If the average (arithmetic mean) of five distinct positive integers is 10, what is the difference between the largest possible v

Arte-miy333 [17]

Answer:

The difference between the largest possible value of the greatest integer and the least possible value of the greatest of the five integers = 4

Step-by-step explanation:

Step 1:-

let 'x' be the number

The sequence of arithmetic progression of distinct positive integers

x , x+1 , x+2 , x+3 , x+4

Given the average of five distinct positive integers is 10

$\frac{x+x+1+x+2+x+3+x+4}{5} = 10$

on simplification , and cross multiplication , we get

5x +10 = 5 X10

5x +10 =50

subtracting'10' on both sides, we get

5x +10 - 10 = 50 -10

5x =40

dividing '5' on both sides, we get

x = 8

The number is '8'

Step 2:-

Now the arithmetic sequence of five numbers are

x , x+1 , x+2 , x+3 , x+4

8 , 9, 10 , 11 , 12

In this sequence is smallest number is '8' and

The largest number is '12'

the difference between the largest possible value of the greatest integer and the least possible value of the greatest of the five integers

= largest possible value - least possible value

= 12 - 8 =4

Final answer = 4

Write the quadratic function in standard form. f(x) = -x2 + 2x + 4 f(x) =

goldenfox [79]

Answer:

$f(x)=-1(x-2)^2+8$

Step-by-step explanation:

Given:

The quadratic function is given as:

$f(x)=-x^2+2x+4$

The standard form of a quadratic function is given as:

$f(x)=a(x-h)^2+k$ , where, 'a', 'h' and 'k' are real numbers.

Now, in order to convert the given function to standard form, we use completing by square method.

$-x^2+2x=-(x^2-2x)=-[(x-2)^2-2^2]=-[(x-2)^2-4]=-(x-2)^2+4$

Now, $f(x)=-x^2+2x+4$ can be rewritten as:

$f(x)=-(x-2)^2+4+4\\f(x)=-1(x-2)^2+8$

Therefore, the standard form of the function is:

$f(x)=-1(x-2)^2+8$

Set it equal to 260, because thats what they all equal. so then do 260-15 because thats the only price we know, 260-15= 245. then do 245/7=35. each bracelet was 35 dollars. to check do 35*7=245 & 245+15 = 260
