Answer:
13.7 ft^2
Step-by-step explanation:
1. Find the radius of the semicircle by dividing the diameter by 2 to get 1.8
2. Find the area of the semicircle. Do this by substituting the equation to find the area of a semicircle with the numbers given and solving. 3.14(1.8^2)/2 = 5.0868
3. Find the area of the triangle. Do this by substituting the equation to find the area of a semicircle with the numbers given and solving. 1/2(3.6*4.8) = 8.64
4. Add both your numbers together to get 13.7268
5. Round to the nearest 10th to get 13.7 ft^2
Hi there! The answer is D.
The parent function is the simplest form of a function. We can distinguish a variety of parent functions like linear, exponential, square root, absolute, logarithmic, quadratic, cubic, rational or constant (trigonometric functions excluded).
Now we can have a look at the function.

The thing that is the most important in this function is the square root, because this mainly decides the way the function looks. Therefore, the parent function is the simplest form of a square root function, which is the following:

Therefore the answer is D.
