Answer:
13.3
Step-by-step explanation:
f² = e² + g² - 2(e)(g)cos(F)
f² = 9² + 18² - 2(9)(18)cos(45)
f² = 175.8974029
f = 13.262631982
Answer:
Most kazoos are made from thermoplastics, which are more rigid and durable. Different types of plastics used to make the body of a kazoo include polypropylene and high-density polyethylene (HDPE). To make these materials easier to work with, fillers, which change the properties of the plastic, are often added.
For a
0 > -3(1) + 3 i.e. 0 > 0 (not true)
For b
1 > -3(-1) + 3 i.e. 1 > 6 (not true)
For c
2 > -3(2) + 3 i.e. 2 > -3 (true)
2 > 2(2) - 2 i.e. 2 > 2 (not true)
For d
3 > -3(0) + 3 i.e. 3 > 3 (not true)
Therefore, none of the ordered pairs makes both inequalities correct.
