Answer:

1. Tectonic activity is responsible for some of Earth's most dramatic geologic events: earthquakes, volcanoes and deep ocean trenches can all be formed by tectonic activity in the lithosphere.

2.The lithosphere can affect the atmosphere when tectonic plates move and cause an eruption, where magma below spews up as lava above. This can also release copious amounts of volcanic ash or soot, which pollutes the atmosphere, blocks radiation and creates a cooling effect.

3. I don't know what's show on the text sorry that parts up to you good luck :)

The graph of the sine curve below is of electromagnetic energy that represents green light:
Gre4nikov [31]

Answer:

y=sin((pi/290)x)

Step-by-step explanation:

If we look at all the coordinates given (0,0),(145,1),(290,0),(435,-1),(580,0) we can draw it out and see what are our maximum and minimum y-value.  Once you graph this you will notice that the maximum y-value is 1 and minimum y-value is -1, this is important because we call this our amplitude.  Now we will determine our midline, we do so by getting the average of our amplitude so \frac{1+(-1)}{2}=\frac{0}{2} =0 and so our midline is zero.  Next we will determine our period in terms of radians we can do so by looking at our period which happens to be 580.  This means that the line will repeat itself every 580 on the numberline and so:

P=\frac{2\pi }{B}\\ \\580=\frac{2\pi}{B}\\\\B=\frac{2\pi}{580} \\\\B=\frac{\pi}{290}

Therefore our period in radians is pi/290.

A sine function is such that:

y=Asin(Bx)+D

where A is the amplitude, B is the period, and D is the midline.  Our amplitude is 1, midline is zero and our period is pi/290 and so our final equation is:

y=sin(\frac{\pi}{290}x)

Max has cashews that sell for $4.75 a pound and peanuts that sell for $2.75 a pound. How much must he mix to get 80 pounds of a
dolphi86 [110]

Answer:

10 lb of cashews and 70 lb of peanuts

Step-by-step explanation:

Let x = the pounds of cashews.

Then 80 – x = the pounds of peanuts

Value of cashews + value of peanuts = volume of mixture

x×4.75 + (80 – x)×2.75 = 80×3     Remove parentheses

   4.75x + 220 - 2.75x = 240        Combine like terms

               2.00x + 220 = 240        Subtract 220 from each side

                          2.00x = 20          Divide each side by 2.00

                                  x = 10 lb

                          80 - x = 80 – 10

                         80 - x = 70 lb

Max will mix 10 lb of cashews with 70 lb of peanuts.

=====

<em>Check: </em>

10×4.75 + 70×2.75 = 80×3.00

    47.50 + 192.50 = 240.00

                240.00 = 240.00
