Exponential function

Related rates are used in a wide variety of different scenarios from finding how large a spill is increasing, to how fast it may take to empty something. Related rates deal with time, usually have two different variables like height, length, radius, or width; and have something that is changing like area, distance, or volume. In order to solve related rates problems you need to be able to recall or have access to basic geometry formulas like circle, cone, cylinder, rectangle, triangle and…

5. DESCRIBE the difference between logistic growth and exponential growth. How do they look when graphed? Give EXAMPLES of natural situations where you would see each. ANSWER: An exponential model demonstrates the growth rate And how it is increasing in the population over time. The logistic model does this as well but it will eventually reach a carrying capacity or limit of the population growth. A natural situation for the exponential model is the growth of trees in a given area and an…

The cosine was developed as the sine of the complement of the angle, and notation for cosine was also varied. The term sinus residuae was used by Viete while Gunter preferred co-sinus in the year 1620. Cavalieri used Si.2, Oughtred used s co arc and Wallis used S [2]. The tangent and cotangent developed out of the need to calculate the height of an object casting a shadow of a certain length, which was of critical importance for the sundial. Thales is known to have used the method of lengths of…

thinking, I have chosen to examine my video from 2:45 – 3:25. During this time, I asked students for their answers to the problem given to them and their reasoning for this answer. In essence, I was hoping to target students’ knowledge of inverse functions and how they applied it to solving a situational problem. More specifically, if they were able to find the error in a solution of an inverse algebraic problem and explain their reasoning for this error. Moreover, once a student was able to…

For this curriculum study, I chose third grade mathematics as my unit of study. As far as my objectives go, I would want my students to walk away from this particular section of fractions with the understanding of what a fraction is, the difference between the components of a fraction such as the numerator and denominator, knowing how to identify how many parts of a whole are shaded in, and knowing how to simplify a fraction. As far as my instructional method, I created an original prezi, which…

allowed us to construct a national income model. We used figures for 2014. UK National Income model approximations The variables we need include: • A consumption function, C = a + b(Y-T) • An import demand function, M = k + mY • Exogenous variables, representing investment, I*, exports, X*, government expenditure, G* • A tax revenue function, T = tY + T* • Equilibrium condition for Y National income in the uk In 2014 the GDP in the UK came to $2522.26 Billion. We will use this…

It is important in children’s cognitive development and with their success in school. Executive functions are used to organize and act on information. Working memory is one executive function. This skill is the ability to carry information in mind for the purpose of completing a task. Working memory is like your mental sticky note. When I was in fifth grade my classmates and I were learning how…

In 1540, a man by the name of Lodovico Ferrari, please be aware that I don’t think his name has anything to do with the sports car, was an Italian mathematician known for discovering the solutions to quartic functions. A quartic function is a function of the form ax^4 + bx^3 +cx^2 +dx+e, where a is a nonzero, which is defined by a polynomial raised to the fourth degree, called quartic polynomial. We will probably go more in depth about these quartic polynomials soon in class. My quartic…

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…

people with type 2 diabetes to adhere with their treatment plan to improve diabetes care as measured by serial HbA1c measurements over an 18 month study period. This study was particularly notable because it also used other endpoints such as renal function (assessed by estimated glomerular filtration rate and urinary albumin to creatinine ratio), the lipid profile, (assessed by total, HDL and LDL cholesterol and triglyceride levels), and other indices such as blood pressure, waist…
