Answer:
A
Step-by-step explanation:
Given a sinusoidal function (sine function or cos function) in the form
y = A Cos (Bx), we can say that A is the amplitude.
<em>Amplitude defines the function's maximum and minimum.</em>
The maximum of this form of function is A and the minimum is -A.
The function given is y = -Cos(8x), so A is -1
Thus, maximum value is 1 and minimum value is -1.
Correct answer is A
Use trigonometry.
sinQ = 14/50 = 0.28
-> angle Q = sin^-1(0.28) = approx 16 degrees
-> cosQ = A/H -> cos16 = PQ/50
=> PQ = 50*cos16 = approx 48.06
So yea.
The answer is C. x=3 2(3)^3=54
Answer:
The slope is 1/2
i believe
Step-by-step explanation:
Use the rise/run method
D∩E=D This is because since D is a subset of E then the elements they will have in common are the elements in D and D is not a null set
