<u>Answer:</u>
A) There are two complex solutions.
<u>Step-by-step explanation:</u>
To know how many solutions a quadratic equation has, calculate the discriminant of the equation.
discriminant = b² - 4ac
where a = coefficient of x²
b = coefficient of x
c = constant of equation
if b² - 4ac > 0 , then equation has 2 real roots
if b² - 4ac = 0 , then equation has 1 real, repeated root
if b² - 4ac < 0 , then equation has 2 complex roots
In this case, discriminant = 9² - 4(-2)(-12)
= -15
As -15 < 0, equation has 2 complex roots.
Answer: 55 residues
Step-by-step explanation:
We are given that length of sheet= 193 Å
We need to find out the number of residues in this segment.
Now in an anti parallel β sheet, the repeat comes out after every 7Å.
In every repeat, there are 2 residues.
So, to find out the number of residues in segment, we multiply the number of segments with the residues in every segment.
Residues in segment=
Residues in segment= 55.14
Or 55 residues.
I can answer only 1st coz I have no idea about 2nd problem..
Here Hypotenuse is 5
a =x
b =4
c = 5
5 square =x square +4 square..
25 =x square+16
25 -16 =x square
9 =x square..
√9 = x
3 = x..
