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:
C. (x+3)^2 + (y-2)^2 = 225
Step-by-step explanation:
The equation of the circle is (x-h)^2 + (y-k)^2 = r^2
h=-3, k=2 and r=15
(x-(-3))^2 + (y-2)^2 =15^2
(x+3)^2 + (y-2)^2 = 225

Answer:
So possibilities of zeroes are:
Positive Negative Imaginary
1 1 2
3 1 0
Zeroes = -1.4549, 1.2658, 0.34457-1.0503i, 0.34457+1.0503i.
Step-by-step explanation:
Note: Descartes' Rule of Signs is used to find the signs of zeroes not the exact value.
The given function is
Degree of polynomial is 4 so number of zeroes is 4.
There are three sign changes, so there are either 3 positive zeros or 1 positive zero.
Now, put x=-x in f(x).
There is one variation in sign change, so there is 1 negative zero.
So possibilities of zeroes are:
Positive Negative Imaginary
1 1 2
3 1 0
Using graphing calculator the zeroes of given function are -1.4549, 1.2658, 0.34457-1.0503i and 0.34457+1.0503i.
