Please help me! Quick! Samir draws triangle PQR in the coordinate plane as shown. Then he rotates triangle PQR 90 degrees counterclockwise around the origin to form triangle P'Q'R'. Samir Incorrectly says the coordinates of Q' are (5.-4) (5,-4). What is the correct answer? How might Samir have gotten his answer?

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

$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

b. b < 1 might be the correct answer

you can use a^2+ b^2=c^2
