The annual consumption of beef per person was about 64.9 lb in 2000 and about 60.7 lb in 2007. Assume B(t), the annual beef consumption t years after 2000, is decreasing according to the exponential decay model. a) Find the value of k, and write the equation. b) Estimate the consumption of beef in 2013. c) In what year (theoretically) will the consumption of beef be 30 lb?

Step-by-step explanation:

given that the annual consumption of beef per person was about 64.9 lb in 2000 and about 60.7 lb in 2007.

Assume B(t), the annual beef consumption t years after 2000, is decreasing according to the exponential decay model

i.e. , where t is the number of years from 2000

B0 = quantity in 2000 = 64.9

So the equation is

When t =7, B(7) = 60.7

Substitute to solve for k

So equation woul dbe

c) B(t) = 30 gives

i.e. in the year 2080

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.
