Due to the doppler effect the correct rank of this effect is: B- toward the listener at 50 km/h then A- toward the listener at 30 km/h and then C- away from the listener at 20 km/h
Need more info for the rest of the problem.
4+5=9
That is all I can see
It’s the first one, seven (7)
Answer/Step-by-step explanation:
Recall the acronym for trigonometric ratios: SOHCAHTOA
SOH means sine of the reference angle = opp/hypotenuse
CAH means cosine of the reference angle = Adj/hyp
TOA means tangent of the reference angle = opp/adj
a. Reference angle = A
opp = 15
hypotenuse = 17
Therefore:
b. Reference angle = A
Adj = 8
hypotenuse = 17
Therefore:
c. Reference angle = A
Adj = 8
Opp = 15
Therefore:
d. Reference angle = B
Opp = 8
hypotenuse = 17
Therefore:
e. Reference angle = B
Adj = 15
hypotenuse = 17
Therefore:
d. Reference angle = B
Opp = 8
Adj = 15
Therefore:
Answer:
<h2>5x - y = 3</h2><h2>5x - y - 3 = 0</h2>
Step-by-step explanation:
y = 5x - 3 <em>it's a slope-intercept form</em>
<em />
y = 5x - 3 <em>subtract 5x from both sides</em>
-5x + y = -3 <em>change the signs</em>
5x - y = 3 <em>it's a standard form</em>
<em />
5x - y = 3 <em>subtract 3 from both sides</em>
5x - y - 3 = 0 <em>it's a general form</em>
