Solve 0 = x2 - 10x + 30 by completing the square.
o a. x = 5 + i and x = 5 - i
o
b. x = 5 + iv5 and x = 5 - iv5
o
c. x= -6 - iv6 and x = -5 + iv6
o
d. x= -5 - iv5 and x = -5 + iv5

we need the options

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

the answer is $23.63
