Answer: The total length in kilometers is 38 km
Step-by-step explanation:
17 + 2 = 19 km is 1/2 of the total length, that is,
19 = (1/2)h
(1/2)h = 19 multiply both sides by 2
h = 2*19
h = 38 km
Use the formula 1/2(base1+base2)height. Substitute the values.

Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:

When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes

Rewrite as:

Divide both sides by 16t

Hence, it takes the rocket 25 seconds to hit the ground
