PLS HELP! TWO MATH QUESTIONS
2 answers:
There is a formula that relates the arc length of a circle of radius, r, to the central angle ,θ in radians. S = r(θ) where S is arc length, r is radius, and θ is the central angle.
So substituting into the formula for the first question we have: 5.4=6(θ) and solving for θ we get 0.9
Now for the second question substituting into the formula we have:
S = 6(
)
Solving this for S we find the arc length to be 9π

First, you want to identify the slopes and y-int.
Equation 1 = y = -2x + 2
Slope = -2
y-int. = 2 or (0,2)
Equationt 2 = y = 2x + 3
Slope = 2
Y-int. = 3 or (0,3)
To graph, first plot the y-intercepts. Then do the slopes.
Slope = -2
Down 2 over 1 (to the right)
Slope = 2
Up 2 over 1 (to the right)
Then just connect the dots in a line!
