You need to multiply 25 by 18 to find the total.

25 x 18 = 450.

There are 450 chocolate bars in the large box

Evaluate the surface integral S F · dS for the given vector field F and the oriented surface S. In other words, find the flux of

Law Incorporation [45]

Answer:

Step-by-step explanation:

To solve this problem, we will use the following two theorems/definitions:

- Given a vector field F of the form (P(x,y,z),Q(x,y,z),W(x,y,z)) then the divergence of F denoted by $\nabla \cdot F = \frac{\partial P}{\partial x}+\frac{\partial Q}{\partial y}}+\frac{\partial W}{\partial z}$

- (Gauss' theorem)Given a closed surface S, the following applies

$\int_{S} F\cdot \vec{n} dS = \int_{V} \nabla \cdot F dV$

where n is the normal vector pointing outward of the surface and V is the volume bounded by the surface S.

Let us, in our case, calculate the divergence of the given field. We have that

$\nabla \cdot F = \frac{\partial}{\partial x}(x)+\frac{\partial}{\partial y}(2y)+ \frac{\partial}{\partial z}(5z) = 1+2+5 = 8$

Hence, by the Gauss theorem we have that

$\int_{S} F\cdot \vec{n} dS = \int_{V} 8 dV = 8\cdot\text{Volume of V}$

So, we must calculate the volume V bounded by the cube S.

We know that the vertices are located on the given points. We must determine the lenght of the side of the cube. To do so, we will take two vertices that are on the some side and whose coordinates differ in only one coordinate. Then, we will calculate the distance between the vertices and that is the lenght of the side.

Take the vertices (1,1,1) and (1,1-1). The distance between them is given by

$\sqrt[]{(1-1)^2+(1-1)^2+(1-(-1)^2} = \sqrt[]{4} = 2$ .

Hence, the volume of V is $2\cdot 2 \cdot 2 = 8$ . Then, the final answer is

$\int_{S} F\cdot \vec{n} dS =8\cdot 8 = 64$

Helen wants to buy a dictionary that costs $7, a dinosaur book that costs $16, and a children's cookbook that costs $17. She has

Hitman42 [59]

Answer:

Helen requires 15$ more to buy the three books.

Step-by-step explanation:

We are given the following in the question:

Cost of dictionary = $7

Cost of dinosaur book = $16

Cost of cook book = $17

Helen's allowance = $25

Total cost of three books =

$=7 +16+17\\=\$ 40$

Extra money required to buy three books =

$=40-25\\=\$15$

Thus, Helen requires 15$ more to buy the three books.

taurus [48]

Answer:

B) rose bush: $8, pot of ivy: $11

Step-by-step explanation:

12(8) + 13(11) = 239

remove parentheses: (a) = a

= 12 * 8 + 13 * 11

multiply the numbers: 12 * 8 = 96

= 96 + 13 * 11

multiply the numbers: 13 * 11 = 143

= 96 + 143

add the numbers: 96 + 143 = 239

= 239

Answer (numbers needed in boxes, going from top to bottom):

-1

-3

Step-by-step explanation:

f(x) is another way of saying y. So, the table is asking, "when substituting these x values for the x's in the function, what does y equal?" So, to answer the question, substitute each x value into the equation and solve.

1) Start with the x value of 1. Substitute 1 for x in y = 2x - 1 and solve:

$y = 2(1)-1\\y = 2 - 1\\y = 1\\$
