Answer:
1.30 hours
Step-by-step explanation:
Put the given number in the formula and do the arithmetic. The value of "d" is given as 7, so you are evaluating the expression ...
duration = 0.07×7^(3/2) . . . . put 7 where "d" is in the expression
= 0.07×18.520 . . . . . . . . . . . . evaluate 7^(3/2)
= 1.2964 . . . . . . . . . . . . . . . . . do the multiplication
≈ 1.30 . . . . rounded to hundredth
The duration of a storm 7 miles in diameter is predicted to be 1.30 hours.

If the sequence f is defined as
then
As you can see above, the difference between two consecutive terms gives us a constant.
So f is actually an arithmetic progression (AP), and it has (– 8) as its common difference:
• If f(1) = 100, then
