Answer:
The answer is 4.2 kilograms of dog food
Step-by-step explanation:
it says that ray feeds his dog 0.12 kilogram of food each day
he needs for 1 month
1 month = 31 days or 30 days
since 1 day food is 0.12 kilograms you'll have to multiply 0.12 with 1 month
i.e; 0.12*31 or 0.12*30
0.12*31=3.72 and 0.12*30=3.6
since we don't have an option we'll have to choose something bigger than this
therefore, the answer is 4.2
Yes you are correct.........
Use the cross product to find the orthogonal vector, solve the parametric equation to see at which (t) the point + orthogonal vector intersects the plane, the distance is (t) * norm of vector
F(x) = x/4
so
f(-8) = -8/4 = -2
answer
f(-8) = -2
