(8 × 100000) + (5 × 10000)
800000 + 50000
850000
Answer:
f(x) = 5*cos(5*x) + 2
Step-by-step explanation:
A general cosine function is written as:
f(x) = A*cos(ω*x) + M
where:
A is the amplitude
M is the midline
ω is the angular frequency.
In this case we know that:
The amplitude is 5, then A = 5
The midline is 2, then M = 2
The period is 2*pi/5
The relation between the angular frequency ω and the period T is:
ω = 2*pi/T
Then if the period is T = 2*pi/5, replacing that in the above equation we find that:
ω = 2*pi/T = 2*pi/(2*pi/5) = 5
ω = 5
Then the function is:
f(x) = 5*cos(5*x) + 2
