The quantity \(x\) of satellite radios that a manufacturer will make available in the marketplace is related to the unit price \(p\) (in dollars) by the equation $$ p=\frac{1}{10} \sqrt{x}+10 $$ How many satellite radios will the manufacturer make available in the marketplace if the unit price is \(\$ 30\) ?
Use the discriminant to determine the number of real solutions of the equation. $$ 3 y^{2}-4 y+5=0 $$
The diameter \(x\) (in inches) of a batch of ball bearings manufactured by PAR Manufacturing satisfies the inequality $$ |x-0.1| \leq 0.01 $$ What is the smallest diameter a ball bearing in the batch can have? The largest diameter?
Use the discriminant to determine the number of real solutions of the equation. $$ 2 p^{2}+5 p+6=0 $$
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 \(b^{2}-4 a c \neq 0\) and \(a \neq 0\), then \(a x^{2}+b x+c=0\) has two distinct real roots, or it has no real roots at all.
