Step-by-step explanation:
A1 = 9
r = 2/3
An = ar^{n - 1}
An = 9.(2/3)^{n - 1}
Option → C
Answer:
Step-by-step explanation:
Part A: Yes
Proof:
a) Basic Proportionality Theorem (also Side Splitter Therom) which states that: "If a line (AB) intersects two sides (PQ and PR) at two distinct points and is parallel to the third side (QR), therefore is divid these sides proportionally."
b) Therefore, according to SSS Similarity Theorem: "If the sides of the two triangles are proportional, then the two triangles (PQR and PAB) are similar
Part B: The line segment AB corresponds to line segment QR because the triangles are similar and these two sides are parallel
Part C: Angle A (or Angle PAB) corresponds to Angle Q because line segment AB corresponds to QR and line segment PA corresponds to line segment PQ.

Answer:
2, 0, -2, -4
Step-by-step explanation:
an = 4 − 2n
a1 = 4 - 2(1) = 2
a2 = 4 - 2(2) = 0
a3 = 4 - 2(3) = -2
a4 = 4 - 2(4) = -4
Jacob used 1/7 of a liter
of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to
mixed fraction
=> x = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.
