The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.

The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:

speed = distance / time

Therefore,

distance = time × speed

distance = 15 × 65

distance = 975 miles

Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:

speed = distance / time

time = distance / speed

time = 975 / 50

time = 19.5 hours

The area of the triangle formed by points of intersection of parabola y=a(x-3)(x+2)
juin [17]

It is to be noted that the Area of the Triangle formed by the points of intersection of the Parabola derived from the equation y = a(x-3) (x+2) with the derived coordinates is 12.

<h3>What is a Parabola?</h3>

In mathematics, a parabola is a symmetrical open plane curve generated when a cone meets a plane parallel to its side.

Under the influence of gravity, a projectile's journey follows a curve of this shape.

Solution:

Step I - recall that y=a(x-3)(x+2)

This means that the base of the triangle is: 3-(-2) = 5

It's Height is = 6a. We arrive at this value when we make x = 0 and utilize the absolute value of the derivation.

Given that the area of a triangle is:

y=a(x-3)(x+2), we therefore have the following equation:

12 = 1/2 * 5 * 6 * A

If A = 4/5, then the solution to our equation comes to 12.
