Can someone me answer this?
given the function f(x)= x^2+7x+10 / x^2+9x+20
describe where the function has a hole and how you found your answer.

we need to simplify the function by factoring the numerator and the denominator. plug the excluded values into the simplified function to find the hole.

The function f(x) has a hole at point x = - 5.

Step-by-step explanation:

We are given a function as

Now, we have to describe where the function has a hole.

Now,

⇒

Therefore, the common factor of the numerator and denominator is (x + 5).

Now, (x + 5) = 0

⇒ x = - 5

Therefore, the function f(x) has a hole at point x = - 5. (Answer)

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
