I'm pretty sure it would be 50+15 because 5x3 is 15 and 5x10 is 50... correct me if I'm wrong
Answer:
7.25
Step-by-step explanation:
2 7/8 + 3 2/8 * 1 1/8 = 7.25
If b equals three
3 subtract 2
Equals one
Answer:
2
Step-by-step explanation:
So to figure this out we just need to flip the values of x and y in the table and then redefine that as the function g(x), because an inverse is essentially the reverse!
So if we flipped x and y's for f(x). We would see that our output or y of g(x) is -3 when x = 2, or in other words g(2) = -3. This means that we are now going to solve for when f(-3). So now lets look at the table and find the value at x = -3 for f(x). This value is 2, so the value of f(g(2)) = 2.
*In the future*
When you have a composite function of two inverses they essentially cancel out and would leave whatever the value of x is. So if we know f(x) and g(x) were inverses the value of f(g(2)) would just be 2.
For example:
ln(x) and e^x are inverses so if I had a composition like this:
The answer to this would be 2 because these inverse functions "'cancel" out
So
Answer:
Step-by-step explanation:
Maps are <em>drawn to scale</em>. This ensures that distances on the map are related to distances in the mapped area by a specific ratio. Measurements on the map can then be directly translated to measurements in the mapped area.
Maps are often <em>oriented</em>. Maps intended to be used outdoors are often oriented so that North is toward the top of the map. Carefully drawn maps for use indoors, such as evacuation route maps or mall store locators, are oriented so the direction you're facing when looking at the map is also the direction that is "up" on that map. That means locations that are shown as to the right of a give point on the map can be expected to be to the right of that point in the mapped area.

Over large areas of the Earth's surface different kinds of maps cope in different ways with the fact that the Earth is not flat. The best job is done by a globe, which matches the shape of the Earth. Flat maps make use of different kinds of projections, so that areas of more interest to the map-maker are better represented as to relative size and distance. (The scale necessarily varies from one part of the map to another.)
