Based on the polynomial remainder theorem, what is the value of the function when x = 4?
ipn [44]

Answer:

124

Step-by-step explanation:

When x=4, substitute 4 into the function to give f(4).

f(4) = (4)^4 - 2(4)^3 + 5(4)^2 -20(4) -4\\f(4) = 256 - 2(64) + 5(16) - 80 -4\\f(4) = 256 -128 + 80 - 80 -4\\f(4) = 128+80-80-4\\f(4) = 208-80-4\\f(4) = 128-4\\f(4) = 124

Write the expression in standard form. <br> 2/2-15i
nlexa [21]
Standard form is a+bi

so get rid of that deonmenator

\frac{2}{2-15i}
multiply it by\frac{2+15i}{2+15i}
result is
\frac{4+30i}{4+225} = \frac{4+30i}{229}= \frac{4}{229} + \frac{30i}{229}

answer is \frac{4}{229} + \frac{30i}{229}
