Given co bisects zdon. what
is the measure of minor arc ma?

from figure angle(DON)=90 and CO bisects it. so angle(COD)=90/2=45 degree=45pi/180 rad=pi/4 rad so arc(MA)=r*pi/4 where r=radius of circle=OA so arc(MA)=(OA)pi/4

the 3rd option is right

step-by-step explanation:

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
