Answer: ![y=\frac{1}{4}x-7](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B4%7Dx-7)
Step-by-step explanation:
The perpendicular slope of the line(m) =
:
- m = -4 ⇒
![-\frac{1}{m} =-\frac{1}{(-4)} =\frac{1}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7Bm%7D%20%3D-%5Cfrac%7B1%7D%7B%28-4%29%7D%20%3D%5Cfrac%7B1%7D%7B4%7D)
The function formula is y = mx + b, where the y-intercept(b) is found by substituting in the values of a point on the line ⇒ (4, -6):
![y=\frac{1}{4}x+b\\-6=\frac{1}{4}(4)+b\\-6=1+b\\b=-6-1=-7](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B4%7Dx%2Bb%5C%5C-6%3D%5Cfrac%7B1%7D%7B4%7D%284%29%2Bb%5C%5C-6%3D1%2Bb%5C%5Cb%3D-6-1%3D-7)
<u>So the perpendicular equation is </u>

5280 feet per 1 mile
40 times 5280=211200
211200 feet per hour
Answer:
79.2 kilometres per hour
Step-by-step explanation:
1 km = 1000 m
1 hr = 3600 sec. To convert km/hr into m/sec,
We multiply the speed which in this case is 22m/s
by 3.6 giving 79.2 kmh. Therefore 22m/s into kilometer is 79.2 kmh.
