Answers

Answer:

m<B = 83°

Explanation:

The figure given is a parallelogram having opposite sides that area parallel to each other. Therefore, opposite angels are congruent while the adjacent angles are supplementary.

<A and <B are adjacent angles. Therefore,

m<A + m<B = 180°

97° + m<B = 180° (substitution)

m<B = 180° - 97

m<B = 83°

According to the hydrologic cycle, once precipitation has fallen on land, what paths might the water directly take? Select all that apply. View Available Hint(s) Select all that apply. evaporation/transpiration evaporation from the sea infiltration into the ground runoff into a river runoff into the sea

Answers

Answer:

evaporation/transpiration evaporation from the sea infiltration into the ground runoff into a river runoff into the sea

Explanation:

In hydrologic cycle, it shows the different pathways through which the water circulates in the environment leading to balanced biotic system. Just like air cycle, hydrologic cycle helps in keeping the living things like plants, humans in existence as well as aiding the non-living things like soil deposit, decayed plants materials, humus etc in equitable distribution.

The above showed process is the likely path through which water that was formed on the land due to rainfall (precipitation) circulates. Some are evaporated from sea infiltration into ground while some happen to flow from land into the river and sea.

Find the seventh term of the geometric sequence if a1 = 7 and r = 3

Answers

Answer:

The seventh term is 5,103.

Explanation:

Hey there!

We're given the initial term and the common ratio of an undetermined geometric sequence.

The formula to determine a geometric sequence is [tex]x_n = ar^{(n-1)}[/tex].

We know that a₁ is 7 and that r is 3. However, we don't know what n is. Our variable n is a stand in for the position in the sequence. Since we want 7 terms, we are going to have terms 1, 2, 3, 4, 5, 6, and 7. The variable n will equal each one of these.

Finally, our term xₙ is equivalent to the term we are trying to find, so it is a standalone variable.

Let's find all seven terms using the above formula.

We already have our first term: 7. Therefore, we set n equal to 2 and solve for xₙ.

Term 2

[tex]x_n = 7(3)^{(2-1)}\\x_n = 7(3)^1\\x_n = 7(3)\\x_n = 21[/tex]

Term 3

[tex]x_n = 7(3)^{(3-1)}\\x_n = 7(3)^2\\x_n = 7(9)\\x_n = 63[/tex]

Term 4

[tex]x_n = 7(3)^{(4-1)}\\x_n = 7(3)^3\\x_n = 7(27)\\x_n = 189[/tex]

Term 5

[tex]x_n = 7(3)^{(5-1)}\\x_n = 7(3)^4\\x_n = 7(81)\\x_n = 567[/tex]

Term 6

[tex]x_n = 7(3)^{(6-1)}\\x_n = 7(3)^5\\x_n = 7(243)\\x_n = 1701[/tex]

Term 7

[tex]x_n = 7(3)^{(7-1)}\\x_n = 7(3)^6\\x_n = 7(729)\\x_n = 5103[/tex]

We have found the seventh term to be 5,103.

The sequence is written as 7, 21, 63, 189, 567, 1,701, 5,103... (it will be ongoing if you wanted to calculate the next term).

To reduce this effect, emergency water supplies are crucial and needed to be stockpiled to establish shelters where people can take shelter during the storms.

How are tropical cyclones formed?

They are formed from the meeting of hot and humid air from tropical regions that rises to the upper layers of the atmosphere, while the denser and colder air sinks to the surface.

To reduce this effect, emergency water supplies are crucial and needed to be stockpiled to establish shelters where people can take shelter during the storms.

Government can also mandate storm insurance coverage.

Why do tropical cyclones develop in late summer?​

Answers

The tropical cyclones have a thermal origin, and they develop over tropical seas during late summers (August to mid-November). At these locations, the strong local convectional currents acquire a whirling motion because of the Coriolis force.

Tropical Cyclones are defined as a intense wind system divided into low-pressures, that are formed over tropical oceans.

Why do tropical cyclones develop in late summer?​

Tropical cyclones develop in the late summer because of the Atlantic Basin. There are two main things are needed for their formation that include warm ocean waters (80 degrees or higher) and weak vertical wind shear.

During the late summer months, the sea surface temperatures reach their highest levels and provide tropical cyclones with the energy they need to develop into major storms.
