A golfer hits a ball from a starting elevation of 2 feet with a velocity of 70 feet per second down to a green with an elevation of −7 feet. The number of seconds t it takes the ball to hit the green can be represented by the equation −16t2 + 70t + 2 = −7. How long does it take the ball to land on the green?

Let us imagine that the number of automobile accidents in a certain region are related to the regional number of registered automobiles in tens of thousands (b1), alcoholic beverage sales in $10,000 (b2), and decrease in the price of gasoline in cents (b3). furthermore, imagine that the regression formula has been calculated as: y = a + b1x1 + b2x2 + b3x3 where y = the number of automobile accidents, a = 7.5, b1 = 3.5, b2 = 4.5, and b3 = 2.5 calculate the expected number of automobile accidents for a football weekend if the region has 25,000 registered vehicles, $75,000 worth of beer is sold, and a gas war causes a 10 cent drop in a gallon of gas.
