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.
Really hard, buy I'll try to solve. um,since WX and YZ are perpendicular, you have to multiply since its a 90° right angle. I hoped I helped :) can I be brainliest it will make my day :)
A short-cut to accurately evaluate the given expression above is using a scientific calculator where one can include integrals and evaluate using limits. In this case, using a calculator, the answer is equal to 0.2679. One can verify this by integrating truly letting 1-x^2 as u and use its du to be substituted in the numerator
C^2 = 9^2 + 6^2
c^2 = 81 + 36
c^2 = 117
c = √117
c = 10.82
The answer is C. 32 inches squared
How to Solve:
Multiply 12 by 6 and then divide it by 2
12 multiplied by 6 equals 72
72 divided by 2 equals 36 therefore the answer is 36 inches squared.
