Answer: 
Step-by-step explanation:
Let the given parabolic mirror opens upwards and vertex=(0,0)
Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror. ∴ p=2
Since, the parabola opens upward, then the equation of the parabola is of the form 
Substitute the value of p=2 in this, we get the equation of the parabolic mirror
Hence, the equation of the parabola that models the cross section of the mirror is

The ratio for the percent increase has a smaller denominator than the percent decrease.
Step-by-step explanation:
From 45 to 75, the increase is 30
If we check the % increased, (30/45)*100 = 66.667%
If we decrease the price from 75 to 45, the amount is same, i.e. 30 but the denominator is changed.
(30/75)*100 = 40%

Answer: The probability is 2/7.
Step-by-step explanation:
Ok, suppose you meet a random person.
The possible days in which that person was born are the seven days of the week, so the total number of outcomes is 7, and we will assume that the probability is evenly distributed for all the days.
Now, we want to calculate the probability that this person was born on a Monday or a Friday.
So we have 2 possible outcomes out of 7.
Then the probability will be equal to the quotient between number of of outcomes that meet the conditions (Monday and Friday, 2 outcomes) and the total number of outcomes (7)
P = 2/7
