Answer:

46 terms

Step-by-step explanation:

a₁=b, a₂₁= bₙ, d₁=9, d₂=4

n=?

---------------

a₂₁= a₁+20d₁= a₁+20*9= a₁+180

bₙ= b₁+(n-1)d₂= a₁+4(n-1)

a₁+4(n-1)=a₁+180

4(n-1)=180

n-1= 180/4

n-1= 45

n=46

Find the length of BC.<br><br><br><br>Explain how you got it, please!<br>Thanks!
Vinvika [58]

Answer:

BC = 30.73

Here,

\sf \frac{AB}{BQ}  = \frac{CD}{DQ}

so first solve for QD

\sf \hookrightarrow \frac{32}{15}  = \frac{19.2}{DQ}

\sf \hookrightarrow 32(DQ)}  =19.2(15)

\sf \hookrightarrow 32(DQ)}  =288

\sf \hookrightarrow DQ =9

  • Hence, QD = 9

Now! <u>using Pythagoras theorem,</u>

  • CD² + BD² = BC²
  • 19.2² + (9+15)² = BC²
  • BC = √368.64+576
  • BC = 30.73499634
  • BC = 30.73 ( rounded to nearest hundredth )
