Among various populations of plants or animals, diseases spread exponentially. Use the function y=325(1-e^-0.15t) to model the spread of potentially lethal Newcastle disease among a flock of 325 turkeys on a turkey farm, with t equal to the number of days since the first case of the disease. How many birds will be infected with Newcastle disease after 7 days?

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

y-y1=m(x-x1)

y-1=1(x-8)
