A regular heptagon has a side of 13.9 and an apothem of 14.4. Find the area of the heptagon. Round your answer to the nearest WHOLE NUMBER.

Step-by-step explanation:

Given that,

A regular heptagon, a heptagon has 7 sides and since it is a regular heptagon, then, it has equal sides

n = 7, number of sides

Each sides of the heptagon has a length of 13.9

s= 13.9

The apothem is 14.4

Apothem is a line from the centre of a regular polygon at right angles to any of its sides.

r = 14.4

The area of a regular heptagon can be calculated using

Area = ½ n•s•r

Where n is the number of sides

s- is the length of the sides

r Is the apothem

Then,

A = ½ × 7 × 13.9 × 14.4

A = 700.56 square units

To the nearest whole number, I.e no decimal points

A = 701 Square units

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
