Answer:
CE = 12
Step-by-step explanation:
The triangles are similar triangle because they have base angles that are congruent (transversals of parallel lines) and their third angles are equal because they form vertical angles.
Since the triangles are similar, their side lengths are proportional to each other. Set up a proportion...
5/10 = x/8 (side with length of 5 corresponds to side with length of 10)
Now solve for x by cross multiplying
40 = 10x
4 = x
*They want the entire length of CE, so 8 + 4 = 12
Answer:The calculation is that from each of the point a chord can be connected to the 7 other points… and that makes 56 chords.
Step-by-step explanation:
It might be composite or prime
eg 21 is composite and 23 is prime.
Answer: B
Step-by-step explanation: How do we find the local extrema? Let f be continuous on an open interval (a,b) that contains a critical x-value. 1) If f'(x) > 0 for all x on (a,c) and f'(x)<0 for all x on (c,b), then f(c) is a local maximum value. 2) If f'(x) < 0 for all x on (a,c) and f'(x)>0 for all x on (c,b), then f(c) is a local maximum value.
Answer:
linear functions have no exponents higher than 1, and a graph that looks like a straight line. non-linear functions have at least one exponent higher than 1, and a graph that isn't a straight line.
I hope this helped :)
