Sancho paints the new sign for his bike shop. One quart of paint covers 200 square

patriot [66]

Slit the shape into a rectangle and two triangles:

Rectangle = 9 x 8 = 72 sq. Ft.

Triangle = 1/2 x 8 x 2.5 = 10 sq. Ft x 2 = 20 sq. Ft.

Total area = 72 + 20 = 92 sq. Ft.

3 coats x 92 = 276 sq ft worth of paint.

1 quart covers 200 so he would need to buy 2 quarts:

2 x $8.97 = $17.94 total

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

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