<h3>What is geometrical series?</h3>
A geometric series is the collection of an unlimited number of terms with a fixed ratio between them.
Given the value of a₁=9 and the value of
. Therefore, the value of a₅ can be written as,
a₂ = -3(a₁) = -3(9) = -27
a₃ = -3(a₂) = -3(-27) = 81
a₄ = -3(a₃) = -3(81) = -243
a₅ = -3(a₄) = -3(-243) = -729
Hence, the value of a₅ is -729.

Answer:
JL = 14
Step-by-step explanation:
N represents the center of the rhombus
Then
N is the midpoint of the diagonal (line segment) JL
Then
JL = 2 × NL
= 2 × 7
= 14

Correct answer is 4:13 am
Answer:
27
Step-by-step explanation:
Let the radius of the smaller sphere is x.
Then the radius of the larger sphere is 3x.
The volume of a sphere is given by
Hence, the volume of the smaller sphere is
And the volume of the larger sphere is
Divide both volumes, we get
Hence, the volume of the smaller sphere is 27 times smaller than the volume of the larger sphere.
