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

This is how to round 6.47 to the nearest tenth.
First note that 6.47 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 6
Fractional Part: 47
To round 6.47 to nearest tenth means to round the numbers so you only have one digit in the fractional part.
