Answer:
Domain is: ( − ∞ , ∞ ) , { x | x ∈ R }
range is: ( − ∞ , − 3 ] , { y | y ≤ − 3 }
Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Step-by-step explanation:
a)
b) 1.5 hours after thickness will be 2 inches.
Angle EGF = 0.5(180° - 50°) = 65°.
Angle CGF = 180° - Angle EGF = 115°.
the answer is 7 because 7 *7 is 49
= 2+10²× 1
= 2+(10*10)× 1
= 2+100×1
= 2+100
=102
