Answer 1

3) Solution first we find the linear function to correspond to candles height The candles height be y & time it takes be x. Since the relation is linear they must follow . u = matc its corresponding Where m represents the slope of graph. Now given that m = -06 also 4(15) = 15". i 15 = (-0.6) 15 tc 15 + 9 = c Thus we get y = -0.6x + 24 This when - 20 y=40.6)X20+24 y = 24-12 y = 12 cm
