Answer:
The sequence is arithmetic with a common difference of -10
Step-by-step explanation:
From the question, we want to determine if the sequence is arithmetic or geometric
From the question
f(1) = 5
f(2) = -5
f(3) = -15
Mathematically for the common difference;
f(3) - f(2) = f(2) - f(1)
Since;
-15-(-5) = -5-5
-10 = -10
Since the common difference here is same , then the sequence is arithmetic with a common difference of -10
If you interpret the question as is, the answer is in the thousands which is not listed. The last part of the question should read “the number of new cases doubled from those newly identified cases from the day prior.” It was poorly phrased lol
Day 1: 5
Day 2: 5+10
Day 3: 15+20
Day 4: 35+40
Day 5: 75+80
Day 6: 155+160
Which is 315 at the end of the 6th day
1) the set of elements is,
10n where n belongs to {.....,-3,-2,-1,1,2,3....} (omitted 0).
And is the 2nd question complete?
Answer:

Step-by-step explanation:
If sketch of the circle and its points is shown as in the accompanying image, notice that the triangle formed FEC is an isosceles triangle, of which we know the angle at the center (angle ECF) to measure
.
Since the other two remaining angles must be equal to each other (they are <em>opposite</em> to sides of the same length - radii CE and CF of the circle), we have that the sum of all must render
