Answer: x1=1 x2=-2 and x3=2
Step-by-step explanation:
1st x1=1 is 1 of the roots , so
F(1)=1-1-4+4=0 - true
So lets divide x^3-x^2-4x+4 by (x-x1), i.e (x^3-x^2-4x+4) /(x-1)=(x^2-4)
x^2-4 can be factorized as (x-2)*(x+2)
So x^3-x^2-4x+4=(x-1)*(x^2-4)=(x-1)(x-2)*(x+2)
So there are 3 dofferent roots:
x1=1 x2=-2 and x3=2
A. 3x-4y would be the answer!
Part 1: Similarities of sine and cosine graphs are that both has an amplitude of 1 and a period of 2pi.
A differences between sin and cos graphs includes that sin graph passes through point (0, 0).
The required cosine graph is <span>f(x) = 3 cos(4x - 3π/2) + 4</span>
Answer:
150%
Step-by-step explanation:
To find percentage, divide one number by the other.
39/26 = 1.5
1.5 written as a percentage is 150%
The percentage change in house prices between 2017 and 2018 is -1.13%.
Percentage can be described as a fraction of a number expressed as a number out of hundred. The sign used to represent percentages is %.
In order to determine the percentage change in average house price, the difference between average housing pricing in 2018 and 2017 would be divided by the average house price in 2017 and the result would be multiplied by 100.
Percentage change = [(£469538 - £474902) / £474902] x 100 = -1.13%
