Answer:

Step-by-step explanation:

2) 3x⁴ - 25x³ + 27 = 3(2)⁴ - 25(2)³ + 27 = 3*16 - 25*8 +27 = 48 - 200 + 27

= -125

3) 20s⁴ + 24s³ + 4s = 20(1)⁴ + 24(1)³ + 4(1)

= 20 + 24 + 4 = 48

4) 6m⁴ - 4m +20 = 6(4)⁴ - 4(4) +20

= 6*256 - 16 + 20= 1536 - 16 + 20

=1540

5) - 7p⁴ - p + 9 = -7(-2)⁴ - (-2) +9 = -7*16 + 2 +9 = -112 + 2 + 9 = - 101

6) 6a⁷ - a³ + a = 6(-1)⁷ - (-1)³ + (-1) = 6*(-1) - (-1) - 1 = -6 + 1 - 1 = -6

Find the length of AB AB=

Elden [556K]

Answer:

AB ≈ 5.59 m

Step-by-step explanation:

The arc AB is calculated as

AB = circumference of circle × fraction of circle

= 2πr × $\frac{40}{360}$ ( r is the radius )

= 2π × 8 × $\frac{1}{9}$

= 16π ÷ 9 ≈ 5.59 m ( to the nearest hundredth )
