Unformatted text preview: The only possible value for d is 6. All values for d other than 4, 5, 6 and 7 yield negative answers and only 6 produces integer answers. Therefore there are 3 pennies, 4 nickels and 6 dimes. 4) Use a system of equations to find the equation of the parabola, y = ax 2 + bx + c , passing through the points (0, 2), (-3, -1) and (0.5, 0.75). There are three equations generated by plugging the three points into the quadratic. c = 2 9a 3b + c = -1 0.25a + 0.5b + c = 0.75 The solution to the system is , so is the equation of the parabola. 5) Describe the solution set of the system below as a linear combination of 3 vectors. 6) Let and . All linear combinations of u and v are solutions to some system of equations. Find that system....
