For this case we have a standard quadratic equation of the form:
 f (x) = ax ^ 2 + bx + c&#10;
 As the function is negative then the following is true:
 a \ \textless \ 1&#10;
 Therefore, when the leading coefficient is less than one then:
 1) The parable opens down.
 2) The cutting points with the x axis can be positive or negative
 3) The cutoff point with the y axis can be positive or negative
 4) The axis of symmetry can be to the right or to the left of zero.
 5) The vertex of the parabola is a maximum and this is because the second derivative is negative.

 Answer:
 
The vertex is a maximum.

Bharat and ingrid leave their building at the same time on their bikes and travel in opposite directions. If bharat's speed is 1
yanalaym [24]

Answer:

3 hours

Step-by-step explanation:

speed of Bharat = 12kilometers / hour

speed of Ingrid=14 kilometers / hour

For this problem we'll be using formula relating time, distance and speed.i.e

Distance = speed x time

Suppose Bharat is riding at a distance of 'b' kilometers, therefore time taken by him will be:

Time = distance/ speed

Time= b/12 hours.

Also, Ingrid can ride the distance at this time with speed of 14km/hr

The distance would be,

Distance = speed x time

Distance = 14 x (b/12) => 14b/12

Distance= 7b/6

Let 'd_{b}' be the distance that Bharat have covered after time 't'

therefore, d_{b} = 12 x t

Let 'd_{i} ' be the distance that Ingrid have covered after time 't'

therefore, d_{i} = 14 x t

In order to find the time when they are 78 kilometers apart, we will add d_{i}  and d_{b}, because they are travelling in opposite direction creating distance between them.

So,

d_{i} + d_{b} = 78

( 14 x t) + (12 x t) =78

14t + 12t =78

26t= 78

t= 78/26

t= 3hours.

thus, it will take 3 hours  until they are 78 kilometers apart
