Answer:
0
Step-by-step explanation:
f(0) = -2(0)²
= -2(0)
= 0
Here is the equation:

You need to find f(3). To do that, substitute all the x's with 3:

The first thing you need to do is multiply 4 by 3. Multiply:

Here is your new equation:

To get your answer, you need to add 12 and 1. Add:

That means:

The answer is
h = AB sin tetha,
tetha is <span>1 degree 10' = 1.1°, and AB = 3.5km
the vertical rise is h = 4.7</span>
When it is in motion the force is unbalanced. When it stops the forces are balanced.
Answer:

Step-by-step explanation:
The slope intercept form is
.
The "
" is the slope; which in this case is -3. So
.
The "
" is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.
This is why the answer is
.
