Answer:
[tex]1.\ A(3 , -4)\ B(-4 , 3)\ C(0 , 0)[/tex] -- Not right triangle
[tex]2.\ O(2 , 5)\ P(-1 , 3)\ Q(7 , 4)[/tex] -- Not right triangle
[tex]3.\ T(1 , 1)\ U(3 , 3)\ V(5 , 1)[/tex] -- Right triangle
Explanation:
Required
Determine whether the given points make a right triangle
[tex]1.\ A(3 , -4)\ B(-4 , 3)\ C(0 , 0)[/tex]
First, calculate the distance between each point using:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
So, we have:
[tex]AB = \sqrt{(3 - -4)^2 + (-4 - 3)^2}= \sqrt{98} = 7\sqrt 2[/tex]
[tex]BC = \sqrt{(-4 - 0)^2 + (3 - 0)^2}= \sqrt{25} = 5[/tex]
[tex]AC = \sqrt{(3 - 0)^2 + (-4 - 0)^2}= \sqrt{25} = 5[/tex]
From the above computations, the longest side is AB.
So;
[tex]AB^2 = BC^2 + AC^2[/tex] --- Test of Pythagoras
[tex](7\sqrt 2)^2 = 5^2 + 5^2[/tex]
[tex]98 = 25 + 25[/tex]
[tex]98 \ne 50[/tex]
The above points do not make a right triangle
[tex]2.\ O(2 , 5)\ P(-1 , 3)\ Q(7 , 4)[/tex]
Calculate distance
[tex]OP = \sqrt{(2 - -1)^2 + (5 - 3)^2}= \sqrt{13}[/tex]
[tex]PQ = \sqrt{(-1 -7)^2 + (3 - 4)^2}= \sqrt{65}[/tex]
[tex]OQ = \sqrt{(2 -7)^2 + (5 - 4)^2}= \sqrt{26}[/tex]
From the above computations, the longest side is PQ
So;
[tex]PQ^2 = OP^2 + OQ^2[/tex] --- Test of Pythagoras
[tex]\sqrt{65}^2 = \sqrt{13}^2 + \sqrt{26}^2[/tex]
[tex]65 = 13 + 26[/tex]
[tex]65 \ne 39[/tex]
The above points do not make a right triangle
[tex]3.\ T(1 , 1)\ U(3 , 3)\ V(5 , 1)[/tex]
Calculate distance
[tex]TU = \sqrt{(1 -3)^2 + (1 - 3)^2}= \sqrt{8} = 2\sqrt2[/tex]
[tex]UV = \sqrt{(3 -5)^2 + (1 - 3)^2}= \sqrt{8} = 2\sqrt2[/tex]
[tex]TV = \sqrt{(1 -5)^2 + (1 - 1)^2}= \sqrt{16} = 4[/tex]
From the above computations, the longest side is TV
So;
[tex]TV^2 = TU^2 + UV^2[/tex] --- Test of Pythagoras
[tex]4^2 = (2\sqrt 2)^2 +(2\sqrt 2)^2[/tex]
[tex]16 = 8 + 8[/tex]
[tex]16 = 16[/tex]
The above points not make a right triangle

Answer:
It is runoff.
Explanation:
ur welcome
Answer:
Runoff
Explanation:
The stage of water cycle where water moves downward from the force of gravity is runoff.
It comes after the precipitation stage when the water has fallen in a form of rain and seep through the soil, due to the force of gravity this water moves down the hills and mountains through a process called runoff.
Under the force of gravity, water follows along the steep hills and then join into stream and rivers. Later on these streams and rivers will move down to join lakes and oceans.
Do you see nationalism as mainly a constructive or destructive force? why? need help ASAP??!?!?!
Answer:
destructive
Explanation:
Nationalism promotes the ideas of the nation in question and is has been called loyalism. However, its is different from patriotism as patriotism is a strong connection and support for ones country. Nationalism is supporting your country to the point you care about your country more than the people around you. In nationalism, the country is not questioned it is just supported by others.
the interior composition and structure of earth have been deducted in part from: a) analyses of the behaviour of seismic waves b) chemical studies of meteorites c) the density of iron, granite and basalt d) all of the above.
Answer: A. Analyses of the behavior of seismic waves.
Explanation: "The layering of Earth has been inferred indirectly using the time of travel of refracted and reflected seismic waves created by earthquakes" (Structure of the Earth). Combining the layered structure and reflection magnitudes with the magnitude of gravity (and therefore the average density of the Earth), we can get a pretty good idea of the density of each layer. By integrating density, we can calculate the pressures at depth."

Typically, deforestation is clearing a lot of trees without the intention of establishing future growth. Harvesting, forest fires, and insect infestations do not count as deforestation because the affected areas will eventually grow back.

how the Maori people used natural resources to meet their needs and an example of products made from these natural elements
Answer:
Maori sustainable practices were applied to many different kinds of natural resources. The group had a vast knowledge about the land and the crops that grew there. ... Their knowledge extended to how plants could be used as medicine and how they could heal certain ailments.Four distinct types of messages were also identified: general awareness of fire risk; information about fire use restrictions; ways to prevent fires starting; and how best to be prepared should a wildfire (at household, property and community levels) start.
Explanation:
Write one paragraph explaining how natural resources, population, and trade are related.

why do mountainous region have lower temperature than the lowlands?
Answer:
The air in our atmosphere is a poor conductor because it is not dense with particles, so the thin air in the mountains keeps them colder than the thicker air in the lowlands
Explanation:
how can poor infrastructure be a cause of drought pls explain in not a sophisticated way :)
Answer: Infrastructure can be responsible for drought.
Explanation:
Drought is a natural disaster in which the area receives a very low amount of annual rainfall. This causes the scarcity of water on the land. The natural and artificial reservoirs of water get dried up in drought as water does not accumulate and replenish in this reservoir because of lack of adequate rainfall. Infrastructure can cause drought if there is no sufficient artificial reservoir which can help in irrigation of field, use for household works, and for other purposes which can help in scarcity of water. Infrastructure which reduces the forest cover also affects the water cycle causing drought in neighboring regions.

What problems can temperature inversions create?
Group of answer choices
can cause hail, rain and high winds
can cause cyclones to form
can create dust storms making air hard to breath
can trap polluted air causing health problems
Answer: Can trap polluted air causing health problems
Explanation:
Temperature inversion usually occurs when warm air, which is lighter than cold air, moves above cold air and traps it by acting as a sort of lid over it.
As a result of this, vertical mixing of air is suppressed such that pollution cannot diffuse upward but would remain closer to the surface where it is then likely to cause health problems when people are exposed to it for a longer time.
Do you think people could learn history and math better from video games than the types of school activities most people do now?
Answer:
It really depends on the person
Explanation:
If you made a game that was about ww2 and you played a leader and made choices that might work but then you not learning the real history because your making your own choices. For math I would think that if you played a game that required a lot of math like an Engineering game that could work. I know you didn't ask this in you question but for learning a language I have a lot of friends that change the language of a game to the language there learning so if there playing a game like Minecraft the could learn when there playing.
