Sandra’s lunch came to $12.84 plus 15% tax. What was the total cost of her lunch?
Nimfa-mama [501]

The total would be $14.77

because we will do 0.15x12.84 which is 14.766 but since this is money we round to the nearest hundredth , and that is $14.77

Three consecutive even integers have a sum of -48. Find the largest integer.
kobusy [5.1K]

Answer:

<h3>           - 14</h3>

Step-by-step explanation:

{x -  some integer}

2x  -  the first even integer

2x+2  -  the second consecutive even integer

2x+4  -  the third consecutive even integer (the largest)

2x + 2x+2 + 2x+4  - the sum of three consecutive even integers

2x + 2x+2 + 2x+4 = -48

   6x + 6  = -48

        ÷3         ÷3

    2x + 2 = -16

         +2      +2

     2x+4 = -14

Derive cos (2x - 1)​
ExtremeBDS [4]

Answer:

Step-by-step explanation:

I believe that what you want to do here is to "differentiate" cos (2x - 1).

We must use the rule for differentiating cos x and also the chain rule, since the input to cos x here is (2x - 1).

(d/dx) is the derivative operator.

(d/dx) (cos x) = -sin x

(d/dx) cos (2x - 1) = - sin (2x - 1) * (d/dx) (2x -1) = -sin (2x - 1)(2) = -2sin (2x - 1)
