5. during the eruption of mount st. helens in 1980. debris was ejected at a speed of over 440 feet per second
(300 miles per hour). the elevation in feet above sea level of a rock ejected at an angle of 75° above
horizontal is given by the function y(1) --1612 +425t+8200 where t is the time in seconds after the
iption. the rock's horizontal distance in feet from the point of ejection is given by x(i) = 1131. if the rock
landed at an elevation of 6000 feet, what is the horizontal distance from the point of ejection to where it!
landed rounded to the nearest hundred feet?

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

answer: -1

step-by-step explanation:

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
