While Sarah was driving into the one-way tunnel to Domainville, she saw that the tunnel had a shape that could be modelled by the quadratic equation ℎ(��) = −12��2 − 2�� + 16 ,
where ℎ is the height (in metres) of the tunnel and �� is the horizontal distance (in metres).
a) How wide is the tunnel at the road surface?

none.

step-by-step explanation:

m1=5

b

1

b=-1

find the slope and y-intercept of the second equation.

m2=0

b

b=-6

compare the slopes

m of the two equations.

m

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

are you missing something?
