We are given

Firstly, we can find gradient
so, we will find partial derivatives





now, we can plug point (-5,5,2)



so, gradient will be

now, we are given that
it is in direction of v=⟨−3,2,−4⟩
so, we will find it's unit vector


now, we can find unit vector

now, we can find dot product to find direction of the vector

now, we can plug values

Answer:
5/4
Step-by-step explanation:
Answer:
See solution below
Step-by-step explanation:
According to the diagram shown
m<1 = m<5 = 5=65 degrees (corresponding angle)
m<5 = m<4 - 65 degrees (alternate interior angle)
m<9 = m<8 = 65degrees (corresponding angle)
m<5 = m<8 = 65dgrees (vertically opposite angles)
m<6+m<8 = 180
m<6 + 65 = 180
m<6 = 180 - 65
m<6 = 115degrees
m<2 = m<6 = 115degrees (corresponding angles)
m<6 = m<7 = 115degrees (vertically opposite angles)
m<3 = m<7 = 115degrees(corresponding angle)

If I understand your question correctly then it's simple all you have to do is use the numbers in the place of the b and c so the question would be what is 8-7 which equals 1
I don't have an idea of what the answer is to be honest.
