Answer:
6.31 1/6
Step-by-step explanation:
6. For this problem, we know that 2 angles are congruent: the right angles and the angles closest to the "mirror." We know that those angles are congruent for mirrors reflect light to where it is congruent on both sides. Since we have two congruent angles, we can use AA Similarity to solve for the height of the hill. We can set up the proportion 6/34 = 5.5/x. We can cross multiply, which results in 6x = 187, and if we bring over the 6 so that x = 187/6, or 31 1/6.
Answer:
it is proportional
Step-by-step explanation:
constant of proportionality= 4
equation: b=4c
<span>Formula for exponential decay is:
N = No * e^-kt
N = 1/2(45) = 22.5
No = 45
k = 0.1109
The solution to your problem is as follows:
Let's try to solve the half-life if it is 45 grams, after which, you will now have an idea on how to solve the problem.
22.5 = 45 * e^(-0.1109t)
1/2 = e^(-0.1109t)
ln(1/2) = -0.1109t
t = (ln(1/2))/(-0.1109) = 6.25 days
