I have my maths exam in 20 minutes any tips on how to calm my nerves Its a 2 hour exam :/

1 answer:

3 0

Answer: Try breathing in and out a few times and telling yourself that you will be fine. If this does not work, try chewing gum for a few minutes, the gum gives you something to take your mind off your nerves and also induces a focused headset. Also try to visualize yourself passing the exam with flying colors so you won't worry as much. I hope this helps and your exam goes well! Stay safe.

Answer:

$\$272,49$

Step-by-step explanation:

7. $\displaystyle /text{The answer makes sense because since the depreciation rate is 15%, we know that we need to use the "exponential decay" formula.}$

6. $\displaystyle /text{After a depreciation rate of 15% for the past 8 years, the stock is now worth approximately $272,49.}$

5. $\displaystyle 1000[0,85]^8 = 272,490525 ≈ \$272,49$

4. $\displaystyle 1000 = a \\ -15\% + 100\% = 1 - r; 85\% = 1 - r \\ 8\:years = time\:[t]$

3. $\displaystyle /text{We need to use the "Exponential Decay" formula} - f(t) = a[1 - r]^t, where a > 0$

2. $\displaystyle /text{How much is the stock worth after a depreciation rate of 15% per year?}$

1. $\displaystyle /text{initial amount: $1000, a depreciation rate of 15%, and a time period of 8 years}$

How do you factor n^3-2n^2 ?

antoniya [11.8K]

Factor out common numbers or variables when you can.

To make this the most simplified factor, factor out n², as it is the least factor both have.

n³/n² = n
-2n²/n² = -2

n - 2 is your new answer

hope this helps
