By the chain rule,
It looks like we're given
where <em>a</em> and <em>b</em> are presumably constant.
Recall that
so that
Then we have
where the last reduction follows from dividing through everything by and simplifying.
I'm not sure at which point you're supposed to evaluate the derivative (22/7*4, as in 88/7? or something else?), so I'll leave that to you.
Please use the solution below:
Let P = perimeter, A = area
As provided above, a = xy and
We know that the formula to solve for the perimeter of a rectangle is P = 2x + 2y. Using the given 112m, we can solve the perimeter using the formula:
112 = 2x + 2y
56 = x + y
x = 56-y or y = 56-x
Let's solve the perimeter in terms of y using the formula below:
A = (56-y)(y)
Find the derivative of A = 56-y^2 to get the value of y.
dA/dy = 56-2y = 0
y = 56/2
y = 28
To find X, substitute the value of y in the equation x = 56 - y.
x = 56 - 28
Therefore, x = 28.
We can conclude that the figure is not a rectangle but a square.
You just have to take your multiplication table and then you can find what multiplication make 24
6x4=24
2x12=24
3x8=24
So 2 3 4 6 8 12 are all the multiples of 24
Answer:
$50.83
Step-by-step explanation:
44.20 x .15 = 6.63
44.20 + 6.63= 50.83
8/9 * 1/4 = 8/36 division of fractions is equal to the multiplication of the reciprocal
