Answer:
The volume of the cylinder is 792
Step-by-step explanation:
3.14*6^2*7= 791.68 then when you round it up to the nearest whole number it's 792
<h2>
Answer: a = ¹/₂ (4 + b)</h2>
<h3>
Step-by-step explanation:</h3>
To solve for 'a' we have to make it the subject of the equation. Since there are two unknowns ('a' & 'b'), we won't get a numerical value of 'a', but an expression in terms of the second unknown 'b'.
Since 2a - b = 4 <em> [add 'b' to both sides]</em>
then 2a = 4 + b <em>[divide both sides by 2 = multiplying by ¹/₂]</em>
a = ¹/₂ (4 + b)

The answer to your question is below
Step-by-step explanation:
2.
Just find the prime factors of 128 and simplify
![\sqrt{-2^{7}} = \sqrt{-2^{6} 2} = 2^{3}i \sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B-2%5E%7B7%7D%7D%20%3D%20%5Csqrt%7B-2%5E%7B6%7D%202%7D%20%3D%202%5E%7B3%7Di%20%5Csqrt%7B2%7D)
![8i\sqrt{2}](https://tex.z-dn.net/?f=8i%5Csqrt%7B2%7D)
3.-
Get the square roots and simplify
3i + 4i
7i
4.- None of the choices is equal to one, because the exponents are pair.
5.- 1/3x² + 10 = 7
1/3x² = 7 - 10
1/3x² = -3
x² = -3(3)
x² = -9
x = ±3i
Answer:
the answer is 12
