Answer:
32 dollars.
Step-by-step explanation:
If the sol'ns are -9 and 9, then we can use this to form our eq'n:
(x - 9)(x + 9) = 0
x^2 - 81 = 0
so...
x^2 + z - 103 = x^2 -81
z - 103 = -81
z = -81 + 103
z = 22
Answer:
B. 2 seconds, 5 seconds
Step-by-step explanation:
Looking at the graph, you can see that the vertex, or the point where the graph is at it's highest point, is at 2 seconds and a little over 2 meters in height.
