1) The sum of the square of two consecutive positive odd integers is equal to 290. Find the two integers.
So far I have (x+y)^2=290 is this right and if so where do I go from here?
2) An object is thrown downward, with an initial speed of 16 ft/s, from the top of a building 480 feet high. How many secods later will the object hit the ground? Use the equation d=vt+16t^2, where d is the distance in feet, v is the initial speed, and t is the time in seconds.
My answer is 30 sec. but all I did was divide 480 by 16 istead of use the formula. Is my answer correct and if so can someone help me do it using the formula? Thx. for help on both problems.
