Apopulation of 510,000 toads is expected to shrink at a rate of 6.2% per year. which is the best prediction for the toad population in 18 years?
a. 478,380
b. 316,200
c. 161,147
d. 86,108

 c. 161,147

Step-by-step explanation:

The exponential decay function with rate of decay r in x years is given by :-

, where A is the initial population.

Given : Initial population of toads= 510,000

The rate of decay = 6.2%= 0.062

The population of toads after 18 years is given by :-

Hence, the best prediction for the toad population in 18 years is 161,147.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
