Area = pi * r^2
Area = pi * 12^2 = 452.39 square units
Circumference = 2(pi) * r
2 * pi * 12 = 75.40 units
<span>23 + 3 + 5 - 2 + 5 + 3 - 1 + 1 =
37
Hope this helps :))</span>
<span>8i is:
z = 8(cos(90) + i sin(90)) ; now take the 1/3 power of it.
</span><span>When we take this to a normal integer power of 3 we get:
z^3 = 8^3(cos(90*3) + i sin(90*3)) right? its the same for rational exponents as well.
</span>
<span>z^(1/3) - 2(cos(90/3) + i sin(90/3))
</span>
<span>90/3 = 30; the cos(30)=sqrt(3)/2 and the sin(30) = 1/2
2(sqrt(3)/2 + i 1/2) = sqrt(3) + 1i should be one of the cube roots.
</span>
<span>(sqrt(3) + i)^2 = 2 +2sqrt(3) i
(sqrt(3)+i) (2 +2sqrt(3)i
2sqrt(3) + 6i +2i -2sqrt(3) = 8i</span>
Answer:
A and D
Step-by-step explanation:
Since a (1/3) is less than 1, it is vertically compressed. The -7 is outside of the parenthesis so it is shifting down.
Answer:
(-4, 1)
Step-by-step explanation:
all you have to do is see where x is -4 and where the parabola crosses when x is -4
