vitfil [10]

Complete question

A 29-meter ladder is sliding down a vertical wall so the distance between the top of the ladder and the ground is decreasing at 7 meters per minute. At a certain instant, the bottom of the ladder is 21 meters from the wall.

What is the rate of change of the distance between the bottom of the ladder and the wall at that instant(in meters per minute)

Answer:

$\frac{dx}{dt}=11.94m/min$

Step-by-step explanation:

From the question we are told that

Slant height $z=29m$

Change in Vertical height $\triangle y=7m/s$

Horizontal length $x=21$

Generally in finding the distance form the top to the bottom of the wall it is mathematically given by

$x^2+y^2=z^2$

$21^2+y^2=29^2$

$y^2=29^2+21^2$

$y=35.81$

Generally solving for the differential equation is mathematically represented as

$x^2+y^2=29^2$

$2x*\frac{dx}{dt} +2y*\frac{dy}{dt} =0$

$x*\frac{dx}{dt} +y*\frac{dy}{dt} =0$

$(21)*\frac{dx}{dt} +(35.81)*(-7) =0$

$(21)*\frac{dx}{dt} -250.64 =0$

$\frac{dx}{dt}=\frac{250.64}{21}$

$\frac{dx}{dt}=11.94m/min$

The length of Hillcrest Garden is 6 feet more than its width. A 3-foot wide walkway surrounds the outside of the garden. The tot

Ne4ueva [31]

Answer: The dimensions of the garden would be 18 feet and 24 feet.

Step-by-step explanation:

Let the width of garden be 'x'.

Let the length of garden be $'x+6'$

Since there is 3 foot wide walkway surrounds the outside the garden.

Area of walkway = 288 square feet

So, According to question, it becomes,

$2z(x+y+2z)\\\\288=2\times 3(x+x+6+2\times 3)\\\\288=6(2x+6+6)\\\\288=6(2x+12)\\\\\dfrac{288}{6}=2x+12\\\\48=2x+12\\\\48-12=2x\\\\36=2x\\\\x=\dfrac{36}{2}\\\\x=18$

Width = 18+6 =24 feet

Hence, the dimensions of the garden would be 18 feet and 24 feet.
