How many times larger is 9 x 10 to the power of -8 than 3 x 10 to the power of -12
Answer:
Second term=9
Third term=14
Twelfth term=59
Eightieth term=399
nth term=-1+5n
Step-by-step explanation:
First term=a=4
Common difference=d=5
using the formula
Tn=a + d x (n-1)
Second term=4 + 5 x (2-1)
Second term=4 + 5 x 1
Second term=4 + 5
Second term=9
3rd term=4+5x(3-1)
3rd term=4+5x2
3rd term=4+10
3rd term=14
12th term=4+5x(12-1)
12th term=4+5x11
12th term=4+55
12th term=59
80th term=4+5x(80-1)
80th term=4+5x79
80th term=4+395
80th term=399
nth term=4+5(n-1)
nth term=4+5n-5
nth term=4-5+5n
nth term=-1+5n
<h2>
Answer:</h2><h2>
The time taken to reach if we drive 50 miles per hour = 126 minutes = 2.1 hours</h2>
Step-by-step explanation:
The time taken to reach the location = 90 minutes = 1.5 hours
The speed driven = 70 miles per hour
By formula, speed = distance traveled / time taken
70 miles per hour = distance traveled / 1.5 hours
distance traveled in miles = 70 * 1.5 = 105 miles
Speed = 50 miles per hour
Distance = 105 miles
Time taken = ?
speed = distance traveled / time taken
50 = 105 / time taken
time taken in hours = 2.1 hours = 126 minutes
