Which property is illustrated by the statement (4+6.1)+7=4+(6.1+7)

Slav-nsk [51]

Answer: It is an associative property of addition.

Step-by-step explanation:

Since we have given that

(4+6.1)+7=4+(6.1+7)

As we know that "Associative property":

$(a+b)+c=a+(b+c)$

Associativity in addition means that adding three numbers and then change the order of numbers and then add it again, we will get the same answer.

So,

$(4+6.1)+7=10.1+7=17.1\\\\Similarly,\\\\4+(6.1+7)=4+13.1=17.1$

Hence, it is an associative property of addition.

Let u = e^qr sin-1p, p = sinx, q = z²ln y, r = 1 / z. Find the derivatives au / ax, au / ay, and au / az as a function of x y an

Reil [10]

Step-by-step explanation:

$u = {e}^{qr} \sin {}^{ - 1} (p) \\ \sin u = {e}^{qr} \sin \: x \\ \cos u \: au = \cos x \: ax \\ \frac{au}{ax} = \frac{ \cos(x) }{ \cos(u) }$

$u = {e}^{qr} { \sin }^{ - 1} (p) \\ u = {e}^{ {z}^{2} ln(y) . \frac{1}{z} } { \sin }^{ - 1} (p) \\ u = {e}^{z ln(y) } { \sin }^{ - 1} (p) \\ \sin(u) = {e}^{z ln(y) } .p \\ ln( \sin(u) ) = z ln(y) \\ \frac{ \cos(u) }{ \sin(u) } au = \frac{z}{y} ay \\ \frac{au}{ay} = \frac{z \sin(u) }{y \cos(u) } \\ \frac{au}{ay} = \frac{z \tan(u) }{y}$

au/az is got from the same expression.
