we are given

Firstly ,we can find equation in vertex form
so, we will complete x square



now, we can compare it with vertex form of equation

we can find h and k

so, vertex is

Answer:
See below
Step-by-step explanation:
Remember the quotient identity
, so you need to take the reciprocal of the sine value for the given angle in order to get the cosecant value for that same angle.
Answer: 85.13
Step-by-step explanation:
We know:
Circumference = 2*3.14r
Area of a circle = 3.14r²
We need to find the radius given the circumference before solving for the area:
32.7 = 2*3.14r
32.7/6.28 = 6.28r/6.28
r = 5.20700637
Now that we know the radius, we can plug it in to find the area:
A = 3.14(5.20700637)²
A = 3.14(27.1129153)
A = 85.134554
