Answer:
Step-by-step explanation:
Given the vectors u = (1, −1, −2) and v = (1, 1, 2),
projection of u on v is expressed as [tex]proj_v u = \dfrac{u*v}{|v|^2}*v[/tex]
u.v = (1, −1, −2).(1, 1, 2)
u.v = 1(1)+(-1)(1)+(-2)(2)
u.v = 1-1-4
u.v = -4
|v| = √1²+1²+ 2²
|v| = √1+1+4
|v| = √6
|v|² = (√6)²
|v|² = 6
[tex]proj_v u = \dfrac{-4}{6}*(1,1,2)\\proj_v u = (\dfrac{-4}{6}, \dfrac{-4}{6}, \dfrac{-4}{3} )[/tex]
Similarly for projection of v on u;
[tex]proj_u v = \dfrac{u*v}{|u|^2}*u[/tex]
|u| = √1²+(-1)²+ (-2)²
|u| = √1+1+4
|u| = √6
|u|² = (√6)²
|u|² = 6
[tex]proj_u v = \dfrac{-4}{6}*(1,-1,-2)\\proj_u v = (\dfrac{-4}{6}, \dfrac{4}{6}, \dfrac{4}{3} )[/tex]
Move the horizontal and vertical sliders some more to stretch the image of the triangle. As you move the
sliders, observe what happens to the interior angles of each triangle. Based on your observations, can you say
that stretches preserve angle measurements?
Answer:

Scenario:You are a Geographic Information System (GIS) specialist who normally works at the Public Works Planning office.You are directed to report to the Incident Command Post (ICP) and have been assigned to the Planning Section Chief and will report to the Chief.You will be producing maps to display potential flooding impacts in the city and county.What NIMS Management Characteristics are you supporting? Select the two characteristics that apply.a. Integrated Communicationsb. Establishment and Transfer of Commandc. Chain of Command and Unity of Commandd. Accountabilitye. Dispatch/Deploymentf. Information and Intelligence Management
Answer: Chain of Command and Unity of Command ; Information and Intelligence Management
Step-by-step explanation:
Chain of Command typically loooks into an organization's hierarchical structure while unity of commands simply has to do with the reporting to ones designated supervisor.
Also, because maps are being produced, there'll be with the gathering, assessing, analyzing, sharing, and managing intelligence.
Therefore, the NIMS Management Characteristics that'll be supported are Chain of Command and Unity of Command ; Information and Intelligence Management.
The NIMS management characteristics that are mostly supported are:
A chain of Command is a unity of command.information and intelligence management.The chain of command and unity of command is an overall hierarchy of the orpganization, while the unity of command says that the entire chain is always reporting to the similarly designated supervisor.
The information and intelligent management help the owner to take according to decisions forward premises of the information system.
As per the GIS when the maps have the process for the information would be gathering the information, assessing it, analyzing it, sharing the information to the delegated conducting the field, and then managing the intelligence of the information.
Thus, the NIS characteristics are chain and unity of command, and information and intelligence management.

Answer:
4
Step-by-step explanation:
1) First, distribute the negative sign to the -7. Because of this, the -7 will become a positive 7.
Equation: -3+7
2) Next, whenever there are two different signs, we are supposed to subtract the bigger number (7) with the smaller number (3).
Equation: 7-3=4
3) Finally, assign the greatest number sign. in this case, 7 is the greater number, and the 7 is a positive number; therefore, it will be a positive 4.

The New Jersey Division of Fish and Wildlife keeps track of the beaver population in the Raritan River. They tagged 42 beavers and released them. A week later, they captured 54 beavers, including 14 tagged beavers. What is a good estimate of the beaver population in the Raritan River? There are approximately beavers in the Raritan River.
Answer:ratio is 14:54 = 42:B. Beavers = 162
Step-by-step explanation:
The ratio demonstrates how often one number is multiplied by another.
The approximate number of beavers exists 162.
What is meant by ratio?The ratio demonstrates how often one number is multiplied by another. When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage.
The relationship or comparison between two numbers in the same unit to determine how much larger one number is than the other is known as a ratio.
The 42 beavers were tagged and released by the New Jersey Division of Fish and Wildlife, which monitors the beaver population in the Raritan River. After a week, they had captured 54 beavers, 14 of which were marked. There are 54 Beavers in all, and 14 Beavers have tags.
Let the ratio be 14 : 54.
As 42 tagged beavers were released.
simplifying the above equation, we get
14 × 3 : 54 × 3
= 42 : 162
Therefore, the approximate number of beavers exists 162.

