1st let's calculate the time needed to reach the maximum distance

h(t) = - 1/2 gt² + v₀t + h₀
h(t) = - 1/2 (9.8).t² + 110.t + 2 ; h(t) = -4.9.t² +110.t + 2
The time needed to reach the maximum height is when the derivative
 of h(t) is equal to 0:
h'(t) = 2(-4.9).t + 110 → h'(t) = -9.8.t + 110 = 0 and t = 11.22 seconds
Now to find the maximum height reaches, replace t with 11.2 in the equation
h(t) = -4.9.t² +110.t + 2

Estimate the sum of 703 + 620
Natalija [7]
When you estimate, you round each number, the add.
We round them to 
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320

Answer:

(3, 0).

Step-by-step explanation:

dentifying the vertices of the feasible region. Graphing is often a good way to do it, or you can solve the equations pairwise to identify the x- and y-values that are at the limits of the region.

In the attached graph, the solution spaces of the last two constraints are shown in red and blue, and their overlap is shown in purple. Hence the vertices of the feasible region are the vertices of the purple area: (0, 0), (0, 1), (1.5, 1.5), and (3, 0).

The signs of the variables in the contraint function (+ for x, - for y) tell you that to maximize C, you want to make y as small as possible, while making x as large as possible at the same time.

Hence, The Answer is ( 3, 0)

Answer:

\frac{ {x}^{2} }{y(x - y)}  +  \frac{ {y}^{2} }{ - x(x - y)}

\frac{ {x}^{2} }{y(x - y)}  -  \frac{ {y}^{2} }{x(x - y)}

\frac{ {x}^{2}  \times x  -  {y}^{2}  \times y}{xy(x -y)}

\frac{(x - y)( {x}^{2}  + xy +  {y}^{2}) }{xy(x - y)}

\frac{ {x}^{2} + xy +  {y}^{2}  }{xy}
