The exponential function will be written as:
y = 12 (0.56) ^ (t/4)
y=12 (0.56^ (1/4)) ^t
but
0.56^ (1/4) = 0.8651
thus plugging the value in y we get:
y=12 (0.8651) ^t
in two decimal places we get:
y=12 (0.87) ^t
Answer:
circumference of a circle: pi*d
d is also 2r (2 times the radius)
Independent variable = x(Cans of frozen OJ)
dependent variable = y(total cost)
