Answer:
588 square centimetres
Step-by-step explanation:
42*28/2=588
They left off the equation but we can know it's
y(t) = h₀ - g t² / 2
That's
y(t) = 144 - 16 t²
It hits the ground when
0 = 144 - 16 t²
16 t² = 144
t² = 144 / 16 = 9
t = 3 seconds
Answer: 3 seconds
Answer:
Step-by-step explanation:
The given function is,
The parent function of it is,
In graph y-axis is an asymptote (vertical) , so never crosses the y-axis. Hence no y intercept. And x intercept of is x=1.
The sign of x is changed in the given function as compared to its parent function
While reflecting over y axis or x=0 line, only the sign of x changes.
So graph of is the reflection of over y axis. Hence it has no y intercepts, x intercept at x= -1 and y-axis as asymptote (vertical).
