the inches of rainfall on mount waiale on Kauai in Hawaii is represented by the function f(x)=3^x+1-22 scientist are useing equations to study rain fall from year to year​.
Calculate how much rainfall there was in year four and In year nine. You must show all of your work and calculate.
Someone please help me answer this
f(4) = 3^5 -22
f(9) = 3^10 - 22
I suspect a typo, sine that's a LOT of rainfall. It triples every year.
What do you mean a typo? I typed the question as I was given. Not sure if just maybe you had it wrong
To calculate the rainfall in year four, we need to substitute the value of x = 4 into the function f(x) = 3^x + 1 - 22.
f(4) = 3^4 + 1 -22
= 81 + 1 - 22
= 82 - 22
= 60
Therefore, there was 60 inches of rainfall in year four.
Similarly, to calculate the rainfall in year nine, we substitute x = 9 into the function:
f(9) = 3^9 + 1 - 22
= 19683 + 1 - 22
= 19684 - 22
= 19662
Therefore, there was 19662 inches of rainfall in year nine.
