Need help ASAP please!!! The formula determines the magnitude of an earthquake, where I is the intensity of the earthquake and S is the intensity of a “standard earthquake.” How many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6? Show your work.
Answer:
100
Step-by-step explanation:
M = log(I/S)
The intensity of the first earthquake:
8 = log(I₁/S)
10⁸ = I₁/S
I₁ = 10⁸ S
The intensity of the second earthquake:
6 = log(I₂/S)
10⁶ = I₂/S
I₂ = 10⁶ S
The ratio is:
I₁/I₂ = (10⁸ S) / (10⁶ S)
I₁/I₂ = 100
It is 100 times stronger.
An earthquake with a magnitude of 8 is 100 times stronger than an earthquake with a magnitude of 6.
Given the following data:
Magnitude A = 8Magnitude B = 6To determine how many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6:
Mathematically, the magnitude of an earthquake is given by the formula:
[tex]Magnitude = Log(\frac{I}{S} )[/tex]
Where:
I is the intensity of the earthquake.S is the intensity of a standard earthquake.For earthquake A:
[tex]8=Log (\frac{I_A}{S} )\\\\10^8=\frac{I_A}{S}\\\\I_A=S10^8[/tex]
For earthquake B:
[tex]6=Log (\frac{I_B}{S} )\\\\10^6=\frac{I_B}{S}\\\\I_B=S10^6[/tex]
For strength:
[tex]Strength = \frac{I_A}{I_B} \\\\Strength = \frac{S10^8}{S10^6} \\\\Strength = 10^2[/tex]
Strength = 100

Which one of the following lines is the graph of the
equation y = 2x - 3?
I'll give you brainliest!
Answer:
Line D
Step-by-step explanation:
The -3 is the y intercept, so the line must cross the y axis at -3.
The 2 is the slope. Slope is rise/run so the line needs to rise 2 for each run of 1 (up 2 right 1).
The only line that does both of these things is Line D.

Option D is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
y = cos x
Cos π = cos (π/2 + π/2) = Sin π/2 = 1
Cos 2π = Cos (π + π) = - Cos π = - Cos (π/2 + π/2) = - Sin π/2 = -1
We see that,
y = Cos x is strictly increasing from -1 to 1.
Thus,
y = cos x is strictly increasing from π < x < 2π.

Answer:
The smaller cup has a height of 4cm
Step-by-step explanation:
The two cups have a proportional relationship. This means that the since the smaller cup has a capacity that is half of the larger cup, the height will also be half of the larger cup height.

please help. find the measure of all missing angles.
Answer:
M1= 62 M2= 45 M3= 24
Step-by-step explanation:
For angle 1:
180-118 = 62
Angle 2:
180- (73+62)
Angle 3:
part 1
180-73= 107
part 2
180-(107+49)= 24
Answer:
Step-by-step explanation:
You have to solve for 1 before you do anything.
<1 + 118 = 180 The two left angles are supplementary
<1 +118-118=180-118
<1 = 62
Now you can go after angle 2
<1 + 73 + <2 = 180 All triangles have 180 degrees
62 + 73 + <2 = 180 Combine the left
135 + <2 = 180 Subtract 135 from both sides.
135-135+<2 = 180-135 Combine
<2 = 45
Angle 3 is a little trickier because the angle you need to find <3 is not labeled.
73 + x = 180
x = 180 - 73
x = 107
NOw you can find <3
107 + 49 + <3 = 180
156 + <3 = 180
<3 = 180 - 156
<3 = 24
I have left out the reasons for <3. Maybe you can supply them.

(-oo, 15)Oceanside bike rental shop charges 16 dollars plus 9 dollars an hour for renting a bike.Sam paid 52 dollars to rent a bike.How many hours did he pay to have the bike checked out?
Answer:
4 Hours
Step-by-step explanation:
Since the equation is:
y = 9x + 16
You have to find x
This is the logical way:
52-16 = 36 because thats the starting fee
So 36 divided by 9 equals 4
You do that because 9 is the charge per hr
So he rented it for 4 hours.

A high school is having a pancake breakfast fundraiser.They have 5 packages of pancake mix that each feed 140 people.The function N(p)=140p represents the number of people,N(P),that packages of pancake mix feed write the domain and range as compound inequalities.
Answer:
They have 5 packages of pancake mix.
N(p) = 140*p
Represents the number of people that can be feed with p = # of packages of pancake mix used.
Now, the domain will be the set of the possible values of p that we can use here.
the set of possible values of p will be:
{0, 1, 2, 3, 4, 5}
We can not use more than 5 because there are only 5 packages.
But we can use actually half a package or a third, so we not should use only whole numbers in the domain, then the domain can be written as:
D = 0 ≤ p ≤ 5
Now, the range is the set of the possible values of N(p)
The minimum will be when p = 0.
N(0) = 140*0 = 0
The maximum will be when p = 5
N(5) = 140*5 = 700
Then the range can be written as:
R = 0 ≤ N ≤ 700
Here we could add another restriction, because we can only feed a whole number of people, then we also should add the restriction that N must be a whole number:
R = 0 ≤ N ≤ 700, N ∈ Z
