B is the correct answer because they all equal -0.6
Yes, I'm getting C also!
Since it's asking for the left-endpoint Riemann Sum, you will only be using the top left point as the height for each of your four boxes, making -1, -2.5, -1.5, and -0.5 your heights. The bases are all the same length of 2. You don't include f(8) because you're not using right-endpoints, and that would also add another 5th box that isn't included in the 0 to 8 range.

Answer:
19.0 cm
Step-by-step explanation:
The length of each arc is given by ...
s = rθ
where r is the radius of the arc, and θ is its central angle in radians.
The sum of the two arc lengths is ...
s1 +s2 = (8 -4.5)(50(π/180)) +(8)(50(π/180)) = (16 -4.5)(5π/18) ≈ 10.0356
The sum of the two straight sides is ...
2·4.5 = 9.000
So, the perimeter is ...
P = arc lengths + straight sides = 10.0356 cm + 9.0000 cm ≈ 19.0 cm
Answer:
Step-by-step explanation:
To find the inverse function for y = f(x), solve the equation ...
x = f(y)
x = 2y +1 . . . . . . . use the function definition
x-1 = 2y . . . . . . . . undo the addition of 1 (subtract 1)
(x -1)/2 = y . . . . . undo the multiplication by 2 (divide by 2)
The inverse function is ...
f⁻¹(x) = (x -1)/2
