Cumulative Number of Deaths from AIDS 483,920
500,000
458,551
450,000
The bar graph shows the cumulative number of
deaths from AIDS in the United States, from 1990
through each of the years 1996 to 2002
The data in the graph can be modeled by the
following polynomials, in which f(x) and g(x)
represent the cumulative number of AIDS deaths x
years after 1990
f(x) = - 2217x2.57,570x + 107.896
g(x) = -86x3 - 698x2 + 50, 612x + 113.438

Use f(x) to find the cumulative number of AIDS deaths in 2002
(Simplify your answer)

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
