Answer:
6
Step-by-step explanation:
The period of a sinusoidal function in the form a * cos (b (x + h)) + m is
. Therefore, we can see that "b" in g(x) is 1/3 and 1/3 substituted into
is 2
/1/3 which is 6
.
Answer:
D α H
k = D/H
k = 3.50
Step-by-step explanation:
Amount paid, D is directly proportional to the number of hotdogs, H
D = $3.50 per hot dog
D = $3.50 is directly proportional to 1 hotdog
Hence,
D α H
D = kH
k = proportionality constant
H = 1
3.50 = k
k = 3.50
k = D/H
