What is the average rate of change for this quadratic function for the interval from x= 1 to x = 3?

The average rate of change of function is -4 in [1,3]

Step-by-step explanation:

The average rate of change for graphic quadratic function for the interval from x=1 to x=3

The average rate of change of a function is change y over change in x.

where,

a=1 and b=3

Using graph we will find f(1) and f(3)

f(3)=-8

f(1)=0

Hence, The average rate of change of function is -4 in [1,3]

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
