Answer:
11.8cm²
Step-by-step explanation:
The area of the regular pentagon is expressed as;
A = pa/2
p is the perimeter of the pentagon
a is the apothem
Since p = 5s
s is the side length, hence;
A = 5sa/2
Get the side length s;
central angle = 360/5
central angle = 72degrees
angle in the right angle triangle =72/2 = 36degrees
Using SOH CAH TOA
sin 36 = x/2
x = 2sin36
x = 1.1755
s = 2x
s = 2.35cm
Get the area
A = 5(2.35)(2)/2
A = 5(2.35)
A = 11.8cm²
Hence the area of the regular pentagon is 11.8cm²
The true statements about the functions are:
- g(x) has the maximum greatest value.
- h(x) has a range of all negative numbers.
<h3>How to determine the true statements?</h3>
The complete question is in the attached image
From the image, we have:
- g(x) has the greatest maximum value of 7 1/2
- All the values of h(x) are negative
- All the values of f(x) are positive
This means that the true statements about the functions are g(x) has the maximum greatest value and h(x) has a range of all negative numbers.

Answer:
7
Step-by-step explanation:
I like to work liter volume problems in terms of decimeters. 1 dm = 10 cm, and 1 dm³ = 1 L, so the tank is 3 dm by 4 dm by 3 dm = 3×4×3 dm³ = 36 L.
36 liters will support 36/5 = 7.2 platies.
7 platies can be kept in the aquarium.
