What does express in terms of mean?
It means to express the quantity you’re finding in terms of x, the variable. Idiomatically speaking, to write a function “in terms of” a given variable or variables means to write an algebraic expression using only that variable or variables.
How do you find expressions?
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
How do you express surface area?
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
How do you express surface area in terms of volume?
A: Surface area to volume ratio can be found easily for several simple shapes, like for example a cube or a sphere. For a cube, the equation for surface area is S=6*L*L, where L is the length of a side. Similarly, the volume of a cube is V =L*L*L.
How do I simplify an expression?
To simplify any algebraic expression, the following are the basic rules and steps:
- Remove any grouping symbol such as brackets and parentheses by multiplying factors.
- Use the exponent rule to remove grouping if the terms are containing exponents.
- Combine the like terms by addition or subtraction.
- Combine the constants.
How do you write an expression?
To write an expression, we often have to interpret a written phrase. For example, the phrase “6 added to some number” can be written as the expression x + 6, where the variable x represents the unknown number.
How do you simplify a problem?
Here are the basic steps to follow to simplify an algebraic expression:
- remove parentheses by multiplying factors.
- use exponent rules to remove parentheses in terms with exponents.
- combine like terms by adding coefficients.
- combine the constants.
What are examples of expressions?
The definition of an example of expression is a frequently used word or phrase or it is a way to convey your thoughts, feelings or emotions. An example of an expression is the phrase “a penny saved is a penny earned.” An example of an expression is a smile.
What expression is equivalent to 100000?
Meanwhile, the exponent of the “exponential term” of 100,000 is 5 because the decimal point in the “digit term”, 1, must be moved five times to the right to arrive at 100,000. The exponent is positive because 100,000 is greater than or equal to ten. Therefore, the expression that is equivalent to 100,000 is C..
How do you find the algebraic expression?
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
What is TSA of cylinder?
Total Surface Area of Cylinder The total surface area of a cylinder is equal to the sum of areas of all its faces. The Total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder. TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.
