A geometric sequence has a4 = 4 and a5 = 7. What is a1 ? Your answer​
svetlana [45]

Answer:

  • 4⁴/7³ or 256/343

Step-by-step explanation:

<u>Given GP with </u>

  • a₄ = 4
  • a₅ = 7
  • a₁ = ?

<u>Let the common difference is r, then</u>

  • a₅ = a₄r
  • a₁r³ = 4
  • a₁r⁴ = 7

<u>Solve for r and then a₁:</u>

  • 4r = 7 ⇒ r = 7/4
  • a₁(7/4)³ = 4

AlexFokin [52]
Recall the secant-tangent theorem, and you have
EA^2 = EC*CD
12^2 = 8*(x+10)
and now ED = EC+CD = 8+x+10

Need t in degrees not just solve for t
Inessa [10]

An exterior angle is equal to the sum of the two opposite inside angles.

T + 31 = t + t-29

Simplify:

T + 31 = 2t -29

Add 29 to both sides:

T + 60 = 2t

Subtract 1t from both sides:

T = 60
