Answer:
see below
Step-by-step explanation:
the actual way of writing sin inverse is arcsine, not sin⁻¹
since the output of sin is from -1 to 1, the domain of arsince is from -1 to 1. This is different than 1/sin(x), whose domain is all real numbers. we now write sin⁻¹ to fit it on the tiny buttons on our calculators
Using the picture, we know (2x+6)+(5x-3)=24. Simplify to find x.
7x+3=24
7x=21
x=3
We know AB=2x+6, and x=3. Plug 3 in for x.
AB=2(3)+6.
AB=6+6
AB=12
Answer:
1. 32 inches = 81.28 centimeters
2.402 000 millimeters = 402 meters
3. 2.85 meters = 285 centimeters
4.2 kilometers= 2000000 millimeters
5. 71 meters = 0.071 kilometers
6. 8kg = 8000 g
7. 3000 g = 3 kg
8. 2.5 kg = 2500 g
9 850 mg = 9.85 g
10.75 dg = 1075 m
Answer: 22 students made the team this year
Step-by-step explanation:
Given : Total students tried out for the team = 40
After a week , 40% of students made the team, students made the team = 40% of 40
= 0.40 x 40
= 16
Remaining students = 40 - 16 = 24
After second week, students made the team = 25% of (Remaining students)
= 0.25 x 24
= 6
Total students made the team this year = 16+ 6= 22
