. The mass of each candy in a box is 5 g. The mass of the empty box is 20 g. Let T grams represent the total mass of the box and candies. Let n represent the number of candies, so that
T = 5n + 20
(3) Soso bought two cats, Gretchen and TK, from a pet store in 2015. Gretchen’s
weight was 3 kilograms, and TK 5 kilograms. In 2018, after a period of
growth, Gretchen weighed 6 kilograms and TK 8 kilograms.
2. Is Tawanda making an additive or multiplicative comparison?
Explain your reasoning.
(iii) Write a ratio that compares Gretchen’s kilograms in 2018 to Gretchen’s kilograms in 2015.
(iv) Write a ratio that compares TK’s kilograms in 2018 to TK’s kilograms
in 2015.
(v) Determine which cat gained more weight (grew bigger) using a
multiplicative comparison. Explain your reasoning.
Can [ i ] be a column of a unitary matrix?
[-i ]
Justify your answer
1. F(x, y) = cos(e^t) dt
2.f(x,y,z)=xy^2e^-xz
How many vacant black squares do we have in a chess board with 64 total white and black squares?
create 3 equations of the form ax + by cz = d , where a, b, c, and d are constants (integers between – 5 and 5). For example, x +2y -z = -1 . Perform row operations on your system to obtain a row-echelon form and the solution.
Go to the 3D calculator website GeoGebra: www.geogebra.org/3d?lang=pt and enter each of the equations.
After you have completed this first task, choose one of the following to complete your discussion post.
1. Reflect on what the graphs are suggesting for one equation, two equations, and three equations, and describe your observations. Think about the equation as a function f of x and y, for example x + 2y +1 = z, in the example above. Geogebra automatically interprets this way, that is, like z = f(x,y) = x + 2y +1 , it isolates z in the equation.
2. What did the graphs show when you entered the second equation?
Reflect on the concepts of linear and non-linear systems. What concepts (only the names) did you need to accommodate the concept of linear and non-linear systems in your mind? What are the simplest linear system and non-linear system you can imagine? In your day to day, is there any occurring fact that can be interpreted as linear systems and non-linear systems? What strategy are you using to get the graph of linear systems and non-linear systems?
