Answer:
D
Step-by-step explanation:
because 4x4=16..........
The light's coverage area is given mathematically as i.e. Area=
Given that a lighthouse casts a revolving beam of light as far as they peir and asked the area is covered.
The revolving beam of light covers the whole space i.e entirely 360°
I.e. it forms a circle-like region
Area of circle =
{ where r is the radius of circle}
Let's assume the distance traveled by light as "d"
as it forms a circular region, it forms a circle of radius "d"
Mathematical connection i.e. area of the region
⇒area of circular region=
{where d is the radius of region}

Step-by-step explanation:
they are both linear functions. A function is linear when the degree on X is equal to 1
C has no line segments depending on the font.
The sum of angles in a triangle is 180 drgrees.
From the picture I see that in the triangle UVW has angle U =90 degees, angle V=71 degrees so
W= 180-90-71= 19 drgrees
