5 REAL LIFE EXAMPLE OF DIRECT VARIATION: The more time i drive (at a contant rate)the more miles i go. If i increase a recipe for more poeple,the more of ingredient i need. The more hours i work,the more money i make. The more CD's i purchase,the more money it costs. The less cheese i buy at the dell,the less money i pay.
Direct variation: 1. The more hours you work, the more money you earn. 2. The more gallons of gasoline you purchase, the farther you can drive. 3. The more pages you read, the more knowledge you gain. 4. The more employees you hire, the greater the productivity of your business. 5. The more people attend a concert, the higher the ticket sales.
Example of a Direct Variation - 954877. ... then y=30 and x=5 the constant variation is k= 30/5 =6 thus, y=6x
What is an example of direct variation? A. xy = 10 . B. y = 2/x. C. y = 5x. D. 2/y = x . Step-by-step explanation: Some examples of direct variation problems in real life: The number of hours you work and the amount of your paycheck. The amount of weight on a spring and the distance the spring will stretch.
Some examples of direct variation formula in real life: Circumference of a Circle = 2πr where r (radius) is the independent variable and 2π is the direct variation constant. f(L) = 45L Where f(L) is the total cost of fuel, and 45 is constant
Direct Variation. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if yvaries directly as x , and y = 6 when x = 2 , the constant of variation is k = = 3 . Thus, the equation describing this direct variation is y = 3x .
We say that x and y are inversely proportional, or have inverse variation, when xy = k, a constant. So, this means that y = k/x. Whenever you increase x, y decreases. Below are some examples of real life situations involving inverse variation: 1. Number of People and Rates of Work. For example, 2 people can finish a job in 6 hours.
Direct variation examples in real life situation - 32357465. Analie was told by her mother to buy 4 pcs dried fish in the near sari-sari store.
Many individuals say that one variable “varies directly” as the other. The constant ratio is called the constant of variation. Example for DIRECT VARIATION: Some examples of direct variation problems in real life: The number of hours you work and the amount of your paycheck. The amount of weight on a spring and the distance the spring will ...
INVERSE VARIATION - A variation opposite to Direct Variation. When the variable increases, the other variable decreases and vise versa. JOINT VARIATION - A variation just like Direct Variation but has two or more variables to be variated. Like the variable is jointly variated as two or more quantities. COMBINED VARIATION
