Answer:

dy/dx at x=6 is 0.334

Step-by-step explanation:

The center difference method requires that the values of the function are given in equal intervals which is the case, and allows one to find the value for x = 6 using those of the function for x = 5.5 and for x = 6.5 as follows:

\frac{dy}{dx} =\frac{3.7436-3.4096}{6.5-5.5} =0.334

What is the factorization of the expression below?
olchik [2.2K]

Answer: D. (x-6)(x-6)

Step-by-step explanation:

We have the following trinomial, which is also known as perfect square trinomial, because the first and the third term are squares:

x^{2}-12x+36  (1)

First term:x^{2}  

Third term:36=6^{2}  

If we factorize this expression we have:

(x-6)(x-6)=x^{2}-6x-6x+36=x^{2}-12x+36

As we can see, the trinomial (1) has two factors:

(x-6) and (x-6)

Therefore, the correct option is D.

1. The speed of a planet's moon in orbit is about 29500
g100num [7]

Answer:

  20,114 mi/h

Step-by-step explanation:

It can be convenient to remember that 1 mi/h = 22/15 ft/s. To convert the given number to the appropriate units, we can divide by this conversion factor:

  (29500 ft/s)/((22/15 ft/s)/(1 mi/h)) = (29500·15/22) mi/h = 20113 7/11 mi/h

  ≈ 20,114 mi/h
