Answer:
$705.79.
Step-by-step explanation:
The formula is
Amount = P(1 + r/100) ^ t so
Amount = 500 (1 + 9/100)^4
= $705.79.
X = 1 , y = - 2
Hope this helped
To answer this, you need to know the general form of an absolute value function. the equation for this is f(x<span>) = </span>a|x<span> - </span>h<span>| + </span>k, and in this equation, the vertex is (h, k).
with that information, you can see that your vertex will be (-5, 7). you must take the negative for 5 because the general equation states that your h value is usually subtracted from x. to check your vertex, try plugging it into your general equation:
f(x) = a|x - (-5)| + 7
f(x) = a|x + 5| + 7 ... you see that this matches your given equation. this last part here was just to show why your 5 must be negative; your answer is bolded.
Answer:

Step-by-step explanation:
1. Combine like terms
2y-7y = -5y
-5y=5
2. Divide by -5 and the answer is 
X = arcsin (1/2) = 30 degrees
