To determine how long to leave $7500 in the bank at 6% interest compounded semi-annually to reach $16200, use the compound interest formula. Solving for t, time in years, yields approximately 11.9 years for the investment to grow to the desired amount.

To calculate how long the person must leave their money in the bank for it to grow from $7500 to $16200 with an interest rate of 6% compounded semi-annually, we'll use the formula for compound interest:

A = P(1 + \frac{r}{n})^{nt}

Where:

We are given:

Our goal is to solve for t, the time in years. Plugging the known values into the formula:

$16200 = $7500(1 + \frac{0.06}{2})^{2t}

Divide both sides by $7500:

2.16 = (1 + \frac{0.06}{2})^{2t}

Now take the natural logarithm of both sides:

ln(2.16) = ln((1 + \frac{0.06}{2})^{2t})

Use properties of logarithms to bring down the exponent:

ln(2.16) = 2t \cdot ln(1 + \frac{0.06}{2})

Divide both sides by 2ln(1 + \frac{0.06}{2}) to solve for t:

t = \frac{ln(2.16)}{2 \cdot ln(1 + \frac{0.06}{2})}

t = \frac{ln(2.16)}{2 \cdot ln(1.03)}

Using a calculator, we find t ≈ 11.9 years. Therefore, the person must leave the money in the bank for approximately 11.9 years to reach $16200.

To the nearest tenth of a year, the person must leave the money in the bank for approximately 13 years.

To find the time required for the investment to reach $16200, we can use the formula for compound interest:

[tex]\[ A = P \left(1 + \frac{r}{n}\right)^{nt} \][/tex]

Where:

- ( A ) is the amount of money accumulated after ( t ) years.

- ( P ) is the principal amount (the initial investment).

- ( r ) is the annual interest rate (in decimal form).

- ( n ) is the number of times interest is compounded per year.

- ( t ) is the time the money is invested for (in years).

Given:

- ( P = 7500 )

- ( A = 16200 )

- ( r = 0.06 ) (6% interest, converted to decimal)

- Interest is compounded semi-annually, so ( n = 2 )

We need to solve for ( t ):

[tex]\[ 16200 = 7500 \left(1 + \frac{0.06}{2}\right)^{2t} \][/tex]

[tex]\[ \frac{16200}{7500} = \left(1 + 0.03\right)^{2t} \][/tex]

[tex]\[ 2.16 = \left(1.03\right)^{2t} \][/tex]

Take the natural logarithm of both sides:

[tex]\[ \ln(2.16) = \ln\left(\left(1.03\right)^{2t}\right) \][/tex]

[tex]\[ \ln(2.16) = 2t \cdot \ln(1.03) \][/tex]

Now, solve for [tex]\( t \)[/tex]:

[tex]\[ t = \frac{\ln(2.16)}{2 \cdot \ln(1.03)} \][/tex]

[tex]\[ t \approx \frac{0.7693}{2 \cdot 0.0296} \][/tex]

[tex]\[ t \approx \frac{0.7693}{0.0592} \][/tex]

[tex]\[ t \approx 13 \][/tex]

So, to the nearest tenth of a year, the person must leave the money in the bank for approximately 13 years.

The equation of the parabola with vertex (2, -4) and directrix y = -6 is y = 0.25(x - 2)² - 4.

The equation of a parabola in vertex form is y = a(x - h)² + k, where (h, k) is the vertex, and a is a constant that determines the shape and direction of the parabola. Given the vertex (2, -4) and the directrix y = -6, we can determine the value of a using the formula a = 1 / 4(c), where c is the distance from the vertex to the directrix. Since the vertex lies two units above the directrix, the constant c = 2; hence, a = 1 / 4(2) = 0.25 or 1/4.

Thus, the equation of the parabola is y = 0.25(x - 2)² - 4.

Answer:

( X -2 ) ^2 = 8(y +4)

Step-by-step explanation:

Answer:

First option: You start with $3 and save $1 each month.

In this case, the relationship is linear. So the corresponding equation is: y=x+3. Where 'x' represents the month. For example, the amount of money that you will have after 7 months is going to be: y = 7 + 3 = 10. (Ten dollars).

Second option: You save $3 the first month, and then each month the amount triples.

In this case, the relationship is exponential. If each month the amount triples, it means that the first month you have $3, the second month $9 and the third month $27. The equation that correctly models this situation is [tex]y=3^{x}[/tex]. For example, the amount of money that you will have after 7 months is going to be [tex]y=3^{7} = 2187[/tex] (2187 dollars)

Third option: Your total savings is 3 times the number of months multiplied by itself.

In this case, the relation is quadratic. So the equation that models this situation is: [tex]y=3x^{2}[/tex]. For example, the amount of money that you will have after 7 months is going to be [tex]y=3(7)^{2} = 147[/tex] (147 dollars)

Answer:

$8.80

Step-by-step explanation:

In order to find the new price, you need to add 60% of the original price (5.50) to the original price. You have two options:

1) multiply $5.50*0.6 to get 60% of the original price. You would get $3.30. Then add $3.30+$5.50, which equals $8.80. This way takes longer but shows you all the steps.

