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.

Evaluate the function fx = 4 * 7^t for x= -1 and x=2

Alex73 [517]

Well what i think you're asking here...I apologie if I'm wrong but what I did was

f(-1) = 4 * 7^t = 4/7

and

f(2) = 4 * 7^t = 196.

Is this what you wanted if not I can...try another way.
