Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
Step-by-step explanation:
But that's what I say personally
Sqrt 73 = 8.54 (thats rounded to nearest hundredth)
P = $650
r = 5% annually = 0.05
t = 1 month = 1/12 year
SI = Prt = 650 * 0.05 * 1/12 = $2.7
Answer:
48in^3
Step-by-step explanation:
volume of rectangular prism formula: L*W*H
lets plug in values for:
l=length(3)
w=width(2)
h=height(8)
so
3*2*8=48
48in^3
Hope this helps!
Answer:
1, -6
Step-by-step explanation:
Since there are alike numbers, add them together.
4x+x= 5x
Now the function is: f(x)= +5x-6
The function is in +bx+c form.
So find the factors of a x c = b.
Factors of -6(a) that fits (b)5 is (-1,6).
Then you just factor it:
f(x)= +5x-6
(x-1)(x+6)
x-1= 0 x+6=0
+1 +1 -6 -6
x=1 x=-6
Those are the real zeroes: 1, -6
