From the table we notice that:
This means that Diana traveled 11595 ft more than martin; this also means that Jake and Abby traveled more than that amount farther than Martin's balloon (since their distances are greater that Diana's distance)
Therefore, Abby's Jake's and Diana's balloons traveled 11595 ft farther than Martin's balloons.
Answer:
The equation of the axis of symmetry is x =
The coordinates of the vertex are ( , ) ⇒ 2nd answer
Step-by-step explanation:
The quadratic function y = ax² + bx + c is represented graphically by a parabola which has a minimum/maximum vertex (h , k), where
- h = and k is value y at x = h
- The axis of symmetry of the parabola is a vertical line passes through the vertex point and its equation is x = h
- The minimum/maximum value of the function is (h , k)
∵ y = 4x² + 5x - 1
∵ The form of the quadratic function is y = ax² + bx + c
∴ a = 4 , b = 5 , c = -1
∵ The coordinates of the vertex points are (h , k)
∵ h =
∴ h =
- To find k substitute x in the function by
∵ k = 4 ( )² + 5( ) - 1
∴ k = 4 ( ) + ( ) - 1
∴ k = - - 1
∴ k =
∴ The coordinates of the vertex are ( , )
∵ The equation of the axis of symmetry is x = h
∵ h =
∴ The equation of the axis of symmetry is x =
