Hello, there! My name is Alice and I am here to help you today!

The answer is D)

Here are some notes that will help you with the whole lesson!

Earthquake: Sudden or violent shaking of the ground.

Epicenter: The point of the Earth's surface vertically above the focus of an Earthquake.

Focus: The focus is the place inside the Earth's crust where an earthquake originates.

Magnitude: The great size or extent of something.

Seismic wave: An elastic wave in the Earth.

Seismograph: An instrument that measures and records details of the Earthquake.

The Seismograph is used to find the Focus

Plate movement ⇒ Causes stress.

Stress ⇒ Increasing along faults.

Excess stress ⇒ Leads to rock breaking and an earthquake begins.

Earthquakes begin in the Lithosphere, usually 100km below the surface.

• Earthquakes have two centers

• The focus is the area beneath the surface where rocks beneath break under stress. It is the starting point of an Earthquake

• The Epicenter is the point on the surface directly above the focus

Earthquakes are caused by plate movement. And they begin at the focus.

• Waves carry energy as they travel

• The waves produced by an Earthquake are called Seismic waves

        Seismic waves are classified into three categories

                           « P waves (primary) »

• Arrive first, travel fastest

• Compressed and expand the ground like an accordion

• Travel threw solids and liquids

                      « S waves (secondary) »

• Arrive after P waves

• Vibrate from side to side and up and down

• Shake structures violently when they reach the surface

• Travel ONLY threw solids

                             « Surface waves »

• Travel ONLY on the surface

• Were P and S waves move

• Move slowly

• Can produce dramatic ground movement

• May make the ground roll

The Mercalli scale rates an earthquake according to how much damage it causes. And has 12 levels of intensity.

The Mercalli scale rates earthquakes based on the amount of damage they cause.

The Richter scale measures magnitude based on the size of seismic waves.

• Magnitude is determined by measures based on the size of seismic waves.

• Seismic waves are measured by a seismograph

• This scale is good for measuring small, nearby earthquakes

The moment magnitude scale estimates the total energy released by an earthquake.

• Useful for earthquakes of all sizes and distances

• Data collected with seismographs

• Shows what kind of waves were produced and their strength

The Moment of magnitude scale takes into account the movement of rocks along fault lines.

The Sumatra earthquake of 2004 is the third strongest earthquake ever recorded.

• Measured 9.1-9.3 on the Moment magnitude scale

• Measured at the maximum intensity on the Mercalli scale

• Lasted approximately 9 minutes, the longest duration ever measured

• Triggers a massive tsunami and killed  approximately 250,000 people

Geologists use Sisemic waves to locate an earthquake's Epicenter.

• Use Siesmograph  to measure the difference between the arrival of P and S waves

• Compare data to seismographs from around the world

Earthquakes are caused by stress along faults due to plate movement.

«Traveling Of Energy»

• Seismic waves travel in all directions

• Three types of waves:

• P waves (primary)

• S waves (secondary)

• Surface waves

«Measuring Earthquake   Energy»

• Mercalli scale

• Richter scale

• Moment magnitude scale

«Locating The Epicenter»

• Distance of epicenter measured from at least three seismographs

• Location of the epicenter is where three measurements overlap

Have a great day!

Answer:

x = 9

Step-by-step explanation:

Given:

m<1 = 8x

m<2 = (10x - 18)

Required:

Value of x

Solution:

<1 and <2 are alternate exterior angles. Alternate exterior angles are congruent. Therefore:

m<1 = m<2

8x = 10x - 18 (substitution)

Solve for x

8x - 10x = -18

-2x = -18

-2x/-2 = -18/-2

x = 9

Answer:

-14 F

Step-by-step explanation:

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

We see that our x-values span from -5 to 5. Since both are closed dots, they are included in the domain:

[-5, 5] or -5 ≤ x ≤ 5

Answer:

(f + g)(x) = x² + 2x - 6

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 1

g(x) = x² - 7

Step 2: Find (f + g)(x)

(f + g)(x) = 2x + 1 + x² - 7

(f + g)(x) = x² + 2x - 6

Answer:

B, Gina, $0.02

Step-by-step explanation:

Per pound is $1.38, so split it in half to get $0.69 for half a pound.

Then you have 1.38 + 1.38 + 0.68 = $3.45 total for Gina.

Per pound is $0.98, if you split that in half you get $0.49 for half a pound.

Add it up, 0.98 + 0.98 + 0.98 + 0.49 = $3.43.

You can see Gina spent more, and then you subtract 3.43 from 3.45 and get $0.02.

Answer:

10times

Step-by-step explanation:

there is a 50/50 chance of both 20 divided by 2 is 10

After tossing 20 times a coin probability of getting heads is equals to 10.

" Probability of any event is defined as the ratio of total number of favourable outcomes to the total number of outcomes."

Formula used

[tex]Probability =\frac{Number of favourable outcomes}{Total number of oucomes}[/tex]

According to the question,

Number of times coin tossed = 20

When we toss a coin there only two outcomes Head and Tail.

As per the formula,

Probability of head = 1 / 2

Probability of tail = 1 / 2

Therefore,

Probability of getting head when Karla tossed coin 20 times is equals to 20 / 2 = 10 times.

Hence, after tossing a coin 20 times  probability of getting heads is equals to 10 times.

  B.  {(0,2), (1,3), (4,3), (1,2)}

Step-by-step explanation:

A relation is not a function if the same input value maps to multiple output values. Essentially, if any x is repeated, it is not a function.

The second set, {(0,2), (1,3), (4,3), (1,2)}, has x-values of 0, 1, 4, 1, so 1 is repeated. It is not a function.

Step-by-step explanation:

Answer:

The measure of angle L is 52

Step-by-step explanation:

Mathematically, in a triangle, the sum of the angles equal 180

So in this case;

J + K + L = 180

So therefore;

8x + 6 + 2x + 2 + 4x + 4 = 180

8x + 2x + 4x + 6 + 2 + 4 = 180

14x + 12 = 180

14x = 180 -12

14x = 168

x = 168/14

x = 12

So to get the measure of angel L, we simply substitute the value x in the equation for L

From the question, L = 4x + 4

So therefore L = 4(12) + 4 = 48 + 4 = 52
