Expand sqrt((1+x)/(1-x)) in ascending powers of x up to the term in x^3
simplify all coefficients by using x=1/10 obtain an estimate to 3dp for sqrt(11)

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
