Which value of K will make x^2-1/4x+k a perfect square trinomial?

Answers

For this case we have the following polynomial:
 x^2 - (1)/(4)x + k
 We suppose that we have a standard equation of the form:
 ax ^ 2 + bx + c
 To make a perfect square trinomial, we need to complete the square.
 Therefore, the value of c is:
 c = ((b)/(2))^2
 Using this definition for this case, we have:
 k = (((-1)/(4))/(2))^2
 k= ( (-1)/(8) )^2
 k = (1)/(64)
 Therefore, the perfect square trinomial is:
 x^2 - (1)/(4)x + (1)/(64)
 Answer:
 The value of k is:
 k = (1)/(64)
1/64, because (-1/4)/2 is -1/8, and -1/8  ^2 is 1/64

James works as a waiter.Bills where $23.59,$40.65,$30.50 And $15.68His total tips was $17.67. What percent tip did he recieve for serving these meals. Round to nearest percent.

Answers

The percentage of the tip is 16%. This is computed by summing up all the bills, 23.59 + 40.65 + 30.50 + 15.68, which is equal to $110.42. Then $17.67 will be divided by $110.42, which is equal to 0.16000. After than to get the percentage we have to divide the 0.1600 by 100, which is equal to 16%.
