Answer:

Point is (0,-2) and slope is m=-5, equation is y-y1=m(x-x1), plug and chug

13. m=-5 point is (0,-2)

y-y1=m(x-x1)

y-(-2)=-5(x-0)

y=-5x-2


16. m=12 point is (0,4/5)

y-y1=m(x-x1)

y-(4/5)=12(x-0)

y=12x+4/5


hope this helps

The area of the semicircle is A = 1187.9 cm².

<h3>What is the area of a circle?</h3>

The area of a circle with a radius of r is A = πr².

Given that, the diameter of the semicircle is 55 cm.

The radius of the semicircle is,

r = 55/2

The area of a semicircle is given by,

A = (1/2)πr²

Substitute the values,

A = (1/2)π(55/2)²

A = 1187.9

Hence, the area of the semicircle is A = 1187.9 cm².
