Describe the sequence of transformations that would take the graph of f(x)=x² to each parabola described below. focus: (1/4,0),directrix: x=-1/4

The parabola obtained is x=y²

Step-by-step explanation:

Given the focus (1/4,0) and directrix: x=-1/4

A point on the parabola is determined by the distance of that point with the focus and with the directrix:

Distance between the parabola and the directrix:

Distance between the parabola and the focus:

=

=

x=y²

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
