Dr. silas studies a culture of bacteria under a microscope. the function b_1 (t)=1200〖(1.8)〗^t represents the number of bacteria t hours after dr. silas begins her study. what does the value 1200 represent in this situation? what does the value 1.8 represent in this situation? the number of bacteria in a second study is modeled by the function b_2 (t)=1000〖(1.8)〗^t. what does the value of 1000 represent in this situation and what does it tell you about the difference between the two studies?

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
