Please help me with these questions! Will mark brainlist!

For part one 30000 and the slope for part two is -2000 and for part three it is y=30000=2000x.

Step-by-step explanation:

If it starts at 30,000 then that is on the 0 on the x-axis.

While the plane is descending by 2000 so that is the slope but because it is descending and not rising it is -2000. If it was rising it would be 2000.

And for part three because it starts and 30000 and it goes down 2000 by the x-axis.

Hope this helps.

-2,000

30,000

Y = 30,000-2,000X

Step-by-step explanation:

It decscends - 2000 feet

it has a [asitive slope and that is 30,000

m∠a is 90°

m∠b is 40°

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
