Answer:
8i
Step-by-step explanation:
<em>When a quantity is raised to a fractional power, you need to root it to the power of the denominator. </em>
<em>For example, </em><em>(-64)^(1/2) = √(-64) </em>
<em>Since you are taking the root of a negative, you will need to put an </em><em>i</em><em> (imaginary) in your answer.</em>
Answer:
Step-by-step explanation:
Cylinder
Formula
V = pi * r^2 * h
r = 2
h = 5
pi = 3.14
V = 3.14 * 2^2 * 5
V = 62.8 cm^3
Cone
V = 1/3 * pi * r^2 * h
Same answer as the cylinder only take 1/3 of it.
V = 1/3 * 62.8
V = 20.933
I am not sure if the “+” was supposed to go there or if that was just a typo, so I do apologize if this is wrong... but if it doesn’t belong in the equation at all, 20 = 2X is a fairly simply multiplication problem. You are to divide both sides by the 2 and you should get X = 10, because 2 goes into 20, 10 times; and the 2 goes into 2 only once, therefore the 2 now gets cancelled out.
Answer: 20 divided by 2 = 2x divided by 2 is now 10 = X.
Really hope this helps you, have a good day :)
