none of those are equivalent to 0.04
Answer:
39 - 80i
Step-by-step explanation:
(8 - 5i)²
= (8 - 5i)(8 - 5i) (expand using FOIL. See attached for reference)
= (8)(8) + (8)(-5i) + (-5i)(8) + (-5i)(-5i)
= 64 - 40i - 40i + 25i²
= 64 - 80i + 25i² (recall that i² = -1)
= 64 - 80i + 25(-1)
= 64 - 80i - 25
= 39 - 80i
Answer:
vertex form f(x) = (x - 4)^2 - 4
Step-by-step explanation:
f(x)=x^2-8x+12 in vertex form
look at -8x
take -8 divide it by 2 and square result get 16
f(x) = x^2 - 8x + 16 - 16 + 12
f(x) = (x - 4)^2 - 16 + 12
f(x) = (x - 4)^2 - 4
vertex form f(x) = (x - 4)^2 - 4
Answer:
all of the above
Step-by-step explanation:
The point of portrait orientation is to make it so the picture focuses on the person. In order to do this you need to minimize the background, place attention on the foreground, and show more context
Answer:
2x^4 + x^3 - 2x -1
Step-by-step explanation:
Do each one at a time and add them after you are done is necessary, first multiply 2x times x^3 this gives 2x^4. Then multiply 1 times x^3 to get x^3. Then multiply 2x times -1 to get -2x. Then multiply -1 and +1 to get -1. Then combine them together. None of the terms are like terms so you don't need to worry about combining them further but keep that in mind for other problems. The final answer becomes 2x^4 + X^3 - 2x -1 because none of the terms are the same power.
