Dilate the triangle with a scale factor of 2 and a center of dilation at the origin
satela [25.4K]

Answer:

To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2. I plotted all the new points to find the new triangle. To dilate the figure by a factor of 2, I will multiply the x and y-value of each point by 2.

The picture below shows a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image.

Step-by-step explanation:

ur welcome

Find a formula for the inverse of the function f(x)=3x^3 + 2sinx + 4cosx
vitfil [10]
Explicit Functiony = f(x) is said to define y explicitly as a function of x because the variable y appears alone on one side of the equation and does not appear at all on the other side.

Assign letters to all quantities that vary with time and any others that seem relevant to the problem. Give a definition for each letter.

2. Identify the rates of change that are known and the rate of change that is to be found. Interpret each rate as a derivative.

3. Find an equation that relates the variables whose rates of change were identified in Step 2. To do this, it will often be helpful to draw an appropriately labeled figure that illustrates the relationship.

4. Differentiate both sides of the equation obtained in Step 3 with respect to time to produce a relationship between the known rates of change and the unknown rate of change.

5. After completing Step 4, substitute all known values for the rates of change and the variables, and then solve for the unknown rate of change.</span>Local Linear Approximation formula<span>f(x) ≈ f(x₀) + f'(x₀)(x - x₀)

The function f(x) = StartRoot negative x EndRoot is represented by the graph. Which statement is correct?
Svetlanka [38]

Answer:

D. The range of the function is all real numbers greater than or equal to 0.

Step-by-step explanation:

The graph of the function y=\sqrt{-x} is shown in attached diagram.

1. The domain of the function is the set of all possible values for input (for x). Hence, the domain of this function is

x\in (-\infty,0]

2. The range of the function is the set of all possible values for output (for y), so the range of this function is

y\in [0,\infty)

As you can see, only option D is true - The range of the function is all real numbers greater than or equal to 0.
