Suppose a Ferris wheel has a diameter of 68 m. The wheel rotates 12° each time a new passenger
is picked up. How far would you travel when the
wheel rotates 12°? Round to the nearest tenth
if necessary.
A 7.1 m
C 7.8 m
B 7.5 m
D 14.2 m

A. 7.1 meters

Step-by-step explanation:

12 ÷ 360 =

C = Dπ = 68π

= 7.120

Round down to 7.1

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
