Answer:
turning point: (-3 , -16)
Step-by-step explanation:
y = x² + ax + b pass(0,-7)(7,0)
(0)² + 0*a + b = -7 b= -7
(7)² + 7*a - 7 = 0 7a = 42 a = 6
y = x² + ax + b = y = x² + 6x - 7 = (x+3)² - 16
(h,k): vertex equation: y = a(x-h)² + k
h = -3 k=-16
So half of 3.1 is 1.05, so if you add the 4 to 1.05, you get 5.05, or 5005 metres- which is how far Tony’s ran
The answer should be .4 X cubed +1300 X squared -300+50
Answer:
In component form, vector GH is <4, -5>.
Step-by-step explanation:
The head end of the vector (H, the one with the arrow) is 4 units to the right and 5 units below the tail (G).
The components are listed horizontal first, then vertical. The value of the component is the number of (unit) grid squares. Positive is up or to the right, as in the x-y coordinate plane. So, this vector is <4, -5>.
