Answer:

your answer is A chemical weathering

Step-by-step explanation:

as when volcanic gasses and atmospheric gasses mix it can become a sort of acidic rain in some cases I hope this answer helps I apologize for any wrong answers this is not my best subject but I wanted to attempt this as I k ow a small amount about it!

The process described in the question is known as acid rain, which is a type of chemical weathering. The correct answer would be option (A) chemical weathering.

When atmospheric and volcanic gases mix with water in the atmosphere, they can form acids such as sulfuric acid and nitric acid. These acids can then drop to the earth as acid rain. In rare situations, the mixing of volcanic and atmospheric gases can result in acidic rain.

Acid rain can cause chemical reactions with minerals in rocks and soil, dissolving them over time. This can lead to the breakdown of the rock or soil, which is an example of chemical weathering.

Thus, the process described in the question is known as acid rain, which is a type of chemical weathering.

Hence, the correct answer would be option (A) chemical weathering.

The ordered pairs of [tex]p(x) = x^{2}-2\cdot x -35[/tex] are [tex](r_{1}, p(r_{1})) = (-5, 0)[/tex] and [tex](r_{2},p(r_{2})) = (7,0)[/tex], respectively.

Step-by-step explanation:

Let be [tex]p(x)[/tex] a quadratic expression whose two real zeros are real, a value of [tex]x[/tex] is a zero of the expression when [tex]p(x) = 0[/tex]. The factored form of the expression is represented by [tex]p(x) = (x-r_{1})\cdot (x-r_{2})[/tex], where [tex]r_{1}[/tex] and [tex]r_{2}[/tex] are the zeroes of the polynomial.

If [tex]p(x) = x^{2}-2\cdot x -35[/tex], then the ordered pairs that represent the zeros are:

[tex](r_{1}, p(r_{1})) = (-5, 0)[/tex] and [tex](r_{2},p(r_{2})) = (7,0)[/tex]

Quadratic equation has a leading coefficient of the second degree. The ordered pairs of the quadratic equation are (-5,0) and (7,0).

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.

It is written in the form of ax²+bx+c.

As the factors of the quadratic equation are given, therefore, equating the factors with zero in order to get the value of x.

[tex](x+5)=0\\x = -5[/tex]

[tex](x-7)=0\\x = 7[/tex]

Now, if we see the quadratic equation or the function it is written as,

[tex]y = x^2-2x-35 \\\\ x^2-2x-35 = 0[/tex]

Therefore, the value of y is 0.

Thus, the ordered pairs of the quadratic equation are (-5,0) and (7,0).

Answer:  here is the answer

The equation of the line that has a slope of -1 and a y-intercept of -6 is:

y=-1x-6.

Step-by-step explanation:  here is the explanation

You want to find the equation for a line that has a slope of -1 and a y-intercept of -6.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

All you really have to do here is

replace m with -1, which is the slope you gave, and

replace b with -6, the y-intercept you gave,

in the equation y=mx+b.

The equation of the line that has a slope of -1 and a y-intercept of -6 is:

y=-1x-6.

Step-by-step explanation:

Good Luck!

Answer:

Answer in explanation.

Step-by-step explanation:

Lets take

[tex]y = \frac{3}{4} x - 5[/tex]

as L1.

Take L2 the line perpendicular to L1.

Standard form of equation of line:

y=mx+c, where m = slope and c = y-intercept.

Since L1 and L2 are perpendicular,

mL1 x mL2 = -1

Substitute mL1 into the equation,

3/4 x mL2 = -1

mL2 = -1 ÷ 3/4

mL2 = -4/3

L2 : y = mx+ c

Substitute y = 6, x = 8 and m = -4/3 into the equation,

[tex]6 = - \frac{4}{3} (8) + c \\ 6 = - \frac{32}{3} + c \\ c = 6 + \frac{32}{3} \\ = 16 \frac{2}{3} [/tex]

therefore L2:

[tex]y = - \frac{4}{3}x + 16 \frac{2}{3} [/tex]

Lets take L3 as the line parallel to L1.

Since L3 and L1 are parallel,

mL3 = mL1 = 3/4

equation of line: y = mx+c

substitute y = 6, x = 8 and m = 3/4 into equation.

[tex]6 = ( \frac{3}{4} )(8) + c \\ 6 = 6 + c \\ c = 6 - 6 \\ = 0[/tex]

therefore L3:

[tex]y = \frac{3}{4} x[/tex]

Answer:

x = 4, 10a

Step-by-step explanation:

3(x-2) + 2(2x+5) = 32

3x - 6 + 4x + 10 = 32

3x + 4x + 10 - 6 = 32

7x + 4 = 32

7x = 32 - 4

7x = 28

Divide both side by 7

x = 4

a + 2a + 7a

They are common because the have the same variables.

'a' is with a coefficient of 1

You add the coefficient and attach the variable to it

Therefore,

a + 2a + 7a = 10a

The coordinates of the image after a rotation of 180° counterclockwise about the origin is A' ( 7 , 3 )

The measure of the amount a figure is rotated about the center of rotation is called the angle of rotation. The angle of rotation is usually measured in degrees. We specify the degree measure and direction of a rotation.

90° clockwise rotation: (x,y) becomes (y,-x)

90° counterclockwise rotation: (x,y) becomes (-y,x)

180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

270° clockwise rotation: (x,y) becomes (-y,x)

270° counterclockwise rotation: (x,y) becomes (y,-x)

Given data ,

Let the coordinate of the point be A

Now , the value of A is A ( -7 , -3 )

And , 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y)

So , the coordinates of the image is A'

And , the value of A' = A' ( 7 , 3 )

Hence , the rotation is solved and the image is A' ( 7 , 3 )
