Answer:
Step-by-step explanation:
The definition of a function f from A to B, regardless to injectivity or surjectivity, is that the domain of f is A, in its entirety.
This means that if f:A→B, then for every a∈A, there is a unique b∈B such that the pair (a,b)∈f.
So the converse holds just for it to be a function from A to B.
The decimals are equivalent to given expression are 50.020 and 50.02.

Answer:
Based on the results it is expected that the slope of the tangent line at the point (0.5,10) is -20.
Step-by-step explanation:
To see that compute, the slopes for the given points as follows:
1. For 
we have:
2. For 
we have:
3. For 
we have:
4. For 
we have:
So, we observe that the slope of the tangent line at 
is close to the value -20.
The graph shown below is useful to see the secant lines that approximates the tangent line.
Answer:
- triangles
- 180°
- triangles, 180°
Step-by-step explanation:
A diagonal divides a polygon into two parts. Drawing all of the diagonals from a given vertex to the other non-adjacent vertices will divide the polygon into triangles.
The angle sum theorem tells you the sum of triangle angles at any polygon vertex will be equal to the measure of the interior angle of the polygon at that vertex. Since we're concerned only with triangles created by drawing diagonals between non-adjacent polygon vertices, the sum of triangle angles will be the sum of polygon angles.
So, you can multiply the number of triangles by 180° to find the sum of interior angles of the polygon. (The number of triangles is two fewer than the number of polygon sides.)
