2. The beam of a lighthouse can be seen for up to 20 miles. You are on a ship that is 10 miles east and 16 miles north of the li
Oksanka [162]

Answer:

<em>The person on the ship can see the lighthouse </em>

Step-by-step explanation:

<u>The Circle Function </u>

A circle centered in the point (h,k) with a radius r can be written as the equation

(x-h)^2+(y-k)^2=r^2

Any point (x,y) can be known if it's inside of the circle if

(x-h)^2+(y-k)^2\leq r^2

The question is about a beam of a lighthouse than can be seen for up to 20 miles. If we assume the lighthouse is emitting the beam as the shape of a circle centered in (0,0), then its radius is 20 miles. Thus any person riding a ship inside the circle can see the lighthouse. This means that

x^2+y^2\leq 20^2

x^2+y^2\leq 400

The ship's coordinates respect to the lighthouse are (10,16). We should test the point to verify if the above inequality stands

10^2+16^2\leq 400

356 \leq 400

The inequality is true, so the person on the ship can see the lighthouse

ruslelena [56]

If Jackson went to the movies and payed $7 initially for his ticket and then payed $2 for each box of candy that he buys, then the equation could look like this: y = 2x + 7, where y represents the total cost and x represents the number of boxes of candy Jackson buys.
