Answer:
The square root of 64 is 8
Step-by-step explanation:
Answer:
A=670
B=301,600
C=560
Step-by-step explanation:
A is K divided by the wavelength (m) 301,500 / 450
B is wavelength(m) multiplied by the Frequency (Thz) 520x580
C is K divided by the Frenquency (Thz) 302400 / 540
Answer:
It is the second triangle.
Step-by-step explanation:
This is because the area of the square is given as 25^2 as the perpendicular, 144^2 as the base, and the hypotenuse is 169^2.
Length of the perpendicular = 5^2 (Because 25^2 / 5^2)
Length of the base = 12^2
Length of the hypotenuse = 13^2
So, the Pythagoras theorem is,
=> 
=> 
This is true, because, 13*13 = 12*12 + 5*5
=> 169 = 144 + 25
=> 169 = 169

Answer:
-2
Step-by-step explanation:
We can find the slope of a line given two points from
m = (y2-y1)/(x2-x1)
= (-2-4)/(1--2)
= (-6)/(1+2)
=-6/3
=-2
