F(x)=10e-0.02x this function represents the exponential decay of the bones of an extinct dinosaur in grams per year, where x is years. using the graph, how many years does it take for the bones to be less than 5 grams?

35 years

Step-by-step explanation:

We have been given an exponential decay function that models the weight of the bones of an extinct dinosaur;

The initial weight of the bones is;

substitute x with 0 in the function, f(0) = 10 grams

We are required to determine the number of years it will take for the bones to be less than 5 grams. The solution can be achieved either analytically or graphically. I obtained the graph of the function from desmos graphing tool as shown in the attachment below.

From the graph, the bones will weigh 5 grams after approximately 34.65 years. This implies that it will take 35 years for the bones to be less than 5 grams.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
