Answer:
98.8 cm²
Step-by-step explanation:
Hi there!
where P is the perimeter of the pentagon and a is the apothem (the line going from the center of the pentagon one edge)
<u>1) Find the perimeter</u>
where l is the side length
Plug in the side length 7.6 cm

Therefore, the perimeter of the pentagon is 38 cm.
<u>2) Find the area</u>
Plug in the perimeter (38) and the apothem (5.2)

Therefore, the area of the pentagon is 98.8 cm².
I hope this helps!
Answer:
Slope: -1.4
y = -1.4x - 0.49
Step-by-step explanation:
Slope: dy/dx = 2x
x = -0.7
dy/dx = -1.4
Equation of tangent:
y = mx + c
y = -1.4x + c
When x = -0.7, y = 0.49
0.49 = (-1.4)(-0.7) + c
c = -0.49
y = -1.4x - 0.49
4/14 because you multiply each number by 2
