Answer:
60 seconds
Step-by-step explanation:

When Ying reaches his lowest altitude, his velocity is 0.
The velocity, v(x) is the tiome-derivative of D(x).

(This was done by using chain rule)
Equating v(x) to 0,



Answer:
i gave you the slope and if its a function
Step-by-step explanation:
it a function
Slope (m) = ΔYΔX= 0
θ = arctan( ΔY )ΔX= 0°
ΔX = 10 – -2 = 12
ΔY = 3 – 3 = 0
Distance (d) = √ΔX2 + ΔY2 = √144 = 12
Equation of the line:
y = 0x + 3
When x=0, y = 3
Option B since -7/15 equals -0.4666...
Hope it helps!
