The minute hand of a clock is 6 inches long. How far does the tip of the minute hand move in 15 minutes? How far does it move in 25 minutes?

Step-by-step explanation:

angle subtended at center in 15 minutes=360÷60×15=90°=π/4

distance traveled by minute hand=2πr/4=πr/2=6π/2=3π inches≈9.42 inches

distance travelled by minute hand in 25 minutes=2πr×25/60=50πr/60=5/6πr

≈5/6 π×6=5π inches ≈15.71 inches

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
