Step-by-step explanation:
- Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions.
Answer:
Step-by-step explanation:
So let's think about what values you can take square root of...
anything but negative values!
So the first one is not correct because you can also take square root of 0,
squareroot of 0 is 0.
So because of this, C and D are both correct, E is correct because root x is an increasing function. B is incorrect because (0,0) is an intercept.
2.7 is 27/10 and 3.6 is 18/5
Answer:
Here, 
represents temperature and 
denotes rate of chirping per minute.
Step-by-step explanation:
Let represents temperature and denotes rate of chirping per minute.
At 
°F, a certain insect chirps at a rate of 
times per minute.
Take 
At 
°F, they chirp 
times per minute.
Take 
Slope intercept form:
The answer is -20.
The negative part shows the loss and 20 is the amount of money
