Answer:
Remember that the slope of perpendicular lines are negative reciprocals of each other.Step-by-step explanation:y = 1 - 2x the slope is -2 the value of the x term.So the slope of the new line using point (- 1, 2) is 1/2.Now use y = mx + b where y = -1, x = 2, and m = 1/2 .y = mx + b-1 = 1/2(2) + b solve for "b", the y-intersect-1 = 1 + b-2 = bThe line that is perpendicular to y = 1 - 2x is y = 1/2x - 2

Answer:
The maximum height of the marshmallow is 49 feet.
Step-by-step explanation:
The vertex form of a parabola is
.... (1)
Where, (h,k) is vertex of the parabola is a is constant.
The given function is
..... (2)
Where, h is height of the marshmallow (in feet) and t is the time (in seconds) after he throws the marshmallow.
From equation (1) and (2), we get

The value of a is -16, which is less than 0. So, the given function is a downward parabola.
The vertex of a downward parabola is the point of maxima.
The value of h is 14 and the value of k is 49. So, the vertex of the parabola is (14,49). It means the maximum height of the marshmallow is 49 feet in 14 seconds.
Therefore the maximum height of the marshmallow is 49 feet.
