How long would it take a car with a top speed of 203 mph to travel 12.42 miles up a slope of 6.4% accelerating at 0.091 g's (2.93 ft/s sq.)

319 seconds

Step-by-step explanation:

The distance 12.42 miles is equivalent to

12.42*5280=65577.6 ft

When slope is 6.4%,

Therefore,

Also

Making t the subject of the formula by solving quadratic equation

t=318.4791278210496

Therefore, time is 319 seconds

$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
