Answer:

1) 18 yards

2) x = 24

3) 36 yards

4) y = (-9/98)(x - 24)² + 18

Step-by-step explanation:

The path is symmetrical about x = h

h = (10+38)/2 = 24

x = 24

Distance = 18 + 18 = 36

Vertex: (24,18)

y = a(x - 24)² + 18

At t = 10, y = 0

0 = a(10 - 24)² + 18

a = -18/14²

a = -18/196 = -9/98

y = (-9/98)(x - 24)² + 18

1) The maximum height of the red bird in yards is; 18 yards

2) The axis of symmetry of the RED bird is; x = 24 yards

3) The total distance that the RED bird traveled in yards is; 28 yards

4) The equation for the RED bird's distance traveled in vertex form is; y = -⁹/₉₈(x - 24)² + 18

1) We are told that his flight reaches a maximum height of 18 yards.

Thus;

Maximum height of the red bird = 18 yards

2) He started his flight from the point (10, 0) and lands at a point (38, 0)

Axis of symmetry is symmetrical about the x-axis. Thus;

Axis of symmetry; x = (x₁ + x₂)/2

Axis of symmetry; x = (10 + 38)/2

Axis of symmetry; x = 24

3) The total horizontal distance will be gotten by subtracting the x-coordinate of the take off point from the landing point.

Total horizontal distance = 38 - 10

Total horizontal distance = 28 yards

4) The equation for the RED bird's distance travelled is gotten from the general vertex form;

y = a(x - h)² + p

where;

h is x-coordinate of vertex

p is y-coordinate of vertex

We know that max height of y = 18 is the y-coordinate of vertex while axis of symmetry, x = 24 is the x-coordinate of vertex.

Thus;

y = a(x - 24)² + 18

At the start point of (10, 0), we can find a

0 = a(10 - 24)² + 18

-18 = 196a

a = -18/196

a = -⁹/₉₈

Thus;

y = -⁹/₉₈(x - 24)² + 18
