If <em>y</em> = cos(√<em>x</em>), then by the chain rule
d<em>y</em>/d<em>x</em> = d/d<em>x</em> [cos(√<em>x</em>)]
d<em>y</em>/d<em>x</em> = - sin(√<em>x</em>) d/d<em>x</em> [√<em>x</em>]
d<em>y</em>/d<em>x</em> = - sin(√<em>x</em>) (1 / (2√<em>x</em>))
d<em>y</em>/d<em>x</em> = - 1/2 sin(√<em>x</em>) / √<em>x</em>
Answer:
Step-by-step explanation:
Step one: 9÷1.5= 6
Step two: 3·6=18
The actual book is 18 inches tall and 9 inches wide
X= 7
This is because of you plug in 7 for x into the equation it will give you 28-10 which is 18.
7x^4 - 21x^2a^2 + x^2a^2 - 3a^4
7x^4 - 20x^2a^2 -3a^4
Answer:
Number of Ways = ₄P₄ = 24
Step-by-step explanation:
Given that there are going to be 4 dignitaries, and that they are sensitive to the order (i.e the order of the dignitaries matter), hence the total number of ways they can be arranged can be found by permutating 4 dignitaries.
i.e
Number of Ways = ₄P₄ = 24
