Determine whether LINE AB and LINE CD are parallel, perpendicular, or neither. A(−1, −4) , B(2, 11) , C(1, 1) , D(4, 10) ( write
Luba_88 [7]

Step-by-step explanation:

Hey there!

The points of line AB are; (-1,-4) and (2,11).

Note:

  • Use double point formula and simplify it to get two eqaution.
  • Use condition of parallel lines, perpendicular lines to know whether the lines are parallel or perpendicular or nothing.

~ Use double point formula.

(y - y1) =  \frac{y2 - y1}{x2 - x1} (x - x1)

~ Keep all values.

(y  + 4) =  \frac{11 + 4}{2 + 1} (x + 1)

~ Simplify it.

y + 4 =  \frac{15}{3} (x + 1)

y + 4 = 5x + 5

5x - y + 1 = 0

Therefore this is the equation of line AB.

Now, Finding the equation of line CD.

Given;

The points of line CD are; (1,1) and (4,10).

~ Using formula.

(y - y1) =  \frac{y2 - y1}{x2 - x1}(x - x1)

~ Keep all values.

(y - 1) =  \frac{10 - 1}{4 - 1} (x - 1)

~ Simplify it.

y - 1 = 3 x - 3

3x - y - 2 = 0

Therefore, 3x - y- 2 = 0 is the eqaution of line CD.

Use condition of parallel lines.

m1= m2

Slope of equation (i)

m1 =  \frac{ - coeff. \: of \: x}{coeff \: of \: y}

m1 =  \frac{ - 5}{ - 1}

Therefore, m1 = 5

Slope of second equation.

m2 =  \frac{ - coeff \: .of \: x}{coeff \: .of \: y}

m2 =   \frac{ - 3}{ - 1}

Therefore, m2 = 3.

Now, m1≠m2.

So, the lies are not parallel.

Check for perpendicular.

m1*m2= -1

3*5≠-1.

Therefore, they aren't perpendicular too.

So, they are neither.

HELP FAST PLEASE!!<br> FIND THE SURFACE AREO OF EACH RECTANGULAR PRISM
tatyana61 [14]

The surface area of the rectangular prism is 3668.94 m²

<h3>Calculating Surface area </h3>

From the question, we are to determine the surface area of the rectangular prism

Surface area of a rectangular prism is given by the formula,

Surface area = 2(lw + lh + wh)

Where l is the length

w is the width

and h is the height

From the given diagram,

l = 35.7 m

w = 25.5 m

h = 15.1 m

Putting the parameters into the formula, we get

Surface area = 2(35.7×25.5 + 35.7×15.1 + 25.5×15.1)

Surface area = 2(910.35 + 539.07 + 385.05)

Surface area = 2(1834.47)

Surface area = 3668.94 m²

Hence, the surface area of the rectangular prism is 3668.94 m²

For a sample size of 115 and a population parameter of 0.1,what is the standard deviation of the normal curve that can be used t
Helga [31]

Answer:

A) 0.028

Step-by-step explanation:

Given:

Sample size, n = 115

Population parameter, p = 0.1

The X-Bin(n=155, p=0.1)

Required:

Find the standard deviation of the normal curve that can be used to approximate the binomial probability histogram.

To find the standard deviation, use the formula below:

\sigma = \sqrt{\frac{p(1-p)}{n}}

Substitute figures in the equation:

\sigma = \sqrt{\frac{0.1(1 - 0.1)}{115}}

\sigma = \sqrt{\frac{0.1 * 0.9}{115}}

\sigma = \sqrt{\frac{0.09}{115}}

\sigma = \sqrt{7.826*10^-^4}

\sigma = 0.028

The Standard deviation of the normal curve that can be used to approximate the binomial probability histogram is 0.028
