What is the patern in the values as the exponents increase? powers of 3. value3^-1. 1/33^0. 13^1. 33^2. 9a. add 3 to the previous valueb. subtract 3 from the previous valuec. divide the previous value by 3d. multiply the previous value by 3

D. multiply the previous value by 3

Step-by-step explanation:

The pattern of values as the exponents increase is

1/3, 1, 3, 9

Comparing 1/3 to 1, we either add 2/3 or multiply by 3.

Comparing 1 to 3, we either add 2 or multiply by 3.

Comparing 3 to 9, we either add 6 or multiply by 3.

The constant in this pattern is multiplication by 3.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
