Yes, it’s option one where y is neg five
The rate of change in z at (4,9) as we change x but hold y fixed is =
3/[2sqrt(3x+2y)] put x = 4 , y = 9 = 3/[2sqrt(12+18) = 3/[2sqrt(30)] The
rate of change in z at (4,9) as we change y but hold x fixed is =
1/sqrt(3x+2y) put x = 4, y =9 = 1/sqrt(30)
Why now :cccccccccccccccccc
Answer:
6 units
Step-by-step explanation:
could each square from E to D
You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
