Answer:
Marco- 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent.
Isabella- 1 is the starting population. 1+0.2=1.2 is the rate at which it grows each day.
Step-by-step explanation:
Marco's equation should be
since the bacteria double each day. 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent. This will double each day because:
Day 1 is 
Day 2 is 
Day 3 is 
Day 4 is 
You'll notice the value doubles each day.
Isabella has a different equation because her population increases by a percentage. We use the simple interest formula to calculate the bacteria's daily increase or interest.
1(1+0.2)d
1 is the starting population.
1+0.2=1.2 is the rate at which it grows each day.
For the first problem, the answer is D, because every year, the graph goes down by about $4,500.
For problem two,
a. It's located in quadrant one because x and y are both positive (I've attached a graph with labeled quadrants for reference)
I'm unsure about b and c but I hope I helped with the others!
For what value of B is the trigonometric function considered an odd function? y=cosB(x-c)
1/4
Step-by-step explanation:
Question number 1 The part is 23 and the whole is 35 and the percent is 66%.
Question number 2 is The part is 20 and the whole is 32 and the percent is 62.5%.
Question number 3 is 41 is 82% of 50.
Question number 4 is 3 is 6%of 18.
Question number 5 is 14 is 28% of 50.
