How to prove that δf(x₀,y₀,z₀) · γ'(t_0) = 0 given f(x, y,z) = x² + 4y² + 9z² and γ(t) = (x(t), y(t), z(t)) wich images is a part of the level surface x² + 4y² + 9y² = 1? (consider δf as the gradient, brain. ly does not have nabla)

angle addition postulate

2x=56

step-by-step explanation:

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
