The formula for half-life is:

A is the amount remaining, P is the initial amount, t is the time that has passed, and h is the half-life of the substance. Plug in the values that you know and solve:

Rounded to the nearest whole number, the density of the substance was about 13<span>mg / cm².</span>
Given:
In ΔOPQ, m∠Q=90°, m∠O=26°, and QO = 4.9 feet.
To find:
The measure of side PQ.
Solution:
In ΔOPQ,
[Angle sum property]




According to Law of Sines, we get

Using the Law of Sines, we get


Substituting the given values, we get




Approximate the value to the nearest tenth of a foot.

Therefore, the length of PQ is 2.4 ft.

It is 0.0225 because p<span>ercentage means 'out of 100 100 '. Convert the </span>decimal<span> number to a fraction by shifting the </span>decimal<span> point in both the numerator and denominator. Since there are 2 2 numbers to the right of the </span>decimal<span> point, move the </span>decimal<span> point 2 2 places to the right.</span>
Answer:
First get y by itself. (y=-2/3x +2). The y-intercept is at 2 and the slope is -2/3 so starting at (0,2) you would go down two and right three and continue doing that to create your graph.
Step-by-step explanation:
Desmos is always a good option for checking your graphs :)
