Answer:
Since 
, then we conclude that it will be a goal.
Step-by-step explanation:
Let the trajectory of the ball be represented by 
, where 
is the horizontal distance of the ball from origin, in feet, and 
is the height of the ball above ground, in feet.
If Deshawn does not block Chris's shot, then we should check if shot will be a goal and this condition must be fulfilled:
(1)
If we know that 
, then the height of the ball at the start of the goal is:
(2)
Since , then we conclude that it will be a goal.
Answer:
Step-by-step explanation:
Answer:
The minimum unit cost is 5377
Step-by-step explanation:
Note that we have a cudratic function of negative principal coefficient.
The minimum value reached by this function is found in its vertex.
For a quadratic function of the form
the x coordinate of the vertex is given by the following expression
In this case the function is:
So:
Then the x coordinate of the vertex is:
So the minimum unit cost is:
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
f(-3) would be 36.
When looking at synthetic division, the numbers across the top represent the coefficients of x^2, x and the constant in that order. Therefore, the equation is as follows.
2x^2 - 5x + 3
Now we can put -3 into the equation and solve.
2(-3)^2 - 5(-3) + 3
2(9) + 15 + 3
18 + 15 + 3
36
