You want to find R. From angle R, you know the side lengths for opposite and hypotenuse. According to SohCahToa, that is sine. Sin (x) = Opposite / Hypotenuse = 2.5 / 5 = 0.5
Sine(x)=.5. To get x by itself divide both by the inverse of sine.
Answer:
C
Step-by-step explanation:
For this case we have the following exponential equation:
y = A (b) ^ t
Where,
A: initial amount
b: decrease rate
t: time in hours
We then have to rewrite the equation for this problem:
y = 200 * (0.5) ^ ((1/16) * t)
For t = 29 hours we have:
y = 200 * (0.5) ^ ((1/16) * 29)
y = 56.93943174 mg
Answer:
It will remain 56.94 mg after 29 hours
2(x + 3) = 20
2x + 6 = 20
2x + 6 - 6 = 20 - 6
2x = 14
x = 7
