Which sentence is true about a ray?

a. a ray is formed by lines that do not cross each other.

b. a ray is formed by an endpoint and a line is starting at the endpoint and going to forever in one direction.

c. a ray is formed by two lines that cross at one point.

d. a ray is formed when two points on a line are labeled

B. A ray is formed by an endpoint and a line is starting at the endpoint and going to forever in one direction.

Step-by-step explanation:

Given choices are :

A. a ray is formed by lines that do not cross each other.

B. A ray is formed by an endpoint and a line is starting at the endpoint and going to forever in one direction.

C. a ray is formed by two lines that cross at one point.

D. a ray is formed when two points on a line are labeled

Now we need to determine about which sentence is true about a ray.

We know that a ray has one fixed end point and other point moves infinitely then correct choice is :

B. A ray is formed by an endpoint and a line is starting at the endpoint and going to forever in one direction.

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
