4 times 8 is 32.  But you could halve 4 and double 8 to get the same result:
2(16) = 32.  You could halve 1 and double 16 to get the same result:  1(32)=32.

The radiuses of two intersecting circles are 17 and 39. The distance between their centers is 44. Find the length of their commo
antoniya [11.8K]

Answer:

If x is the distance from centre fo the circle, with radius 25cm, to its intersection point with the common chord, x²+24²=25² =>x=7cm.

Distance from this intersecting point to the centre of the other circle=39–7=32cm

Ratio of the sides of the right triangle thus formed is 24:32=3:4. Since 3:4:5 is the basic pythagorean triplet, the radius of the other circle=5*24/3=40cm.

Aliter: radius of the other circle=√32²+24²= 40cm.

Part C
Anna71 [15]

When 'c' is negative both p and q would have the same sign and when opposite signs whereas when b is positive and negative, both would have positive and negative signs respectively.

<h3>How the signs affect the factored form</h3>

The ways in which the signs of 'b' and 'c' affect the form include;

  • if c is negative, then p and q have opposite signs.
  • If c is positive, then p and q have the same signs.
  • If b is negative, both the signs of  p and q would be negative.
  • Also, if b is positive, then  the signs of both p and q would be positive.
