Rear Windshield Wiper (Giving brainliest to correct answer)
Find Arc lengths and areas of sectors of circles

56.0% not wiped

Step-by-step explanation:

150° = 5π/6 rad

Area wiper covers

Aw = ½(5π/6)24² - ½(5π/6)2² = 238⅓π in² ≈ 748.75 in²

Area of window

(66 - 54)/2 = 6in

h = √(29² - 6²) = 28.37 in

A = 28.37(54 + 6) = 1,702.35

percentage not cleared by wiper is

(1,702.35 - 748.75) / 1,702.35 = 0.56016 ≈ 56.0%

Arc length ACB = rθ = 24(5π/6) = 20π ≈ 62.8 inches

inner arc length = 2(5π/6) = 5π/3 ≈ 5.23 inches

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
