Answer:

start with -29, multiply each term by 3

start with 90, multiply each term by 0.2

start with 67 and multiply each term by 2

The colony has 8576 cells after 7 minutes

Step-by-step explanation:

The pattern for the first part of Q2 is multiply each term by 3.

-29, -87, -261, -783... start with -29, multiply each term by 3

The pattern for the second part of Q2 is multiply each term by 0.2.

90, 18, 3.6, 0.72... start with 90, multiply each term by 0.2

The pattern for the third part of Q2 is multiply each term by 2

start with 67 and multiply each term by 2

The colony has 67×2×2×2×2×2×2×2= 8576 cells after 7 minutes

The following is an incomplete paragraph proving that the opposite sides of parallelogram ABCD are congruent:

Setler [38]

Answer:

The sentence which accurately completes the proof is: "Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem." ⇒ 2nd answer

Step-by-step explanation:

Let us revise the cases of congruence

SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ
ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ
AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ
HL ⇒ hypotenuse leg of the 1st right Δ ≅ hypotenuse leg of the 2nd right Δ

In Parallelogram ABCD

∵ Segment AB is parallel to segment DC

∵ Segment BC is parallel to segment AD

- Construct diagonal A C with a straightedge

In Δs BCA and DAC

∵ AC is congruent to itself ⇒ Reflexive Property of Equality

∵ ∠BAC and ∠DCA are congruent ⇒ Alternate Interior Angles

∵ ∠BCA and ∠DAC are congruent ⇒ Alternate Interior Angles

- AC is joining the congruent angles

∴ Δ BCA is congruent to Δ DAC by ASA Theorem of congruence

By CPCTC

∴ AB is congruent to CD

∴ BC is congruent to DA

The sentence which accurately completes the proof is: "Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA) Theorem."
