This appears to be about rules of exponents as much as anything. The applicable "definitions, identities, and properties" are
i^0 = 1 . . . . . as is true for any non-zero value to the zero power
i^1 = i . . . . . . as is true for any value to the first power
i^2 = -1 . . . . . from the definition of i
i^3 = -i . . . . . = (i^2)·(i^1) = -1·i = -i
i^n = i^(n mod 4) . . . . . where "n mod 4" is the remainder after division by 4
1. = -3^4·i^(3·2+0+2·4) = -81·i^14 =
812. = i^((3-5)·2+0 = i^-4 =
13. = -2^2·i^(4+2+2+(-1+1+5)·3+0) = -4·i^23 =
4i4. = i^(3+(2+3+4+0+2+5)·2) = i^35 =
-i
Answer:
1.61
Step-by-step explanation:
1 mile × (5280 ft / 1 mile) × (1 kilometer / 3280.84 ft) = 1.61 kilometers
Answer:
it would be the second option
Step-by-step explanation:
Answer:
1 is false
2 is false
3 is true
4 is false
5 - its a type of trapezoid and is a quadrilateral
6 - A parallelogram has two pairs of parallel sides, whereas as trapezoid only has one parallel side.
7 - Harriet is incorrect because not all quadrilaterals can be any four sided shape, so it doesn't have to be a trapezoid or a parrelelogram
8 is additive. We know this because its adding 1 dollar everytime
9 is 6 because 122/32=6
10 - A trapezoid has one pair of parallel sides and a parallelogram has two pairs of parallel sides. So a parallelogram is also a trapezoid.
11 is A
12 is D
Step-by-step explanation:
Have a great day!
