Let f be a function of two variables that has continuous partial derivatives and consider the points A(6, 4), B(7, 4), C(6, 10), and D(18, 13). The directional derivative of f at A in the direction of the vector AB is 5 and the directional derivative at A in the direction of AC is 5. Find the directional derivative of f at A in the direction of the vector AD. (Round your answer to two decimal places.)

Iam stuck on one problem. my mind is in absoloute vacation mode. i literallty just need to finish this to be done will give brainliest and all my points if i have to! 1- point free throw and 2- point feild goal. he made 35 shots, and scored 62 points how many of each shot did he make in 1 minute? (i already did the math. he made 8 1-point free throws and 27 2-point feild goals.) 1. write two equations for the problem. (i had a major brain fart.)

Brent works part-time at a clothing store. he earns an hourly wage of $15. if he needs to earn more than $45 in a day and works for x hours a day, which inequality represents this situation? a. 15x > 45 b. 15x < 60 c. x > 60 d. 15x < 45 e. x < 60

Can someone answer it, and plot it, for 20 points and brainliest answer? p.s. they're the same ! : )
