Earthquake measuring 4.5 is 10 times more powerful than earthquake measuring 3.5 on Richter scale.
Step-by-step explanation:
Earthquake refers to the violent shaking of the Earth crust in response to its extremely dynamic interior. Sometimes the rocks are loaded or stressed beyond its elastic limit, following which it rebounds thus emitting a wave(seismic), which is received by us as seismic waves.
The energy released during an earthquake is measured in Richter scales (named after Charles Richter). While 1 is the lower limit, there is no such upper limit. However, earthquakes above 7 are considered fragile for human existence. It is a logarithmic scale meaning successive numbers of the scale by a factor of 10.
Thus, an earthquake measuring 4.5 would be around 10 times more powerful than an earthquake measuring 3.5 following logarithmic scale.
Answer:
Given statement: The number of gallons of water in the swimming pool x minutes after turning on the faucet is represented by :
.....[1]
The equation of straight line is represented by .....[2]
where
m represents the slope of line
and
b is the y-intercepts.
On comparing the equation [1] with [2] we get;
slope(m) = 24 and
y-intercept(b) = 285.
x-intercept defined as the graph crosses the x-axis i.e,
substitute the value of y =0 in [1] to solve for x;
0= 24x + 285
Subtract 285 from both sides we get;
-285 = 24x
Divide both sides by 24 we get;
x = -11.875
(a)
y= 24x + 285 where x is in minute.
You can see the graph of the equation as shown below.
(b)
Slope of the equation = 24
y-intercepts = 285
(c)
Since, x intercept is not applicable to this problem because value of x is negative as x represents the time(in minutes)
Answer:
This should be A. -4 < x < 9.
Step-by-step explanation:
Domains are the x-values. So, you would have to look at the x axis to know your x values. I'm not a 100% sure if this is that correct answer, but here's the answer to what I know.
I would agree with Mark6633 and go with 3
