Answer:
The equation is 
at a rate of -23%.
Step-by-step explanation:
Decay can be represented by the equation 
. We can find the rate at which it decays by using t=3 hours and A=3000. This means 
in this context.
After substituting, we divided by 6000 to each side to get 0.5 on the left. Now to solve for r, we will take the natural log of both sides and use log rules to isolate r.
We know 
so we were able to cancel it out and divide both sides by 3.
We solve with a calculator 
We change -0.23 into a percent by multiplying by 100 to get -23% as the rate.
The equation is
$4.05/1.8 oz= $2.25 per oz
Final answer: $2.25 per oz
F(x) = 4x - 6
f(6) = 4(6) - 6
y = 24 - 6
y = 18
Answer is
D. 18
Since we are asked to find DF, and we are given an angle and the side opposite to it, we can use the sine function to find DF.
let x be the length of side DF.
sin(32)= 17/x
x= 17 / sin(32)
x= 32.08
approximately 32.1
