It holds 3.875 because 1 7/8 minus 5 3/4 is 3.875, or 3 7/8
Answer:
an = -39 -100(n -1)
Step-by-step explanation:
The given sequence can be described by a 3rd degree polynomial.* However, we suspect a typo, and that your intention is to have a formula for the arithmetic sequence ...
-39, -139, -239, -339
This has a first term a1 = -39, and a common difference d = -100.
The model for the explicit formula is ...
an = a1 +d(n -1)
Filling in the given values, the formula you seek is ...
an = -39 -100(n -1)
_____
* That polynomial is ...
an = 50n^3 +350n^2 -800n +461
This gives a sequence that starts ...
-39, -139, -139, -339, -1039, -2539, -5139, -9139, ...
Answer:
N/12 -10
Step-by-step explanation:
Because tan theta > 0 and cos theta is negative this angle is in the third quadrant.
angle whose cos is 2/5 is 66.42 degrees
The required angle is 180 + 66.42 = 246.42 degrees answer.
Initial number of quarters; 6
x = number of days
Number of quarters added after x days: 2x
Total amount of quarters, y = 2x + 6
Note: the slope is 2 and the y-intercept is 6.
