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

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
