Rebecca has 30 paintings to sell. the amount of money rebecca makes from selling x paintings is represented by a function.
f(x)=25xf(x)=25x
what is the practical domain of the function if rebecca sells 30 paintings?
1. all real numbers
2. all integers from 0 to 30, inclusive
3. all multiples of 25 between 0 and 750, inclusive
4. all integers from 0 to 25, inclusive

Option 2 is correct.

Step-by-step explanation:

Rebecca has 30 paintings to sell.

The amount of money Rebecca makes from selling x paintings is represented by a function.

where, x is number of painting to sell.

As we are given total number of painting for sell is 30.

Domain: It is input value of x where function and situation defined.

Minimum number of painting she could sell be 0 and Maximum number of painting she could sell be 30.

Domain:  0≤x≤30

Hence, All integers from 0 to 30, inclusive.

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.
