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

Please help I'm almost done the test and need this and one other question ​
PolarNik [594]

Answer:

z=68

Step-by-step explanation:

Use the formula 180\times(n-2) to find the sum of the angles in a polygon, given <em>n</em> sides. This formula tells us the angles of this pentagon must add to 540 (180\times(5-2)=540).

So, we can setup an equation:

70+2z+11+119+z+2z=540

Solve for z:

200+5z=540 Combine like terms

5z=340 Subtract 200

z=68 Divide by 5

Therefore, the value of z = 68.
