The revenue of apple® went from $54.5 billion in 2013 to $74.6 billion in 2015. find an exponential function to model the revenue as a function of years since 2013. what is the continuous percent growth rate, per year, of revenue? round your answer to three decimal places.

74.6 - 54.5 = 20.1

20.1/2 = 10.05

54.5/74.6 = 0.731 (rounded)

Apple makes 10.05 billion more every year. The percent growth rate is about 73.1% a year.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
