Cosine = adjacent / hypotenuse
cosine = 1 / square root (2)
87654210 is the largest number
It would cost $35 because 10.50 divided by 3 = 3.5x10=35
Answer:
see below
Step-by-step explanation:
In addition to the exponent rule ...
(a^b)^c = a^(bc)
it is helpful to know the first few powers of some small integers.
5^3 = 125
9^2 = 81
4^3 = 64
2^6 = 64
__
- 125^3 = (5^3)^3 = 5^(3·3) = 5^9
- 81^7 = (9^2)^7 = 9^(2·7) = 9^14
- (1/64)^3 = ((1/4)^3)^3 = (1/4)^(3·3) = (1/4)^9
- (1/64)^3 = ((1/2)^6)^3 = (1/2)^(6·3) = (1/2)^18
The answer is really 1 5/6 because 5/6 + 2/3=5/6 NOT 7/3 so of course she is wrong
