Answer: 54.88 mph
Step-by-step explanation: the Doppler effect formulae is given below as
f' = (v + vo) /(v - vs) × f
Where f' = observed frequency = 236 Hz,
f = frequency of sound source (stationary frequency) = 253 Hz.
v = speed of sound in air = 761 mph
Since the car (source) is moving away relative to the observer, vs will have a negative value (-vs)
vo = 0 mph ( since the observer is not moving)
By substituting the parameters, we have that
236 = (761+0)/(761 - (-vs)) × 253
236 = (761/ 761 +vs) × 253
By cross multiplication, we have that
236 × (761 +vs) = 761 ×253
761 + vs = 761 ×253/ 236
761 + vs = 192533/ 236
761 + vs = 815.88
vs = 815.88 - 761
vs = 54.88 mph

Step-by-step explanation:
The left side 0 does not equal to the right side
1.15470053
, which means that the given statement is false.
False
The average rate of change of function is 72.
<u>SOLUTION:
</u>
Given that, we have to find the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4
Use the slope formula to find the average rate of change:
To simplify this, we need to find values of f ( 4 ) and f ( 2 ) :
