Answer:

Step-by-step explanation:

givens

x1 = 3

x2 = 4

y1 = 4

y2 = 7

formula

d = sqrt( (x1 - x2)^2 + (y1 - y2)^2 )

solution

d = sqrt( (3 - 4)^2 + (4 - 7)^2 )

d = sqrt ( 1 + 3^2)

d = sqrt( 1 + 9)

d = sqrt( 10)

AVERAGE between 90 and 100%
means not including 90 and 100% but not including 90 or 100%

average=(sum of values in set)/(how many values in the set)

so
4 exams, so there are 4 values
average=(sum)/4

the sum is the known+unknwon
sum=76+99+86+x

so
90<average and average <100
or
90<average<100

lets say average=a

a=sum/number
a=(76+99+86+x)/4

90<(76+99+86+x)/4<100
90<(76+99+86+x)/4 and (76+99+86+x)/4<100

solve each for x and find intersection

90<(76+99+86+x)/4
times 4 both sides
360<261+x
minus 261 both sides
99<x

(76+99+86+x)/4<100
times 4 both sides
261+x<400
minus 261 both sides
x<139

so

99<x<139
since max score is 100
99<x<100

interval notaion is
[99,100]

answer is 2nd one

Which statement is true about the end behavior of the graphed function?

Sloan [31]

D. As the x-values go to negative infinity, the function's values go to positive infinity.

Step-by-step explanation:

In the diagram you notice as the values of x increase to the far negative value, the function's output values increase to positive infinity.

For example at ;

x=-2, f(x)=0

x=-3, f(x)= 16

x= -4, f(x)= >64
