The points a, b, c, and d are taken in order on the circumference of a circle. chords ac and bd intersect at point e. mabarc = 76° and mcdarc = 80°. draw chord ad. find m∠aeb.

Step-by-step explanation:

The angle where the chords cross is the average of the two intercepted arcs:

  ∠AEB = (∠AOB +∠COD)/2 = (76° +80°)/2 = 78°

___

Chord AD connects points A and D.

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
