tuition can be modeled by an exponential function: y = a(b)x. The variable y represents the cost of tuition per term‚ and the variable x corresponds to the number of years that have passed since the initial year. To find this exponential function‚ make the initial year 1983. During the year 1983‚ zero years had passed since the initial year and the cost of tuition per term was $321‚ making y=321 and x=0. When these numerical values substitute for the variables‚ the equation is 321 = a(b)0. Owing to

Some people are too dependent using calculator in solving simple equation. This attitude will lead people not using critical thinking in solving an equation instead they use calculator for faster result and convenient way. In addition on that‚ internet are vastly used nowadays‚ some students used internet for their projects and searching some articles. Instead

number and not just in mass during the growth. In the experiment we measure the full growth curve of Serratia marcescens by measuring the absorbance at 600nm at every 10 mins. I also determined the viable count at the start and the end of the exponential phase of growth. Using the growth curve I calculated the growth curve and it was 1.2. Using this I found the doubling time which was 34s. Introduction Bacteria grows by binary fission. One bacteria becomes two‚ two bacteria becomes four bacteria

the reaction time if you had reduced the hydrochloric acid by half? Explain why. 4. What should you have learned about reaction rates? 1. The kind of graph that resulted when I plotted the mL of thiosulfate against the time in seconds was an exponential decay. 2. The graph tells us that the rate of reaction increases when there is more thiosulfate as the reaction took more time when there was less thiosulfate. This is shown on the graph by the increasing volume of thiosulfate corresponded to a

Theory There are numerous equations involved in this experiment all of which are important in different ways and are listed below: Equation 1 The first equation of motion for the carriage is: mx.. + cx. + kx = m0eω2sinωt Where: m – Mass of carriage c – Damping coefficient k – Spring stiffness ω – Frequency of input vibrations (Rads/s) m0 – Mass of the out-of-balance rotating masses e – Eccentricity of these masses This is the standard equation of motion for single degree

The Law of Conservation of Mass Goals: 1. To identify the parts of a chemical equation. Students need to identify subscripts‚ coefficients‚ reactants‚ products‚ chemical formulas‚ and chemical symbols 2. To appreciate that scientific discoveries are often the result of inquiry. 3. to distinguish between an element‚ a compound‚ and a mixture (and between heterogeneous and homogeneous mixtures) 4. To balance a chemical equation in order to prove that the Law of Conservation of Mass works quantitatively as well as conceptually

digging. What is x? Given this scenario the Pythagorean Theorem would be the strategy we use to solve for x. I started off with the Pythagorean Theorem. I then plugged the binomials into the Pyth. Thrm. Next I moved (2+6)^2 to le left of the equation by subtracting (2x+6)^2 from both sides. I then squared the expression Next I foiled the expression by multiplying and combining like terms. I multiplied -1 by each term inside the parentheses and then removed the parentheses around the expression

model is made up of the velocity‚ and height. The equation is -16t2 + vt + h. V is equivalent to the velocity‚ and h is equal to the height. The vertical motion falls under the influence of gravity. As the force due to gravity may be opposite to the direction of motion‚ there exists the possibility that the body under force of gravity reverses its direction. It is‚ therefore‚ important to understand that the quantities involved in the equations of motion may evaluate to positive or negative values
