If you bought a stock last year for a price of $142, and it has gone down 7% since then, how much is the stock worth now, to the nearest cent?

$132.06

Step-by-step explanation:

First find what 1% of the initial value is. To do this move the decimal place to the left two places. Doing this we ind that 1% of $142 = $1.42

Next multiply this value by 7 in order to calculate the 7% change.

Doing this we get $1.42 X 7= $9.94

Finally subtract the $9.94 from the initial value of the stock. In this case you will subtract because the stock's value went down.

Doing this we find that $142-$9.94= $132.06

y -5 = (-1/4)(x + 8)

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
