In 1995, an earthquake in Mexico registered 8.0 on the Richter scale. In 2001 , an earthquake of magnitude 6.8 shook Washington state. How many times more intense was the 1995 earthquake than the 2001 earthquake?
The earthquake in 1995 was 1.2 times than the 2001 earthquake .
In 1935, American geologist Charles Richter (1900-1984) predicted the magnitude M of an earthquake is given by [tex]M=log(\frac{I}{S} )[/tex] where 'I' is the intensity of the earthquake (measured by the amplitude of the seismometer 100 km from the epicenter), 'S' is the "standard" seismic intensity whose (amplitude is 1 micron = 10 -4 cm). Standard earthquake magnitude is 0.
It is given that in 1995, an earthquake in Mexico registered 8.0 on the Richter scale and earthquake of magnitude 6.8 in Washington state.
If [tex]I_1[/tex]and [tex]I_2[/tex] are the intensities of the Mexico and Washington earthquakes, then we are required to find [tex]\frac{I_1}{I_2}[/tex]. To relate this to the definition of magnitude, we divide numerator and denominator by S
[tex]log(\frac{I_1}{I_2})=log\frac{\frac{I_1}{S} }{\frac{I_2}{S} }[/tex]
Using property of logarithm [tex]log\frac{a}{b} =loga-logb[/tex] , we get
[tex]log(\frac{I_1}{I_2})=log{\frac{I_1}{S} -log{\frac{I_2}{S} \\\\\\[/tex]

2. The translation (x, y) → (x + 3, y-7) maps TUVW onto T'U'V'W'. What translation maps
TU'V'W' onto TUVW?
O(x,y) → (x+3, y-7)
O(x,y) → (x-7, y + 3)
O(x,y) → (x+7,y-3)
O(x,y) → (x-3, y+7)
The mapping of T'U'V'W' onto TUVW is translated as follows:
(x, y) → (x - 3, y + 3)The translation:The backward translation of the mapping T'U'V'W' onto TUVW is the mapping TUVW onto TUVW.
The coordinates of the -axis move by units in the right direction during the translation (x, y) → (x - 3, y + 3), while the coordinates of the y-axis move by 3 units downward.Therefore, we must return to our original position for the mapping of T'U'V'W' onto TUVW.Reversing the mapping involves the steps listed below.
As was previously mentioned, moving all x-coordinates by 3 units in the right direction is the opposite of moving them in the opposite direction. As a result, x-3 would be the translation for the x-axis.Earlier, all y-coordinates were moved by 3 units downward; the inverse of this is an upward 3 unit move for all y-coordinates. As a result, y+3 would be the translation for the x-axis.Therefore, the mapping of T'U'V'W' onto TUVW is translated as follows:

[tex]y = 5x \stackrel{\stackrel{b}{\downarrow }}{+2} \qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\qquad \implies \stackrel{y-intercept}{(0~~,~~2)}[/tex]
so we're really looking for the equation of a line that passes through (2 , -3) and (0 , 2)
[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{-3})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{2}-\stackrel{y1}{(-3)}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{2}}} \implies \cfrac{2 +3}{-2} \implies -\cfrac{ 5 }{ 2 }[/tex]

The loudness in decibels dB of a sound is defined as 10 log I/I₀ , where I is the intensity of the sound in watts per square meter (W / m²) . I₀ , the intensity of a barely audible sound, is equal to 10⁻¹²W/m². Town regulations require the loudness of construction work not to exceed 100 dB . Suppose a construction team is blasting rock for a roadway. One explosion has an intensity of 1.65x10²W/m² . Is this explosion in violation of town regulations?
a. Which physical value do you need to calculate to answer the question?
a) The explosion does violate the town regulation
b) The two physical quantities are the I(intensity of the sound) and
[tex]I_{o}[/tex] (detectable intensity)
The values that we have been given are
L = loudness of the sound = 10 log(I/[tex]I_{o}[/tex])
I = intensity of the sound in watts per square meter = [tex]1.65 * 10^{2} W/m^{2}[/tex]
[tex]I_{o}[/tex] = intensity of barely audible sound = [tex]10^{-12} W/m^{2}[/tex]
Putting the required value in the equation of the loudness we get
a) L = [tex]10 log(\frac{1.65*10^{2} }{10^{-12} } )\\[/tex]
L = 10 * 14.217 dB = 142.17 dB
And according to the town regulation the loudness of the construction work should not exceed 100dB.
Thus the explosion is in violation of the town regulation as it exceeds 100dB.
b) the two physical value we have to calculate are I which is intensity of the sound in watts per square meter and [tex]I_{o}[/tex] which is intensity of barely audible sound. The respective values are
I = intensity of the sound in watts per square meter = [tex]1.65 * 10^{2} W/m^{2}[/tex]
[tex]I_{o}[/tex] = intensity of barely audible sound = [tex]10^{-12} W/m^{2}[/tex]

