The sum of 4 consecutive integers is 40 what is the third number in this sequence?
Dmitry [639]
Let's represent the numbers by : x, x+1, x+2, x+3
x+x+1+x+2+x+3=40                     The third number in the sequence is x+2
4x+6=40                                           8.5+2=10.5
4x+6-6=40-6                               Therefore the third number in the sequence is
4x=34                                             10.5
4x/4=34/4
x=8.5

Use the function f(x) = x2 − 2x 8 and the graph of g(x) to determine the difference between the maximum value of g(x) and the mi
slamgirl [31]

The difference between the maximum value of g(x) and the minimum value of f(x) is 5.

Given function is:

f(x)=x^{2} -2x+8......(1)

<h3>What is the general form of a quadratic equation?</h3>

The general form of a quadratic equation is ax^{2} +bx+c=0 with a\neq 0.

As we know the minimum value of a quadratic function is \frac{4ac-b^{2} }{4a} when a>0

For f(x) a>0 so minimum value of f(x) = \frac{4*1*8-(-2)^2}{4*1}=7

From the graph, the maximum value of g(x) =12

So, the difference between the maximum value of g(x) and the minimum value of f(x) =12-7 =5

Hence, the difference between the maximum value of g(x) and the minimum value of f(x) is 5.
