Answer:

Step-by-step explanation:

$\text{Put the coordinates of the given point A(2, 3)}\\\text{to the equation of a line}\ kx-2y+k=0:\\\\A(2,\ 3)\to x=2,\ y=3\\\\(k)(2)-(2)(3)+k=0\\2k-6+k=0\qquad\text{add 6 to both sides}\\2k+k=6\\3k=6\qquad\text{divide both sides by 3}\\\boxed{k=2}$

Find the surface area of the hexagonal prism

arsen [322]

Answer:

$4,636.8 \: {in}^{2}$

Step-by-step explanation:

Surface area of the hexagonal prism

= Area of base * Height

= 6*Area of one triangle *height

$= 6( \frac{1}{2} \times 8 \times 6.9) \times 28 \\ \\ = 6(4 \times 6.9)28 \\ \\ = 6 \times 27.6 \times 28 \\ \\ = 4,636.8 \: {in}^{2}$

Ariel was told the x intercept and the y intercept of a line with a positive slope. Yet, it was impossible for Ariel to find the

alexdok [17]

A line has the following standard equation form:

y = m x + b

where m is the slope and b is the y intercept

So if Ariel cannot find the slope, then this would only mean that m = 0, there is no slope. And hence the line is either a straight vertical line or straight horizontal line.

Answer:

<span>There is no slope</span>
