Which of these polygons has congruent diagonals but not perpendicular?
It is not possible to answer the question since there are no polygons "following".
Use of polynomial in daily life?
Chemists use quadratic polynomials constantly in equilibrium calculations. To find unknown concentrations in reactions of that nature. The problem reduces to a polynomial that is solved by the quadratic equation. Simplified answer, Using polynomials it will soon be possible to identify some powerful techniques for seeking out the local extrema of functions, these points or bumps are often very interesting.
Is a line with undefined slope the graph of a function?
This is not a function. To be a function, there must be a one to one relationship between the independent variable (usually represented by the horizontal or x axis) and the dependent variable (usually represented by the vertical or y axis). A line with undefined slope is a vertical line, so there are an infinite number of possibilities for y and only one possible value of x, so this is not a function.
What are the possible lengths and widths if the area is 40?
Call the width x and the height y. Then expressing the area in function of x and y gives: x*y=40 or y=40/x It is now possible to choose any width (x) and calculate the height (y) needed to get an area of 40.
How do you find sides of a rectangle if you know the area and perimeter?
We know:2(w+h)=pw*h=aTherefore:w=a/h2(a/h + h)=p2(a + h^2)=p*h2*h^2 - p*h + 2a = 0which can be solved for h using the quadratic formula (see http://en.wikipedia.org/wiki/Quadratic_equation):(-b +/- sqrt(b^2 - 4ac)) / 2aTherefore:h=(p +/- sqrt(p^2 - 16a)) / 2aOnce we have h, we can get w easily by calculating a/h. Note that there may be two possible values for h (because of the +/- in the quadratic formula), so there may be two values of w to correspond with each of these.
The graph of a a certain quadratic function has no x-intercepts. Which of the following are possible values for the discriminant check all that apply. (APEX)?
-7,-25
How do you know whether it is possible to factorise a quadratic expression?
Look in an advanced maths book.Improved answer:-If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.
What is the value of the discriminant for the quadratic equation 2x2-x 80?
The browser that is used for submitting questions does not permit many mathematical symbols. It is therefore not possible to be sure what the question was. Here, it is not possible to tell whether the last term is positive or negative. For a quadratic equation of the form ax^2 + bx + c = 0, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.
Is the graph of a quadratic function contains the point 0 0?
Some do and some don't. It's possible but not necessary.
What are the possible values of k in the quadratic equation x squared plus 5kx plus 2k equals 0 which has equal real roots?
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
Is it possible for the graph of a quadratic function to have two y-intercepts?
Yes. A quadratic function can have 0, 1, or 2 x-intercepts, and 0, 1, or 2 y-intercepts.
What is the discriminant D of the equation?
The browser that is used for submitting questions does not permit many mathematical symbols. It is therefore not possible to be sure what the question was. For a quadratic equation of the form ax^2 + bx + c = 0, where a, b and c are real numbers and a is non-zero, the discriminant, D = b^2 – 4ac.
What is the discriminant of 3x2 6x 2?
The browser that is used for submitting questions does not permit many mathematical symbols. It is therefore not possible to be sure what the question was. For a quadratic equation of the form y = ax^2 + bx + c, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.
What is the discriminant 4x2 16x 16?
The browser that is used for submitting questions does not permit many mathematical symbols. It is therefore not possible to be sure what the question is. For a quadratic equation of the form y = ax^2 + bx + c, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.
What is the discriminant of 4x2 6x-5?
The browser that is used for submitting questions does not permit many mathematical symbols. It is therefore not possible to be sure what the question was. For a quadratic equation of the form y = ax^2 + bx + c, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.
Is it possible to have different quadratic equations with the same solution Why?
Yes it is possible. The solutions for a quadratic equation are the points where the function's graph touch the x-axis. There could be 2 places to that even if the graph looks different.
What is the discriminant value in 4x2 6x 5?
The browser that is used for submitting questions does not permit many mathematical symbols. It is therefore not possible to be sure what the question was. For a quadratic equation of the form y = ax^2 + bx + c, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.
