2. y=12000(.06)4x<span>
3. y=300(.08)5x
Hope this helps</span>
Simply multiply 4 for the terms in the parenthesis
4x-4
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
Please, see the attached file.
Answer: Third option 15.75 m
Learn this...it helps
HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number.
so ur equation y = -1....this is a horizontal line with a 0 slope
In slope intercept form it is : y = 0x - 1 <==....ur slope is 0 and ur y int is -1
The answer is probably the first or second one. I made it easier for you
