Using the rule (x+5, y+2) you would add 5 to the x value and 2 to the y value so the answer would be L' (7,5) M' (6,4) N' (9,6)
Time taken to reach a person located 5m from the source is 0.2s
<u>Explanation:</u>
Given:
Frequency, f = 10Hz
Wavelength, λ = 2.5m
Distance, d = 5m
Time, t = ?
We know:
velocity = f X λ
v = 10 X 2.5
v = 25 m/s
We know:
Distance = speed X time
On substituting the value we get:
5 = 25 X t
t = 0.2 seconds
Therefore, time taken to reach a person located 5m from the source is 0.2s
Here the answer. -3x^4 +19x^3-38x^2+25x-3
2.5 if youre rewriting in decimal form
Answer:
x = 3.25 m
Step-by-step explanation:
First, find the height of the triangle using sin31:
sin 31 = h/9 ---> h = 9sin31 = 4.64 m
Next, we can now solve for x using tan55:
tan 55 = h/x --> x = (4.64 m)/(tan 55) = 3.25 m
