Answer:

2.)4n>(n/2)^2

3. (The problem isn't clear)

4.)n^2+2n-3=129

5.)n-5=171

Step-by-step explanation:

2.)

4n(four times the number) >(larger than) (n/2)^2 (half the number squared)

4.)

Sum=addition

n^2 (number squared) +2n (twice the number)-3=129

5.)

N(unknown number of pages) -5(amount of pages already read)= 171(the number of pages it took her to finish)

please help as soon as possible-Solve the right triangle shown in the figure. WIll mark brainliest to first correct answer
Dennis_Churaev [7]

Answer:

option a is the correct answer; ∠A = 68°, ∠B = 22°, AB = 2.9 cm

Step-by-step explanation:

From my understanding, we have to find angle A, angle B and side AB.

<u>Step 1: Find side AB</u>

<em>AB can be solved through the Pythagoras theorem.</em>

<em>c² = a² + b²</em>

<em>c² = 2.7² + 1.1²</em>

<em>c² = 8.5</em>

<em>c = √8.5</em>

c = 2.9 cm

<u>Step 2: Find angle A</u>

<em>Angle A can be found through tan formula</em>

<em>tan (angle) = opposite/adjacent</em>

<em>tan (angle A) = BC/AC</em>

<em>tan (angle A) = 2.7/1.1</em>

<em>Angle A = tan inverse (2.7/1.1)</em>

Angle A = 68°

<u>Step 3: Find angle B</u>

<em>All 3 angles of a triangle are equal to 180°</em>

<em>Angle A + Angle B + Angle C = 180°</em>

<em>68 + B + 90 = 180°</em>

Angle B = 22°

option a is the correct answer; ∠A = 68°, ∠B = 22°, AB = 2.9 cm

Please help! I am supposed to write a recursive and an explicit function for the geometric sequence but this one is really frust
makkiz [27]

Step-by-step explanation:

Initially, there's only 1 letter.

Tania sends the letter to 4 friends.

Each friend sends a letter to 4 more friends (4 × 4 = 16).

Each of those friends sends to 4 more friends (16 × 4 = 64).

The pattern is 1, 4, 16, 64, etc.

This is a geometric sequence.  The first term is 1 and each term is 4 times the previous term.

a₁ = 1

aₙ = 4 aₙ₋₁

The explicit formula is:

aₙ = 1 (4)ⁿ⁻¹
