Step-by-step explanation:
From Pythagorean theorem, one of the sides can be determined as x^2 + y^2 =8^2
or y = (8^2 - x^2)^(1/2)
we can write the perimeter P as
P = 2x + 2y ---> 20 = 2x + 2(8^2 - x^2)^(1/2)
Dividing by 2, we get
10 = x + (8^2 - x^2)^(1/2)
Move the x to the other side,
10 - x = (8^2 - x^2)^(1/2)
Take the square of both sides to get rid of the radical sign:
(10 - x)^2 = 8^2 - x^2
Move everything to the left and expand the quantity inside the parenthesis:
x^2 + (100 - 20x + x^2) - 64 = 0
2x^2 - 20x + 64 = 0
or
x^2 - 10x + 32 = 0
Now we can see that a = -10 and b = 32
The correct answer is option A
• In mathematics, comparison of numbers if the process that defines similar properties between two numbers and identifies that the number if smaller or greater than or equal to the other number.
• In maths there are three special symbols used in comparison of numbers. The basic symbols are
1. Greater than (>)
2. Less than (<)
3. Equals to (=)
According to the question
Option A :
4.13 = 4.130
As we know the value of 0 after all the numbers and after the decimal is insignificant,
So , 4.13 = 4.130
This is correct comparison.
Option B :
5.16<5.06
Bigger number can’t be less than the smaller number, comparison is wrong.
Option C :
6.28<6.08
Bigger number can’t be less than the smaller number, comparison is wrong.
Option D:
7.09>7.19
Smaller number can’t be greater than the bigger number, comparison is wrong.
Option A is correct
