The store will charge $3.90 for the bag of chips.
Reason for this is do 1.2*225%(or 2.25) in your calculator to get 2.7.
Then take the 2.7 then add it to the original purchase cost of 1.2 to give you a total of $3.90.

Which statements are true about the polynomial function? f(x)=x3−x2−4x+4
luda_lava [24]
To determine which of the statement is/are true, we simply have to evaluate the given choices.

  a.   f(x) = 0 when x = -1

     f(x) = (-1)^3 - (-1)^2 - 4(-1) + 4
     f(x) = 6

  FALSE

   b. f(x) divided by x - 1 has a remainder of 0.

     f(x) = (1)^3 - (1)^2 - 4(1) + 4
     f(x) = 1 - 1 - 4 + 4 = 0

  TRUE.


   c. (x - 1) is a factor of f(x)

  Since, the division of f(x) by x - 1 gave an answer of zero this means that it is a factor. 

    TRUE.

   d. f(-1) = 0.

 In relation to letter a of this item, if we are to substitute -1 to x of the given equation, the answer is 6 instead of zero.

What did this person do wrong? Honestly really stuck and do not remember geometry!
dmitriy555 [2]

Answer:

See below.

Step-by-step explanation:

Using the right triangle altitude theorem, the correct proportions are:

\dfrac{AB}{AC} = \dfrac{AC}{AD}

\dfrac{AB}{x} = \dfrac{x}{AD}

\dfrac{25}{x} = \dfrac{x}{16}

x^2 = 25 \times 16

x = 20

AC = 20 cm

\dfrac{AB}{CB} = \dfrac{CB}{DB}

\dfrac{AB}{y} = \dfrac{y}{DB}

\dfrac{25}{y} = \dfrac{y}{9}

y^2 = 25 \times 9

y = 15

CB = 15 cm

Exponents? No.

Multiplication or division? Yes!

12 x 12 = 144

144 + 10
