D. Chemical weathering
I think it is chemical weathering because it is a live thing.

The answer to this is C. because when the roots grow it can create cracks in sidewalks or rocks (mechanical) and the chemical part comes from the roots too, it releases acid which breaks down rocks

What is the growth percentage of h(x) = .5(2)" ?A200%B2%100%D10%

zaharov [31]

$h(x)=0.5(2)^x^{}$

We can compute the growth percentage, computing first, two consecutive values, as follows:

$\begin{gathered} h(1)=0.5(2)^1=0.5(2)=1 \\ h(2)=0.5(2)^2=0.5(4)=2 \end{gathered}$

Then, the growth percentage is:

$\frac{h(2)-h(1)}{h(1)}\cdot100=\frac{2-1}{1}\cdot100=100\text{ \%}$

A random sample of 384 people in a mid-sized city (city one) revealed 112 individuals who worked at more than one job. A second

Svetlanka [38]

Answer:

99% confidence interval is:

(0.00278 < P1 - P2< 0.15921)

Step-by-step explanation:

For calculating a confidence intervale for the difference between the proportions of workers in the two cities, we calculate the following:

$[(p_{1} - p_{2}) \pm z_{\alpha/2} \sqrt{\frac{p_{1}(1-p_{1})}{n_{1}} + \frac{p_{2}(1-p_{2})}{n_{2}} }$

Where $p_{1}$ : proportion sample of individuals who worked

at more than one job in the city one

$n_{1}$ : Number of respondents in the city one

$p_{1}$ : proportion sample of individuals who worked

at more than one job in the city two

$n_{1}$ : Number of respondents in the city two

Then

α = 0.01 and α/2 = 0.005

and $z_{\alpha/2} = 2.575$

$p_{1} = \frac{112}{384} = 0.2916$

$p_{2} = \frac{91}{432} = 0.2106$

$n_{1}= 384$ and $n_{2}= 432$

The confidence interval is:

$[(0.2916 - 0.2106) \pm 2.575 \sqrt{\frac{0.2916(1-0.2916)}{384} + \frac{0.2106(1-0.2106)}{432} }$

(0.00278 < P1 - P2< 0.15921)

Simplify (x − 4)(2x2 + 3x − 5).

xeze [42]

The simplified form of given expression is $2x^3-5x^2-17x+20$

<em><u>Solution:</u></em>

Given that we have to simplify the expression

<em><u>Given expression is:</u></em>

$(x-4)(2x^2+3x-5)$

We can simplify the expression by multiplying each term in first bracket with each term term in second bracket

$\rightarrow (x-4)(2x^2+3x-5)$

$\rightarrow (x)(2x^2)+(x)(3x)+(x)(-5)-4(2x^2)-4(3x)-4(-5)$

Simplify the above expression by multiplying the numbers in each term and adding the coefficients of like variables in each term

$\rightarrow 2x^3+3x^2-5x-8x^2-12x+20$

Combine the like terms

$\rightarrow 2x^3+3x^2-8x^2-5x-12x+20$

$\rightarrow 2x^3-5x^2-17x+20$

Thus the expression is simplified

Consider this cone. a cone. point a is the vertex, b is the height, c is the radius, and d is the diameter. identify the parts o

Nikolay [14]

The that indicates the height is AB
The letter that indicates the radius is CB
The letter indicates the diameter is CD
The letter indicates the vertex is A

A cone can be regarded as a three-dimensional shape which has a vertex at the top of it.

Considering a cone as described in the question, we could see that the distance from point A to B will gives us the height which is the vertical length.

Therefore, Vertex is at the top of the cone which is point A.
