Write and solve the appropriate exponential equation:
228 = 16(r)^4, where r is the change per hour in the number of bacteria:
228
------ = r^4 = 14.25.
16
Taking the fourth root of both sides, we get: r = 1.94 (answer)
Expressions can be represented as logarithms and exponents
Rogelio argument is correct
<h3>How to determine if Rogelio's claim is true</h3>
The logarithmic equation is given as:

Apply logarithm rule, to rewrite the logarithmic equation

Evaluate the individual logarithmic expressions

Evaluate the quotient (i.e. divide the expression)

The above equation shows that
is between 6 and 7
Hence, Rogelio argument is correct

Answer:
89
Step-by-step explanation:
we substitute -7 into our function for x so:
(-7)² - 4(-7) + 11
= 49 + 28 + 11
= 89
