Answer:

156 inches^2

Step-by-step explanation:

The area of a triangle is 1/2 base x height

All of the triangles have a base of 6 inches and a height of 10 inches.

so 1/2 6 x 10= 30

There are 4 triangles with an area of 30 square inches

and then the square in the middle has a length of 6 in and a width of 6 in so it has an area of 36 in^2

so in total you would have 30+30+30+30+36, or 156

The cost to produce a certain product depends on 3 main variables, denoted p, q, and r. If C(p, q, r) = C0e−2p + 7q − 9r represe

ad-work [718]

Answer:

$\sqrt{134}C_0e^{95}$

Step-by-step explanation:

We are given that the cost function is given by

$C(p,q,r)=C_0e^{-2p+7q-9r}$

$\nabla C(p,q,r)=< -2C_0e^{-2p+7q-9r},7C_0e^{-2p+7q-9r},-9C_0e^{-2p+7q-9r}>$

We have to find the rate of decrease of this function at the point $P_0(100,55,10)$

$\nabla C(100,55,10)=$

$\nabla C(100, 55,10)=$

$\mid \nabla C(100, 55, 10)\mid=\sqrt{(-2C_0e^{95})^2+(7C_0e^{95})^2+(-9C_0e^{95})^2}$

Greatest rate of decrease of this point at the point $P_0(100,55,10)$ is given by

$\mid \nabla C(100, 55, 10)\mid=\sqrt{134}C_0e^{95}$
