A pizzeria sells a round pizza with a diameter of 16 inches. Another pizzeria sells a large square pizza with a side length of 15 inches

Which has more crust along the outside edge of the pizza, the round pizza or the square pizza?

Square pizza

Step-by-step explanation:

d = Diameter of round pizza = 16 inches

a = Side length of square = 15 inches

More crust means the edge length of the pizza is greater. Edge length is given by the perimeter.

Circumference or perimeter of the round pizza

Perimeter of the square is

So, the square pizza has more crust compared to the round pizza.

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.
