Answer:
y = 0.48(x - 0.5)² - 3
y = 0.48(x² - x - 6)
Step-by-step explanation:
From the graph the zeros are
x = {-2, 3}
The x coordinate of the vertex is the midpoint of the roots
x = (-2 + 3) / 2
x = 0.5
The y coordinate of the vertex is
y = -3
vertex = (0.5, -3)
--------------------------------------
Merhod I - vertex
Vertex form is
y = a(x - h)² + k
plug in the vertex
y = a(x - 0.5)² - 3
to find a plug in either root
using x = 3
0 = a(3 - 0.5)² - 3
0 = a(2.5)² - 3
0 = 6.25a - 3
3 = 6.25a
a = 3/6.25
a = 0.48
y = 0.48(x - 0.5)² - 3
-----------------------------
Method II - roots
y = a(x + 2)(x - 3)
-3 = a(0.5 + 2)(0.5 - 3)
-3 = a(2.5)(-2.5)
-3 = -6.25a
3/6.25 = a
0.48 = a
y = 0.48(x + 2)(x - 3)
Expand
y = 0.48(x² - x - 6)
Answer:
For red: 18 in each row. For yellow: 6 in each row
Step-by-step explanation:
72 flowers/equal amount= 36 flowers each color 36/2 red (rows)=18 36/6=6 yellow
Answer:
61 km/s
Step-by-step explanation:
First, you count the number of hours he travelled: 22
Next, divide the distance he travelled, 1342, by the time he travelled, 22, 
Answer:
Well The answer is: 9
Step-by-step explanation:
(2 3/8 + 11/4)=
(2 + 3) + (3/8 + 3/4)= 6 1/8
(6 1/8 + 2 7/8) =
(6 + 2) + (1/8 + 7/8) = 9
Pls give me brainliest i hope this helped
