Of all rectangles with area 324324, which one has the minimum perimeter? Let P and w be the perimeter and width, respectively

ra1l [238]

Answer:

For w = 18 units perimeter is minimum

P = 2(18 + w)

Step-by-step explanation:

Given;

Area of the rectangle = 324 units²

P is the perimeter

w is the width

Let L be the length of the rectangle

therefore,

P = 2(L + w) ............(1)

also,

Lw = 324

L = $\frac{324}{w}$ ..........(2)

substituting 2 in 1

P = $2(\frac{324}{w} + w)$

now,

for minimizing the perimeter

$\frac{dp}{dw}=\frac{d(2(\frac{324}{w} + w))}{dw}$ = 0

$2((-1)\frac{324}{w^2}+1)$ = 0

$(-1)\frac{324}{w^2}+1$ = 0

$(-1)\frac{324}{w^2}$ = -1

w² = 324

w = 18 units

For w = 18 units perimeter is minimum

therefore,

from 2

L = $\frac{324}{18}$

L = 18 units

objective function for P is:

P = 2(18 + w)

Anya says, 62,996 rounds to 63,000 select all the places to which she could have rounded the number

OLga [1]

She could round this number may it be in the tens and hundreds place. When rounding off a number, one should consider the place of the digit he or she would like to round it off to. One should consider what number is placed at the right of the rounding number. If the number is below 5, then that digit should remain and the rest of the digits to the right should be turned to 0s.

1. The area A = _r2 of a circular oil spill changes with the radius. At what rate does the area change with respect to the radiu

emmasim [6.3K]

1.) A = πr^2
Rate of change (dA/dr) = 2πr.
When r = 3, dA/dr = 2(3)π = 6π ft^2/ft

2.) V = πr^2h
Rate of change of volume given constant r is dV/dt = πr^2dh/dt = π(6)^2(3) = 108π cm^3/min
