32 students would be on the trip. What I did to solve it was a proportion. 8students/ 3 chaperones= x students/12 chaperones.
8*12= 96 and 96/3=32. Therefore 32 students were on the trip.
(csc x-1)(csc x+1)=csc²x-1²=csc²x-1=(1/sin x)² -1=1/sin x² - sin²x/sin²x=
=(1-sin²x)/sin² x = cos² x/ sin² x = (cos x/sin x)²= (cot x)²
The height of the tree is 42.
Answer:
x=1, x=8
Step-by-step explanation:
4x2−36x+32=0
Step 1: Factor left side of equation.
4(x−1)(x−8)=0
Step 2: Set factors equal to 0.
x−1=0 or x−8=0
(+1) (+8)
x=1 or x=8
