The amount of carbon 14 present after t years is given by the exponential equation A(t) = Aoe^(kt), with k=-ln2/5600. A sample from a refuse deposit had 35% of the carbon 14 found in a contemporary living sample. How old was the sample?
(Round to the nearest hundred as needed.)

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
