Answer:
1. (x,y)→(y,-x)
2. (x,y)→(-y,x)
3. (x,y)→(-x,-y)
Step-by-step explanation:
1. Rotation 90° clockwise (or 270° counterclockwise) about the origin changes x into y and y into -x, so it has the rule
(x,y)→(y,-x)
2. Rotation 90° counterclockwise (or 270° clockwise) about the origin changes x into -y and y into x, so it has the rule
(x,y)→(-y,x)
3. Rotation 180° clockwise about the origin changes x into y and y into -x, so it has the rule
(x,y)→(-x,-y)
Here you can apply rotation by 90° clockwise twice, so
(x,y)→(-y,x)→(-x,-y)
Answer:
The approximate solution to the system is 
.
Step-by-step explanation:
To solve the system of equations 
you must:
The approximate solutions to the system of equations are:
Answer:
The correct answer is E. Neither the frequency nor the wavelength is affected. Explanation: The wave frequency does not affect the speed of that wave. An increase in frequency of a wave causes a decrease in wavelength while the wave speed remains the constant. The speed of the waves is significantly higher at higher tensions.

Answer:
<em>f(50) = 109.44943 feet</em>
Step-by-step explanation:
<u>Modeling</u>
The model of a situation where the skid distance f is measured against the car speed x can be expressed as:
Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:
f(50) = 109.44943 feet
A is the true statement because the variable g us counted as 1 so then we subtract 6 from 1 =5g
