Complete the following tasks for this equation: b/7.8 = -2.15. Give an estimate for the solution. Be sure to explain how you arrived at the estimate, either by showing an equation or in words. Solve the equation. Show or explain your work. Compared to your estimate, is your answer reasonable? Explain your answer in complete sentences.

b = -16.77

Step-by-step explanation:

We could get a quick estimate from b/8 = -2:  b is approximately -16.

For an exact answer, multiply both sides by 7.8:  b = -16.77

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.

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
