Therefore, the discriminant of the equation x^2 - 3x - 7 is (-3)^2 - 4(1)(-7) = 9 + 28 = 37.

Option B:

The discriminant of the quadratic equation 3x^2 - 5x + 4 is the value of b^2 - 4ac, which is (5)^2 - 4(3)(4) = 25 - 48 = -23. A negative discriminant (-23) would indicate that the equation has no real solutions, meaning it has no solutions in real numbers.

The three types of loops that can be built using the while statement and other statements are The While Loop,The For Loop,The Do-While Loop.

Loop in math is a path or line that starts and ends at the same point. It can refer to a continuous curve, like a circle, or to a sequence of discrete points, like a polygonal line. It is a fundamental concept in mathematics, used to study various topics such as curves, surfaces, and solids. Loops are also used in graph theory to study networks.

Yes, it is possible to form a triangle with sides of 3.5cm, 4.5cm, and 7.5cm. This is because these triangle's sides adhere to the triangle inequality theorem.

The triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. This is because in order to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side, otherwise it would be impossible to connect the three sides and form a closed shape.

In this case,

3.5 cm + 4.5 cm = 8 cm > 7.5 cm

3.5 cm + 7.5 cm = 11 cm > 4.5 cm

4.5 cm + 7.5 cm = 12 cm > 3.5 cm

So it is possible to form a triangle with these side lengths.

The end behavior of a function is the way the graph of the function behaves as either x→∞ or x→−∞.

To calculate the end behavior of a function, we take the highest degree of the function and look at the leading coefficient. If the leading coefficient is positive, then the graph will go to positive infinity as x→∞ and will go to negative infinity as x→−∞. If the leading coefficient is negative, then the graph will go to negative infinity as x→∞ and will go to positive infinity as x→−∞. For example, if the function is f(x) = 2x^3 + 6x, then the highest power is 3 and the leading coefficient is 2, which is positive. Therefore, the graph of the function will go to positive infinity as x→∞ and will go to negative infinity as x→−∞.

The slope of the given linear equation y = 2x + 10 is 2.

If we draw the graph of the linear equation y = mx + c. The result is a line with m as the slope, and c as the y-intercept. This form of the linear equation y = mx + c is called the slope-intercept form, and the values of m and c are real numbers.

The slope, m, of the line represents the steepness of a line. This is also termed a gradient, sometimes. The y-intercept, c, of the line y = mx + c represents the y-coordinate of the point where the graph of the line intersects the y-axis.

Now, if we equate the standard slope-intercept form of the equation with the given equation, we get

y = mx + c

The measures of angles m∠ABC = 36° and m∠CBD = 84°.

Geometry is a branch of mathematics that deals with shapes, sizes, angles, and dimensions of objects.

The angle m∠ABD = 120° is the result for the sum of the two angles m∠ABC and m∠CBD so;

m∠ABC + m∠CBD = m∠ABD

2x + 5x - 6 = 120°

7x - 6 = 120° {add 6 to both sides}

7x = 120° + 6°

7x = 126° {divide through by 7}

x = 126°/7

x = 18

2x = 2(18) = 36°

The triangle formed by sides 24, 25 and 5 cm is not a right angled triangle.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Let us consider the triangle is a right angle triangle

An unbounded problem is one for which the objective can be increased or decreased to infinity or negative infinity while the solution remains feasible. This means that the problem has no finite upper or lower limit and is not subject to any specific constraints. As a result, there may be more than one combination of decision variables that will maximize or minimize the objective. In addition, there may not be exactly one solution that will result in the maximum or minimum objective value, as the solution set can be infinite.
