Apark is represented on a map with the following vertices coordinates: vertex 1 is at ( -4, - 1) vertex 2 is at ( - 4, 5) vertex 3 is at (2,5) vertex 4 is at ( 2, -1 ) linsey jogs along the edge of the park in order from vertex 1 to vertex 2 to vertex 3 to vertex 4 and then back to vertex 1 one unit on the coordinate gride equal 20 yd what is the total distance linsey jogged enter the answer in the box

120 yards

Step-by-step explanation:

I drew out all four points then based my answer off of that.

Linsey jogged 6 units on the grid.

Next I converted this 6 units to yards.

20 yards x 6 units

20 x 6 = 120

So Linsey jogged 120 yards

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

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.
