Answer:
x<168
Step-by-step explanation:
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
Answer:
= 14.7 percent
Step-by-step explanation:
= 100 - 85.3
= 14.7 percent
If you would like to find a function which is equivalent to f(x) = 3(1.7)4x, you can do this using the following steps:
<span>f(x) = 3(1.7)4x = 3(1.7)^(4x) = 3(1.7^4)^x = 3(8.35)^x = 3(8.35)x
</span>
The correct result would be B <span>f(x) = 3(8.35)x.</span>
