Answer:

Step-by-step explanation: AB = 6-2=4 BC = 3 ( 3- ) = 6 ∙

<h3>Calulate AC find the formula ~ d = ≅\sqrt{x} 2-x1) + (x2 - y2) = 3,2 AC = \sqrt[n]{x} (3+3)2 + ( 2 - 6 ) 2 = \sqrt[n]{x} 36 + 16 = \sqrt{} 52 P = 4 + 6 \sqrt{} 52   17.21 to dec. places\\</h3>

Find the first derivative?
professor190 [17]
You could do the question the way it is  written, but it is far easier to bring the negative power up to the numerator.

y= x^2 - 3. The derivative of that is
dy/dx = 2x The three is a constant and is always dropped when a derivative is taken
d(-3)/dx = 0

If you are a purist and want to solve the question the way it is written, you could do it this way.

dy/dx = d(1)/dx x^-2 - d(x^-2)/dx * 1
             ======================                    
                          (x^-2)^2

dy/dx =  - (-2 x^ - 3) / x^-4

dy/dx = 2 x^-3 * x^4
dy/dx = 2 x^(-3 + 4)
dy/dx = 2x ^ 1
dy/dx = 2x <<<<< answer

Evaluate 3ab for a=2 and b=3
vampirchik [111]

Answer:

18

Step-by-step explanation:

For this problem, we will simply plug in the values of a and b into the respective variables in the expression 3ab to "evaluate" the expression.

a = 2; b = 3

3ab

Note, that when variables like a and b are smashed with a constant, the use of multiplication is in play.

3ab = 3 * a * b

With this in mind, let's plug in the values of a and b into the expression.

3ab

= 3 (2) (3)

= 3 (6)

= 18

Hence, 3ab evaluated when a=2 and b=3 is 18.

Cheers.
