Answer:
D) 20,800,000
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
m=(y-y1)/(x-x1)
Points are (5,2) and (4,1)
m= (2-1)/(5-4)= 1/1= 1
m=1 to replace ? mark
A regular dodecagon is a polygon with 12 equal sides.
Length of each side = 108/12 = 9 cm.
Length of the apothem = (9/2)/tan 15 = 9/2tan 15 = 16.79 cm
Area of each triangle = 9/2(16.79) = 75.57 cm^2
Therefore, area of the dodecagon = 12(75.57) = 906.9 cm^2
Answer:
A)94.5 cm
Step-by-step explanation:
height = 9cm
Base 1 = 5cm
Area of a Trapezoid = 1/2 × (b1 + b2)h
h = 9cm
b1 = 5cm
b2 = (9 cm + 5cm + 2cm) = 16cm.
Area of Trapezoid
= 1/2 (5 + 16) × 9
= 1/2 × 21 × 9
= 94.5 cm
Option A is the correct answer
The ordered list of sequences from least to greatest common difference is:
Sequence A
Sequence C
Sequence B
Step-by-step explanation:
We will find the common difference of each sequence first.
So,
<u>Sequence A:</u>
5, 7, 9, 11
Here,
The common difference is 2.
<u>Sequence B:</u>
34, 43, 52, 61,
The common difference is 9.
<u>Sequence C:</u>
-9, -4, 1, 6,
The common difference is 5.
The ordered list of sequences from least to greatest common difference is:
Sequence A
Sequence C
Sequence B
