Answer:
12.11 gallons
Step-by-step explanation:
Ciara's car used gas on 160 mile road trip = gallons
= gallons
Ciara's car used gas on 1 mile road trip =
=
= gallons
Ciara expect to use on a 250 mile road trip =
=
=
≈ 12.11 gallons
Ciara should expect to use or 12.11 gallons of gas.
You can just put that value 5 in place of x and then evaluate the output.
The value of f(5) for the given function is given by:
Option C: -43
Use the definition of function to evaluate the function on a given point. Most of the time, in general cases, the function will be algebraic and you just need to replace the input variables with the value of the point you want to evaluate the function on.
Since it is given that
thus, replace x with 5 everywhere and evaluate the result as:
Remember that is 2 multiplied by
, and so as
And
We get,
The value of f(5) for the given function is given by:
Option C: -43

Answer:
Quadrupled
Step-by-step explanation:
Let us consider rectangle be a figure whose dimensions are .
Then, the area of the rectangle will be:
Now, If we double the dimensions of the rectangle that is , then the area of the rectangle will become:
Therefore, if we double the dimensions of the rectangle, the area becomes quadrupled.
Thus, If the dimensions of a figure are doubled, then the area of the figure is Quadrupled.
