Answer:

<em>Surface Area: 10.24 square feet</em>

Step-by-step explanation:

In order to find the surface area, part the figure into 5 shapes;   1 being a square, the other 4 being equivalent triangles

Now find the area of the square, provided the dimensions 0.8 by 0.8:

A = 0.8 * 0.8 = 0.64 square feet

The area of the triangles are equivalent knowing that the share similar dimensions, 0.8 feet for the base and 6 feet for the height, so let us find the area of one at first:

A = 1/2 * 0.8 * 6 = 3 * 0.8 = 2.4 square feet

This means that the area of all 4 triangles are:

A = 2.4 * 4 = 9.6 square feet

The total surface area of this pyramid would then be the sum of the area of all 5 shapes, triangles and square:

Surface Area = 9.6 + 0.64 = 10.24 square feet

Learning goal: to understand the rules for computing dot products. let vectors a=(2,1,−4), b=(−3,0,1), and c=(−1,−1,2). part a -
miv72 [106K]
For this case we have the following vectors:
 a = (2,1, -4)&#10;&#10;b = (- 3,0,1)&#10;&#10;c = (- 1, -1,2)
 The dot product of two vectors is a scalar.
 The point product consists of multiplying component by component and then adding the result of the multiplication of each component.
 For the product point of the vectors a and b we have:
 a.b = (2,1, -4). (- 3,0,1)&#10;&#10;a.b = (2) (- 3) + (1) (0) + (-4) (1)&#10;&#10;a.b = - 6 + 0 - 4&#10;&#10;a.b = - 10
 Answer:
 
The product point of the vectors a and b is: 
 
a.b = - 10

frosja888 [35]

Answer:

$66

Step-by-step explanation:

The meal cost $50 without taxes.

The cost of tax:

$50*%14= $7

so she will pay a $7 tax

Also, she wants to tip %18 of the original $50 so:

$50*%18= $9

so she will tip $9

$50 + $7 + $9 = $66
