Answer:
If the shape of end face has n sides
Then, in total, there are n+2 faces
Using that formula
Faces in 20-sided polygon = n+2 = 20+2 = 22

So you know the horizontal acceleration is zero
integrating this you can find the horizontal velocity as
<span><span>vh</span>=Vcos(α)</span>
V = initial velocity 1200 ft/sec
the angle is 45 so you have
<span><span>vh</span>=1200cos(45)</span>
if you integrate this equation with respect to time (t) you get the horizontal displacement equation.
the initial condtions for the horizontal displacement seem to bet at t = 0, x = 0
then when you get the equation, just substitute t = 2 and evaluate
The correct answer is 19x-y=-5

Answer:
<h3>-4≤y≤7</h3>
Step-by-step explanation:
Given the inequality expressions
4y - 7 ≤ 3y and 3y≤5y+8
For 4y - 7 ≤ 3y
Collect like terms
4y - 3y ≤ 7
y ≤ 7
For 3y≤5y+8
Collect like terms
3y - 5y ≤ 8
-2y ≤ 8
y ≥ 8/-2
y ≥ -4
Combining both solutions
-4≤y≤7
<em>Hence the range of values of y that satisfies both inequalities is -4≤y≤7</em>
