This is the graph, the x and y intercept would be (0,0)
Answer:
Step-by-step explanation:
Answer: A. scalene
<u>Step-by-step explanation:</u>
scalene = all three sides have different lengths
isosceles = two of the sides have the same length
equilateral = all three sides have the same length
AE = 5 <em>(2.5 + 2.5)</em>
ED = 3
AD = 7
Since all three sides have different lengths, it is a scalene triangle.
********************************************************************************
If it is a right triangle, then 3² + 5² = 7²
9 + 25 = 49
34 ≠ 49 <em>so it is not a right triangle</em>
Given the number of contestant in each round:
X 1 2 3 4 5
F(x) 243 81 27 9 3
Rate of change can be calculated using y2-y1/x2-x1 formula. From
rounds 1 to 4 the rate of change are
-162, -54, -18. And the average of it is -78 and it
represents the average rate at which the number of contestants changed from the
first round to the fourth round.
