Using an exponential function, it is found that f(5.5) = 19.8.
<h3>What is an exponential function?</h3>
An exponential function is a function in which the growth rate is a percentage, modeled by:
In which:
f(3.5) = 25 means that:
f(8.5) = 14 means that:
Hence:
Hence, the function is given by:
Then, when x = 5.5:

Answer:10 is the area
Step-by-step explanation:
For this case we have the following equation:
We must find the solution.
We add similar terms from the right side of the equation:
We subtract 5 from both sides of the equation:
We subtract 7x on both sides of the equation:
Different signs are subtracted and the sign of the major is placed:
We multiply by -1 on both sides of the equation:
Thus, the solution of the equation is . -5 is not a solution to the equation.
Answer:
. -5 is not a solution to the equation
Answer:
Step-by-step explanation:

A and b are irrational because we can’t graph them on a number line. One is a square root and the either is a decimal which is combined with the square root. The second is rational because the square root of 225 is 15 which can be graphed on a number line. 2.5 can also be graphed on a number line. We multiply these and get 37.5 which is possible to graph. 20 is irrational since it is not a perfect square. Therefore, it is difficult to add a square root and a decimal.
