Step-by-step explanation:
points (-7,5) and (5,-3)?
This would mean to subtract the y coordinates:
5 - (-3) = 8
Then subtract the x coordinates in the same order:
-7 - 5 = -12
Then divide the y result by the x result for the slope:
8/-12 is the slope.
In simplest form, this is equivalent to -2/3
Answer: 45° and speed of light in prism 2×10⁸m/s
Step-by-step explanation:
The minimum deviation of the equilateral glass prism will form 60° angle.
So angle of incidence = 3/4×60
= 3 ×15
= 45°
Minimum deviation = δmin
= 30
After finding the value of μ using prism law
μ = 1.41
Speed of light will be 2×10⁸m/s

Answer:
17/20
Step-by-step explanation:
3/4 + 4/5 - 7/10
1. Find the LCD (Least Common Denominator). The LCD is 20.
2. 20/4=5. 5*3=15. So, 3/4 becomes 15/20.
3. 20/5=4. 4*4=16. So, 4/5 becomes 16/20.
4. 20/10=2. 2*7=14. So, 7/10 becomes 14/20.
5. Your new equation is 15/20 + 16/20 - 14/20.
6. Solve from left to right.
7. 15/20 + 16/20= 31/20.
8. 31/20 - 14/20= 17/20.
