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)
<span>A. 23/93
If you wish to divide by a fraction then this is the same as multiplying by that fraction after you swap the numerator and denominator of that fraction. So (5/31) / (15/23) is the same as (5/31) x (23/15). When multiplying fractions you multiply the numerators by each other, and place them as the numerator of the answer and then multiply the denominators and that becomes the denominator of your answer. In this case you now have (5x23)/(31x15). You wish to reduce the fraction so you have (5x23)/(31x5x3) if you factor them. A 5 may be removed from both the top and bottom leaving you (23)/(31x3), or 23/93</span>
Answer:
8,050 yrds²
Step-by-step explanation:
The area of a rectangle is length × width, so 115 × 70 = 8,050 yrds²
