Question

1. This equation M(x,y)=61+0.6x-0.1y gives the mileage (in mpg) I have a new car as a function of tire pressure x (in psi) and speed y (in mph). find M(30,47) (include the appropriate units) and explain what it means.

2. This equation M(x,y) 61+0.1x-0.4y gives the mileage (in mpg) I have a new car as a function of tire pressure x (in psi) and speed y (in mph). Find Mx(29,44) (include the appropriate units) and explain what it means.

Find 14,30,47) (include the appropriate units) and explain what it mean M[30.47) (1) (Type an integer or a decimal.) Explain what the answer in the previous step means. Select the correct choice below and fill in the answer boxes within your choice. (Type integers or decimals) OA Increasing the speed by one mph and maintaining a tre pressure of psi will increase mileage by OB. Mieage is mpg at a tire pressure of psl and a speed of mph C. Increasing the tire pressure by one psi and maintaining a speed of pel wil decrease meage by D. Increasing the speed by one mph and maintaining a tire pressure of pal wil increase mileage by O E. Increasing the tre pressure by one poi and maintaining a speed of mph will increase mileage by mpg mpo mpg mpg O paper mo (1) Ompo per al Omph per poi O psi por mph Omph mpg O mpg per mph Omph por mpg Opel

Answer 1

> Given x= 30 psi y = 47 mph Mix,y) 2 61 +0.64 -0.ty M (30,47) -61 +0.6x30 -0.1X47 - 74-31 mpg since milage is calculated in mpg. It B. Milage is 74.3 mpg ata pressure of 30 psi and a speed of 47 mph. means, tire 27 Given X2 29 psi 9 44 mph M (x,y) - 61+0.18-0.44 Malny) da (61+0.12 -0.44) = 0.1 :: Mac (29,44) Impg per psi 20:1 It means, tire pressure D. Increasing the by one psi and maintaining a speed of 1941 mph will inerease milage by 0:ll mpg.
