Answer:
$1790.99
Step-by-step explanation:
<u>Given</u>:
$1625 is invested at an annual rate of 1.95% compounded quarterly for 5 years
<u>Find</u>:
the ending balance
<u>Solution</u>:
The compound interest formula applies.
FV = P(1 +r/n)^(nt) . . . Principal P at rate r for t years, compounded n per year
FV = $1625(1 +0.0195/4)^(4·5) = $1625(1.004875^20) ≈ $1790.99
The account ending balance would be $1790.99.
The <em>exponential</em> function y = 290 · 0.31ˣ reports a decay as its <em>growth</em> rate is less than 1 and greater than 0. Its <em>percentage</em> rate of decrease is equal to 69 %.
<h3>How to determine the behavior of an exponential function</h3>
<em>Exponential</em> functions are <em>trascendental</em> functions, these are, functions that cannot be described <em>algebraically</em>. The <em>simplest</em> form of <em>exponential</em> functions is shown below:
y = a · bˣ (1)
Where:
- a - Initial value
- b - Growth rate
- x - Independent variable.
- y - Dependent variable.
Please notice that this kind of <em>exponential</em> function reports a <em>growth</em> for b > 1 and <em>decay</em> for b < 1 and b > 0. According to the statement we have the function y = 290 · 0.31ˣ, then we conclude that the exponential function given reports a <em>decay</em>.
The <em>percentage</em> rate of decrease is determined by the following formula:
100 × (1-0.31) = 100 × 0.69 = 69 %
The <em>percentage</em> rate of decrease related to the <em>exponential</em> function is 69 %.

Answer:
C. the subtraction property of equality
Step-by-step explanation:
12-x = 7x + 32
Step - 1: -x = 7x + 20
In that case, we just swap 12 from the left side to right side, and then we subtract 12 from 32 which is on the right side. Therefore, we do not multiply, divide or add anything. So, the option "C" is correct.
Step 2: -8x = 20
In that case, we again subtract 12 by interchanging the side. Moreover, we change the side of 7x to deduct it from -x.
Therefore, in both the cases, we use the subtract property of equality.
Answer:
11 stories apart
Step-by-step explanation:
We let the "ground" be considered at height = 0
Anything above, is POSITIVE direction
Anything below, is NEGATIVE direction
8 stories are ABOVE, so that would be considered
+8
3 stores are BELOW, so that would be considered
-3
THe difference in height between them is:
8 - (-3) = 8 + 3 = 11
So, that is 11 stories apart (top and bottom)
