Let's say we're at the store and you want to buy 10 boxes of cookies for a party. Each box of cookies cost 4.89(counting tax), you don't know if you have enough money to buy the cookies with the $65.00 you have with you. You could round the price up to $5.00 and do more simple multiplication. Your total would estimate about $50.00. Now you know you have more than enough money to buy cookies. I hope that makes sense. :)

                                                    Question # 4

Answer:

Total number of cameras left to bid on = 3/5

Step-by-step Explanation:

To determine:

What fraction of the total number of cameras is left to bid on?

Solution Steps:

  • Total number of antique cameras contributed by a local shop = 10
  • The number of cameras accepted for bids = 4

Total number of cameras left to bid on = 10/10 - 4/10

                                                                  = 6/10

                                                                   = 3/5   ∵ As 6/10 = 3/5

Hence, total number of cameras left to bid on = 3/5

                                               Question # 5

Answer:

The remaining portion of tickets = 17/100

Step-by-step Explanation:

To determine:

What portion of the tickets remain?

Solution Steps:

  • The total number of tickets = 100
  • The number of tickets that were sold in first week = 83

The remaining portion of tickets = 100/100 - 83/100

                                                       = 17/100

Hence, the remaining portion of tickets = 17/100

One zero of f(x)=x^3-2x^2-5x+6 is 1 what are other zeros of the function

Answers

Answer:

The other zeros are -2 and 3.

Step-by-step explanation:

As 1 is a zero then (x - 1) is a factor so we divide:

x - 1 )x^3-2x^2-5x+6(x^2-x-6

        x^3-x^2

              -x^2-5x

              -x^2+x

                      -6x+6    

                      -6x+6

                       ...........

x^2 - x - 6 = 0

(x - 3)(x + 2)

x = -2, 3.

Answer:

-2 and 3

Step-by-step explanation:

Given one zero of f(x)=x^3-2x^2-5x+6 to be 1 this means that x-1 is a factor of the polynomial x³-2x²-5x+6

Before we can get the other two factors. We need to divide the polynomial function by x-1 and factorize the resulting quotient as shown in the attachment.

Quotient Q(x) = x²-x-6

Factorizing this function

x²-3x+2x-6 = 0

x(x-3)+2(x-3) = 0

(x+2)(x-3) = 0

x+2 = 0 and x-3 = 0

x = -2 and x= 3

Therefore the other zeros of the function are -2 and 3
