A company that sells radios has yearly fixed costs of $600,000. It costs the company $45 to produce each radio. Each radio will sell for $65. The company's costs and revenue are modeled by the following functions, where represents the number of radios produced and sold:C(x)=600,000+45xR(x)=65x. This function models the company's costs This function models the company's revenue. Find and interpret (R−C)(20,000), (R−C)(30,000), and (R−C)(40000).

A plane traveling horizontally at 98 m/s over a flat ground at an elevation of m must drop an emergency packet on a target on the ground. The trajectory of the packet is given by xequals98t, yequalsminus4.9tsquaredplus3500, for tgreater than or equals0, where the origin is the point on the ground directly beneath the plane at the moment of the release. How many horizontal meters before the target should the packet be released in order to hit the target?

The conditional relative frequency table was generated using data that compared the cost of one ticket for a performance and the method by which the ticket was purchased. A 4-column table with 3 rows titled ticket purchases. The first column has no label with entries purchased online, purchased at the box office, total. The second column is labeled no more than $30 with entries 0.7, 0.3, 1.0. The third column is labeled more than $30 with entries 0.86, 0.14, 1.0. The fourth column is labeled total with entries 0.82, 0.18, 1.0. Given that Lorenzo paid more than $30 for a ticket, what is the probability that he purchased the ticket at the box office?A.0.14 B. 0.18 C. 0.30 D.0.86
