What is the mapping rule for a 45 degree rotation?

sleet_krkn [62]

Step-by-step explanation:

Imagine a line segment on a coordinate plane that rotates around the origin like a clock hand. If it travels 45° (or any positive degree angle), it will travel in a counterclockwise direction. If it rotates -45° degrees (or any negative degree angle), it will travel in a clockwise direction.

The graph below plots a function f(x):

Karolina [17]

By definition we have that the average rate of change of the function is given by:
$AVR = \frac{f(x2) - f(x1)}{x2 - x1}
$
Substituting values we have:
$AVR = \frac{100 - 50}{2 - 0}$
Rewriting we have:
$AVR = \frac{50}{2}$
$AVR = 25$
Answer:
If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.

Use the Pythagorean theorem to find the length of the leg in the triangle shown below 12 15

Norma-Jean [14]

Answer:

9 = x (assuming 15 is the hypotenuse)

Step-by-step explanation:

15^2 = 12^2 + x^2

225 = 144 + x^2

subtract 144 from both sides

81 = x^2

square root both sides

9 = x
