The speed s in miles per hour that a car is traveling when it goes into a skid can be estimated by the formula s = V30fd, where f is the coefficient of friction and d is the length of the skid marks in feet. On a highway near Lake Tahoe, a police officer finds a car on the
shoulder, abandoned by a driver after a skid and crash. He is sure that the driver was driving faster than the speed limit of 20 mi/h
because the skid marks measure 9 feet and the coefficient of friction under those conditions would be 0.7. Which of the following is
approximately the speed that the driver was driving at the time of the skid? Round your answer to the nearest mi/h.
A. 23 mi/h
O
OB. 19 mi/h
O C. 14 mi/h
OD. 189 mi/h

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

it is not that hard all u have to do is plot the graph

step-by-step explanation:

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best

step-by-step explanation:

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
