Vikram is studying the square pyramid below. 33 2 in
IG
1 28.4
34 2 in
To find the surface area of the pyramid, in square inches, Vikram wrote (33.2) (342)+4
+44(34 2)(284)
What error did
Vikram make?
He used the same expression for the area of all four lateral faces.
He used the wrong expression to represent the area of the base of the pyramid.
He used the wrong value as the height when he found the area of the lateral faces.
He used an expression for surface area that only finds the total area of three faces.
Mark this and retum

3/6   and 9/18

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.
