Answer:
- geometric sequence with initial value 20 and common ratio 1/2
- average rate of change on [1, 3] = -7.5
Step-by-step explanation:
(a) The given points have sequential values of x and values of y that are each 1/2 the value before. The common ratio tells us the sequence is a geometric sequence.
(b) The first given point is (2, 10), so extrapolating backward, we determine the previous point to be ...
... (2-1, 10/(1/2)) = (1, 20)
Thus, we have enough information to determine the average slope between n=1 and n=3.
... (difference in y)/(difference in n) = (5 -20)/(3 -1) = -15/2 = -7.5
Answer:
3
Step-by-step explanation:
Since
3 : 2 = X : 2
Then we know
3/2 = X/2
Multiplying both sides by 2 cancels on the right
2 × (3/2) = (X/2) × 2
2 × (3/2) = X
Then solving for X
X = 2 × (3/2)
X = 3
Therefore
3 : 2 = 3 : 2
Step-by-step explanation:
The answer is
X=23
