# Is this statement true or false A system of linear equations is a set of two or more equations with the same variables and the graph of each equation is a line? The statement "A system of linear equations is a set of two or more equations with the same variables and the graph of each equation is a line" is true.

# What is non-examples of empire? A banana is a good non-example. Even a banana republic is not likely to be confused with an empire!

# What is an equation in slope-intercept form for the line that passes through the given point and is parallel to the given line? Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the given line (-7,3); x=4

# What is The square root of x-10 equals x-2? To find the solution to the equation √(x-10) = x-2, we can square both sides. This gives us x-10 = (x-2)^2. Expanding the right side gives x-10 = x^2 - 4x + 4. Rearranging the terms and simplifying, we have x^2 - 5x - 6 = 0. By factoring or using the quadratic formula, we can determine the solution(s) to the equation.

# How do you write exponents in WORD? To write exponents in Microsoft Word, you can use the superscript feature. Simply select the number or letter you want to raise to an exponent, go to the "Home" tab, and click on the "Superscript" button (usually represented by a small "x^2" icon). This will format the selected text as a superscript, indicating it is an exponent.

# How are linear equations similar or different from functions? A linear equation is a specific type of function that represents a straight line on a graph. While all linear equations are functions, not all functions are linear equations. Functions can take many forms, including non-linear ones that do not result in a straight line on a graph. Linear equations, on the other hand, follow a specific form (y = mx + b) where the x variable has a coefficient and the equation represents a straight line.

# What is 7.82 plus 31.23? 7.82 plus 31.23 is equal to 39.05.

# What is 8.2 divide by 10? 8.2

# What are small red dot like spiders that are found in large numbers? Let's see, if these spiders are around plants, my guess is that they are spider mites. Damage from these little guys can be severe. Leaves turn silver, as the chlorophyll disappears, or turn yellow as they die. Leaves fall on the floor for no apperant reason. A slight red dust can be found on the underside of leaves. I have never dealt with this problem, I bet a nusery worker would know how to get rid of them. Rinsing your plants every now and then can detour many pests and diseases.

# Worlds most expensive college? Technical university In russia. It costs 83,125 thousand U.S dollars.

# What is a radical equation? They are actually to the one half power. You can take a factor in the radical and sqrt it and put in on the outside...

Ex.

sqrt(28) = sqrt(4 * 7) = sqrt(22 * 7) = 2sqrt(7)

sqrt(28) = 2 * sqrt(7)

# What are the practical applications of logarithms in the field of engineering science business and economics? Logarithms were originally used to convert multiplications into additions and divisions into subtractions (plus some looking up in tables).

To multiply 3456 by 6789

1. Look up in table: log(3456) = 3.5386
2. Look up in table: log(6789) = 3.8318
3. add them together = 7.3704
4. Look up in table: antilog(7.3704) = 107.3704 = 23460000

So the only calculation is a simple addition at step 3.

Logarithms were often used for approximate calculations (4 significant figures), but there were tables for more accurate work.

Nowadays, though, it is easier to use calculators for multiplication and division.

There is a whole class of problems where the solution involves logarithms. If the rate of change in a variable X is directly proportional to the quantity X, then the solution involves logarithms (or its inverse, exponents). Typical textbook examples include radioactive decay, simple chemical reactions, bacterial {or any uncontrolled] growth, compound interest.

# How is tin used in everyday life? Tin is used to coat metals to prevent corrosion (tin cans are made from tin coated steel).

Tin is also an alloying agent. Important tin alloys such as soft solder, type metal, fusible metal, pewter, bronze, bell metal, babbitt metal, white metal, die casting alloy, and phosphor bronze.

The Pilkington Process is used for producing glass; this involves floating molten glass on molten tin to produce a flat surface.

Tin salts are sprayed onto glass to produce electrically conductive coatings. These salt treated panes can be used for panel lighting and for frost-free windshields.

Some magnets are made of crystalline tin-niobium wire, which is super conductive at low temperatures. These magnets weigh just a few pounds; yet produce magnetic fields comparable to those of 100-ton electromagnets.

# What is the output variable of a function? It is a value in the co-domain [range] of the function.

# What types of math are used in chemical engineering? Chemical engineers use Optimization Techniques and Operations Research to optimize and bring out the most suitable design with appropriate parameters.

Chemical engineers use Computational Fluid Dynamics involving lots of complex calculus to solve complicated fluid system and heat transfer problems.

Chemical engineers fit data for accurate graphical analysis using methods of regression and other graph techniques.

Chemical engineers use Partial Differential Equations and Ordinary Differential Equations using either manually or by Polymath, Matlab, Wolfram Mathematica to solve and get a solution to system of equations.

Chemical engineers use Numerical Analysis and techniques to solve a variety of problems based on the dynamic nature of the system.

Chemical engineers use Surface Volume, Area, 3-D geometry and vector algebra for material analysis and assessing physical parameters to plant systems and units.

# What are fundamental units? Fundamental unitsFundamental units, or base units, are those that cannot be decomposed into more basic units. (Note that "basic" does not mean "smaller.") Derived units, on the other hand, are those that are defined in terms of other units, which may be base units or other derived units.

In the SI system, the base unit of length is the meter, the base unit of mass is the kilogram, and the base unit of time is the second. The base unit of electrical current is the ampere which is defined in terms of the force between parallel, current-carrying conductors.

One of a set of unrelated units of measurement, which are arbitrarily defined and from which other units are derived. For example, in the SI system the fundamental units are the meter, kilogram, and second.

# What math used in Mechanical Engineering? First off, the question should be either "What math is used in Mechanical Engineering? or What is the highest level of math someone needs to take in order to become a Mechanical Engineer?"

Most college programs require through Differential Equations to earn a BS degree in ME. This means you would need to take Calculus 1, 2, and 3, Linear Algebra, and Differential Equations once you get to college. It is assumed that most students going into engineering will have no less than Pre-Calculus before entering college while most will have taken Calculus. Now each college has different requirements for fulfilling the math requirements for an engineering program. I know from my experience, Georgia Tech teaches math differently than most colleges because they combine Calc 1-3 and Linear Algebra into just 3 courses instead of 4.

My suggestion is look at the program requirements at the school you are interested in first. Second, evaluate whether you feel that you can learn the math. For those who struggle with math, if you really want to be an engineer, I suggest going to a smaller school where the class size will be smaller. This will have better student/teacher interaction so you can get more help.

# What is an non-example of light? A banana is a very good non-example.

# What is numbers that multiplies to get -48 but adds up to get 32? wouldn't it be 16 because 16 x 3 = 48 and 16+16=32Yup that would be the answer

# What is value curve? A Value Curve was first used by Accor, a French hotel chain in 1985. Value Curves were first described in a paper authored by W Chan Kim and Renee Mauborgne entitled, "Value Innovation: The Strategic Logic of High Growth," published in HBR in January, 1997. This paper has generated more reprints for HBR than any other paper published in HBR in the 1990's.

Value curves have been popularized in Kim and Mauborgne's "best selling" book, "Blue Ocean Strategy," HBS Press, March 2005.

A Value Curve is divided into two halves. On the left side are the Elements of Performamce. These Elements, in aggregate, define the product or service. On the right side of the curve is the value delivered to the most important customer for each of these Elements.

Value Curves with metrics are an elegantly simple way (one ppt slide) of describing project goals to project team members, stakeholders and senior management.
