Answer:
Account A: Decreasing at 8 % per year
Account B: Decreasing at 10.00 % per year
Account B shows the greater percentage change
Step-by-step explanation:
Part A: Percent change from exponential formula
f(x) = 9628(0.92)ˣ
The general formula for an exponential function is
y = ab^x, where
b = the base of the exponential function.
if b < 1, we have an exponential decay function.
ƒ(x) decreases as x increases.
Account A is decreasing each year.
We can rewrite the formula for an exponential decay function as:
y = a(1 – b)ˣ, where
1 – b = the decay factor
b = the percent change in decimal form
If we compare the two formulas, we find
0.92 = 1 - b
b = 1 - 0.92 = 0.08 = 8 %
The account is decreasing at an annual rate of 8 %.The account is decreasing at an annual rate of 10.00 %.
Account B recorded a greater percentage change in the amount of money over the previous year.
Answer:
w = 6.
Step-by-step explanation:
5w + 3 = 4w + 9
5w - 4w = 9 - 3
w = 6
Then, check your work!
5(6) + 3 = 4(6) + 9
30 + 3 = 24 + 9
33 = 33
So, w = 6 will be the correct answer.
Hope this helps!
Answer:
The percent error of the scale is 2,5%
Step-by-step explanation:
<h3>First Step</h3>
Calculate the difference (error) between the weight recorded and the actual weight in lbs.
difference = 164 - 160
difference = 4 lbs
<h3 /><h3>Second Step</h3>
Convert the difference into percentage by comparing the difference to the actual weight, then multiplied by 100%
percent of difference = ![\dfrac{\text{difference}}{\text{actual weight}} \times 100 \%](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7Bdifference%7D%7D%7B%5Ctext%7Bactual%20weight%7D%7D%20%5Ctimes%20100%20%5C%25)
percent of difference = ![\dfrac{4}{160} \times 100 \%](https://tex.z-dn.net/?f=%5Cdfrac%7B4%7D%7B160%7D%20%5Ctimes%20100%20%5C%25)
percent of difference = ![\dfrac{400}{160} \%](https://tex.z-dn.net/?f=%5Cdfrac%7B400%7D%7B160%7D%20%5C%25)
percent of difference = 2,5%
