Answer:

See graph of the two conics in the attached picture

Step-by-step explanation:

We create two vertices for the ellipse on the y-axis located at the points (0,2) and (0, -2) (marked with orange dots in the picture) and then create the equation for the ellipse such that its focus coincide with the place for the trees as requested. Recalling the formula for the position of the focus (c) for a horizontal ellipse of the form: \frac{x^2}{a^2} +\frac{y^2}{b^2} =1\\c=\sqrt{a^2-b^2} \\

Since our b value is 2 (choice of two vertices above), we have:

c=\sqrt{a^2-b^2} \\3=\sqrt{a^2-2^2}\\3^2=a^2-4\\a^2=9+4=13

So now we can complete the equation of our ellipse with the trees at (-3,0) and (3,0):

\frac{x^2}{13} +\frac{y^2}{4} =1

Now we create the horizontal hyperbola of general form: \frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\c=\sqrt{a^2+b^2}

We request the same values for "c" and for "b" as we did with the ellipse:

c=\sqrt{a^2+b^2} \\3=\sqrt{a^2+2^2}\\3^2=a^2+4\\a^2=9-4=5

So now we can write the equation for this horizontal hyperbola:

\frac{x^2}{5} -\frac{y^2}{4} =1

Both conics are plotted in the attached image, and their respective vertices that correspond to (-\sqrt{13} , 0) and (\sqrt{13} , 0) for the ellipse, and (-\sqrt{5} , 0) and (\sqrt{5} , 0) for the hyperbola, are indicated with blue dots and orange dots respectively.

The location of the trees (focus) is indicated with red dots.

Step-by-step explanation:

n ⋅ n ⋅ p ⋅ p ⋅ r ⋅ r ⋅ r

Write using exponents

There are 2 n terms

n²⋅ p ⋅ p ⋅ r ⋅ r ⋅ r

There are 2 p terms

n² p²⋅ r ⋅ r ⋅ r

There are 3 r terms

At a bargain store.Tanya bought 5 items that each cost the same amount. Tony bought 6 items that each cost the same amount, but
Ray Of Light [21]

(A) For x representing the cost of one of Tanya's items, her total purchase cost 5x. The cost of one of Tony's items is then (x-1.75) and the total of Tony's purchase is 6(x-1.75). The problem statement tells us these are equal values. Your equation is ...

... 5x = 6(x -1.75)

(B) Subtract 5x, simplify and add the opposite of the constant.

... 5x -5x = 6x -6·1.75 -5x

... 0 = x -10.50

... 10.50 = x

(C) 5x = 5·10.50 = 52.50

... 6(x -1.75) = 6·8.75 = 52.50 . . . . . the two purchases are the same value

(D) The individual cost of Tanya's iterms was $10.50. The individual cost of Tony's items was $8.75.
