Answer:
The approximate area of the regular pentagon is 423 sq.cm.
Step-by-step explanation:
Formula of area of regular pentagon =
P=Perimeter of pentagon
a=Apothem
Side of pentagon = 14.1 cm
Perimeter of pentagon =
Apothem=12 cm
Area of regular pentagon =
Hence the approximate area of the regular pentagon is 423 sq.cm.
Answer:
Step-by-step explanation:
Given function is h(t) = -16t² + 1500
a). For h(t) = 1000 feet,
1000 = -16t² + 1500
1000 - 1500 = -16t² + 1500 - 1500
-500 = -16t²
t² =
t =
t = 5.59 sec
b). For h(t) = 940 feet,
940 = -16t² + 1500
940 - 1500 = -16t² + 1500 - 1500
-16t² = -560
t² =
t =
t = 5.92 sec
c). For domain and range of the function,
When the jumper comes down to the ground,
h = 0
0 =-16t² + 1500
t² =
t =
t = 9.68 sec
Since, x-values on the graph vary from x = 0 to x = 9.68,
Domain : [0, 9.68]
Vertex of the quadratic function: (0, 1500)
Since, coefficient of the highest degree term is negative, parabola will open downwards.
Therefore, y-values of the function will vary in the interval y = 0 to y = 1500
Range: [0, 1500]
