Leonardo decided to start training to run in a marathon to keep in shape. After 5 training sessions, he had run a total of 25 mi
lisov135 [29]
Total distance ran by Leonardo in 5 training sessions = 25 miles
Then
Total distance ran by Leonardo in 1 training session = (25/5) miles
                                                                                   = 5 miles
Total distance ran by Leonardo today was half the distance he actually covers in every training session.
So
Total distance ran by Leonardo today = (5/2) miles
                                                             = 2.5 miles
So Leonardo ran for a distance of 2.5 miles today. <span>It is actually very important to read the question carefully and then the answering the question becomes easy.

Explain how you could write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two dis
KATRIN_1 [288]
The vertex is on the axis of symmetry, so the axis of symmetry is x = 3. Find any two x-intercepts that have the equivalent distance from the axis of symmetry. Use those x-intercepts to write factors of the function by subtracting their values from x. For example, 2 and 4 are each 1 unit from x = 3, so f(x) = (x – 2)(x – 4) is a possible function.
