Solve the equation. $$ \frac{2 t+1}{t-2}-\frac{t}{t+1}=-1 $$
Determine whether the statement is true or false. If it is true, explain why it is true. If it is false, explain why or give an example to show why it is false. If \(a\) and \(b\) are real numbers and \(a b \neq 0\), then \(a \neq 0\) or \(b \neq 0 .\)
Suppose \(\boldsymbol{a}\) and \(\boldsymbol{b}\) are real numbers other than 0 and \(a>b\). State whether the inequality is true or false. $$ -a<-b $$
A cyclist riding along a straight path has a speed of \(u \mathrm{ft} / \mathrm{sec}\) as she passes a tree. Accelerating at \(a \mathrm{ft} / \mathrm{sec}^{2}\), she reaches a speed of \(v \mathrm{ft} / \mathrm{sec} t\) sec later, where \(v=u t+a t^{2}\). If the cyclist was traveling at \(10 \mathrm{ft} / \mathrm{sec}\) and she began accelerating at a rate of \(4 \mathrm{ft} / \mathrm{sec}^{2}\) as she passed the tree, how long did it take her to reach a speed of \(22 \mathrm{ft} / \mathrm{sec} ?\)
Solve the equation by using the quadratic formula. $$ m^{4}-13 m^{2}+36=0 $$
