Answer:
with what may I help you with
Step-by-step explanation:
You are changing the sign on one so to keep an equilibrium you change the other sign too
Tan42°=x/35
x=35tan42° units
x≈31.51 units (to nearest hundredth of a unit)
(secx + tanx)^2
<span>secxsecx + secxtanx + secxtanx + tanxtanx
</span>secxsecx + 2secxtanx + tanxtanx
tanxtanx + 1 + 2secxtanx + tanxtanx
2tanxtanx + 1 + 2secxtanx <span>
The expression (secx + tanx)2 is the same as </span>1 + 2tan2x + 2secx tanx. The answer is letter D.
Answer:
Step-by-step explanation:
4x+1.3=-7.9
4x=-1.3-7.9
4x=-9.2
