Answer:

Hurricanes, Sinkholes, Humans Impact, and Glaciers are contributory agents to the issues of coastal erosion.

Explanation

1) Hurricanes:

Sea levels can be rapidly elevated during a storm surge caused by hurricanes and extratropical storms. These spike in sea levels are directly related to severe erosion of shorelines which is estimated to cost about 3-5 billion US dollars annually.

2) Sinkholes:

in 2013, about 328 feet of the beach collapsed in Candelaria, Zambales over a  weekend creating an unsafe environment for residents and tourists. Their scientists suspected that it was due to a sinkhole. The collapse had deepened the shoreline by at least 1 meter.

3) Human Impact:

Sand mining from riverbeds and beaches, erection and construction of structures in coastal areas (like seawalls, jetties, breakwaters, etc), land reclamation along coastal fronts are all causes of coastal erosion.

In 2018, India reported massive erosion to its coastline. At that time, she had lost a whopping 33% of her shoreline over a space of 26 years. This is an average of 1.3% annually. Much of this loss was attributed to the increasing number of construction activities in such areas, damming of rivers (which prevented the rivers from carrying sediments to its coast which creates a balance), sand mining, and destruction of mangroves, etc.

4) Glaciers:

A Glacier is a moving body or river of ice that moves relatively slowly. It is formed by the gradual accumulation of compacted snow on mountains or near the poles. Glaciers have been known to move as fast as 30 meters per day. They can also be as slow as 0.5 meters per year. On average, you probably will record 25 centimeters of daily movement.

Combined with its gradual motion, the weight of a glacier could dramatically transform the terrain over a period spanning hundreds or even thousands of years. The weight of a glacier is very crushing. It is estimated at about 2 thousand tonnes.

As this huge weathering machine moves over land surfaces, expanding and contracting with weather fluctuations, the rocks underneath are disintegrated systematically into soil and shipped far from their points of origin.

The ice erodes the land surface and carries the broken rocks and soil debris far from their original places, resulting in some interesting glacial landforms.

Moving glaciers rip out of basins and create mountain valleys with sloping cliffs. Interesting historical examples of what Glaciers can do can be found in Scandinavia where it created fjords and deep inlets along its coast. It is also interesting to note that the shape of Cape Cod which looks like a  fishhook was carved by the snout of a glacier.

Answer:

B. (2,1)

Step-by-step explanation:

Substitute the first value from the parentheses for x, and the second value for y in the equation.

Calculate.

If the answer is true, the point is a solution on the line.

3(2) -5(1) = 1

6 –5 = 1

1 = 1. True. point B is a solution on the line.

D* for example:

3(2) -5(3) = 1

6 - 15 = 1

–9 = 1 False. This is not a solution on the line.

You get the idea. The others are also false.

Given:

The equation of a function is

[tex]y=(x-4)^2+1[/tex]

To find:

The graph of the given function.

Solution:

The vertex form of a parabola is

[tex]y=(x-h)^2+k[/tex]        ...(i)

Where, (h,k) is vertex of the parabola.

We have,

[tex]y=(x-4)^2+1[/tex]         ...(ii)

From (i) and (ii), we get

[tex]h=4, k=1[/tex]

The vertex of the parabola is (4,1).

Answer:

7/20 of the lawn still needs to be mowed.

The son mowed most of the lawn 7/20 of the lawn still needs to be mowed.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Mrs. jones mowed 2/5 of her lawn and her son mowed 1/4 of it.

Now, Size of the lawn mowed by Miss Jones = 1/4

And, Size of the lawn mowed by her son = 2/5

To know who mowed the most lawn, find the LCM of the denominators.

The LCM of 4 and 5 = 20

Make the denominators of both fractions to be 20

Hence, Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20

And, Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20

Since, 8/20 > 5/20, Miss Jones son mowed more part of the lawn than Miss Jones.

Hence, The part of the lawn still needs to be mowed is,

⇒ 1 - 1/4 - 2/5

⇒ 7/20

Answer:

The simplified expression is 6k+19 .

Step-by-step explanation:

Answer:

160

Step-by-step explanation:

First, lets assign a varible x. Let x be the number where 75% of x is 120. Next, we can convert the words of the problem into an equation. Now we have, 75% * x = 120 = 0.75x = 120. By multiplying both sides by 100, we get, 75x = 12000. So, x = 160.

Therefore, Options (2), (4) and (6) are the correct options.

Applying the negative exponent rule of power, the expressions that are equivalent to the given expression, 1/81, are: B, D, and F.

The negative exponent rule states that: [tex]a^{-n} = \frac{1}{a^n}[/tex].

Thus, given the expression, 1/81, it can be rewritten or simplified as follows:

1/81 = [tex]81^{-1} = 9^{-2}[/tex] = [tex]\frac{9^8}{9^{10}}[/tex] = [tex]9^5 \times 9^{-7}[/tex]

The expressions that will be equivalent to 1/81 can be expressed, based on the negative exponent rule of power, as:

[tex]9^{-2}, \frac{9^8}{9^{10}} , 9^5 \times 9^{-7}[/tex] (option B, D, and F).

Answer:

y = -5x + 8

Step-by-step explanation:

Slope-intercept form = ('y = x + b')

x being slope; b being the y-intercept.

Slope = rise/run (or y/x)

Take for example the point on the y-intercept, find the next intercepting point.

(0, 8); (1, 3)

In these points, y (rise/fall) decreases by 5. x increases by 1. Using rise/run (or y/x), we conclude that the slope is -5\1.

Answer:

I think y and z = 45
