Help? It’s due tomorrow

f(x)= 35x + 85 where x is the number of months

f(x)=350

350= 35x +85

35x= 265

x=7.57

Jasmine need atleast 8 month to have enough money to buy the watch.

< 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

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
