Dy/dx ln(xy)=e^(x+y)

1 answer:

4 0

In(xy) = e^(x+y)

(xy)'/xy = (x+y)' e^(x+y)

(x'y + xy')/xy = (1+y') e^(x+y)

(y + xy')/xy = (1+y')e^(x+y) and simplify

Hope this helps

two thirds of the area of a farm land was covered by wheat fields half of the remaining was covered by pound and the rest was ga

oksian1 [2.3K]

Answer:

The total area of the farm land is 2520 sq. m

Step-by-step explanation:

Let us assume the total area of the farm land = P sq. m

Now, two thirds of the area of a farm land was covered by wheat fields.

So, the area covered in Wheat field = $\frac{2}{3} \times P = (\frac{2}{3})P$

The area left which is not covered in wheat

= Total land - Land covered in Wheat

= $P - (\frac{2}{3}) P = (\frac{1}{3})P$

Also, the half of the remaining land is covered by pound.

So, the area covered in pound = $\frac{1}{2} \times (\frac{P}{3} ) = (\frac{P}{6} )$

The other half is empty garden.

⇒The area empty garden = $\frac{1}{2} \times (\frac{P}{3} ) = (\frac{P}{6} )$

Also, the area of the garden = 420 sq. m

⇒ $(\frac{P}{6}) = 420\\\implies P = 6 \times 420 = 2520$

or, P = 2520 sq. m

Hence, the total area of the farm land is 2520 sq. m

2x plus 3=7 <br><br> i really need help on this so if you could that would be really appreciative :)

Rainbow [258]

X= 2

2x+3 =7
-3. -3
Subtract 3 from both sides

2x/2= 4/2

Divide 2 by both sides

X=2

What are the solutions to 6(x - 5) = 12 and 6y - 5 = 12?

zepelin [54]

Answer:x=7

y=2 5/6

Step-by-step explanation:

6(x-5)=12

6x-30=12

6x=12+30

6x=42

6x/6=42/6

x=7

6y-5=12

6y=12+5

6y=17

6y/6=17/6

y=2 5/6
