On one stretch of road, any vehicle travelling faster than 25 m/s is breaking the speed limit The detectors are placed 1.2 m apart. Calculate the speed of a car that takes 0.050s
to
travel this distance. Is it breaking the speed limit?

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )

1) letter c.

2) 4 square root of 9

hope this
