How can the zero product be applied to real life
ddd [48]

Answer:

The zero product property states that if a⋅b=0 then either a or b equal zero. This basic property helps us solve equations like (x+2)(x-5)=0.

The Zero Product Property simply states that if ab=0 , then either a=0  or  b=0 (or both). A product of factors is zero if and only if one or more of the factors is zero.

You are saving money to buy a used car. You deposit $2,500 in an account that earns interest compounded annually. The expression
seraphim [82]

Answer:

r= [(\frac{A}{2500}) ^\frac{1}{2} -1]

Step-by-step explanation:

Given data

Principal = $2500

time t= 2 years

Required

the rate r

Given the expression for the balance 2500(1+r)^2

Hence

A= 2500(1+r)^2

we can make r subject of formula

r= [(\frac{A}{P}) ^\frac{1}{t} -1]

r= [(\frac{A}{2500}) ^\frac{1}{2} -1]

Hence, for any value of A, we can find the rate using the expression above
