I think it’s point A because -5 means it either a or b and 0.85 is closer to 6 so it’s point A

Answer:

Point A

Step-by-step explanation:

To find the values of each line on a number line. You find two points (e.g -6 and -5) and then you count how many lines there are in-between these points (in this case 10). So then you divide the difference in-between your two points (in this case -1) and divide it by however many lines there are (10). So 1/10 = 0.1/0.10. So each line on this number line are worth 0.1/0.10.

So to find -5.85 you can either go backwards from -6 or forward from -5. If you count up to -5.80 or down to -5.90, you'll then find Point A in-between both of these numbers. And as -5.85 is the mid point between -5.90 and -5.80, point A is the answer

Osama starts with a population of 1,000 amoebas that increases 30% in size every hour for a number of hours, h. The expression 1

Blizzard [7]

Answer: The correct option is A, itis the product of the initial population and the growth factor after h hours.

Explanation:

From the given information,

Initial population = 1000

Increasing rate or growth rate = 30% every hour.

No of population increase in every hour is,

$1000\times \frac{30}{100} =1000\times 0.3$

Total population after h hours is,

$1000(1+0.3)^h$

It is in the form of,

$P(t)=P_0(t)(1+r)^t$

Where $P_0(t)$ is the initial population, r is increasing rate, t is time and [tex(1+r)^t[/tex] is the growth factor after time t.

In the above equation 1000 is the initial population and $(1+0.3)^h$ is the growth factor after h hours. So the equation is product of of the initial population and the growth factor after h hours.
