Max’s distance : Dave’s distance = 2 km : 5 km = 2:5
Max’s time : Dave’s time = 40 min : 15 min = 40:15 = 8:3
Answer:
(-5,-4)
Step-by-step explanation:
a_3 is 45 and a_10 is 98415
Step-by-step explanation:
Given
a_1 = 5
a_2 = 15
First of all we have to calculate the common ratio of the sequence. The common ratio is the ratio between two consecutive terms of a geometric sequence.
So,
The explicit formula for geometric sequence is:
Putting the value of r and a_1
Putting n=3 in the explicit formula
Putting n=10 for tenth term
Hence,
a_3 is 45 and a_10 is 98415
