The largest 4 digit number is 9999
True. The largest 4-digit number is 9999. Any number higher (10,000 and above) requires five digits, making 9999 the maximum value possible in the thousands place.

A triangle is a three-dimensional shape
False.
A triangle is a two-dimensional (2D) shape, not a three-dimensional (3D) shape. It is a flat, plane polygon with three sides and three angles that only possesses length and width, but no depth. Examples of 3D shapes that use triangles in their structure include pyramids and tetrahedrons.

An equilateral triangle has only two of its sides equal. True or false?
False
An equilateral triangle is defined by having all three sides equal in length, not just two. While it is technically a special type of isosceles triangle (which must have at least two sides equal), the defining characteristic of an equilateral triangle is that all three sides are congruent.

Find the derivative of
f(x) =3x⁴-5x²+7
f(x) =3x⁴-5x²+7
First term
d/dx (3x⁴) = 4(3)x⁴¯¹
= 12x³
Second term
d/dx (5x²) = 2(5)x²¯¹
10x
Third term is a constant
Therefore, d/dx (7)=0
Final answer
12x³-10x

MOST IMPORTANT FORMULAS
The image displays the limit definition of the derivative, a fundamental concept in calculus.
The formula, is used to find the instantaneous rate of change of a function f(x) at any point x. It represents the slope of the tangent line to the curve of the function at that specific point. This specific definition, often taught as differentiation from first principles, was formalized by the French mathematician Augustin-Louis Cauchy.

If two lines are perpendicular, the product of their slopes is 1.
The statement is False;
if two non-vertical lines are perpendicular, the product of their slopes is -1.
Explanation
For two lines to be perpendicular, their slopes must be negative reciprocals of each other. If we denote the slope of the first line as m1 and the slope of the second line as m2,the relationship is defined by the formula:
m1 × m2 = - 1

Using Cramer’s Rule to solve simultaneous equation, you get different answer when using elimination method provided the questions are same.
False
Using Cramer’s Rule and the elimination method to solve the same system of linear equations will yield the same answer, assuming the system has a unique solution. Both methods are valid mathematical techniques for finding the unique intersection point of linear equations. Both methods are designed to solve the same, unique, linear systems.
While elimination is often more computationally efficient, both methods are mathematically equivalent.
Note: Differences in answers usually only occur if there is a calculation error, such as a mistake in finding determinants in Cramer's rule or a sign error during elimination.
