Question 5. PROBLEM SOLVING. Denmark, Norway and Sweden are worried that the Chinese navy will
sail around the world and threaten them, so they deploy their warships in a combined defensive force.
A warship from Denmark displaces 33 thousand tons and carries 6 big guns, a warship from Norway is
somewhat larger, and a warship from Sweden is larger still. The exact numbers are on this table:
COUNTRY
THOUSANDS OF TONS
BIG NAVAL GUNS
Denmark
33
6
Norway
40
7
Sweden
45
8

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.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
