(f.g)(x) = f (g(x))= f ( x^4+3)
= (x^4+3)^2 + 2 ( x^4+3) - 6
= x^8 + 9 + 6x^4 + 2x^4 + 6-6
= x^8 + 8x^4+9
84 the process is shown in the following picture
Answer:
H = h + x
h = 568 meters
Step-by-step explanation:
The helicopter descends 114 meters to be 454 meters above the ground.
Therefore, the equation which describes this situation using h as the original height will be given by
H = h + x ....... (1)
Where H is the final height from the ground and x is the height that the helicopter ascends(Positive sign) or descends(Negative sign). (Answer)
Here, in our case, H = 454 meters and x = -114 meters.
Therefore, the original height of the helicopter from ground will be
h = H - x = 454 - (-114) = 568 meters. (Answer)
