Answer:
x-8
Step-by-step explanation:
since we dont know how much gas is in the tank, lets make that X.
and since we subtract 8 gallons from how much is in the tank, we make that X-8

Answer:
27/4 or negative 3/4
Step-by-step explanation:
We separate equation by looking at x and y projection separately.
Let us look at the x projection first.
Motion starts with initial velocity

because there is no force acting along the x-axis we don't have any acceleration along the x-axis. Our equation would be:

Now our y equation will be a little bit more complicated. There is gravity working against our projectile and we also have to take into effect the hight from which the projectile is launched.
With all that in mind let us write the equation for y projection:

The term

represents gravity and as you can see it is negative, which means gravity is pulling our projectile down.
There is one more thing we can do. We can express initial velocity

in relation to circular motion used to launch the projectile.

Where r is the length of the letter used to launch the projectile, and

is angular velocity.
If we combine our x and y equations we can get the trajectory of our projectile.

This is the equation of a parabola. If you follow this link(https://www.desmos.com/calculator/vogcuygjhs) it will take to an interactive graph where you can see how trajectory looks like depending on some of the paramaters.
