48 mph
The rate in miles per second can be converted to the rate in miles per hour by multiplying by the number of seconds in an hour:
Answer:
7.994×10^3
3.99780×10^5
1.0051×10^4
3.5×10^1
3.5094013×10^7
209.095.543and 8 tenths
(3/2)x - 2 < 7
(3/2)x < 9
3x < 18
x < 6
answer is b
The first differences are 8, 14, 20.
The second differences are 6.
Half of 6 is 3, so the first term of the sequence is 3n^2.
If you subtract 3n^2 from the sequence you get 0,-1,-2,-3 which has the nth term of -n + 1.
Therefore your final answer will be 3n^2 - n + 1
