Answer:
Step-by-step explanation:
Let the equation of the cosine function is,
y = Acos(Bx)
From the graph attached,
A = Amplitude =
= 1
B =
B =
B =
B = 4
Therefore, equation of the cosine wave given in the graph will be,
y = 1.Cos(4x)
y = Cos(4x)
Answer:
1
Step-by-step explanation:
The correct answer for the question shown above is the second option (Option b), and the option cwhich is:
b) x = -1/16y^2
c) y=-1/16x^2
The explanation is shown below:
The focus of a parabola is (h,k+1/4a), then, you have:
h,k= (0,0)
1/4a=1/4(-1/16)
Then, you obtain:
1/4a=-4
Therefore, the focus of the equation of the parabola x = -1/16y^2 and the parabola y=-1/16x^2 <span>is F(0-4)

So, as you can see, the correct answer is the options mentioned before, the option b and the option c.
Answer:
Step-by-step explanation:
Let r represent the radius of the circle (in cm) and
let C represent the circumference of the circle (in cm).
First solve the equation for 'r' using circumference formula
Circumference of circle formula is
Solve for r, divide both sides by 2pi
the function g determines the radius of the circle in cm
So we replace 'r' with g(C), where C is the circumference
