A discontinuity in mathematics is when a function is not well defined
How to identify discontinuity?As earlier defined, discontinuity deals with a function that is not well defined.
Different functions have different discontinuity depending on the function
Good examples of discontinuity include
y=1/x this is a discontinuous function.
x=0 is also a discontinuous function as it is not well defined. because there is no value for y
The function TanA is a discontinuous function because it is not well defined.

D.
The centroid will be inside, on, or outside the
scalene triangle, depending on whether it is
acute, right, or obtuse, respectively. The
number of congruent sides does not affect
the location of the centroid.
The relationship between a scalene triangle and the location of its centroid is; A: The centroid will always be inside the scalene
triangle, since the centroid is always inside any type of triangle.
What is the location of the centroid of the triangle?A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures.
Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.
Now, a centroid of a triangle is defined as the point formed by the intersection of the medians of the triangle. Now, the medians of a triangle always lie within a triangle. This means that their intersection point which is the centroid of a triangle always lies inside a triangle.
Thus, the centroid of the scalene triangle can be concluded to always lie inside the triangle.

What are the roots of 3x² 5x 2 0?
The equation 3x² + 5x + 2 = 0 has two solutions, x = -2 and x = -1/3. This means that when the equation is set equal to zero and then solved, the two values of x that will make the equation true are -2 and -1/3.
To solve 3x² + 5x + 2 = 0, we must first find the roots of the equation. To do this, we can use the quadratic formula to solve for the two roots. The quadratic formula is x = [-b ± √(b² - 4ac)]/2a, where a, b, and c are the coefficients of the equation. To apply this to our equation, we have a = 3, b = 5, and c = 2, so the formula becomes x = [-5 ± √(5² - 4(3)(2))]/2(3). Simplifying this equation gives us x = [-5 ± √29]/6. The two solutions of this equation are x = -2 and x = -1/3. This means that when the equation is set equal to zero and then solved, the two values of x that will make the equation true are -2 and -1/3.
x = [-5 ± √29]/6
x = [-5 + √29]/6 = -2

A box is dragged without acceleration in a straight-line path across a level surface by a force of 100 n. What is the frictional force between the box and the surface?.
The frictional force between the box and the surface is 100 newtons .
Since the body being dragged across the surface is not accelerating, the acceleration of the body is 0m/s².
From Newtons second law of motion, F = ma where;
F is the sum of the forces acting on the body
m is the mass of the body
a is the acceleration
If the box is dragged along a straight line by a force of 100 N, its moving force (Fm) is 100 N and the frictional force (Ff) will act opposite to this force.
Resultant force acting on the box along the horizontal will be Fm+(-Ff)
Therefore;
Fm+(-Ff) = ma
Fm-Ff = ma
Since a = 0m/s²
Fm-Ff = m(0)
Fm-Ff = 0
Fm = Ff
This shows that for a static body, the moving force acting on the body will be the same as the frictional force. Since Fm = 100 N
Frictional force (Ff) = 100 N
Therefore, the frictional force between the box and the surface is 100 N

To find the x-intercept of a rational function we put y=0 in the given and find the corresponding value of x.To find the y-intercept of a rational function we put x=0 in the function and the value of y.
what are intercepts?The x-intercept is the point where a line crosses the x-axis.At this point y=0 and the y-intercepts is the point where a line crosses the y-axis.At this point x=0
It is point where the graph of the rational function intersects the x-axis or y-axis.
How do we find vertical and horizontal asymptotes of rational function?For Horzontal asymptotes
The horizontal asmptotes of a rational function can be determined by looking at the degree of the numerator and denominator.if Nis the degree of numerator and Dis the degree of denominator.Then N<D
So horizontal asymtote is y=0
To finding horizontal asymptotes we can just focus on degree of numerator and denominator.
For vertical asymptotes
vertical asymptotes occur where the denominator of a rational function approaches zero.A rational function cannot cross a vertical asymptotes because it would be dividing by zero. we set denomintor to zero and solve value of x.The values of x are vertical asymptotes.
Hence we can find easily horizontal and vertical asymptotes of rational function.
