Answer:
Answer:
835.29 Hz
Explanation:
When moving towards the source of sound, frequency will be given by
f*=f(vd+v)/v
Where f is the freqiency of the source, vd is the driving speed, v is the speed of sound in air, f* is the inkown frequency when moving forward.
Substituting 800 Hz for f, 340 m/s for v and 15 m/s for vd then
f*=800(15+340)/340=835.29411764704 Hz
Rounded off, the frequency is approximately 835.29 Hz

Step-by-step explanation:
The answer is:
6x < -17
But the less than sign has a line underneath.
Multiply the given numbers by the number given in the head column, for example 0.0943 x 10 would be 0.943. a trick is to move the decimal to the right the same number of zeros present in the factor. comment if you need further explanation :)
