How do you implicitly differentiate: sqrt(xy)=x^2y+1

Mathematics

Furkat [3]2 years ago

Implicit expression refers to equation that are not strictly expressed in terms of y and x separately. In this case, the derivative of expression 
<span>sqrt(xy)=x^2y+1 is

sqrt x * 0.5 y ^-0.5 dy + </span>sqrt y<span> * 0.5 x ^-0.5 dx= x^2 dy + 2xy dx 
dy (x^2 - 0.5 (</span>x/y) ^0.5) = dx (2xy  - 0.5 (y<span>/x)^0.5) 
dy/dx = </span>(2xy  - 0.5 (y/x)^0.5) / (x^2 - 0.5 (<span>x/y) ^0.5)</span>

Which expression has a value that is less than the base of that experience?
Rom4ik [11]

Answer:

(B) (\frac{5}{6})^{2}

Step-by-step explanation:

(A) The given expression is: 2^{3}

=8

The value of this expression is 8 which is greater than the base of the expression that is 2.

(B) The given expression is: (\frac{5}{6})^{2}

=\frac{25}{36}

=0.09

The value of this expression is 0.09 which is smaller than the base of the given expression that is 0.83.

(C) The given expression is: 3^{2}

=9

The value of this expression is 9 which is greater than the base of the given expression that is 3.

(D) The given expression is: 4^{4}

=256

The value of this expression is 256 which is greater than the base of the given expression that is 4.

At Super Grocery, potatoes cost $2.85 for 5 pounds. At Value Market, potatoes cost $4.20 for 7 pounds. What is the unit price of
Mashcka [7]

Answer:

$1.66 per pound of potatoes.

Step-by-step explanation:

I think you can just ignore the part at the beginning, this is probably a multi-part question.

unit price is just amount/cost so all you need to do is substitute that.

7/4.20 = 1.66$ per Pound

Good luck with your schoolwork/homework!

There are 25 green marbles in a jar. The total number of red marbles and green marbles equals the number of blue marbles. For ev
Anuta_ua [19.1K]

Answer:

Green = 25 Yellow = 30 Red = 15 Blue = 40

If there are 25 there should be five groups so there are 5 groups and 6 yellow for each so 6 x 5 = 30 so 30 yellow

if there are 30 yellow and 1 read marble for each 2 there are 15 bcuz 30 divided by 2 = 15

now if you add the red and green you get 40.

Hopefully thats right!

Plot and connect the points A(4, 6), B(4, 0), C(1, -3), and D(1, 3), and find the area of the parallelogram formed.
fgiga [73]
I got C. 20 square units.

I could be wrong, but probably not. It was hard to figure out what the plot numbers were and the answer choices because the picture was super blurry. That's why I said I might be wrong.

Hope this helps!! :-)
