The average median income for a dentist is $142,740. The average median income for a medical and health service manager is $86,4

KiRa [710]

A: For the Dentist, their average income in 30 years is $4,282,200

B: For the Manager, their average income in 30 years is $2,592,000

C: The difference in both their earnings is $1,690,200

Work: So, I just multiplied their average earnings by 30, and that's what their average income will be in 30 years. For the difference, I subtracted the higher earning by the lower earning, and that's the difference.

I hope this helps you. :)

Derive the equation of the parabola with a focus of (-5,-5) and a directrix of y=7.

adoni [48]

Answer:

$y=-\frac{1}{24}(x+5)^2+1$

Step-by-step explanation:

The given parabola has its focus at (-5,-5) and the directrix is at: y=7.

The equation of such parabola is given by the formula:

$(x-h)^2=-4p(y-k)$

The vertex of the parabola is the midpoint of (-5,-5) and (-5,7).

$(\frac{-5+-5}{2},\frac{-5+7}{2} )=(-5,1)$

The value of p is the distance from the (-5,-5) to (-5,1).

p=|1--5|=6

We substitute the values of the vertex and p into the equation to get;

$(x--5)^2=-4(6)(y-1)$

$(x+5)^2=-24(y-1)$

$y=-\frac{1}{24}(x+5)^2+1$
