Answer:
16%
Step-by-step explanation:
800 is 16% of 5000 so and it decreased by 800, so it decreased by 16%
To solve this formula, we can simply use the formula of half-life of a radioactive substance to calculate the decay rate.
The disintegration constant or decay rate is calculated as 0.385min^-1
<h3>Half-Life</h3>
The half-life of a radioactive substance is defined as the time taken for the initial mass of the substance to reach half it's starting mass.
The formula is given as
Let's substitute the value into the equation and solve through
The disintegration constant or decay rate is calculated as 0.385min^-1

Answer:
Step-by-step explanation:
To find slope you have to take y2-y1 over x2-x1
y2=your second y poiny
y1=first y point
x2=second x point
x1=first x point
Since it is minus a negative you get to change it to a plus sign, because they cancel each other out.
3 + 7
____
-4-0
10/-4
This isn't quite simplified, so you find a common factor for the numerator (top number) and the denominator (bottom number). You should note the number has to go into both numbers, not just one. The largest common factor would be 2 in this case.
10/2=5
-4/2=-2
Now your simplified answer would be 5/2
Find the total amount put aside for the five years: 1040<span> × 5 = 5200
find the yearly amount spent: 6 </span>× 60 = 360
multiply amount spent by 5: 360 × 5 = 1800
subtract: 5200 - 1800 = 3400
