You are standing next to a really big circular lake. You want to measure the diameter of the lake, but you don't want to have to

swim across with a measuring tape! You decide to walk around the perimeter of the lake and measure its circumference, and find that it's 400pi m.
What is the diameter d of the lake?

The diameter would be 400 because one of the two formulas to find a circumference is C= pi (D) so according to ur information, the diameter would be 400

A given line has the equation 10x+2y=-2.
Iteru [2.4K]

The equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

If two lines are parallel then their slopes are equal.

We have the following line:

10x + 2y = -2\\2y = -10x-2\\y = -5x-1

Thus, the slope of the line is -5.

Therefore a parallel line is of the form:

y = -5x + b

We replace the point (0,12)

12 = -5 (0) + b\\12 = b

Finally, the equation is of the form:

y = -5x + 12

Answer:

5x + y = 12
