Which function r or s is the inverse function for function q?

a) the function r because the graphs of q and r are symmetrical about the y axis.

b) the function r because the graphs of q and r are symmetrical about the line y=x.

c) the function s because the graphs of q and a are symmetrical about the line y=x

d) neither function

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
