A stunt motorcyclist makes a jump from one ramp 20 feet off the ground to another ramp 20 feet off the ground. The jump
between the ramps can be modeled by y = -,
+ 20 where is the
640
horizontal distance (in feet and y is the height above the ground on feet),

a. What is the motorcycle's height r when it lands on the ramp?
b. What is the distance d between the ramps
c. What is the horizontal distance h the motorcycle has traveled when it
reaches its maximum height?
d. What is the motorcycle's maximum height k above the ground?

Need ! discuss how to convert the standard form of the equation of a circle to the general form. 50 points

Simplify the following expression 48^1/2

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
