1.Write the equation for an ellipse with vertices (–4, 2), (2, 2), (–1, –2) and (–1, 6).

Nimfa-mama [501]

The general equation of an ellipse:
$\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1
$

we have vertices (–4, 2), (2, 2), (–1, –2) and (–1, 6).⇒⇒⇒ red points
by graphing the points ⇒⇒⇒ attached figure 1
the majority axis is the line connecting (–1, –2) and (–1, 6) and has a distance = 8
the minority axis is the line connecting (–4, 2), and (2, 2) and has a distance = 6
(h,k) represents the center of ellipse which is the intersection between axes
∴(h,k) = (-1,2)
and a = 3 , b = 4
∴ the equation of the ellipse is

$\frac{(x+1)^2}{9} + \frac{(y-2)^2}{16} =1
$

A hyperbola with vertices (9, 3) and (5, 3) ⇒⇒⇒⇒ blue points
and with foci (11, 3) and (3, 3). ⇒⇒⇒⇒ red points
by graphing the points ⇒⇒⇒ attached figure 2
so, the hyperbole axis is horizontal
(h,k) represents the center of hyperbola = (7,3) ⇒⇒⇒ green point
a = distance between center and any of vertices = 7 - 5 = 2
c = distance between center and any of foci = 7 - 3 = 4
∵ c² = a² + b²
∴ b² = c² - a² = 16 - 4 = 12
the general equation of the hyperbole :
 $\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} =1
$
the equation of the hyperbole will be
 $\frac{(x-7)^2}{4} - \frac{(y-3)^2}{12} =1
$

Here is a polygon on a grid. An L shaped figure on a square grid. Draw a scaled copy of this polygon that has a perimeter of 30

yanalaym [24]

Answer: the perimeter of this L shaped figure is 10 units, so scaling it by 3× would make the perimeter 30 units. so the scale factor is 3

Explain why the steps for solving equations are usually given as removing grouping symbols first, even though it is not necessar

finlep [7]

This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)
