Step-by-step explanation:
Let 's complete our quadrilateral to a rectangle ; and subtract from it the area highlighted in red
Answer:
y = (3 × 10^8 m/s)/x
Step-by-step explanation:
Speed of a wave is given by the product of wavelength and frequency.
Thus; speed = frequency × wavelength
If x = wavelength and y = frequency then speed will be;
speed = yx
Thus to get wavelength, y;
y = speed/x , but speed is 3 × 10^8 m/s
Thus;
y = (3 × 10^8 m/s)/x
Basically, they're asking you to find the slope of the given line, as well as finding how far apart each points are from one another, horizontally and vertically.
Remember, horizontal goes this way (------) and vertical goes this way (I)
(I)
(I)
a) Horizontal distance : -2
Vertical distance : 3
b) Slope :
Remember, slope is rise over run.
So, rise = vertical distance, and run = horizontal distance.
So, our slope is : -3/2

Answer:
angle of depression = 2.1⁰
Step-by-step explanation:
1 mile = 5280 ft
Hence angle of depression = 90 - ∅
Where ∅ is angle of depression
Tan ∅ = (5 x 5280)/ 950
∅ = Tan₋¹ (27.789474) = 87.9⁰
Hence angle of depression = 90 - 87.9 = 2.1⁰
