Sally's huge dog weighed 175 pounds in 2018 and then weighed 145 pounds in 2020. What was the rate of change in weight? pounds per year?

15 lbs per year

Step-by-step explanation:

Huge dog lost 30 lbs in a span of 2 years so divide to find rate of change which is 15lbs per year

-15 pounds per year

Step-by-step explanation:

We can first list out all the information like Year, Weight

so (2018, 175) and (2020,145)

It asks to find the slope, so we just use the slope formula

175-145/2018-2020 = 30/-2 which is -15

good luck!

< 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
