Projectile Motion In Exercises 75 and 76, consider the path of an object projected horizontally with a velocity of v feet per second at a height of s feet, where the model for the path is x2=v216ys. In this model (in which air resistance is disregarded), y is the height (in feet) of the projectile and x is the horizontal distance (in feet) the projectile travels. A ball is thrown from the top of a 100-foot tower with a velocity of 28 feet per second. (a) Write an equation for the parabolic path. (b) How far does the ball travel horizontally before it strikes the ground?
The point-slope form of the equation of the line with slope 3 passing through the point 1, 2 is _.
Depreciation A small business buys a computer for 4000. After 4 years the value of the computer is expected to be 200.For accounting purposes the business uses linear depreciation to access the value of the computer at a given time. This means that if V is the value of the computer at time t, then a linear equation is used to relate V and t. a Find a linear equation that relates V and t b Sketch a graph of this linear equation. c What do the slope and v-intercept of the graph represent? d Find the depreciated value of the computer 3 years from the date of purchase.
