Use the definition of continuity and the properties of limit to show that the function f(x)=x sqrtx/ (x-6)^2 is continuous at x=36.

The function is continuous at x = 36.

Step-by-step explanation:

We need to follow the following steps:

The function is:

The function is continuous at point x=36 if:

Therefore:

The value of the function at x = 36 is:

The limit of the is the same at both sides of x=36, that is, the evaluation of the limit for values coming below x = 36, or 33, 34, 35.5, 35.9, 35.99999 is the same that the limit for values coming above x = 36, or 38, 37, 36.5, 36.1, 36.01, 36.001, 36.0001, etc.

For this case:

Since

And

Then, the function is continuous at x = 36.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
