Answer:
The answer is 35.5 square units


Step-by-step explanation:

The shape represents a rectangle, a small triangle removed from it at the upper right corner and a bigger triangle is attached to it at the upper left corner.

We get this formula:
A(shape) = A(rectangle) - A(small triangle) + A(big triangle)
SO LET'S FIND EACH!

A(rectangle)= length x width
length= 8 units
width= 4 units
We get:
A(rectangle) =8x4= 32 square unit

A(small triangle)= (base x height)/2
base= 1 unit
height= 1 unit
We get:
A(small triangle) = (1x1)/2 = 1/2 = 0.5 square units

A(big triangle)= (base x height)/2
base= 2 units
height= 4units
We get:
A(big triangle)= (2x4)/2 = 8/2 = 4 square units

For the final result:
A(shape) = 32 - 0.5 + 4 = 35.5 square units

If for a particular one-to-one function f(2) = 13, what are the corresponding input and output
maks197457 [2]

Answer:

f^{-1}(13) = 2.

Step-by-step explanation:

For function f, the notation f(2) = 13 means that when the input to the function is 2, the output would be 13.

The inverse function of a one-to-one function f is commonly denoted as \!f^{-1}.

The inverse function undoes the action of the original function. In this question, f maps 2 to 13. Thus, f^{-1} would need to map 13\! back to 2\!. Therefore, f^{-1}(13) = 2 should be the corresponding input and output values.
