We know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
the answer 
the ratio x:y is 25:18

Answer:
The position P is:
 ft     <u><em> Remember that the position is a vector. Observe the attached image</em></u>
 ft     <u><em> Remember that the position is a vector. Observe the attached image</em></u>
Step-by-step explanation:
The equation that describes the height as a function of time of an object that moves in a parabolic trajectory with an initial velocity  is:
 is:

Where  is the initial height = 0 for this case
 is the initial height = 0 for this case
We know that the initial velocity is:
82 ft/sec at an angle of 58 ° with respect to the ground.
So:
 ft/sec
 ft/sec
 ft/sec
 ft/sec
Thus

The height after 2 sec is:


Then the equation that describes the horizontal position of the ball is

Where
 for this case
 for this case
 ft / sec
 ft / sec
 ft/sec
 ft/sec
So

After 2 seconds the horizontal distance reached by the ball is:

Finally the vector position P is:
 ft
 ft
 
        
             
        
        
        
Answer:

Step-by-step explanation:
If a real number  is a zero of polynomial function, then
 is a zero of polynomial function, then 

is the factor of this function.
If a complex number  is a xero of the polynomial function, then the complex number
 is a xero of the polynomial function, then the complex number  is also a zero of this function and
 is also a zero of this function and

are two factors of this function.
So, the function of least degree is

If the polynomial function must be with integer coefficients, then it has a form
