I strongly recommend that you find an illustration of an ellipse that features the three distances a, b and c.  You could Google "ellipse" and sort through the various illustrations that result, until you find the "right one."

There is an equation that relates a, b and c for an ellipse.  It is a^2 = b^2 + c^2.

a is relatively easy to find.  It is the distance from the center (0,0) of your ellipse to the right-hand vertex (20,0).  So a = 20.

b is the distance from the center (0,0) of your ellipse to the right-hand focus (16,0).  So b = 16.  You could stop here, as it was your job to find b.

Or you could continue and find a also.  a^2 =b^2 + c^2, so

here    a^2 = 16^2 + 20^2.  Solve this for a.

M(-5,9) and N(-2,7)<br> P(-3,-7) and Q(3,-5
jek_recluse [69]

Answer:

M=(4,112)=(4,5.5) A

Step-by-step explanation:

The midpoint for two points P=(px,py) and Q=(qx,qy) is M=(px+qx2,py+qy2).

We have that px=3, py=2, qx=5, qy=9.

Thus, M=(3+52,2+92)=(4,112).

A manufacturer of bicycles has determined that 550 bikes per month will be sold at a price of $250. At a price of $150, it is es
iogann1982 [59]

750 bikes would be sold for $350

Let x represent the number of bikes sold per month and y represent the price.

550 bikes are sold at a price of $250, this can be represented by (550, 250). Also, 750 bikes is sold at a price of $150, hence it is represented by (750, 150)

A linear function is represented by:

y = mx + b

m is the slope, b is the y intercept.

Therefore the function is:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-250=\frac{150-250}{750-550}  (x-550)\\\\y=\frac{1}{2}x-25

The number of bikes sold for $350 is:

350 = (1/2)x - 25

x = 750

Therefore 750 bikes would be sold for $350

Is the square root of 12 rational or irrational?
Andreyy89
<h3>Answer: Irrational</h3>

We cannot write sqrt(12) as a fraction of two whole numbers

Note how sqrt(12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).

Compare this to something like sqrt(16) = 4 which can be written as a fraction 4/1, so sqrt(16) is rational
