Write and equation of the translated or rotated graph in general form (picture below)
Svetlanka [38]

Answer:

Option b

Step-by-step explanation:

The equation 4x ^ 2 + 5y ^ 2 = 20 has center in (0,0).

But the transformation T(5, -6) shifts the center of the equation to the point (5, -6).

Therefore, when applying T(5, -6) we will have the following equation translated.

4(x-5) ^ 2 + 5(y - (-6)) ^ 2 = 20.

Simplifying we have:

4(x-5) ^ 2 + 5(y + 6) ^ 2 = 20

Now we expand (x-5) ^ 2 and (y + 6) ^ 2

4(x ^ 2 -10x +25) + 5(y ^ 2 + 12y +36) = 20\\\\4x ^ 2 -40x + 100 + 5y ^ 2 + 60y + 180 = 20\\\\4x ^ 2 + 5y ^ 2 -40x + 60y +260 = 0

The equation of a circle has the form

h(x-a) ^ 2 + q(y-b) ^ 2 = r

For h = 1 and q = 1.

If h \neq 1 and q\neq 1 then the graph becomes an ellipse.

In this problem h = 4 and q = 5 therefore the figure is an ellipse

The area of a circle is 616 cm². Find its circumference. Use π = 22/7
kirill [66]

Area = PI x r^2

Circumference = 2 x r x PI

Using area find the radius )r)

616 = 22/7 x r^2

Divide both sides by 22/7:

196 = r^2

Take the square root of both sides:

r = 14 cm

Now find the circumference:

2 x 14 x 22/7 = 88 cm

Answer : A) 88 cm
