Wilbur landed his plane. the plane's elevation relative to the ground (in meters) as a function of time (in seconds) is graphed.

(image attached below)

how long was each descent by 50 meters?

a) 250 seconds
b) 10 seconds
c) 50 seconds
d) 100 seconds

Let's find the slope of this line.

slope=change in y/change in x

slope=8500-8000/0-100=500/-100=-5

So that means the plane is falling 5 meters per second.

So, the place will fall 50 meters in 10 seconds.

B

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
