Answer:
Choice A
Step-by-step explanation:
The scenario presented relates to exponential growth models; the population of bacteria is growing at an exponential rate given by the equation;
In this case B represents the population of the bacteria, t the time in minutes, k the growth constant and 1000 represents the initial population at time 0.
After 15 minutes, the population of bacteria grows to 8520. This implies that B is 8520 while t is 15. We substitute this values into the given equation and solve for k, the growth constant;
Divide both sides by 1000;
The next step is to introduce natural logs on both sides of the equation;
Answer:
2x^2
Step-by-step explanation:
because 2 is the greatest number that can go into them both equally and it can be squared evenly 2 x
Answer:
2xy
Step-by-step explanation:
first find each of their GCF
4&6=2
x^2&x=x
y&y^3=y
so GCF of 4x^2y&6xy^3=2xy
Answer:
y=1x+2
Step-by-step explanation:
the gradient is equal to 1 and the c in the question is 2 because the y-intercept represents c.
Gradient= (y2-y1)/(x2-x1)
