Answer:
4, 8, 16, 32, 64
Step-by-step explanation:
The nth term of a geometric sequence is
= a₁
Given
a₇ = 256 and a₁₀ = 2048 , then
a₁ 
= 256 → (1)
a₁ 
= 2048 → (2)
Divide (2) by (1)
= 
r³ = 8 ( take the cube root of both sides )
r = ![\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D)
= 2
Substitute r = 2 into (1)
a₁ × 
= 256
a₁ × 64 = 256 ( divide both sides by 64 )
a₁ = 4
Then
a₁ = 4
a₂ = 2a₁ = 2 × 4 = 8
a₃ = 2a₂ = 2 × 8 = 16
a₄ = 2a₃ = 2 × 16 = 32
a₅ = 2a₄ = 2 × 32 = 64
Answer:
C
Step-by-step explanation:
You can look them up in the graphs.
f(2) means "where is the blue graph when x=2?", and you can see it is at y=0.

<h3>
Answer: approximately 5.1724%</h3>
Work Shown:
2 hrs, 45 min = 120 min + 45 min = 165 min
2 hrs, 54 min = 120 min + 54 min = 174 min
A = estimated value = 165
B = true value = 174
C = percent error
C = 100*( |A - B| )/B
C = 100*( |165-174| )/174
C = 100*( | -9 | )/174
C = 100*9/174
C = 900/174
C = 5.1724% which is approximate
Answer:
60 miles.
Step-by-step explanation:
In 6 hours a train travelled 360 miles
So
In 1 hour a train travelled 360/6 = 60 miles .
Hope it helps have a great time ❤
