Find the distance between the point (3, 5) and a line with the equation 5 x - 3 y + 10 = 0
timama [110]

The distance between the point (3, 5) and a line with the equation 5x – 3y + 10 = 0 will be 10 / √(34) units.

<h3>What is the distance between a point and a line?</h3>

Let (x₁, y₁) be the point and ax + by + c = 0 be the line.

Then the distance between a point and a line will be

\rm d = \dfrac{|ax_1 + by_1 + c|}{\sqrt{a^2 + b^2}}

The point (3, 5) and a line with the equation 5x – 3y + 10 = 0.

Then the distance between them will be

\rm d = \dfrac{|5 *3 - 3 *5 + 10|}{\sqrt{5^2 + (-3)^2}}\\d = \dfrac{10 }{\sqrt{34}} \ units

A concrete stepping stone measures 20 inches square. What is the area of 30 such tiles?
ratelena [41]
A single stepping stone as you have said is 20 inches sqaure. This means that it has an area of 20.

All you would need to do then is multiply 20 by 30 to get the area of thirty tiles. The result of this would be 600.

If you mean one side of the stepping stone is 20 inches then you would multiply 20 by 20 to get the area of one, since that would be multiplying length times width (the area formula). The area of one would result in 400 and you would then multiply this by the thirty tiles (400 times 30) to get 12000.

I don’t understand at all
mariarad [96]
A=1/2ab
Replace the variables with their value
15=1/2(3/2)b
Multiply 1/2 and 3/2
\frac{1}{2}  \times  \frac{3}{2 }  =  \frac{3}{4}
15=3/4b
Divide 3/4 on both sides
15/(3/4) is the same thing as
\frac{15}{1 }  \times  \frac{3}{4}  =  \frac{45}{4}
45/4=b

Which answer is the best estimate of the correlation coefficient for the variables in the scatter plot.
Sholpan [36]

Answer:

These points are hard to graph, so I have a website that you can go to instead and all you have to do is put in the points and then once you're done type in correlation coefficient and then type in (A,B,C, D, E, etc.) and you'll be given the correlation coefficient. I put a picture with my attempt at graphing. I hope this helps, sorry I couldn't graph it for you

The site is: geogebra and it is a graphing calendar: https://www.geogebra.org/graphing