A spherical water tank holds 9000 ft³ of water. What is the diameter of the tank? (Hint: (¹/₆ d³ π=V)
The diameter of the tank is 25.8 feet.
We are given the volume of water tank. Also, we are provided the formula relating volume and density.
Rewriting the formula -
V = 1/6×π×d³, where d represents the diameter. Taking the value of π as 3.14
Rewriting the formula according to diameter -
d³ = 6V/π
Keep the values in formula to find the value of diameter of water tank
d³ = 6×9000/3.14
Performing multiplication and division to find the value of diameter
d³ = 54000/3.14
Performing division to find the value of diameter of water tank
d³ = 17197.45
d = ∛17197.45
Taking square root to find the value of diameter of water tank
d = 25.8 feet
Hence, the diameter of tank is 25.8 feet.

How to Interpret the Y-intercept of a Line?The y-intercept is the value of the y-coordinate of the point where the line intercepts the y-axis.
The y-intercept is referred to as the starting value or initial value. At this point, x = 0.
1. First, find the slope (m) of the line using two points, (1, 18) and (2, 24):
Slope (m) = change in y/change in x = (24 - 18)/(2 - 1) = 6/1
Slope (m) = 6
Substitute m = 6 and (x, y) = (1, 18) into y = mx + b to find the y-intercept, b:
18 = 6(1) + b
18 - 6 = b
b = 12 (y-intercept)
Substitute m = 6 and b = 12 into y = mx + b:
y = 6x + 12
The y-intercept that connects all the data points is: 12.
2. The y-intercept in this context represents the initial cost that excludes the charge for each DVD.
3. Substitute x = 12 into y = 6x + 12 and solve to see if y equals 90:
y = 6(12) + 12
y = 84 [not equal to $90)]
Thus, your friend is incorrect. a dozen DVD's can be gotten for $84.
4. Substitute x = 50 into y = 6x + 12:
y = 6(50) + 12
y = 312

What is volume of cylinder?
Volume of cylinder is calculated as;
v = π r² h
Since, Container A has a diameter of 18 feet and a height of 9 feet.
Then, Radius = 18/2 = 9 ft
Hence, Volume of Container A = π r² h
= 3.1416 * 9 * 9 * 9
= 2,290.22 ft³
Since, Container B has a diameter of 16 feet and a height of 11 feet.
Then, Radius = 16/2 = 8 ft
Hence, Volume of Container B = π r² h
= 3.1416 * 8 * 8 * 11
= 2,211.68 ft³
After pumping all of container A into container B there will remain empty space in B = 2,290.22 - 2,211.68 = 78.5 ft³
And, The percentage for this empty space is of the entire volume is,
78.5/2,290.22 = 0.03427 *100 = 3.4 %

The value of x in the equation x² - 2 x + 5 = 2 is 1 ± i √2.
We are given the equation:
x² - 2 x + 5 = 2
We need to solve the equation to find the value of x.
For this, we will first subtract 2 from both the sides:
x² - 2 x + 5 - 2 = 2 - 2
x² - 2 x + 3 = 0
Now, we will solve for the value of x:
D = b² - 4 ac
D = (- 2)² - 4 (3)(1)
D = 4 - 12
D = - 8
√D = 2 i √2
Now putting it in quadratic formula, we get that:
x = (- b ± √D) / 2 a
x = (2 ± 2 i √2) / 2 (1)
x = 1 ± i √2
Therefore, the value of x in the equation x² - 2 x + 5 = 2 is 1 ± i √2.
