It is given that seismic activity d<span>ensity of a region is the ratio of the number of earthquakes during a given time span to the land area affected. so if the there 424 earthquakes and the land area is 71,300 sq miles.
seismic activity density = 424 / 71,300
</span>
<span>seismic activity density = 0.0059
the closest answer in the choices is 0.0056</span>
Answer:
The graph in the attached figure
Step-by-step explanation:
we have a exponential function of the form

where
y ---> is the population of bacteria
x ---> the number of hours
a is the initial value or y-intercept
b is the base of the exponential function
r is the rate of change
b=(1+r)
we have


so

substitute

For x=20 hours
substitute in the equation and solve for y

Answer:
x ≥ 1 (how to graph is listed below)
Step-by-step explanation:
To find where we need to plot the line, we first need to solve the inequality for x:
-2x - 3 ≤ -5
(Add three to both sides)
-2x ≤ -2
(Divide both sides by -2, but we can't forget that whenever we multiple or divide by a negative number, the sign flips!)
x ≥ 1
To graph this on the number line, you would put a dot on the 1 and fill it in completely (you fill in the dot for a "___ and equal to" sign. ex. ≥, ≤)
Then you would make an arrow from the dot to the right on the number line (this is because x must be greater than or equal to 1, so it must be facing in that direction)