Today, 8 friends went out for lunch. Their total bill was $43.53, including tax and gratuity. One of them ordered only soda and needed to pay only $1.74. The
other 7 friends ordered the same daily special. How much did each of the other friends need to pay?
Answer:
5.97
Step-by-step explanation:
If one of them only ordered soda which costs $1.74 then you do 43.53 - 1.74 =41.79. Then do 41.79 divided by the other 7 people. 41.79 divided by 7 gets you the answer $5.97

What are the minimum and maximum values of x, for which x3 + x2 – 6x ≥ 0? minimum = –3, maximum = 0 minimum = 0, maximum = 2 minimum = –3, no maximum minimum = 2, no maximum Please answer quickly
Answer: Option C.
Step-by-step explanation:
The given inequality is
[tex]x^3+x^2-6x\geq 0[/tex]
Taking x common, we get
[tex]x(x^2+x-6)\geq 0[/tex]
Splitting the middle term, we get
[tex]x(x^2+3x-2x-6)\geq 0[/tex]
[tex]x(x(x+3)-2(x+3))\geq 0[/tex]
[tex]x(x+3)(x-2)\geq 0[/tex]
Related equation is
[tex]x(x+3)(x-2)=0[/tex]
[tex]x=-3,0,2[/tex]
These three points divide the number line in 4 parts.
Interval Sign of [tex]x(x+3)(x-2)\geq 0[/tex] Statement
(-∞,-3) [tex](-)(-)(-)=(-)[/tex] False
(-3,0) [tex](-)(+)(-)=(+)[/tex] True
(0,2) [tex](+)(+)(-)=(-)[/tex] False
(2,∞) [tex](+)(+)(+)=(+)[/tex] True
So, the solution set is (-3,0) ∪ (2,∞).
Thus, minimum value is –3 and no maximum value.
Therefore, the correct option is C.

I need to find the measurement of AEB please help me!
Triangle BEC is an isosceles triangle.
The angles opposite the congruent sides are equal
x = measure of missing angle
180 = 54 + 2x
Subtract 54 from both sides
126 = 2x
Divide both sides by 2
63 = x
angle EBC and angle C = 63 degrees
Angle EBC and angle EBA are supplementary.
This means they add up to 180 degrees
180 = 63 + EBA
Subtract 63 from both sides
117 = EBA
the measure of a triangle = 180
Therefore,
The measure of angle AEB = 180 - (40 + 117) = 23 degrees

The total weight of a rock depends on its size and is proportional to its density. In this context, density is the weight per cubic inch. Let w denote the weight of the rock in pounds, s the size of the rock in cubic inches, and d the density of the rock in pounds per cubic inch. If a 48-cubic-inch rock weighs w pounds, write an equation that shows the proportional relation.
Answer:
[tex]d = \frac{w}{48}[/tex]
If [tex]\frac{1}{48} \\[/tex] is constant, say k
Then,
[tex]d = kw[/tex]
∴ d ∝ w
Hence, weight is proportional to the density
Step-by-step explanation:
From the question,
Let w denote the weight of the rock in pounds
s denote the size of the rock in cubic inches and
d denote the density of the rock in pounds per cubic inch.
First, we will write the equation connecting w, s, and d.
We get
[tex]density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }[/tex]
That is,
[tex]d = \frac{w}{s}[/tex]
Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write
[tex]d = \frac{w}{48}[/tex]
If [tex]\frac{1}{48} \\[/tex] is constant, say k
Then,
[tex]d = kw[/tex]
∴ d ∝ w
Hence, density is proportional to the weight OR weight is proportional to the density

Answer:
7/10ths of the picture has been digested.
Step-by-step explanation:
Let's divide this into tenths.
One fifth out of ten is equal to two, since 10/5 = 2. A half of ten is five, because 10/2 = 5. Adding five and two together gives us 7/10ths, which can not be reduced to a smaller amount.
