1st = 100% - 20% = 80%
2nd= 100%-15% = 85%

Net Price Factor = 0.8 x 0.85 = 0.68

Net Price = $1899 x 0.68

Final Net Price = $1,291.32

Total Discount= $1899 - 1,291.32 = $607.68

What is the sign of f on the interval -2

TEA [102]

Answer:

$f$ is sometimes positive and sometimes negative.

Step-by-step explanation:

$f(x)=(x-3)(x+2)(x+4)(x+4)(x-1)(2x-9)$

Take $x=-1\in(-2,\frac{9}{2})\ as-2$

$f(-1)=(-1-3)(-1+2)(-1+4)(-1-1)(-2-9)\\\\=(-4)(1)(3)(-2)(-11)\\\\=-264\\\\f(-1)$

Take $x=2\in(-2,\frac{9}{2})\ as\ -2$

$f(2)=(2,-3)(2+2)(2+4)(2-1)(2\times2-9)\\\\=(-1)(4)(6)(1)(-5)\\\\=120\\\\f(2)>0$

Hence $f(x)$ for $x=-1$ and $f(x)>0$ for $x=2$

So $f$ is sometimes positive and sometimes negative in the interval.

Rama09 [41]

Answer:

Step-by-step explanation:

100 is 4 times 25

25*4=100

4*26/25=104/100
