Answer: D. No, a and b are interchangeable, and C is the longest side.
Step-by-step explanation:
Either A and B which are the two legs can be greater than the hypotenuse which is C. They hypotenuse has to always be greater than the two legs and the two legs have the same lengths but it can't be greater than the hypotenuse.
For example let's say you have a right angle with side lengths 3,4 and 5.
5 in this case has to be always the hypotenuse.
A could be either 3 or 4 but not 5
And B could also be 3 or 4 but not 5
because A squared plus B squared is always equal to the hypotenuse which is 5.
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25
There is a pattern. Each number is added by 5. So take 22 and add 5 to get 27. Just repeat until you find your answer, which would be 42.
Answer:
c. 1/128
Step-by-step explanation:
(2 ^ -5)^2
----------------------
2^ -3
Lets first simplify the numerator.
a^b^c = a^(b*c)
(2 ^ -5)^2 = 2^(-5*2) = 2^-10
(2 ^ -10)
----------------------
2^ -3
When dividing, since the bases are the same, we keep the bases and subtract the exponents.
a^b/ a^c = a^(b-c)
2^(-10- -3)
2^(-10+3)
2^(-7)
We know the negative exponent moves it from the numerator to the denominator
1/2^7
1/128
Answer:
y=-2x
Step-by-step explanation:
The shape of the cross section should be a square. If it were don’t vertically, the cross shape would be a triangle.
Hope this helps :)
