Answer:
1.7
Step-by-step explanation:

The answer to your question is Y=5
Answer:
- shortest: 3 ft
- other: 4 ft
Step-by-step explanation:
The right triangle with hypotenuse 5 that has legs that differ by 1 is the 3-4-5 right triangle. The legs are 3 ft and 4 ft.
__
<em>Alternate solution</em>
If you have never heard of a 3-4-5 right triangle, you can figure the leg lengths algebraically using the Pythagorean theorem. Let x represent the length of the "other" leg. Then the shortest is (x-1). The Pythagorean theorem tells you ...
5^2 = (x)^2 +(x -1)^2
25 = 2x^2 -2x +1
12 = x^2 -x = x(x -1)
Factors of 12 that differ by 1 are 3 and 4 or -3 and -4. We want x to be positive, so the value of interest is x=4
The "other" leg is 4 ft; the shortest leg is 3 ft.
Answer:
(2). -1
Step-by-step explanation:
The given parameter can be represented as:

Required
The end result
From the question, we understand that m is a natural number
This means that:
odd number
So:
--- i.e. -1 to the power of an odd number will give -1
<em>Hence; (2) is correct</em>
Answer:
When y=2/5
(-y)^2= 4/25 and -y^2 = 4/25
When y =-2/5
(--2/5)^2 = 4/25 and -y^2 =4/25
