I was trying to figure out how tall this house was when i took a picture of it. I know I was 100 ft away from the house. I know the distance from the top of the house and where I took the picture was 150 ft. How tall is the house? Round to the nearest whole number.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.

the answer is  

d.

121π mi^2

hope you got it chief

if i knew id you bro,, my bad
