Given:
The initial mass of an element is 800 grams.
Decay rate = 8.2% per day
Number of days = 15
To find:
The remaining element after 15 days.
Solution:
The exponential decay model is
Where, a is the initial value r is the rate of interest and t is time period.
Putting 
in the above formula, we get
Therefore, the mass of the remaining element is 221.7 grams.
Answer:-7
Step-by-step explanation:do absolute value first and then put the negative sign
The value of y based on the values given ib the equilateral triangle will be 4.
<h3>How to illustrate the triangle?</h3>
From the information given, MN is one of the sides of the equilateral triangle. Therefore, side MR will be:
= 1/2 × 8 = 4
In the above, it should be noted that MR was calculated since it's half of the value of MN which is 8.
Here, value of y based on the values given ib the equilateral triangle will be 4.

The correct answer to this question is 240
From the image i've seen, the RDC has an angle of 120. So the major arc DC (that passes A and B) has an angle of 240.
So this makes that the measure of the angle of DAC is 240 because of the angle formed by RDC which is 120.
