Answer:
38
Step-by-step explanation:
38°
<BAY=52°
<YAC+<BAY=90°
<YAC= 38°
U(x)=-2x²+3
v(x)=1/x →→ range of (uоv)(x, BUT range (uov)(x = u(v(x)), then :
u(v(x)) = -2(1/x²) + 3 →→u(v(x)) = -2/x² + 3
The range of -2/x² + 3 = {x∈R/x≠0}
<span>==> 6(15+x) = 120
==> 15+x = 20
==> x = 5.
Therefore five new workers joined the crew.</span>
