Write in expanded form 1) 531.029

Paraphin [41]

Answer:

expanded for everything

Step-by-step explanation:

Expanded Form of 531.029:

531.029 = (5 * 102) + (3 * 101) + (1 * 100) + (2 * 1/102) + (9 * 1/103)

531.029 = (5 * 100) + (3 * 10) + (1 * 1) + (2 * 1/100) + (9 * 1/1,000)

531.029 = 500 + 30 + 1 + 2/100 + 9/1,000

531.029 = 500 + 30 + 1 + 0.02 + 0.009

If xy + x = 12 and dx/dt = -3, then what is dy/dt when x = 2 and y = 5?

dlinn [17]

If $xy + x = 12$ , then
$\dfrac{d}{dt}(xy+x)= \dfrac{d}{dt}(12)$ .
Use the chain rule:
$y\dfrac{dx}{dt}+x \dfrac{dy}{dt}+ \dfrac{dx}{dt}=0$ ,
Since x=2, y=5, dx/dt = -3, then

$5\cdot (-3)+2\cdot \dfrac{dy}{dt}+(-3)=0, \\ 2\cdot \dfrac{dy}{dt}=18, \\ \dfrac{dy}{dt}=9$ .
