Can someone help me with number 25

Mathematics

Sure.
The rule says that "The 'n'th term is  2^n + 1. "

You're asked to find the 5th term, so plug '5' into the rule in place of 'n'.

The 5th term = 2^5 + 1

2^5 = 2 x 2 x 2 x 2 x 2 = 32

The 5th term = 32 + 1 = <em>33</em> .

Rachel wants to know the mean price of all the sunglasses on a display rack.
devlian [24]
The mean price of the sunglasses is $17.

If you add up all the values, you will get a total of 136. Now, divide this total by the total number of values. 

There are 8, so 136 divided by 8 is 17. That is the mean.

Brainlist to whoever shows me how to solve this step by step.
Andrews [41]

Answer:

  x ∈ {-4, 2}

Step-by-step explanation:

The x-coefficient (+2) is the sum of the constants in the binomial factors of the equation, and the constant term (-8) is their product.

Since you're familiar with the divisors of 8, you know that the two factors of -8 that total +2 are -2 and +4. These are the constants in the binomial factors:

  f(x) = x^2 +2x -8

  f(x) = (x -2)(x +4)

The roots of f(x) are the values of x that make these factors be zero. They are x=2 and x=-4.

The roots of f(x) are -4 and 2.

_____

Above is the solution by factoring. We can also "complete the square" to find the roots. Anytime we're looking for roots, we want the values of x that make f(x) = 0.

  x^2 +2x -8 = 0

  x^2 +2x = 8 . . . . . add the opposite of the constant

  x^2 +2x +1 = 8 +1 . . . . . add the square of half the x-coefficient: (2/2)² = 1

  (x +1)² = 9 . . . . . . . . . . . write as squares

  x +1 = ±√9 = ±3 . . . . . . take the square root

  x = -1 ± 3 . . . . . . . . . . . subtract 1

The roots are x=-4, x=2.

Given the function <img src="https://tex.z-dn.net/?f=g%28x%29%3Dm%28-2x%2B2%29%5E5-n" id="TexFormula1" title="g(x)=m(-2x+2)^5-n"

Answer:

<h2>See the explanation.</h2>

Step-by-step explanation:

The given function g(x) is a continuous function, since, for any x we can find a real value of the function.

A. \frac{d g(x)}{dx} = 5m(-2x + 2)^{4} \times (-2).

Since, m is a constant, which is not equals to 0, the above value of the differentiation of the function, will be negative.

For x = 1, the above value is 0, that is at x =  1, the function has either maximum value, or a minimum value.

B. As per the above information, we have get that for x = 1, \frac{d g(x)}{dx} = 0.

Hence, the function's critical point's x coordinate is x = 1.

The x- coordinate of the given point is not dependent on m or n.

Hence, proved.
