If you are about weather pressure, then on the site Studydaddy.com I found this information, there's a lot more on this subject and not only. Come and read)

Answer:

*In the tropics, the sun's rays fall almost flat on the earth's surface. Heated air rushes upwards, and an area of low atmospheric pressure forms at the surface, where there is a calm. There cooler air masses flow, creating at times only weak changeable winds. These movements of air masses determine the weather in the tropics. There, in the lowlands, the greenhouse climate dominates - it is hot and humid. Since at noon the sun is almost at the zenith, the heat reaches 30 ° and above. At night, the air is very little cooled, because there is high humidity. Early in the morning it's slightly easier to breathe, but soon there will be powerful cumulus clouds in the sky, often falling down in the downpour, which sometimes lasts all night.*

North and south of this belt, in the "horse latitudes", the cooled air descends to the surface, and there are regions with constant high pressure (anticyclone). The descending air masses in the form of a large spiral rotate in the Northern Hemisphere clockwise, and in the Southern hemisphere rotate against it. In these latitudes, clear windless weather is often established, in the daytime it is warm, at night it is cool. Other areas of anticyclones appear at the poles.

[1]: To query or describe the method via a task or series of tasks to complete a goal.

[2]: To query or describe an unknown quantity.

"How do I log on to Wiki"?

"How far is the sun from Earth"?

"To calculate how to cut the tree trunk, the surveyor had to measure how far the base was from the house then used trig to calculate the height using his theodolite".

that sounds like a problem about "slopes" so I am looking at using the derivative, which is basically the slope of the graph.

- the equation of line PQ can be simplified to y(x) = -2kx + k -8

- derivative relative to X (k is a constant) gives you -2k

- derivative of y(x) = 4x + 7 relative to x gives you 4

if the lines are parallel then the slopes are equal:

-2k=4 gives you k = -2 => your function becomes y = 4x - 8

if the lines are perpendicular the two slopes multiplied together give you -1:

-2k * 4 = -1 gives you k=1/8 => function becomes y = -1/4x - 7/8 or in other words y = -(2x+7)/8

I have made graphic representation and it looks to be correct.

I hope it makes sense.

f(x) + g(x) would just be the two functions added together.

f(x) + g(x) = 7x 2?4x+8 + (?6+4x?7x 2)

Sorry, I don't understand your initial functions.

Good luck.

q = x/(p^3) Substituting in 2 for p and 4 for q, we calculate x = 32 Now the formulas are q=32/p^3, or p=(cube root of 32/q)

to calculate your grade base on total points you have to know:

290 points represent the 100% so the question is how many percent is 232.17points.

x = (232.17x100) /290

x= 80%

and 80% is B-

Let's rewrite as

7(3x+5) = 8x -1(1-4x)

Let's distribute

21x + 35 = 8x -1 + 4x

collect like terms

21x + 35 = 12x -1

Put all the x's on one side by subtracting 12x from both sides

21x -12x + 35 = 12x -1 -12x

simplify

9x + 35 = -1

get all the constants on the right side

9x + 35 - 35 = -1 - 35

9x = -36

divide both sides by 9 to get x by itself

9x /9 = -36/9

x = -4

check in original equation

7(3(-4)+5) = 8(-4) -(1-4(-4))

7(-12+5) = -32 - (1+16)

7 (-7) = -32 - (17)

-49 = -32-17

-49 = -49

7(3x+5) = 8x -1(1-4x)

Let's distribute

21x + 35 = 8x -1 + 4x

collect like terms

21x + 35 = 12x -1

Put all the x's on one side by subtracting 12x from both sides

21x -12x + 35 = 12x -1 -12x

simplify

9x + 35 = -1

get all the constants on the right side

9x + 35 - 35 = -1 - 35

9x = -36

divide both sides by 9 to get x by itself

9x /9 = -36/9

x = -4

check in original equation

7(3(-4)+5) = 8(-4) -(1-4(-4))

7(-12+5) = -32 - (1+16)

7 (-7) = -32 - (17)

-49 = -32-17

-49 = -49

Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don't get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn't come up at all for months at a time.

Let's look at the overall picture. Does it make sense if you have a fifth of a pizza and add a half pizza, you get less than a third of a pizza.

Now, into the math.

Here is a fifth of a pizza.

Here is half a pizza.

It is hard to add these two.

We find the least common multiple of the denominators 2 and 5 and get 10.

Let's redo the pizzas in 10 slices.

And the half pizza.

Now with the same sized slices, we can add the slices and calculate the result.

Now we have seven slices out of ten, or 7/10.

Good luck.

Paul
