Answer: B
Step-by-step explanation: To solve you have to first multiply the number in front of the first pair of () by both numbers inside,then add that together. Then move on the the other pair of (). Multiply those together. Take the two numbers that you now have and add those to get the final answer.
A function f(x) has solutions if we can find a value to plug in that leads to 0. In other words, there are solutions to f(x) = 0. Another term for "solution" is "root" or "x intercept"
An exponential function may cross the x axis at one point only. Though there are plenty of cases when there are no solutions at all. For instance, in the case of f(x) = (2^x) + 10
The right hand side will never be equal to zero no matter what you plug in for x. The graph will never cross the axis.
To answer your question, yes it is possible to have an exponential equation to have no solutions.
I think it would be 12.207… use the Pythagorean theorem (a^2+b^2=c^2) so 10^2+7^2
100+49=149
Then take square root of 149 to undo the the squaring of c and it should be around 12.207 :)
There is 45.9 inches for the whole year so
Edit: Misread the diagram, the previous answer was wrong.
