Answer:
hello :
note : secy = 1 / cosy
tany = siny /cosy
sin y+cos y+tan y sin y = sin y+cos y+( siny /cosy)sin y
= ( siny cosy + cos²y + sin²y) / cosy
= (siny cosy +1) / cosy......because : cos²y+sin²y =1
= (siny cosy) / cosy + 1 / cosy
= (siny/cosy) × cosy + 1/cosy
sin y+cos y+tan y sin y = tany cosy + secy
I can’t graph it but here’s the inequality:
t = temp.
t < 3.5.

Step-by-step explanation:ik
1. To the question whether it is a good idea to design a drink can from a solid nonmetal, the answer is <u>No, because nonmetals lack luster</u>.
<h3>The Luster in Nonmetal</h3>
Non-metals do not have luster because they cannot reflect light from their surface with their dull appearances. Diamond and iodine are two exceptions to lustrous non-metals.
2. The reason it is not a good idea designing a drink can from a solid nonmetal is <u>No, because nonmetals are brittle.</u> Generally, solid nonmetals are known to be <u>dull and brittle</u>. They can easily break into pieces.
Thus, non-metals are <u>not ductile or malleable</u>.
