You work at a store that sells laptops. Your boss ask you to do a sales research and suggest the best model that projects the sales in September for the current year. Month Month Value Sales (in thousands)

September

Determine the equation. Use parenthesis around the exponent!

Round all parts of the equation to 2 decimal places.

What is the r-value?

Using your model, predict the amount in September.

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.

so, converting firstly the mixed fractions to improper fractions and then "adding".
