Question

Help please!

A manufacturer is designing a two-wheeled cart that can maneuver through tight spaces. On one test model, the wheel placement (center) and radius is modeled by the equation (x + 1.5)^2 + (y + 1)^2 = 9. What is the graph that shows the position and radius of the wheels?

Answer 1

@RadEn can you help me?

Answer 2

there very close to the same range in points so it's very hard to tell

Answer 3

the generally form of the circle equation is
(x-h)^2 + (y-k)^2 = r^2
with h,k is the centre coordinat and r its radius of circle
for this case, given the centre of circle is (-1.5, -1) and its radius r=3

Answer 4

so then would it look something like this? (-1.5+1)^2+(-1+1.5)=3^2?

Answer 5

(x-(-1.5))^2 + (y-(-1))^2 = 3^2
according information above

Answer 6

okay , so what would i do next?

Answer 7

find the match option :)

Answer 8

okay , once second :)

Answer 9

use ur eyes be careful :p

Answer 10

because ur diagram too small :p

Answer 11

oh lordy im scared now lol , oh and also is my x axis going to be -1.5 ?

Answer 12

if i dont be mistake, the true graph is A :)

Answer 13

thanks so much! =)

Answer 14

you're welcome
