when do convection currents form?

Answers

Answer 1

Answer:

Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

What is a Parallelogram?

It is a polygon with four sides. The total interior angle is 360 degrees. A Parallelogram's opposite sides are parallel and equal. Its diagonals intersect in the center.

If BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6. The equation is given as,

BD = 2BE

5x - 3 = 2(2x + 2)

5x - 3 = 4x + 4

x = 9

Then the value of the line segment AE is given as,

AE = 4(9) - 6

AE = 36 - 6

AE = 30 units

Then the value of the line segment AC is given as,

AC = 2AE

AC = 2(30)

AC = 60 units

The value of the variable 'x' is 9 units. Then the length of the line segment will be 60 units.

Write a quadratic equation in standard form with the given roots. 3/2, 1/4

Answers

Answer:

The quadratic equation in standard form is  [tex]y= x^{2}-\frac{7}{4}\cdot x +\frac{3}{8}[/tex].

Explanation:

From Algebra, we remember that the order of the polynomial indicates the number of roots contained within. The factorized form of a second order polynomial (quadratic equation) is now introduced:

[tex]y = (x-r_{1})\cdot (x-r_{2})[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]r_{1}[/tex], [tex]r_{2}[/tex] - Roots of the polynomial.

And the standard form of the quadratic equation:

[tex]y = a\cdot x^{2}+b\cdot x +c[/tex] (2)

Where [tex]a[/tex], [tex]b[/tex], [tex]c[/tex] are the coefficients of the polynomial.

Lastly, we proceed to perform algebraic operations until standard form is found:

1) [tex]r_{1} = \frac{3}{2}[/tex], [tex]r_{2} = \frac{1}{4}[/tex] Given

2) [tex]y = \left(x-\frac{3}{2}\right)\cdot \left(x-\frac{1}{4} \right)[/tex] By 1)/Definition of factorized form

3) [tex]y = \left[x+\left(-\frac{3}{2} \right)\right]\cdot \left[x+\left(-\frac{1}{4} \right)\right][/tex] Definition of subtraction

4) [tex]y = \left[x+\left(-\frac{3}{2} \right)\right]\cdot x +\left[x+\left(-\frac{3}{2} \right)\right]\cdot \left(-\frac{1}{4} \right)[/tex] Distributive property

5) [tex]y = x\cdot x +\left(-\frac{3}{2} \right)\cdot x +\left(-\frac{1}{4}\right)\cdot x +\left(-\frac{3}{2}\right)\cdot \left(-\frac{1}{4} \right)[/tex] Distributive and commutative properties

6) [tex]y = x^{2} + \left[-\left(\frac{3}{2}+\frac{1}{4}\right)\right]\cdot x +\left(-\frac{3}{2} \right)\cdot \left(-\frac{1}{4} \right)[/tex] Distributive and associative properties/[tex](-1)\cdot a = -a[/tex]

7) [tex]y = x^{2}+\left(-\frac{7}{4} \right)\cdot x + \frac{3}{8}[/tex]  [tex]\frac{a}{b}\times \frac{c}{d} = \frac{a\cdot c}{b\cdot d}[/tex]/[tex](-a)\cdot (-b) = a\cdot b[/tex]

8) [tex]y= x^{2}-\frac{7}{4}\cdot x +\frac{3}{8}[/tex] Definition of substraction/Result

What is zonation?

Changes in community along an environmental gradient caused by factors such as altitude, latitude, tidal level, or distance from shore are referred to as zonation (coverage by water). Abiotic conditions differ between the several vertical layers.

This vertical zonation in Rocky Mountain flora is commonly attributed to climatic conditions such as temperature and moisture content. As a result of the cooler temperatures, humans are affected. Wind exposure, wave motion, salinity, temperature, and light intensity are among the different factors.
