You need to draw out the triangle and then use the rules of a right triangle with tangent because you have the opposite side and you are trying to find the adjacent side.

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is stu

sasho [114]

Answer:

Step-by-step explanation:

Account A: Decreasing at 8 % per year

Account B: Decreasing at 10.00 % per year

The amount f(x), in dollars, in account A after x years is represented by the function below:

f(x) = 10,125(1.83)x

Account B shows the greater percentage

change

Step-by-step explanation:

Part A: Percent change from exponential

formula

f(x) = 9628(0.92)*

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.

f(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)”, 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.

What is the inequality4x-13<11

Shalnov [3]

Ok! First add the 13 over to the other side, which makes 4x<24.
Then divide 24 by 4, which gives you x<6.

I kinda sorta understand this but not completely

Problems 1 - 8.
When you multiply the same number raised to exponents, add the exponents. When you divide the same number raised to exponents, subtract the exponents.

1. $7^{-5} \cdot 7^{3} = 7^{-5 + 3} = 7^{-2}$

3. $\dfrac{2^{7}}{2^{10}} = 2^{7 - 10} = 2^{-3}$
