The missing justification in the proof is
<span>B) Substitution property of equality
The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.
Answer:
output = 23
Step-by-step explanation:
x = -4
f(x) = 3ǀ2x - 1ǀ + x
f(x) = 3ǀ2(-4) - 1ǀ + (-4)
f(x) = 3ǀ2(-4) - 1ǀ - 4
f(x) = 3ǀ-8 - 1ǀ - 4
f(x) = 3ǀ-9ǀ - 4
f(x) = 3(9) - 4
f(x) = 3(9) - 4
f(x) = 27 - 4
f(x) = 23

Answer:
k=13.8
Step-by-step explanation:
Given function:
- 2.5k+47.4=81.9
- to find k..
<u><em>Subtract final and middle value:</em></u>
<em><u>Divide by 2.5:</u></em>
Therefore, k=13.8..
