Answer:
(A)
Step-by-step explanation:
We assume the constant A is different than 0
We notice that the graph of the function intercepts the x-axis when x = -0.5
we know that cos(x) = 0 when x = π/2 or x = -π/2
thus, or
then or
so
Answer:
y = -3x + 8
Step-by-step explanation:
The slope of a perpendicular line to the original equation is the opposite reciprocal of the slope of the original equation. This makes the opposite reciprocal -3, so the slope of the perpendicular line is -3.
Now that we have found the slope, we will put it into the formula for slope, y = mx + b. This results in getting y = -3x + b.
We know the values for x and y, (1,5) respectively. Plug these values into y = -3x + b.
5 = -3(1) + b
b = 8
This means that 8 is your y intercept and goes into place for b
Therefore, your resulting equation is y = -3x + 8
Answer:
Option 2nd is correct that is
Step-by-step explanation:
We have given the vertices of a parabola
General equation of parabola is:
Here, (h,k) is vertex of the parabola
Here, h=1 and k=2 and a=1
On substituting the values in the general equation of the parabola we get:
Therefore, option 2nd is correct.
