4. The number of houses in a town has been growing according to the recursive rule Pn=Pn-1 + 30, with initial population P0=200. a. Calculate P1 and P2 b. Find an explicit formula for Pn c. Use your formula to predict the number of houses in 10 years d. When will the number of houses reach 400 houses?

answer: options?

step-by-step explanation:

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
