The equation s= square root 30(f)(d) can be used to find a car's speed s in miles per hour given the length d in feet of a skid mark and the friction factor f of the road. police measured a skid mark of 90 feet on a dry concrete road. if the speed limit is 35 mph, was the car speeding?

step-by-step explanation:

1/2*qr*rs

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
