Question 6 the growth of a population each year is given by the function f(x)=250,000(1.17)* at what percent is the population growing each year? a. 250,000% b. 1.17% c. 292,500% d. 17%

Option D. 17%

Step-by-step explanation:

we have

This is a exponential function of the form

where

a is the initial value

b is the base

In this problem

a=250,000 people

b=1.17

Remember that

b=1+r

so

1+r=1.17

r=1.17-1=0.17

Convert to percentage

0.17*100=17%

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

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.
