1825n^2 +2814n -1320)/60
where n = days after Mar 11. (Mar 12 corresponds to n=1.) The domain is n ≥ 1.
____
The 5th-degree polynomial increases very fast, but not as fast as an exponential function would.
The values for Mar 12 through Mar 25 are ...
3, 8, 11, 16, 25, 50, 125, 318, 743, 1572, 3047, 5492, 9325, 15070
The point (-1, 5) is located here:
Yes, I did draw that in paint just for you.
Answer:
x=25°
Step-by-step explanation:
The given angle is a 90° angle. We know this because of the little square in the corner. This means that both angles must add up to 90°:

Insert the known values:

Solve for x. Subtract 65 from both sides:

The missing angle, x°, is 25°.
