Answer:
Number of hours= 13.61 hours
Step-by-step explanation:
Giving the following information:
Mr. Halloway knows that it is about 885 miles to their destination.
Average speed= 65 miles per hour
<u>To calculate the number of hours to be drive, we need to use the following formula:</u>
Number of hours= total miles / miles per hour
Number of hours= 885/65
Number of hours= 13.61 hours
The correct answers are x≠2 and x≠(-2).
Domain restrictions are any points in the domain where the function will not have a value. This basically means that it's a point where x won't work in the function.
For the numerator, any value will work for x. We can have a value of 0 in the numerator, or a positive, negative, or decimal number.
However, the denominator cannot equal 0. This is because a fraction bar represents division, and we cannot divide by 0. The values that make the denominator 0 can be found by:
x²-4=0
Add 4 to both sides:
x²-4+4 = 0+4
x² = 4
Take the square root of both sides:
√x² = √4
x = 2 or x = -2.
So 3^X= 2 is an exponential equation. The inverse of an exponential in ln. so take ln of both sides to solve.
Another way is to change the exponential into a log equation
So that would be log with base 3 to the power of 2 equals x.
