Answer:
The nth term of the geometric sequence 7, 14, 28, ... is:
Step-by-step explanation:
Given the geometric sequence
7, 14, 28, ...
We know that a geometric sequence has a constant ratio 'r' and is defined by
where a₁ is the first term and r is the common ratio
Computing the ratios of all the adjacent terms
The ratio of all the adjacent terms is the same and equal to
now substituting r = 2 and a₁ = 7 in the nth term
Therefore, the nth term of the geometric sequence 7, 14, 28, ... is:
Answer:
CA ≈ 3.1 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = 
= 
= 
( multiply both sides by CA )
CA × tan40° = 2.6 ( divide both sides by tan40° )
CA = 
≈ 3.1 ft ( to the nearest tenth )
Answer: 52 Inches
Step-by-step explanation:
Small Rectangle Perimiter = 26
Rectangle = 4x the smaller rectangle
26*4= 104
Answer:
A =256 mm^2
Step-by-step explanation:
The perimeter of a square is given by the formula
P = 4s where s is the length of a side
64 = 4s
Divide each side by 4
64/4 =4s/4
16 = s
To find the area of a square, use the formula
A =s^2
A = 16^2
A =256 mm^2
