The flow of traffic at certain streetcorners can sometimes be modeled as asequence of Bernoulli trials by assumingthat the probability of a car passingduring any given second is a constant pand that there is no interaction betweenthe passing of cars at different seconds.If we treat seconds as indivisible timeunits (trials), the Bernoulli model applies.Suppose a pedestrian can cross thestreet only if no car is to pass during thenext 3 seconds. Find the probability thatthe pedestrian has to wait for exactly 4seconds before starting to cross.

Let constant p represents a car that is passing during any given second. Let q represents a car…

A piece of wood moves at a velocity (measured in millimeters per year) of v(1) = r² – 3t – 4 where 1 = 1 would be the end of the first year. If a is the displacement of the wood in the first 5 years and b is the distance traveled in the first 5 years, what is a- b? None of the listed answers
High-speed motion pictures (3500 frames/second) of a jumping 230 μg flea yielded the data to plot the flea's acceleration as a function of time as shown in the figure ( Figure 1). (See "The Flying Leap of the Flea," by M. Rothschild et al. in the November 1973 Scientific American.) This flea was about 2 mm long and jumped at a nearly vertical takeoff angle. Use the measurements shown on the graph to answer the questions. Figure alg 150 100 50 0 0 0.5 1.0 1.5 Part E Use the graph to find the flea's maximum speed.

A car is initially traveling at a rate of 65 feet per second. The acceleration of the car is 3 feet per second squared. Determine the displacement of the car at time t if the displacement at t=5 seconds is 29 feet. Do not include "s(t)=" in your answer.
A car travels a distance d = 29 m in the positive x-direction in a time of t1 = 21.5 s. The car immediately brakes and comes to rest in t2 = 7 s.Randomized Variablesd = 29 mt1 = 21.5 st2 = 7 s What was the car's average velocity in the horizontal direction, in meters per second, during t1? What was the acceleration, in meters per second squared, during time interval t1, assuming the car started from rest and moved with a constant acceleration? What was the car's instantaneous velocity in the horizontal direction, in meters per second, when it began braking? Using the result from part (c), what was the car's horizontal component of acceleration, in meters per second squared, during the braking period?
The captain of a fishing boat needs to travel 22 miles on his boat. If the captain goes the same direction the current is flowing, his trip would be 4 hours long, but it would be 5 hours long if he goes the opposite direction of the current. Let x represent the rate of the boat if there were no current, and let y represent the rate of the curre nt. Recalling that distance equals rate multiplied by time, what is an equation that describes the situation when the boat is traveling the same direction as the current is flowing.
Suppose your hair grows at the rate of 1/57 inch per day. Find the rate at which it grows in nanometers per second. Because the distance between atoms in a molecule is on the order of 0.1 nm, your answer suggests how rapidly atoms are assembled in this protein synthesis. A certain corner of a room is selected as the origin of a rectangular coordinate system. If a fly is crawling on an adjacent wall at a point having coordinates (3.3, 0.5), where the units are meters, what is the distance of the fly from the corner of the room?
Lesson 4: A Qualitative Look at Rates By considering specific velocity-time functions of the motion of a particle as rate of change functions and then trying to draw 1) a rate of change function of the rate of change function and 2) a function that "undoes" the given rate of change function. Of course, we are talking about creating the acceleration-time function and the position-time functions, respectively, when supplied with a velocity-time function. It is assumed that you have some conceptual knowledge of the derivative as a rate of change function and the definite integral as an accumulation function. As you work through Exploration 4.1, try to reconcile both the physical aspects and the mathematics theory behind your answers. Exploration 4.1: A Qualitative Look at Rates Work with gaining a qualitative understanding of graphs of functions. In particular focus on the relationships between acceleration, velocity, and position vs. time in terms of rates of change of the functions…
