ANSWER
Focus:
Directrix:
EXPLANATION
The given parabola has equation:
We compare this to the general equation,
Comparing the coefficient of x, we have:
-4p=-1
The focus is (-p,0)
The equation of the directrix is
x=p
What conclusion can be based on the given statement? x is a number such that 7x = 7y

Answer:
It is required to draw a number line showing equivalent fractions.
'Equivalent fractions' are the fractions having same value even though the digits involved are different'.
For example: Consider, and
.
Now, we have,
= 0.5
= 0.5
Thus, the both fractions have the same value, even though we are dividing different digits.
Thus, and
are called equivalent fractions.
So, we plot them on the number line, resulting in the following figure with point P = 0.5.
Since we know that Lane is travelling at 180 steps per minute and that each step is 3.25 feet long, we can easily find his running speed in feet/min. This will be equal to
To find the speed in miles per hour, we just perform a <em />dimensional analysis. We can use the conversion factors 5280 ft = 1 mile and 60 min = 1 hr to calculate for the speed in miles per hour:
