Some bullfrogs were introduced into a small pond. the graph shows the bullfrog population for the next few years. assume that the population grows exponentially.

equation: 140(315/140)^(t/2)
what is the growth rate?

50%

Step-by-step explanation:

The general exponential growth function is,

where,

y(t) is the function of time t, which represents the future amount,

a = initial amount,

r = growth rate in decimals,

The given function is,

Comparing this with the general function, we get the growth rate as 0.50 or 50%

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
