Step-by-step explanation:
Let be 
, 
. The decay rate per decay is deducted from the following relation:
Every decade, the number of species decays by a factor of 0.0834.
Use this formula
Revenue - cost = profit
Answer:
A - 5 square root of 3
Step-by-step explanation:
Take one of the triangles and use the pythagorean theorem. A^2 + B^2 = C^2
Hence,
5^2 + x^2 = 10^2
25 +x^2 = 100
25 +x^2 -25 = 100-25
x^2 = 75
Take the square root of both sides. . .
x = 5 square root of 3
