Okay, let's think through this with the new information:
* The equation modeling the height is: h = -16t^2 + vt + c
* The initial height (c) is still 2 feet
* The initial velocity (v) is now 20 feet/second
* The target height (h) is still 20 feet
So the equation is:
20 = -16t^2 + 20t + 2
0 = -16t^2 + 20t + 18 (subtract 20 from both sides)
Evaluating the discriminant:
(20)^2 - 4(-16)(-18) = 400 - 288 = 112
Since the discriminant is positive
There are three possible outcomes when graphing two linear equations:
1) A single point of intersection, meaning one solution.
2) Parallel lines, meaning no solution.
3) Coincident lines with the same slope and y-intercept, meaning an infinite number of solutions.
The type of solution can be determined without graphing by writing the equations in slope-intercept form and comparing slopes and y-intercepts. Different slopes means one solution, same slope but different intercepts means no solution, and same slope and intercept means infinite solutions.

Adding and subtracting rational expressionsDawn Adams2
Using rules for fractions, rational expressions can be added and subtracted by finding common denominators. To find the common denominator, we find the least common multiple (LCM) of the denominators. With polynomials, the LCM will contain all factors of each denominator. We can then convert the fractions to equivalent forms using the LCM as the new denominator before combining like terms to evaluate the expression. Special cases may involve fractions with understood denominators of 1 or similar but non-equal denominators that can be made equal through factoring.
In algebra, polynomial long division is an algorithm for dividing a polynomial by another polynomial of the same or lower degree, a generalized version of the familiar arithmetic technique called long division. It can be done easily by hand, because it separates an otherwise complex division problem into smaller ones.
In algebra, the synthetic division is a method for manually performing Euclidean division of polynomials, with less writing and fewer calculations than the long division. It is mostly taught for division by linear monic polynomials, but the method can be generalized to division by any polynomial.

The objectives are to determine appropriate factoring methods, factor polynomials completely using various techniques, and solve problems involving polynomial factors.
1) A surd is a number whose square root is not a whole number. Common surds include √2, √3, √5.
2) Surds can be simplified by breaking numbers into factors where one is a perfect square.
3) Surds can be added, subtracted, multiplied, or divided following specific rules such as having the same basic form or multiplying by conjugates.
This document introduces methods for solving quadratic equations beyond factoring, including the square root property, completing the square, and the quadratic formula. It discusses how to determine the number and type of solutions based on the discriminant. The key steps are presented for solving quadratics, graphing quadratic functions as parabolas, and finding the domain and range. Piecewise-defined quadratic functions are also explained.
Adding and subtracting radicals ppt white board practicetty16922
This document contains a series of practice problems for adding and subtracting radical expressions. It provides the problems, step-by-step workings, and answers. There are 18 questions in total covering topics like combining like terms under a single radical, simplifying radicals, and identifying errors in working problems. The document emphasizes studying for an upcoming quiz on radicals.
The document discusses using the order of operations to evaluate expressions. It provides the mnemonic "Please Excuse My Dear Aunt Sally" (PEMDAS) to remember the order: Parentheses, Exponents, Multiply/Divide (left to right), Add/Subtract (left to right). Several examples are worked through step-by-step to demonstrate evaluating expressions according to this order. The document also covers evaluating expressions when variables are substituted with values.
Solving quadratic equation using completing the squareMartinGeraldine
1. The document provides steps for solving quadratic equations using completing the square. It involves isolating terms with x, finding the square of half the coefficient of x, completing the square of the left side of the equation, applying the square root property, and solving for the roots.
2. Three examples are shown applying these steps: finding the solution set of x^2 - 18x = -17 to be x = 17 and x = 1; solving x^2 + 10x - 11 = 0 to get x = 1 and x = -11; and solving x^2 = -24 + 10x to get x = 6 and x = 4.
The document provides information about an online math class, including:
- A prayer asking God for guidance and wisdom as students wait to be taught.
- Reminders for online class such as turning on cameras, being on time, muting/unmuting audio.
- The weekly task of answering pretest questions from the module.
- An overview of the math topic for the first week of quarter 1 - quadratic equations. It discusses methods for solving quadratic equations such as extracting square roots, factoring, completing the square, and using the quadratic formula.

The document provides examples and explanations for solving different types of equations, including:
1) Polynomial equations through factoring or the quadratic formula.
2) Rational equations by clearing denominators.
3) Radical equations by squaring both sides to remove radicals.
4) Absolute value equations by recognizing that |x-c|=r implies x=c±r.
The document also discusses solving power equations, finding zeros and domains of functions, and using properties of absolute values.
1) The document provides examples and formulas for calculating square roots and cube roots. It gives the definitions of square roots and cube roots and shows how to evaluate them using prime factorizations or long division methods.
2) Several word problems are worked out step-by-step to demonstrate how to find the square root or cube root of various numbers.
3) Formulas are provided for operations involving square roots, such as multiplying or dividing them.
This document discusses solving nonlinear systems of equations in three ways: elimination, substitution, and graphing. It provides examples of solving systems by each method and discusses key steps like eliminating variables, substituting values, and finding the intersection point(s) of graphs. Absolute value equations are also addressed. Students are expected to be able to solve nonlinear systems by any method, as questions may require non-graphical solutions for irrational answers. A classwork and quiz assignment is provided to practice these skills.
