You used three methods of analysis to find the acceleration of the cart on the track: a two-point difference from v(t), an average of a(t) that was itself calculated by a succession of first differences of the v(t) data, and a line fit to v(t). some criteria to help you consider which method is best are part a in which type of graph(s) is it easiest to see whether the acceleration was constant?

Answered by answersmine AT 22/10/2019 – 02:29 AM The best way to find that you want is the line fit. When acceleration is constant the speed(v) changes smoothly every moment, so the v line must be straight. Differently, the accelaration changes.

Sam is measuring the velocity of a car at different times. After two hours, the velocity of the car was 50km/h. After six hours, the velocity of the car is 54km/h. Part A: Write an equation in two variables in standard form that can be used to describe the velocity of the car at different times. Show your work and define the variables used. (5points) Part B: How can you graph the obtained in Part A for the first seven hours? (5points)

Answered by answersmine AT 22/10/2019 – 02:54 AM You are given the time and speed so from there you can get the points (2,50) and (6,54) once you got that you can see how the slope is 1 and b=48x-y=-48 (standard form) part B= 1    492    503    514    525 …

Best answer get Brainliest. 50 points. Emerson earns money from walking dogs and answering surveys. He earns $5 a week for each dog he walks and $0.10 for each survey he answers. Last week, Emerson answered 100 surveys and earned $35. Part A: Create an equation that will determine the number of dogs he walked. (3 points) Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points) Part C: How many dogs did Emerson walk last week? (1 point)

Step-by-step explanation: 5x + 10 = 35 is your equation 5x = 35 – 10    bc u brought the 10 to the other side so its symbol changes 5x = 25         now were going to bring 5 to the other side to do that we …

The side of a square measures (3x − 6) units. Part A: What is the expression that represents the area of the square? Show your work to receive full credit. (4 points) Part B: What are the degree and classification of the expression obtained in Part A? (3 points) Part C: How does Part A demonstrate the closure property for polynomials? (3 points)

A. The area of a square is given as: A = s^2 Where s is a measure of a side of a square. s = (2 x – 5) therefore, A = (2 x – 5)^2                   Expanding, A = 4 x^2 – 20 x + 25   B. The degree …

The quote below was part of a campaign speech given by Senator Albert J. Beveridge in 1898: “But today we are raising more than we can consume. Today we are making more than we can use. Today our industrial society is congested; there are more workers than there is work; there is more capital than there is investment. We do not need more money—we need more circulation, more employment. Therefore, we must find new markets for our produce, new occupation for our capital, new work for our labor.” Which type of policy was this statement intended to justify?

The correct answer is imperialism. Imperialism is when one country tries to extend its power over another country or territory. This can be done through warfare or the signing of treaties/agreements.

Part A: Write functions to represent the number of marigold plants and the number of sunflower plants in the back yard throughout the months. (4 points) Part B: How many marigold plants are in the back yard after 3 months? How many sunflower plants are in the back yard after the same number of months? (2 points) Part C: After approximately how many months is the number of marigold plants and the number of sunflower plants the same? Justify your answer mathematically. (4 points)

If a quantity A is decreased by 15%, it means that what is left is 85% of it. 85%A= Part A. Consider the 150 marigolds. After the first month, 0.85*150 are leftAfter the second month, 0.85*0.85*150=After the third month, 0.85*0.85*0.85*150 = ..so After n months,  marigolds are left. in functional notation:  is …
