Research a minimum of 10 reusable/recyclable materials such as: empty soda bottles/cans, milk containers, water bottles, egg cartons, aluminum foil, paper (of any kind like paper towel rolls, magazines/catalogs, phone books, paper bags, cardboard boxes, newspaper, toilet paper, etc.), empty mail envelopes, glass containers, juice boxes, pie plates, styrofoam (such as restaurant take- out containers), plastic bags, etc. Things to report on should include the following: How long it takes to decompose in a landfill
How much of the material can be recycled
What materials it can be recycled into/what ways it can be reused – try to find two unique ways.
Part 2: Design Your Presentation

Design your presentation using Word, Power Point, Publisher, Prezi, Paint, or any other program you are familiar with.
Use at least one page/slide for each item your researched
Include images/graphics that show your items and how they can be used
Include a page/slide where you can give suggestions on how people can better recycle at work/home – try to include some unique or not so common ways
Have a References page/slide, listing all the sites you used in your research
Be Creative! You want to encourage people to recycle more.

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

compost can be added to topsoil as a:

pesticide

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
