After a rain, water drips from a hole in a gutter into a barrel. The weight of the barrel is measured in grams and given by f(t)=10+500 at any time after the water begins to drip. since f(t) represents the weight of the barrel in grams, the 10, and 500 on the right side of the equation must have the unit grams, minutes, and grams per minute, in some order . Match the 10,t, and 500 with their correct units.

< 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

the answer is a

step-by-step explanation:

(x+3)(x+7)

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
