Assoli18 [71]3 years ago

Answer:

x = 5

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 13², so

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25 ( take the square root of both sides )

x = \sqrt{25} = 5

Which of the following transformations does not
svlad2 [7]

Answer:

(9x, 9y) dilation

Step-by-step explanation:

(9, 9y) is the answer because F is 180 degrees rotations, G is not real, H is translations, and J is dilations and dilations is multiplying which makes the transformation non congruent.

The function g(x) is the transformation of the function f(x). Decide how f(x) was transformed to make g(x).
yan [13]

Answer:

Correct option: A -> Horizontal or vertical reflection

Step-by-step explanation:

We can observe that the value of x in f(x) gives a value that is the same value we have in g(x) with the value -x.

That is, x = 1 in f(x) gives the same result as x = -1 in g(x)

So this means that these functions are a reflex of each other in relation to the y-axis, as the x values of one have the same result as (-x) values for the other one.

So the correct option is A: Horizontal or vertical reflection

(It is a horizontal reflection)

Find a formula for the inverse of the function f(x)=3x^3 + 2sinx + 4cosx

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.
