What number goes in the box in the followng sequence 5 11 23 ? 95 191​
Alina [70]

Answer:

47

Step-by-step explanation:

The number that should go after 23 is 47.

The pattern seems to be (n * 2) + 1, where n is the value of the previous number.

We start with the number 5:

5

(5 * 2) + 1  = 11

11

(11 * 2) + 1 = 23

23

(23 * 2) + 1 = 47

47

... and so on

The pattern should continue as follows.

Hope this helps!

What is the maximum value of f(x)=−4x2+4x−2?
horrorfan [7]

Answer: -1

Step-by-step explanation: A typical quadratic equation is ax^{2} +bx+c and the maximum value formula is -b/2a, so let plug it in -4/2(-4) which equals 1/2. Then let plug 1/2 into the equation,

-4(1/2)^2+4(1/2)-2=

    -1+2-2=

If 2.5 is a root of the equation 2x^2+5x−q=0, what are the possible values of q?
bulgar [2K]

Answer:

q = -2510 +5 = \pm \sqrt{5^2-4*2*q} \\ 225 = 25-8q \\\\8q = -200 \rightarrow q = -\frac {200}8 = -25

Step-by-step explanation:

Grab the generic solution of the equation. \frac 52 = \frac{-5 \pm \sqrt{5^2-4*2*q}}{2*2}. Let's isolate the radical, and square both sides.10 +5 = \pm \sqrt{5^2-4*2*q} \\ 225 = 25-8q \\\\8q = -200 \rightarrow q = -\frac {200}8 = -25
