43 and 44, but it's closer to 43
Vertex at the origin and opening down → y=ax^2
Width: w=16
x=w/2→x=16/2→x=8
x=8, y=-16→y=ax^2→-16=a(8)^2→-16=a(64)→-16/64=a(64)/64→-1/4=a→a=-1/4
y=ax^2→y=-(1/4)x^2
7 m from the edge of the tunnel → x=w/2-7=8 m-7 m→x=1 m
x=1→y=-(1/4)x^2=-(1/4)(1)^2=-(1/4)(1)→y=-1/4
Vertical clearance: 16-1/4=16-0.25→Vertical clearance=15.75 m

Answer:
49/83 = m
Step-by-step explanation:
49=83m
Divide each side by 83
49/83 = 83m/83
49/83 = m
Answer:
B
Step-by-step explanation:
F(x) is just a negative vertical shift downwards, so when you have a downwards shift the number of units down is placed right after the x outside of the parenthesis. In this case, there was a shift of -4, so it would be -x^2 - 4.
