In a study by the Texas A & M University, found there were 23,000 prairie dogs in Texas in 2000. By 2010, the number has inc
reased to 40,000. The exponential growth function D=2.3e^kt describes the prairie dog population, D in ten thousands, t years after 2000. A) solve for k
B)by this model how many prairie dogs existed last year?
C)in which year will the population double?
PLEASE HELP!
First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1
