Answer:

n = 5 terms

Step-by-step explanation:

An = a1 + (n-1)d

9 = 3 + (n-1) 3/2

9 = 3 + 3/2n - 3/2

9 = 3/2 + 3/2n

9 - 3/2 = 3/2n

(15/2) / (3/2) = n

30/6 = n

Search to find the detailed rainfall collections if you want more detailed rainfall intensity data. If all available is monthly average in mm, take the monthly average and divide by number of hours in that month. So if you had 300 mm in April, take 360 mm/(30 days * 24 hours) = 0.5 mm/hour average monthly intensity. so that's it

Find the rate of change of the area of a square with respect
Romashka [77]
Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2

Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.

When z = 4, the rate is 4.
