the legnth of a rectangle is three times its width. if the length of the perimeter is 64 in, find the length and width

egoroff_w [7]

Answer:

Length and width of rectangle is 24 and 8 inches

Step-by-step explanation:

Given:

Length of rectangle is three times the width
Perimeter of rectangle is 64 Inches

To Find:

Length and Width

Solution:

Let's assume Width of rectangle x inches and length be 3x inches. To calculate the dimensions of The rectangle we will use the formula of Perimeter of rectangle:

Perimeter of rectangle = 2(L + B)

→ 64 = 2(3x + x)

→ 64 = 2(4x)

→ 64/2 = 4x

→ 32 = 4x

→ 32/4 = x

→ 8 = x

Hence,

Length of the rectangle = 3x = 3(8) = 24 inches

Width of the rectangle = x = 8 inches

Let f be a function of two variables that has continuous partial derivatives and consider the points a(7, 3), b(12, 3), c(7, 7),

luda_lava [24]

The directional derivative of a function $f(x,y)$ in the direction of $\mathbf v$ is given by

$\nabla f(x,y)\cdot\mathbf v$

We have $\vec{ab}=\mathbf b-\mathbf a=(12-7,3-3)=(5,0)$ , so that $\|\vec{ab}\|=5$ , at which point we're given

$\nabla f(7,3)\cdot\dfrac{(5,0)}5=5\implies1\cdot\dfrac{\partial f}{\partial x}(7,3)+0\cdot\dfrac{\partial f}{\partial y}(7,3)=5$

$\implies\dfrac{\partial f}{\partial x}(7,3)=5$

We're also given that, in the direction of $\vec{ac}=\mathbf c-\mathbf a=(7-7,7-3)=(0,4)$ with $\|\vec{ac}\|=4$ , we have

$\nabla f(7,3)\cdot\dfrac{(0,4)}4=4\implies0\cdot\dfrac{\partial f}{\partial x}(7,3)+1\cdot\dfrac{\partial f}{\partial y}(7,3)=4$

$\implies\dfrac{\partial f}{\partial y}(7,3)=4$

So in the direction of $\vec{ad}=\mathbf d-\mathbf a=(15-7,9-3)=(8,6)$ , with $\|\vec{ad}\|=10$ , we have

$\nabla f(7,3)\cdot\dfrac{(8,6)}{10}=\dfrac1{10}(4,4)\cdot(8,6)=9.60$
