IRINA_888 [86]

Answer:

1 : 3

Step-by-step explanation:

Given the following :

First day :

Patient received = 24

Patient discharged = 6

Second day :

Patient received = 8

Patient discharged = 21

First day :

Patient received = 9

Patient discharged = 6

Number of patient in the hospital at the end of the third day:

Patients received = (24 + 8 + 9) = 41

Patients discharged = (6 + 21 + 6) = 33

Patient received - patient discharged

= (41 - 33) = 8

Number of patients in hospital at the start of the three day period :

Patient received on first day = 24

Patient at the end : patient at the start

8 : 24 = 1 : 3

If xy + y² = 6, then the value of dy/dx at x= -1 is<br>​
mylen [45]

Hi there!

\large\boxed{\text{At (-1, -2), }\frac{dy}{dx} = -\frac{2}{5}}}

\large\boxed{\text{At (-1, 3), }\frac{dy}{dx} = -\frac{3}{5}}}

We can calculate dy/dx using implicit differentiation:

xy + y² = 6

Differentiate both sides. Remember to use the Product Rule for the "xy" term:

(1)y + x(dy/dx)  + 2y(dy/dx) = 0

Move y to the opposite side:

x(dy/dx) + 2y(dy/dx) = -y

Factor out dy/dx:

dy/dx(x + 2y) = -y

Divide both sides by x + 2y:

dy/dx = -y/x + 2y

We need both x and y to find dy/dx, so plug in the given value of x into the original equation:

-1(y) + y² = 6

-y + y² = 6

y² - y - 6 = 0

(y - 3)(y + 2) = 0

Thus, y = -2 and 3.

We can calculate dy/dx at each point:

At y = -2: dy/dx = -(-2) / -1+ 2(-2) = -2/5.

At y = 3: dy/dx = -(3) / -1 + 2(3) = -3/5.
