The rocket that carried the Curiosity Rover to Mars traveled at a speed of 21000 miles per hour. What is this speed to the nearest mile per second?
Well, isn't that just fascinating? To find the speed in miles per second, we need to remember that there are 3600 seconds in an hour. So, when we divide 21,000 miles per hour by 3600 seconds, we find that the speed is approximately 5.83 miles per second. Isn't that just a delightful little calculation?
How do you find the nth term for this pattern- 10 20 40 80 160?
Oh, dude, finding the nth term for this pattern is like finding your favorite socks in the laundry - tedious but doable. So, to get from 10 to 20, you multiply by 2, then by 2 again to get 40, then 80, then 160. So, the pattern is just doubling each time. That means the nth term is 10 times 2 to the power of n-1. Easy peasy!
