Answer:
Using the graph as your guide, complete the following statement.
The discriminant of the function is
Step-by-step explanation: Remember a parable of the form f(x) = a
, satisfy:
(1) has only one root if and only if [tex] b^2 - 4ac = 0[\tex]
(2) has two real roots if and only if [tex] b^2 - 4ac > 0[\tex]
(3) has two complex roots if and only if [tex] b^2 - 4ac < 0[\tex].
The number b^2 - 4ac is called the discriminant of the parable f(x).
From the graph we can see that the parable has only one root approx in x =1. Thus from point (1) we can conclude that the discriminant should be zero.
PD: a root of a polynomial f(x) is a number a such thast f(a) =0.
The answer is A.
Answer:
ok so if it is 0.7 to buy fruit and 0.6 to buy a cd so we turn these into fraction and multiply
7/10*6/10=42%

Answer: C. Package 3
First, find out what each cell phone package costs for 1 month by dividing the cost by however many months:
Package 1: $160 ÷ 4 = $40 for 1 month
Package 2: $128 ÷ 4 = $32 for 1 month
Package 3: $60 ÷ 2 = $30 for 1 month
Since package 3 costs the least amount of money for 1 month out of all of the other packages, that package offers the best deal. So C) Package 3 is your answer
A benefit is the technology can be more aaurate and you can use a compass and a straightedge wrong and get lost. Also the compass can break
