3 3/4÷ 1/4
15/4÷1/4
15/4÷4/1
15*4=60
4*1=4
60/4=15
15 times 1/4 can fit into 3 3/4.

Step-by-step explanation:
Step-by-step explanation:
Assume c = 0
Using the formula for the x-coordinate of the vertex, b can be calculated in terms of a:
B can then be substituted into the quadratic equation, along with the coordinates of the vertex, to solve a:
AND
Substituting into the quadratic equation:
Because a is negative, the parabola opens up.
