A quadratic function's graph being wide or narrow is determined or depended on a-term:
If |a| has a lot of value, for example a = 2 or a = 100. The graph will get narrower if increasing the value of |a|. On the other hand, If |a| has small value, for example a = 1/2 or a = 1/10000. The graph would be wide.
Also it does not matter if a-term is negative or not since a-term being positive or negative determines if a parabola is upward or downward. Only |a| determines how narrow/wide the graph is.
From the question, it is clear that the parabola y = 2x^2 is the narrowest graph since it has the highest |a| value out of all choices.
Answer
Roots test tells us to take the factors of the 20 divided by the factors of the coefficient of the the first.
factors of 20 are 1,2,4,5,10,20
factors of 1 are 1
so plus or minus 1/1, 2/1, 4/1, 5/1, 10/1, 20/1 are all possible rational zeros
Answer:
161.91
Step-by-step explanation:
First find the side length or YT by using the pythagorean theorem.
c= 129.2^2 = 16692.64
b= 68^2=4624
c-b = 12068.64
The square root of 12068.64 is approximately 109.86.
Using that length use the pythagorean theorem again and so:
a = 109.86^2 = 12068.64
c = 57^2 = 3249
a-c = 8819.64
The square root of 8819.64 is approximately 93.91.
So, 68 + 93.91 = 161.91
