Which of the following could be points in the unit circle a. (6/7, srqt13/7) b. (5/13, 12/13) c. (4/3, 4/5) d. (1/3, 2/3)

recall that a Unit Circle is called that because its radius is just 1.

now, using the pythagorean theorem, c = √( a² + b²)  whatever the values for "a" and "b" in the (a,b) point, they must yield a value c = 1, a radius of 1.

a

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
