Answer: A
Step-by-step explanation:
The main parent functions are x, and x raised to the power of something (examples:
, etc)
16/20 = 8(2)/10(2) = 8/10. 8/10 can also be further reduced to 4/5.
The tenth place is the first number to the right of a decimal. To determine if you're rounding or not, check the hundred's place, 2 numbers to the right of a decimal, for 5 or higher. If it's .45, round to .5, if it's .44, round to .4
Your answer is 524.5, which is B.)
-54-7r=10+25r
-7r-25r=10+54
-32r=64
r=64/-32
r=-2
Answer:

Step-by-step explanation:
The logistic function of population growth, that is, the solution of the differential equation is as follows:

We use this equation to find the value of r.
In this problem, we have that:

So we find the value of r.






Applying ln to both sides of the equality


So
The differential equation is
