What goes on top? for the 16 and 17 ?

Each of the numbers in the Pyramid can be found by adding the two numbers in the layer below it. Looking at the second layer, 7 = 3 + 4, 9 = 4 + 5, and 8 = 5 + 3, and in the third layer, 16 = 7 + 9 and 17 = 9 + 8. The top brick should then be the sum of the two below it, or 16 + 17 = 33.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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.
