How do you know if two quantities vary directly?

Mathematics

Write an equation to model this situation. Then complete the input-output table below; and graph the equation on the coordinate plane provided. If two quantities x and y are directly proportional to one another, (meaning if x is doubled, so is y; if x is tripled, so is y), they show direct variation.

WHAT IS THE RELATIONSHIP BETWEEN THE ANGLE OF ELEVATION AND THE ANGLE OF DEPRESSION? GIVE AN EXAMPLE OF AN APPLICATION USING THE
Makovka662 [10]
Angles of Elevation and Depression are used in measuring heights and distances in trigonometric applications using right triangles. These angles are made when we look up or down to view objects. Devices are available to measure angles of elevation and depression. These measured angles can be used in measuring heights and distance which are either tedious or impractical to measure, by modelling the situation into right triangles

There is a square and a triangle
the area of a square is 
A = b * h 
A = 2*2
A = 4

the area of the triangle is 
A = (b*h)/2
A = (2 *2)/2
A = 4/2
A = 2

Now we add them up to find the total area
4 + 2 = 6
The shape has an area of 6 units^2

I really need help with these math problems!
Naya [18.7K]
A) 2.025 x 10^14 kilometers / 225 million years

B) 2.25 × 10^8

C) 2.025 x 10^14 kilometers / 2.25 x 10^8 years

D) 2.025 x 2.25 = .9

E) 10^14 - 8 = 10^6

F) .9 x 10^6

Notes:
To write in scientific notation, move the decimal place over until there is only 1 number outside of it. (25,000 now equals 2.5) Then count how many spaces you moved over (25,000 moved over three zeros, and the five. That is 4 places) that is what you use to put over the 10 (2.5 x 10^4 = 25,000)
