What is q in math.
Composition of Functions. In addition to adding, subtracting, multplying and dividing, two functions can be composed. The composition of a function is when the x-value is replaced by a function. For example if p (x) = x 3 and q (x) = x - 1, the compostition of p with q is: The notation p ∘ q, reads "p composed with q".
Truth Table is used to perform logical operations in Maths. These operations comprise boolean algebra or boolean functions.

Answer: a. Explanation: If two sides of a triangle are of lengths 5 cm and 1.5 cm, then the length of the third side of the triangle cannot be 3.4 cm. Because the difference between the two sides of a triangle should be less than the third side. 18) In …This is a formula, so if you can get the right numbers, you plug them into the formula and calculate the answer (s). We always have to start with a quadratic in standard form: ax^2+bx+c=0. Making one up, 3x^2+2x-5=0, we see a=3, b=2, c=-5. I teach my students to start with the discriminant, b^2-4ac. Also, especially in the beginning, put the b ...A constant in math is a fixed value. It may be a number on its own or a letter that stands for a fixed number in an equation. For example, in the equation “6x – 4 = 8,” both 4 and 8 are constants because their values are fixed.Every rational number is the quotient of two integers.

The sum of two even integers is even and the sum of two odd integers is odd. Exercise 3.1.3. Let p = “ 2 ≤ 5 ”, q = “8 is an even integer,” and r = “11 is a prime number.”. Express the following as a statement in English and determine whether the statement is true or false: ¬p ∧ q. p → q. ben mclemore means that P and Q are equivalent. So the double implication is true if P and Q are both true or if P and Q are both false; otherwise, the double implication is false.
