Exponential:
It is called the exponential function of base a, to that whose generic form is f (x) = a ^ x, being a positive number other than 1.
Every exponential function of the form f (x) = a^x, complies with the followingProperties:
1. The function applied to the zero value is always equal to 1: f (0) = a ^ 0 = 1
2. The exponential function of 1 is always equal to the base: f (1) = a ^ 1 = a.
3. The exponential function of a sum of values is equal to the product of the application of said function on each value separately.
f (m + n) = a ^ (m + n) = a ^ m · a ^ n
= f (m) · f (n).
4. The exponential function of a subtraction is equal to the quotient of its application to the minuend divided by the application to the subtrahend:
f (p - q) = a ^ (p - q) = a ^ p / a ^ q
Logarithm:
In the loga (b), a is called the base of the logarithm and b is called an argument, with a and b positive.
Therefore, the definition of logarithm is:
loga b = n ---> a ^ n = b (a> 0, b> 0)
The car went about 35.34 miles per gallon.(How? Divide 7.3 into 257 and you got your answer.)
Do you want the answer for question 1!? It's already done! It says Given right there, that's an example answer :)
Answer:
r = 525
Step-by-step explanation:
Id d represents the distance = 2625 miles
t represents time= 5 hr
and r represents the rate = ?
Therefore 2625 = r * 5
divide both sides by 5
525 = r
Hope that helps
