Let f be a function of two variables that has continuous partial derivatives and consider the points A(2, 5), B(10, 5), C(2, 10), and D(18, 17). The directional derivative of f at A in the direction of the vector AB is 2 and the directional derivative at A in the direction of AC is 14. Find the directional derivative of f at A in the direction of the vector AD. (Round your answer to two decimal places.)

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
