What are the potential solution of in(x^2-25)=0

and .

Step-by-step explanation:

The given equation is

We need to find he potential solution of the given equation.

Potential solution of an equation are the solutions of that equation which are lie on its domain. So, first find the domain of given equation.

Since logarithmic function is defined for positive values, therefore

It means x<-5 or x>5. So domain of the equation is

Domain =

We know that ln(1) = 0. The given equation can be written as

On comparing both sides we get

Add 25 on both sides.

Taking square root on both sides.

Both and belongs to the domain.

Therefore, the potential solutions of the given equation are and .

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.
