Rute tez 100 trufas: 15 de cereja, 25 de licor, 50 de chocolate ao leite e o restante de abacaxi
a) Escreva a fração que representa quantas trufas ela fez nos sabores cereja e licor
b) Quantas trufas de abacaxi Rute fez? Escreva a fração que representa esse sabor.
c) Que sabor representadas trufas feitas por Rute?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

ou would have 12 of each

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
