Answer:
you have $250 in market and bonds and $500 in stocks.
step-by-step explanation:
you split 1,000 into 4 quarter and take two of those quarters and there is what you invested in stocks and take one quarter for market and one quarter for bonds.
1 is wrong there are two numbers greater than 4 but less than or equal to 6.
the first one was correct
First subtract 2 revolutions from the - 840 :- (- (840-720) = -120
This gives sin -120 which is in the 3rd quadrant of the unit circle
sin -120 = - sin 60 = - sqrt3/2
Standard form for y+7=-2/5(x-10) is y=-7-2/5(x-10)
