Answer:

f(x)= (x-1)(3+\sqrt{5})(3-\sqrt{5})

Step-by-step explanation:

factor further

f(x)= x^3 -7x^2 +10x -4

and as you put it:

f(x)= (x-1)(x^2 -6x +4)

in the instructions, it says that 1 is a zero.

this is because when x=1

you will see that the first section (x-1) will be (1-1) which is 0

when you multiply 0 by anything, it is 0

so the entire thing would then be zero

(x-1) can not be factored further

but x^2 -6x +4 can

factor into  (3+\sqrt{5})(3-\sqrt{5})

use quadratic formula

then put it back into equation

f(x)= (x-1)(3+\sqrt{5})(3-\sqrt{5})

If Julie invests $9,250 at a rate of 7%, compounded weekly, find the value of the investment after 5 years. $13,455.78
STatiana [176]
What is that $13,455.78? Something? I did this and got $13,122.76.  Here's how I did it:
Use this formula
A=P(1+ \frac{r}{n} ) ^{(n)(t)} where A is the ending amount, P is the starting amount, n is the number of times it compounds a year, and t is the number of years.  We have all we need to set it up:
A=9,250(1+ \frac{.07}{52} ) ^{(52)(5)}
First divide and add inside the parenthesis:
A=9,250(1.001346) ^{(52)(5)}
then multiply the exponents:
A=9,250(1.001346) ^{260}
raise the value inside the parenthesis to the power of 260:
A=9,250(1.418676)
and finally multiply to get A = $13,122.76
