The value of y when x=2 is 1.
Answer:
so the travled 20 miles upstream and altogether the travled 60 miles
Step-by-step explanation:
Answer:

Step-by-step explanation:
1) To find the 4th term given the Explicit Formula, i.e. definition, just plug it in. The common difference according to question is 4, the 1st term is 3.

2) For this another Sequence in Explicit definition we just need to plug it in:

The circle the has a center P(2,0) is bigger than compared to the circle with the center Q(0,4) because the former has a radius 20, while the latter has a radius of only 2. You can view the graph here:

(a) Describe the rule for translating center Q onto center P. By moving the center of circle Q overlapping the center of circle P, then we need to move it two units left and 4 units up.
(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P. In getting the scale factor, we need to compare the radius
= 2/10
= 1/10
So, the scale factor is 1/10
(c) Are circles P and Q similar? Explain your answer.
<span>Yes, by applying a dilation value, circle Q can be transformed to circle P, vice versa.</span>
