In circle R with m angle QRS= 90 and QR= 3 units find the length of arc QS round to the nearest hundredth
1 answer:
Answer:
4.71 units
Step-by-step explanation:
The formula for arc length =
2πr × θ/360
From the above question,
r = QR = 3 units
θ = angle QRS= 90 = 90°
The length of the arc is calculated as:
2 × π × 3 × 90/360
= 4.7123889804 units
Approximately to the nearest hundredth = 4.71 units

y increases as x increases
X^2 + 8x + 3
= (x + 4)^2 - 16 + 3
= (x + 4)^2 - 13 Answer.
You divide the + 8 by 2 to get the +4 and you then subtract 4^2 ( which is the -16).
