Answer:
6 + 4x − x² = 10 − (x − 2)²
the turning point : (2 , 10)
Step-by-step explanation:
6 + 4x − x² = − x² + 4x + 6
= − (x² − 4x) + 6
= − (x² − 4x + 4 − 4) + 6
= − [(x − 2)² − 4] + 6
= − (x − 2)² + 4 + 6
= − (x − 2)² + 10
= 10 − (x − 2)²
Then the turning point of y is (2 , 10)
A) 3, 5, 6
c squared = a squared + b squared
6 squared = 5 squared + 3 squared
36 = 25 + 9
36 ≠ 34 (not a right triangle)
b) 13, 12, 5
c squared = a squared + b squared
13 squared = 12 squared + 5 squared
169 = 144 + 25
169 = 169 (is a right triangle)
c) 17, 15, 9
c squared = a squared + b squared
17 squared = 15 squared + 9 squared
289 = 225 + 81
289 ≠ 306 (not a right triangle)
d) 12, 8, 6
c squared = a squared + b squared
12 squared = 8 squared + 6 squared
144 = 64 + 36
144 ≠ 100 (not a right triangle)
hope this helps!!
Answer:
1.52380952381 is the correct ans
It cannot because it is almost a perfect correlation, and its not a high enough correlation.
