If sin theta = 2/3 and tan theta < 0 what is the value of cos theta?
a) (sqrt5)/2
b) -sqrt5
c) (sqrt5)/3
d) -(sqrt5)/3

d)

Step-by-step explanation:

If   and , then

is in quadrant 2.

Recall that;

We substitute the given sine ratio to obtain;

We are in the second quadrant, therefore

$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
