Act like it's a whole circle and find the perimeter, then divide by 2.

P = 2 * pi * r

P = 2 * 3.14 * 9

P = 56.52

Now divide by 2:

P = 28.26

Find the X intercept and the Y intercept from the following linear equation X+ 4y = -56
stealth61 [152]

Answer:

x-intercept = -56

y-intercept = - 14

Step-by-step explanation:

x + 4y = -56

x- intercept :

y = 0

x + 4*0 = - 56

x-intercept = -56

y-intercept:

x=0

0 + 4y = - 56

4y = -56

y = - 14

y-intercept = - 14

Find all of the points of the form (x, −x) which are 7 units from the origin.
Morgarella [4.7K]

Answer:

  • (-7, 0) and (7, 0)

Step-by-step explanation:

<u>All the points that are 7 units from the origin are on the circle:</u>

  • x² + y² = 7²

<u>The maximum and minimum values of x obtained when y = 0:</u>

  • x² = 7²
  • √x² = √7²
  • x = ± 7

So

  • min x = -7 and
  • max x = 7

<u>The points are:</u>

  • (-7, 0) and (7, 0)
