Answer:
i means Imaginary unit.
i to the zero power is 1
i to the first power is itself
i to the second power is -1
i to the third power is -i
Then, i to the fourth power is 1, so it all repeats again.
Hello there!
a) Basically, you are adding the length of porch to the original length of the parlor.
Let's say that the newly added porch is x.
(50 + x)(32 + x)
1600 + 50x + 32x + x²
x² + 82x + 1600
b) Just make the polynomial x² + 82x + 1600 equal to 2320.
x² + 82x + 1600 = 2320
subtract 2320 on both sides to make the polynomial equal to 0.
x² + 82x - 720 = 0
factor this
(x - 8)(x + 90) = 0
(x - 8) =0 (x + 90) = 0
x = 8 x = - 90
(-90ft doesn't make sense. So don't mind about this.)
So the porch should be 8ft.
Hope this helped!
The answer is pi but to fifteen places
Answer:
The correct answer option is: No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
