Please help me find the distance between the points (5,4) and (1,-2) and express the answer in simplest radical form.
finlep [7]
The distance between two points can be calculated using the following formula:
distance = sqrt [ (x2-x1)^2 + (y2-y1)^2]

Now, we are given the two points (5,4) and (1,-2)
Substitute with the given points in the above equation to get the distance as follows:
distance = sqrt [(1-5)^2 + (-2-4)^2]
distance = sqrt [16+36] = sqrt[52]
distance = 2√13 = 7.2111 units

Help would be appreciated.

Frequency=(speed of sound)/(wavelength)
that means
wavelength =(speed of sound )/(frequency)
speed of sound=344 m/s

4.
frequency=587. 33 Hz
thus
wavelength=344/587.33
=0.586 m


5.
frequency=493.88 nHz
thus
wavelength=344/493.88
=0.69653 m

6. Frequency= 698.46 Hz
wavelength= 344/698.46
wavelength=0.4925 m

9. Frequency =783.99 Hz
wavelength=344/783.99
wavelength=0.439 m

Please help it’s due at12!!!
Goshia [24]

Answer:

$2.25 per ft² (I think)

Step-by-step explanation:

Subtract 4.9 from 6.4 to get 1.5

Multiply 6.4 by 1.5 and multiply 4.9 by 1.5

Then you get 9.6 and 7.35

Subtract 7.35 from 9.6 and get 2.25
