By the 46th day, there are 400 water lilies in the pond The estimate you made
o close to 46 (or exactly right) because it was
estimated well.
o too low because the quick exponential growth
was not accounted for.
o too high because the exponential growth was
overestimated

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
