to logistics, supply chains and warehousing. Business math differs from other types of math’s because it consists of more advanced mathematics such as matrix algebra, linear programming and mathematics of finance. Thus, it is perfect to use in the business management field. Not only is Business math a very important type of mathematics but so is Financial Mathematics because they two form important branches of math that are directly applied to business and economics. Examples of these applied math’s that are vital for business are management science, probability theory, time series analysis, linear programming and queuing theory. Business Math 1324 is a very common requirement for many Texas college students who plan to get a degree in the business and/or economics field. Business math prepares these students by teaching them matrix algebra, linear programming and in some cases it also teaches them a little…

I plotted 2 points in Desmos, (2 toppings, 13.85) and (4 toppings, 16.99), both are medium pizzas. I asked students to get the price per topping which is the slope and subtract it two times from \$13.85 to get the base price or the y-intercept. We tested the equation by opening the website of pizza hut. Students are able to compare the prices as well as qualities of the pizza stores. In this activity I was able to engage students in exploring real-world issues and solving authentic problems using…

a point where they knew if there were 23 cans of each flavor, and then they would have a total of 138 cans. From there, if they added one more of each flavor, or six cans to the total they would have 144 cans. If they added six cans two more times they had 156 cans. AnaMaria and Kevin were able to use the previous step to compute their answer. Additionally they knew that if there were six different flavors they could use the function f(x)=6x to calculate how many total cans there were if there…

Have you ever looked at your math paper and questioned why do I have to make a trend line? Is making a trend line really necessary? Well, trend lines allow the user to see a more defined trend of the data. Also, the creation of a trend line allows a correlation between the two subjects to be viewed easier. Trend lines help people accurately determine future outcomes that can come in handy if there is a problem. This is possible because trend lines make it easier to find the slope intercept…

A girl comes out standing on the table and then jumps off and gets low to the ground, does a small roll thing and then stands up bent over with her arms straight up. In that whole scene she went from high topography, low, to medium and also shows curves with her body and straight lines with her arms. Her element is fire the entire time she is on stage. At the end of her scene she shows two more extreme “systems” by falling to the ground again and getting back up to continue her last lines and…

The Kriging weights w_i1,w_i2,w_i3,…w_ik can be used to estimate the fair value of VA contracts x ⃑_i by the following formula, y ̂_i=∑_(j=1)^k▒〖w_ij∙y_j 〗. The kriging weights can be calculated by the following linear equations, Where the is a control variable, which is used to make sure that ∑_(j=1)^k▒w_ij =1. V_rs=α+exp⁡(-3/β D(z ⃑_r,z ⃑_s,λ)),r,s=1,2,3,…,k, D_ij=α+exp⁡(-3/β D(x ⃑_i,z ⃑_j,λ)),j=1,2,3,…,k, The D(.) function is the distance function mentioned in the clustering section,α≥0…

Supply chains that are complex are commonly modeled as linear programs (LPs). They can effectively trade off broad range of criteria. To model FMCG supply chains accurately, one must include discrete aspects of decision making, which requires solving a mixed-integer program (MIP). It has become significantly important for managers, given the widespread use of linear models today, to be able to develop good, efficient models to aid them in the decision-making process. Three important factors;…

a) Heckel equation In 1961, Heckel proposed the most widely used equation describing pharmaceutical powder behavior in compaction. It was initially used to study the densification of ceramics and its correlation with pressure. It a first order process where powder pores elimination rate is correlated to the number of pores present. The rate of volume reduction increases as the number of pores decrease. Heckel equation relates the density, pressure and the pore fraction of the powder [16],.…

Introduction I’m going to start this paper with introducing the history of Pascal’s Triangle, time ranging from 2nd century BC to 18th century AD. Among all the academic works by ancient mathematicians, I’m going to focus on Jiu Zhang Suan Shu [Nine Chapters on the Mathematical Art] composed by Chinese scholars around 2nd century BC-10th century AD. I will use the binomial expansions derived from Pascal’s triangle as an example and then illustrate the coefficients expansion in general. After…
