Suppose you invested $4,500 and it grew by 4% every year for 30 years. How much would this investment be worth after 30 years?
Answers
Answer:
a) 14,595.29
Explanation:
We'll use the below compound interest formula to solve the given problem;
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]where A = future amount
P = initial amount = $4500
r = interest rate in decimal = 4/100 = 0.04
n = number of compounding periods = 1
t = time period = 30 years
Let's go ahead and substitute the above values into our formula and solve for A;
[tex]\begin{gathered} A=4500(1+\frac{0.04}{1})^{1\times30} \\ A=4500(3.24339751003) \\ A=14,595.29 \end{gathered}[/tex]We can see from the above that the investment would be worth $14,595.29 after 30 years.

Please help, due in 3 minutes Skylar still owes $550 oh her cresit card from the previous month. Her annual interest rate is 18%. Approximately how much should the interest charges Be when she gets the bill
Answers
Answer:
$8.25
Explanation:
If she gets the bill each month, we need to calculate the monthly interest rate as follows
18%/12 = 1.5%
Because 18% is the annual rate and a year has 12 months.
Then, the interest charge will be 1.5% of the amount, so
$550 x 1.5% = $550 x 1.5 / 100 = $8.25
Therefore, the interest will be $8.25

Answers
The values of x for which g(x) = 23 are x = 2.53 and x = -0.53
Determining the values of x for which g(x) = 23From the question, we are to determine the value(s) for which g(x) = 23
From the given information,
The function is
g(x) = 9x² - 18x + 11
Now, we will substitute g(x) = 23
That is,
23 = 9x² - 18x + 11
Rearranging
9x² - 18x + 11 - 23 = 0
9x² - 18x - 12 = 0
Divide through by 3
3x² - 6x - 4 = 0
Now, solve the quadratic equation
3x² - 6x - 4 = 0
Using the general formula,
x = [-b±√(b²-4ac)]/2a
a = 3, b = -6, c = -4
x = [-(-6)±√((-6)²-4(3)(-4))]/2(3)
x = [6±√(36 + 48)]/6
x = [6±√(84)]/6
x = [6 ± 9.17]/6
x = [6 + 9.17]/6 OR x = [6 - 9.17]/6
x = 15.17/6 OR x = -3.17/6
x = 2.53 OR x = -0.53
Hence, the values of x are x = 2.53 and x = -0.53

Muhammed has money to invest in one of two accounts.Account 1 requires a $2,000 investment for 4 years. It earns 3% interest compounded monthly.Account 2 requires a $2,200 investment for 2 years. It earns 5% interest compounded daily.Which account will earn more interest for Muhammed, and how much?Select the answer that is completely correct.Account 2 earns $232.39 more than Account 1.Account 1 earns $23.30 more than Account 2.Account 1 earns $18.87 more than Account 2.Account 2 earns $176.70 more than Account 1
Answers
Given:
Account 1:
Principal, P = $2000
Time, t = 4 years
Rate, r = 3% = 0.03
number of times compounded, n = monthly = 12 months/year
Account 2:
Principal, P = $2200
Time, t = 2 years
Rate, r = 5% = 0.05
number of times compounded, n = daily = 365 days/year
Let's determine the account which will earn more interest.
Apply the compound interest formula:
[tex]I=(P(1+\frac{r}{n})^{nt})-P[/tex]Where:
P is the Principal
r is the interest rate
n is the number of times the ineterest is compounded per unit time'
t is the time in years
Now, let's find the interest earned in each account.
• ACCOUNT 1:
[tex]\begin{gathered} I=(2000(1+\frac{0.03}{12})^{12\times4})-2000 \\ \\ I=(2000(1+0.0025)^{48})-2000 \\ \\ I=(2000(1.0025)^{48})-2000 \\ \\ I=2254.66-2000 \\ \\ I=254.66 \end{gathered}[/tex]
The interest earned in account 1 is $254.66
• ACCOUNT 2:
[tex]\begin{gathered} I=(2200(1+\frac{0.05}{365})^{730})-2200 \\ \\ I=(2200(1+0.00013698)^{730})-2200 \\ \\ I=2431.36-2200 \\ \\ I=231.36 \end{gathered}[/tex]
The interest earned in account 2 is $231.36
We can see the interest earned in account 1 is greater than the interest earned in account 2.
To find the difference, we have:
$254.66 - $231.36 = $23.30
Therefore, Account 1 earns $23.30 more than Account 2.
ANSWER:
Account 1 earns $23.30 more than Account 2.

Answers
The equation of the polynomial equation in standard form is P(x) = x³ - 25x²+ 209x - 585
How to determine the polynomial expression in standard form?The given parameters are
Degree = 3
Zero = 9, 8 - i
There are complex numbers in the above zeros
This means that, the other zeros are
Zeros = 8 + i
The equation of the polynomial is then calculated as
P(x) = (x - zero)^multiplicity
So, we have
P(x) = (x - 9) * (x - (8 - i)) * (x - (8 + i))
This gives
P(x) = (x - 9) * (x - 8 + i) * (x - 8 - i)
Evaluate the products
P(x) = (x - 9) * (x² - 8x - ix -8x + 64 + 8i + ix - 8i + 1)
Evaluate the like terms
P(x) = (x - 9) * (x² - 16x + 65)
Express in standard form
P(x) = x³ - 16x² + 65x - 9x² + 144x - 585
Evaluate the like terms
P(x) = x³ - 25x²+ 209x - 585
Hence, the equation is P(x) = x³ - 25x²+ 209x - 585

vic sam and li volunteered at a food bank for 52 hours if sam worked 3 fewer hours then vic and 4 fewer then li how many hours did li work?
Answers
Answer:
Li worked for 19 hours.
Explanation:
Let's call x the number of hours that Vic worked, y the number of hours that Sam worked, and z the number of hours that Li worked.
They all work for 52 hours, so:
x + y + z = 52
Sam worked 3 fewer hours than Vic and 4 fewer than Li, so:
y = x - 3 or y + 3 = x
y = z - 4 or y + 4 = z
So, we can replace x and z on the first equation and solve for y as:
(y + 3) + y + (y + 4) = 52
y + 3 + y + y + 4 = 52
3y + 7 = 52
3y + 7 - 7 = 52 - 7
3y = 45
3y/3 = 45/3
y = 15
Then, replacing y by 15, we can calculate the value of x and z as:
x = y + 3
x = 15 + 3
x = 18
z = y + 4
z = 15 + 4
z = 19
Therefore, Li worked for 19 hours.

To find:
The solution of the given inequality -4x < 8.
Solution:
Given inequality is -4x < 8. Divide both sides by -4 to isolate x.
If we divide an inequality by a negative number, then the sign of inequality changes to its opposite. So, on dividing the inequality by -4,we get:

Event 1 affects event 2.
So, these are dependent events.
2. Similar to the first question, event 1 affects event 2. Because event 2 is depending on the first event.
So, these are dependent events.
3. According to the problem, event 1 does not affect event 2.
So, these are independent events.
4. According to the problem, she selects one trading card and then she returns the card back. After this, she selects the other card. So, event 1 does not affect event 2.
So, these are independent events.
5. Similarly to the fourth question, event 1 does not affect event 2 because of the dropped back of balls.
So, these are independent events.
