Answer:
<em>∠B </em>= 65°
Step-by-step explanation:
Complementary angles are angles that add up to 90°. So if there is 90 total degrees - 25 degrees of <em>∠A, then ∠B </em>= 65°.
Answer:
Step-by-step explanation:
Anything that is multiplied greater than 1 will be greater than what the other factor is. You are correct!
Period of sin wave = 1/2
Period of parent sine function is 2π.
This means the x value of sine function (sin(x)) has to be divided by 4π to get a period of 1/2 because 2π/4π = 1/2
Thus, our function will be of the form:

Maximum Value = 10
Minimum Value = -4
Amplitude of the function = (Maximum Value - Minimum Value)/2
So, amplitude of the function is 7
Thus, the function will be of the form:

The function has a y-intercept other than zero, this means the function will be of the form:

The y-intercept is 3. This means for x=0, y=3. Using the values, we get:
Thus the equation of the sinusoidal function becomes:
2.95 =
