Answer:
5x-y-6=
Step-by-step explanation:
(y-y1)=m(x-x1)
y-(-1) =5(x-1)
y+1=5x-5
5x-5-y-1=0
5x-y-6=0
Step-by-step explanation:
u get this diagram^
to find DBC
B+40+90=180
B=50°
to find BCD
CDB is 90° ( since perpendicular to AB)
so taking triangle BCD
90+50+c=180
c=40°
Answer:
x = 5.5 (rounded)
Step-by-step explanation:
Equation: 700 = 132.69x - 25.96
Add 25.96 to both sides: 700+25.96 = 132.69x -25.96 + 25.96
Simplify: 725.96 = 132.69x
Isolate x
Divided both sides by 132.69:
Simplify: x = 5.5 (rounded)
Answer:
Step-by-step explanation:
The speed of light is and its frequency is .
The speed of light is given as:
c = λ * f
where λ = wavelength of light
f = frequency of light
Therefore, the wavelength is given as:
λ = c / f
=> λ =
=> λ =
The wavelength of the light is
