Answer:
a(10) = 3^9 = 19683
Step-by-step explanation:
In this sequence each new term is equal to 3 times the previous term. Thus, 3 is the common ratio. The first term is 1.
The general formula for the nth term of a geometric sequence i
a(n) = a(1)*r^(n -1), where r is the common ratio.
Here, a(n) = 1*3^(n - 1), and so
the 10th term is
a(10) = 1*3^(10 - 1), or
a(10) = 3^9 = 19683
Answer:
Option B.)
Step-by-step explanation:
Just took the test and got 100% :]
His investment would be B.$5,700
Reasoning:
1400 x 3 = 4200
500 x 3= 1500
1500+4200= 5700
Answer:
8
Step-by-step explanation:
1/2 goes to 3/4.. 5/8 goes to 3/4 as well, and both of them together would be 1
Distance between two points = √[( x₂ - x₁)² + (y₂ - y₁)²]
∴ distance between C and D = √[(x of C - x of D)² + (y of C - y of D)²]
= √[( 5 - 2)² + (6 - 2)²]
= √[( 3)² + (4)²]
= √(9 + 16)
∴ distance between C and D = 5 units
