If f(–5) = 0, what are all the factors of the function f(x)=x^3-19x+30? Use the Remainder Theorem.
2 answers:
Answer:
a) (x-2)*(x+5)*(x-3)
Step-by-step explanation:
We are given that f(x) = .
Now, f(-5)=0 i.e. (x+5) is a factor of f(x),
We need to find the other two factors.
So, using Remainder Theorem, we get that f(x) is simplified into f(x) = * (
).
Now, after solving the quadratic equations, we get that,
f(x) = (x+5)*(x-2)*(x-3).
Hence, a) (x-2)(x+5)(x-3) are the factors of f(x).

Answer:
21.3%
Step-by-step explanation:
Given that:
Money spent by Jodie for buying English reading books = 25% lesser than that of Claudia
and
Money spent by Gianna is 9% lesser than that of Claudia.
To find:
By what percent, Gianna spent more than Jodie ?
Solution:
Let the money spent by Claudia on her English books = 100
Now, as per question statement:
Money spent by Jodie = 100 - = 75
Money spent by Gianna = 100 - = 91
Now, to find the answer:
Therefore, Gianna spent <em>21.3% </em>more than the amount that was spent by Jodie.
