Concept explainers
A ball is thrown upward and outward from a height of 6 feet. The height of the ball, f(x) in feet, can be modeled by
f(x) = – 0.8 x2 + 2.4x + 6.
where x is the ball's horizontal distance, in feel, from where it was thrown.
a. What is the maximum height of the ball and how far from where was thrown does this occur?
b. How far docs the ball travel horizontally before hitting the ground? Round lo the nearest tenth of a foot.
c. Graph the function that models the ball's parabolic path.

- A path of a toy rocket thrown upward from the ground at a rate of 208 ft/sec is modeled by the quadratic function of. h(x)=16t2+208t. When will the rocket reach its maximum height? What will be the maximum height?arrow_forwardTo put the quadratic function f(x)=ax2+bx+c in standard form, we complete the ________________.arrow_forwardSolve the following application problem. A rectangular field is to be enclosed by fencing. In addition to the enclosing fence, another fence is to divide the field into two parts, running parallel to two sides. If 1,200 feet of fencing is available, find the maximum area that can be enclosed.arrow_forward
- Assume that an object tossed vertically upward reaches a height of h feet after t seconds, where h=100t16t2. What is that maximum height?arrow_forwardWhen a certain drug is taken orally, the concentration of the drug in the patient's bloodstream After t minutes is given by C(t)=0.06t0.0002t2 where 0t240 and concentration is measured in mg/L .When is the maximum serum concentration reached, and what is that maximum concentration?arrow_forward
