Answer:
Your answer of option b is right.
Step-by-step explanation:
Given that a sinesoidal function has maximum 12 and minimum -6
Hence centre line would be average of these two.
Centre line is
i.e. f(x) = a sin (bx+c)+3
Since amplitude = 12-3 =9 we have a = 9
i.e. f(x) = 9 sin (bx+c)+3
Frequency is given as 3, period = 1/3
This gives b = 6pi
f(0) = y intercept =
9sin(c)+3 =3
This gives c=0
Hence correct equation is
Answer:
825.663706143591cm
Step-by-step explanation:
80cm × 4 = 320cm
100cm × 3 = 300cm
The radius is 40
40 × 2 = 80cm
Circumference is πd
π80 = 251.327412287183
÷ 2 = 125.663706143591cm
In total
320 + 300 + 80 + 125.663... =
825.663706143591cm

Answer: -7a+6c+3
Answer:
C
Step-by-step explanation:
× 45 = 4 × 9 = 36 ← Marlina's books
× 45 = 2 × 15 = 30 ← Daniel's books
36 - 30 = 6
Marlina has 6 more novels than Daniel → C
