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
Answer: -43/20
Step-by-step explanation: you just need a college calculator to solve ,you need to just plug the numbers and it will do it for you.
Si, es cierto. Si, es cierto.
Answer:
No, because he has a sum of 0.
Step-by-step explanation:
3+11-5-8-2+1
=14-5-8-2+1
=9-8-2+1
=1-2+1
=-1+1
=0
Answer:
Example
Step-by-step explanation:
1 Determine if the value 3 is a solution of the equation .Notice in the equation 3x + 3 = x + 13, the solution 5 is not evident by . 2x-2x + 9 = 3x- 9-2x+ 9. 9 = x. from which the solution 9 is obvious. If we wish, we .
