Answer:
![m=(y-b)/x](https://tex.z-dn.net/?f=m%3D%28y-b%29%2Fx)
Step-by-step explanation:
we have
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Solve for m
That means -----> isolate the variable m
Subtract b both sides
![y-b=mx+b-b](https://tex.z-dn.net/?f=y-b%3Dmx%2Bb-b)
![y-b=mx](https://tex.z-dn.net/?f=y-b%3Dmx)
Divide by x both sides
![(y-b)/x=mx/x](https://tex.z-dn.net/?f=%28y-b%29%2Fx%3Dmx%2Fx)
![(y-b)/x=m](https://tex.z-dn.net/?f=%28y-b%29%2Fx%3Dm)
Rewrite
![m=(y-b)/x](https://tex.z-dn.net/?f=m%3D%28y-b%29%2Fx)
Answer:
15.36 feet
Step-by-step explanation:
We solve the above question using Trigonometric function of Tangent
Tan θ = Opposite /Adjacent
From the question
θ = 38°
Opposite = the height of the chair = 12 feet tall
Adjacent = the distance from the base of the lifeguard's chair to the swimmer = x
Hence:
tan 38° = 12/x
Cross Multiply
tan 38° × x = 12
x = 12/tan 38°
x = 15.359299586
x ≈ 15.36 feet
Hence, the distance from the base of the lifeguard's chair to the swimmer is 15.36 feet
There are 16 ounces in a pound.
To convert from ounces to lbs, divide by 16.
30/16= 1 r14
Final answer: C 1 pound 14 ounces
Answer:
He would have run 21 miles in 3 hours.
Step-by-step explanation:
Answer:
The Slope of a line formula is given by
m=y2 - y1/ x2 - x1
Now Form a triangle using the straight line(It'd be best if you choose known Points on the graph)
Picking points (1, 2) and (2, 5) connect these points and you'll have a small triangle.
x1 y1 x2 y2
Substituting into the formula
m=5-2/2-1
m=3.
