What is Nature of the zeros of a quadratic function?
If you have a quadratic function with real coefficients then it can have: two distinct real roots, or a real double root (two coincidental roots), or no real roots. In the last case, it has two complex roots which are conjugates of one another.
How do you find the area of rectangle using function?
The area is the length times the width. That's the function. If you want to write a function in a computer language, you need two parameters. Just return the product of the two parameters. Example in Java: double rectangle_area(double length, double width) { return length * width; } I didn't test this, but that's the basic idea.
How do you tell if an equation is a function?
Let's assume (for simplicity) that "y" is a function of "x". That means that for every value of "x", there is a unique value of "y". In this case, if the equation can be solved for "y", it is a function. Some equations are difficult or impossible to solve explicitly for "y"; in this case, "y" may still be a function of "x", if for every value of "x" only a single value of "y" is possible for the equation. However, if this is the case, it may be difficult to verify.
Why a function can have at most one y-intercept?
Assuming that y is a function of x, that follows from the definition of a function. For each x-value, there can only be one y-value. The definition of a function is that (in this case), for every value of "x", a value of "y" can be calculated unambiguously. In the more general case, for every combination of the independent variables, a single value for the dependent variable can be calculated unambiguously.
What is a double insulated case?
A double insulated case is a protective covering for electronic devices that provides an extra layer of insulation to prevent electrical shock or short circuits. It typically consists of two layers of insulating material to reduce the risk of electric shock in case of a fault.
Which is better double insulated or grounded?
It is best to use both, then usually grounded, then double insulated is just OK.
Is there a symbol to identify a double insulated power tool?
A double insulated tool will have a picture of a box with a second box inside.
Are double Insulated portable tools earthed?
No.
What is the function of an insulated cup?
An insulated cup helps maintain the temperature of a beverage by reducing heat transfer through its double-wall construction or vacuum insulation. This helps keep drinks hot or cold for longer periods of time compared to a regular cup.
Characteristics of the modern chefs coat?
Double insulated reversible button front, wrinkle free, thermometer pocket, sleeve pocket, double insulated cuffs
What is the Difference between air insulated substation and gas insulated substation?
Air insulated substation means air acts as the dielectric medium but in case of gas insulated substation SF6 is the dielectric medium. Gas insulated substations are having more advantages than air insulated substations.
Can you name an appliance which are double insulated?
A common example of a double insulated appliance is an electric kettle. These appliances have an additional layer of insulation to prevent the user from being shocked if there is a short circuit within the device.
