<h2>the given complex number is 256(cos 280° +¡ sin)=4⁴(cos(4×70°) <em>i</em><em> </em><em>s</em><em>i</em><em>n</em><em>(</em><em>4</em><em>×</em><em>7</em><em>0</em><em>°</em><em>)</em><em> </em></h2>
The answer to the question is 3. $29.40
#1. 5(t+3)=-10
5t+15=-10
5t=-25
t=-5
#2. -(c-10)=0
-c+10=0
c=10
#3. -10(s+3)=-15
-10s-30=-15
-10s=15
s=-3/2
#4. 5(f-5)=-60
5f-25=-60
5f=-35
f=-7
#5. -5(2t+2)=-70
-10t-10=-70
-10t=-60
t=6
#6. 4(3w+2)/3=-6
12w+8=-18
12w=-26
w=-13/6
#7.Substitute the °C with -8
Equation:
5/9(F-32)=-8
divide both sides by 5/9
F-32= -14.4
add 32 to both sides
F=17.6
Answer: -8°C in °F is approximately 18°F.
BTW, to get the degree sign, it's option+shift+8.
