5. To figure this out you must find when y = 0
-16t^2 = -200
t^2 = 12.5
Square root
t = 3.54 C
6.
Axis of symetry = -.5 (always a vertical line down vertex)
Vertex = (-.5, -6.5) (the minimum of the graph)
B
7. To find maximum height you must find the vertex
The maximum height is 549 feet after 5.75 seconds
C
9. Solve for X
x^2 = 1
Square root
X = plus or minus 1
A
X = 4 cm
the area of trapezium is
A = (4)(6) + (1/2)(4)(9-6)
A =30 cm^2
28/100 or 7/25
You can just add 100 as the denominator. <span />
Answer:
A=13.5 CM2
Step-by-step explanation:
A=BxH
A=4.5 cm x3 cm
A=13.5 cm2
