Plz answer the question in the picture asap todays the last day i can do it 20 points
plz answer

The population of the town is 0.976 times the population of the town in the previous year.

D is correct.

Step-by-step explanation:

We are given a function which represent population of a town after t years.

f = 19,350(0.976)^t

It is an exponential function. Exponential function wither decease or increase it depends on factor.

y=a*b^t

b is factor which decides factor of exponential function decrease or increase.

If b >1 then function increase

If 0<b<1 then function decrease.

If we see our problem

f = 19,350(0.976)^t

Here, b=0.976<1

Function would be decrease by factor of 0.976

Thus, The population of the town is 0.976 times the population of the town in the previous year.

Give me 5 star/brilliant and let me know you other questions..

thanks

< 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
