90% of 130 is 117 because 10% is 13 and 13x9 is 117 so that is part a. 130-117 is 13 so that is part b. And part c is correct because 100%-90%=10%. I hope this is helpful.

-1/2=3/2k+3/2<br> explain how you got your answer
meriva

-1/2=3/2k+3/2


Rewrite the equation to have k on left side


3/2k+3/2=-1/2


Simplify 3/2k


3k/2+3/2=12


Move all terms not containing k to right side


3k/2=1/2-3/2


3k/2=-2


Multiply both sifmdes by 2


2(3k/2)=-2(2)


3k=-4


Divide both sides by 3 to get k alone


3k/3=-4/3


K= -4/3

1.) The deer population increases at a rate of 3% per year. There are 1253 deer this year. Write a function that models the deer
BabaBlast [244]
Exponential growth/decay rule with general function is:<span>y=y(0)<span>e<span>kt</span></span></span> with k is growth/decay constant rate.
(1) Deer population function y(0) = 1253 k
= 3% t
 = 6 (years)
  y(6) = 1253 . e^(0.03*6) ~ 1500 (deers)
: 1496 deers
 (2) Growth factor b is rate 9.5% = 0.095
