Find the multiplier for 21.6% decay

Answers

Answer:

5pts

Step-by-step explanation:

The required multiplier for 21.6% decay is 78.4%.

Given that,
To find the multiplier for 21.6% decay

What is percentages?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

What is simplification?

The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.

In the question, the multiplier for the rate of 21.6% decay is to be determined.
A multiplier of decay implies decay  = 1 - r

Since let the Decay multiplier be x
x = 1 - r
x = 1 - 0.216
x = 0.784
x = 78.4%

Thus, the required multiplier for 21.6% decay is 78.4%.

Let the number of weeks be x

Subtract 209 on both sides
38x = 1197
Divide 38 on both sides
x = 31.5 weeks

Answer:

A

Step-by-step explanation:

You need to find the slope in A.  y = x + (4x - 1) = 5x -1.   The slope is 5.

In B,  as x increases 1 unit, y increases 1 unit.  Therefore, the rate of change is 1/1 = 1

Conclusion:  In A the rate of change is 5 and in B the rate of change is 1.

Therefore, A has a greater rate of change

Start with that form:  y = mx + b.  Substitute 1/2 for m, 6 for x and 3 for y, for the purpose of finding the value of the y-intercept, b:

3 = (1/2)(6) + b.  Thus, b = 0 and the desired equation is  y = (1/2)x.
