What is the equation for the translation of x2 + y2 = 16 seven units to the right and five units up?

asambeis [7]

Answer:

(x − 7)2 + (y − 5)2 = 16

Step-by-step explanation:

The given circle has equation

$\sf \: x^2+y^2=16x$

The equation of a circle with center (h,k) and radius r units is

$\sf(x-h)^2+(y-k)^2=r^2(x−h)$

$\sf(x-7)^2+(y-5)^2=4^2(x−7)$

$\sf(x-7)^2+(y-5)^2=16(x−7)$

This is the equation that has its center at the origin with radius 4 units.

When this circle is translated seven units to the right and five units up, then the center of the circle will now be at (7,5).

Inequality: 6r - 200 - 65 $\geq$ 1000 and minimum of 211 people

Step-by-step explanation:

Let r = rides

6r - 200 - 65 $\geq$ 1000

6r - 265 $\geq$ 1000

6r $\geq$ 1265

r $\geq$ 210 $\frac{5}{6}$

Needs 211 people to make a profit of at least $1000
