Dafna11 [192]

Answer:

$400 and $1,000

Step-by-step explanation:

Let us assume the x be the amount invested in 7% account

And, 600 + x be the amount invested in 9% account

Now the equation is

7x% + 9%(600 + x) = $118

0.07x + 54 + 0.09x = $118

0.16x = $118 -$54

0.16x = $64

x = $400

And, the other one is = $400 + $600 = $1,000

Given that the sec A = 13/5 and A is in QIV, determine exact value for the sin A.
AysviL [449]

Answer:

The exact value of sin A is opp/hyp = -12/13

Step-by-step explanation:

If A is in Quadrant IV then the "opposite side" is negative and the "adjacent side" is positive.  Since sec A = hyp / adj = 13 / 5 and since opp^2 + adj^2 must add up to hyp^2,   Therefore y = √(hyp^2 - adj^2), or

y = -√(13^2 - 25) = -√144 = 12.

The exact value of sin A is opp/hyp = -12/13
