Answer: 45.1
Step-by-step explanation:
Answer:
Option A: f(x) = log_0.98 (n/74)
Step-by-step explanation:
We are told that that the number of species is decreasing by 2% per year.
Thus, number of species each year is 98% or 0.98 of number of species the previous year. .
We are told that there are currently 74 species of amphibians in the rain forest.
Thus, n/74 will represent a fraction of the current number of species.
Thus, the logarithmic function that models the time can be written as;
f(x) = log_0.98 (n/74)
Answer:4
Step-by-step explanation:
Answer:
x = 2.5
Step-by-step explanation:
- 2x + 14 + 10x = 34 , that is
8x + 14 = 34 ( subtract 14 from both sides )
8x = 20 ( divide both sides by 8 )
x = 2.5
Answer:
y=4x-1
Step-by-step explanation:
y2-y2/x2-x1
3--9/1--2=12/3=4
now the second part finding b
3=4(1)+b
3=4+b
-1=b
