URGENT PLEASE HELP A projectile is launched at a height of h feet above the ground at an angle of theta with the horizontal. The initial velocity is v0 feet per second, and the path of the projectile is modeled by the parametric equations x=(v0 cos theta)t and y=h+(v0 sin theta)t-16t^2 Write the parametric equations to model the path of a projectile launched from ground level (h = 0) at the given values of theta and v0 Use your equations to answer the following questions. Theta=15 degrees, v0=70 feet per second

this is false ^.^ lol

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
