Answer:

Check the figure attached.

Step-by-step explanation:

We have

Expression in Rectangle 1= 4x+3y

Expression in Rectangle 2 = 2x-y

Their sum will be in circle 1

adding:

$4x+3y+2x-y \\=4x+2x+3y-y\\=6x+2y$

Now using the expression in Rectangle 3 and circle 3, we can find expression Of rectangle 4. Let it be Exp

$x+4y+Exp=4x+5y\\Exp=4x+5y-(x+4y)\\Exp=4x+5y-x-4y\\Exp=4x-x+5y-4y\\Exp=3x+y\\$

Now using Expression in rectangle 2 and 4 to find result for circle 3

$2x-y+3x+y\\=2x+3x-y+y\\=5x$

Now adding terms in the figure

The width of a rectangle is increasing at a rate of 2 cm/sec, while the length increases at 3 cm/sec. At what rate is the area i

lorasvet [3.4K]

Answer:

The area of the rectangle is increasing at a rate of $22\ cm^2/s$ .

Step-by-step explanation:

Given : The width of a rectangle is increasing at a rate of 2 cm/ sec. While the length increases at 3 cm/sec.

To find : At what rate is the area increasing when w = 4 cm and I = 5 cm?

Solution :

The area of the rectangle with length 'l' and width 'w' is given by $A=l w$

Derivative w.r.t 't',

$\frac{dA}{dt}=w\frac{dl}{dt}+l\frac{dw}{dt}$

Now, we have given

$\frac{dl}{dt}=3\ cm/s$

$l=5\ cm$

$\frac{dw}{dt}=2\ cm/s$

$w=4\ cm$

Substitute all the values,

$\frac{dA}{dt}=(4)(3)+(5)(2)$

$\frac{dA}{dt}=12+10$

$\frac{dA}{dt}=22\ cm^2/s$

Therefore, the area of the rectangle is increasing at a rate of $22\ cm^2/s$ .

Answer:

Mean of the binomial distribution μ = 2.38

Standard deviation of the binomial distribution σ = 1.2533

Step-by-step explanation:

Explanation:-

Given Population proportion

p = 34 % = 0.34

q = 1- p

= 1 -0.34

= 0.66

q = 0.66

Mean of the binomial distribution

μ = n p = 2.38

Standard deviation of the binomial distribution

σ = √n p q = 1.2533
