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
<span>The volume of a rectangular prism is:</span>

Where
l=lenght,
w=width
h=height
So, as this prism has a length of 312 inches, a width of 5 inches, and a height of 112 inches, the volume is calculated as follows:

Answer: The mean number of checks written per day 
Standard deviation
Variance 
Step-by-step explanation:
Given : The total number of checks wrote by person in a year = 126
Assume that the year is not a leap year.
Then 1 year = 365 days
Let the random variable x represent the number of checks he wrote in one day.
Then , the mean number of checks wrote by person each days id=s given by :-

Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e. 
Standard deviation : 
The answer is
X^2+y^2+Dx+Ey+F=0
