Answer:
1.
Step by step explanation:
We are asked to find which of the given equation has our given coefficient values.
Since we know that in quadratic equations a is quadratic coefficient, b is linear coefficient and c is our constant term.
Let us see our given equations one by one.
1.
We can see that coefficient of quadratic equation in our given option are:
a (quadratic coefficient)=-2
b (linear coefficient)= 1
c (constant) =3
Therefore, 1st option is correct choice.
2.
We can see that coefficient of quadratic equation in our given option are:
a (quadratic coefficient)=2
b (linear coefficient)= 1
c (constant) =3
Therefore, 2nd option is incorrect.
3.
We can see that coefficient of quadratic equation in our given option are:
a (quadratic coefficient)=-2
b (linear coefficient)= 0
c (constant) =3
Therefore, 3rd option in incorrect as well.
4.
We can see that coefficient of quadratic equation in our given option are:
a (quadratic coefficient)=2
b (linear coefficient)= -1
c (constant) =3
Therefore, 4th option is incorrect too.

Computing the circumferences of the two circles, we get:
.
To calculate the ratio of two numbers, we can divide one by the other. You can look at this as "How many times does the denominator fit in the numerator?"
So the circumference of the complex impact crater is 2 times greater than the circumference of the simple impact crater.
