Question

Can someone check my answers please and if Im wrong please explain.

1) graph 4x^2+4y^2=64. what are the domain and range?

domain;all real numbers
range;-4<=4<=4

2) graph 4x^2+y^2=9. what are its lines of symmetry?

directrix x=-6

Answer 1

years late to the party but all of them are right except for the first!! for anyone else taking the unit 5 lesson 3 circles quiz, here are the rest of the answers too

1. graph 4x^2+4y^2=64. what are the domain and range?
A. domain: -4 <= x <= 4, range: -4 <= y <= 4

7. in a factory, a parabolic mirror to be used in a searchlight was placed on the floor....
A. y = -2/81x^2 + 50

8. what are the vertex, focus, and directrix of the parabola within the given equation?
D. vertex: (4,-5); focus: (4,2); directrix: y= -12

9. write an equation of a circle with the given circle and radius, center (-7,-6) and radius 2
A. (x+7)^2 + (y+6)^2 = 4

10. write an equation for the translation of x^2 +y^2 = 49 by 3 units left and 4 units up
B. (x+3)^2 + (y-4)^2 = 49

11. write an equation in standard form for the circle
C. (x-3)^2 + (y-5)^2 = 64

12. what is in the center and radius of the circle with the given equation? (x-1)^2 + (y-1)^2 = 4
D. center (1,-1); radius 2

13. what is the graph of the equation? (x+8)^2 + (y-1)^2 = 9
B. the circle is on the left side of the graph, near the -8 on the horizontal line. look closely, one is placed slightly higher on the graph than the other.

hope someone out there is saved an extra 10 minutes or so by this
