In a survey, 74 out of 88 tourists interviewed said they had visited at least one of these continents: Africa, Europe and South America . of these, 19 had visited only Europe and Africa, 30 Europe and south America, 26 South America and Africa. No one had visited only Africa. | 10 only Europe 7 only South America and x had visited all the three Continents. 1. Draw a Venn Diagram to illustrate the information 2.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

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.

yes   because as the functions are graphed they eventually will intersect unless otherwise
