What trigonometric function represents the graph? (6 points)

a. f(x) = 4 sin(x − pi over 2 )

b. f(x) = 4 cos(x − pi over 2 )

c. f(x) = 4 sin(x − pi over 2 ) + 1

d. f(x) = 4 cos(x − pi over 2 ) + 1

Option A is correct.i.e,

Step-by-step explanation:

We are given with a graph .

A points from graph which satisfies it =

We check which equation satisfy points.

Option A:

Let,

we have

LHS = y = 0

LHS = RHS

Thus, This Option is correct.

Option B:

Let,

we have

LHS = y = 0

LHS ≠ RHS

Thus, This Option is not correct.

Option C:

Let,

we have

LHS = y = 0

LHS ≠ RHS

Thus, This Option is not correct.

Option D:

Let,

we have

LHS = y = 0

LHS ≠ RHS

Thus, This Option is not correct.

Therefore, Option A is correct.i.e,

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
