PLEASE HELP WILL MARK BRAINLIEST!!!!!! Base the question off this info: An experienced cashier at a grocery store takes 2 second
Vesna [10]
You need to use basic algebra for this.
For this I’ll use o as the items and p for the payment. First you need to find out how long it took for all the items to scan, so if it took each item 2 seconds to be scanned you need to times the total number of items (o) by two e.g. o x 2 = 62 items times two seconds which is equivalent to 62 seconds (1.02 minutes) after this step you need to minus the total time it took to scan the items for the transaction time (2 minutes) e.g. 2.00 - 1.02 = 2.58 minutes.

Hope this helped :)

Differentiate x^2/4-x^3​
Ede4ka [16]

Answer:

  x^4 + 8x          

  -----------------

    (4-x^3)^2

Step-by-step explanation:

d /dx  (x^2/(4-x^3)​)

When we differentiate a fraction u/v

df/dx = u/v

         =  v du/dx-u dv/dx

           ---------------------------

                         v^2

we know u = x^2   so du/dx = 2x

               v = (4-x^3)  so dv/dx = -3x^2

d dx =   (4-x^3) (2x)- x^2 ( -3x^2)

           -------------------------------------

                   (4-x^3)^2

Combining terms

           (8x-2x^4) --3x^4

           -------------------------------------

                   (4-x^3)^2

           8x-2x^4 +3x^4

           -------------------------------------

                   (4-x^3)^2

             x^4 + 8x          

           -------------------------------------

                   (4-x^3)^2

Match each function formula with the corresponding transformation of the parent function y = 3x
kodGreya [7K]

Answer:

1. y = -3^ x Translated up by 1 unit 2.

2.y = 3^ -x Reflected over the y-axis 3.

3.y = 3 ^x - 2 Translated right by 2 units 4.

4. y = 3 ^x + 1 Translated down by 2 units 5.

5. y = 3^ x + 1 Translated left by 1 unit 6.

6. y = 3 ^x - 2 Reflected over the x-axis
