Answer:
2,973
Step-by-step explanation:
The black bear population B(t), in the park is modeled by the following function:

Where t is the time(in years) elapsed since the beginning of the study.
We want to determine the black bear population in 25 years time, t=25.

There will be 2,973 black bears in 25 years time.
Tan x degrees = 31
To find X use arctan.
x = arctan(31)
x = 88.15
x = 88.2 (rounded to the nearest tenth)
Answer: 700.067 g
Step-by-step explanation:
Given : The pharmacist uses 67mg, 100g and 0.6 kg of drug to compound 3 separate prescription.
We know that 1 gram= 1000 milligram
and 1 kilogram = 1000 grams
Then, By UNITARY METHOD, 
Now, We convert each amount of drug into grams as ,

AND

Now, the total drug used by Pharmacist (in grams) = 
Hence, Pharmacist used 700.067 g of total drug.