2) The shorter way is to simply multiply $5.50*1.6, which also equals $8.80. This works because the "1" automatically adds the 5.50 to 60% of the original price, this way you don't have to multiply then add.

If you don't understand how the second way works or your teacher taught you #1, just do it the first way.

Final answer:

To find the new price after a 60% markup, you need to calculate 60% of the original price and then add it to the original price.

Explanation:

To find the new price after a 60% markup, you need to calculate 60% of the original price and then add it to the original price.

Step 1: Calculate 60% of $5.50. 60% is equivalent to 0.60, so multiply 0.60 by $5.50 to get $3.30.

Step 2: Add $3.30 to $5.50 to find the new price. $3.30 + $5.50 = $8.80.

Therefore, the new price of the item after the 60% markup is $8.80.

 [tex]arc\ lenght=\pi[/tex]≈[tex]3.14[/tex]

Step-by-step explanation:

You need to use the formula for calculate the arc lenght:

[tex]arc\ length=2\pi r(\frac{C}{360})[/tex]

Where "C"  is the central angle of the arc in degrees and "r" is the radius.

You know that the measure of the radius of the circle is 4 inches and the central angle is 45 degrees, then you can substitute into the formula [tex]arc\ length=2\pi r(\frac{C}{360})[/tex].

Therefore, you get that  the measure of the arc length is:

[tex]arc\ length=2\pi r(\frac{C}{360})\\\\arc\ length=2\pi (4in)(\frac{45\°}{360})[/tex]

[tex]arc\ lenght=\pi[/tex]≈[tex]3.14[/tex]

Pretty sure its Quadratic

Step-by-step explanation:

Linear, needs to be in a straight line.

Quadratic, involving the second and no higher power of an unknown quantity or variable.

Exponential, (of an increase) becoming more and more rapid.

Check the picture below.

now, we know the base is a square, thus the length = width, namely L = w, so

[tex]\bf SA=2(Lw+Lh+wh)\implies \stackrel{\textit{since we know that L=w}}{380=2(ww+wh+wh)} \\\\\\ \cfrac{380}{2}=w^2+2wh\implies 190=w^2+2wh \implies 0=w^2+2wh-190 \\\\\\ 0=(w+19)(w-10)\implies w= \begin{cases} -19\\ \boxed{10} \end{cases}[/tex]

since the units must be positive, we can't use -19.

Final answer:

To find the largest width for the voting box, we need to consider its surface area. By setting up an equation and differentiating it with respect to the width, we can find the maximum width. The largest width for the box would be approximately 58.46 inches.

Explanation:

To find the largest width of the voting box, we need to consider its surface area. The surface area of a square-based box is given by 2lw + lh + wh, where l is the length, w is the width, and h is the height. We are given that the height is 4.5 inches, and we need to find the maximum width. The maximum surface area is 380 in2, so we can set up the equation as follows:

2lw + lh + wh = 380

Substituting the given height and rearranging the equation:

2lw + (4.5)(w) + (w)(w) = 380

Simplifying the equation:

2lw + 4.5w + w2 = 380

Since we are trying to find the maximum width, we can differentiate the equation with respect to w and set the derivative equal to zero:

d(2lw + 4.5w + w2)/dw = 0

2l + 4.5 + 2w = 0

Solving for w:

w = (380 - 4.5l)/2

Since the width should be the largest possible, we can substitute the maximum value of the length. Given that the box has a square base, the length and width are equal. Therefore, we substitute l = w:

w = (380 - 4.5w)/2

Simplifying the equation:

2w = 380 - 4.5w

6.5w = 380

w ~ 58.46 inches

Therefore, the largest width that the box could have is approximately 58.46 inches.

Answer:

[tex]x_1=4\\x_2=-3[/tex]

Step-by-step explanation:

Multiply both sides of the equation by -1:

[tex](-1)(-x^2+x+12)=0(-1)\\x^2-x-12=0[/tex]

Now, you can Factor the quadratic equation to solve it:

Choose two number that when you multiply them you get -12 and when you add them you get -1. These numbers are: -4 and 3

Therefore, you get:

[tex](x-4)(x+3)=0\\x_1=4\\x_2=-3[/tex]

For this case we have the following quadratic equation:

[tex]-x ^ 2 + x + 12 = 0[/tex]

We can solve it by:

[tex]x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}[/tex]

Where:

[tex]a = -1\\b = 1\\c = 12[/tex]

Substituting:

[tex]x = \frac {-1 \pm \sqrt {1 ^ 2-4 (-1) (12)}} {2 (-1)}\\x = \frac {-1 \pm \sqrt {1 + 48}} {- 2}\\x = \frac {-1 \pm \sqrt {49}} {- 2}\\x = \frac {-1 \pm \sqrt {49}} {- 2}\\x = \frac {-1 \pm7} {- 2}[/tex]

We have two roots:

[tex]x_ {1} = \frac {-1 + 7} {- 2} = \frac {6} {- 2} = - 3\\x_ {2} = \frac {-1-7} {- 2} = \frac {-8} {- 2} = 4[/tex]

[tex]y ^ 2-1 = x[/tex]

We add 1 to both sides of the equation:

[tex]y ^ 2 = x + 1[/tex]

We apply square root to eliminate the exponent:

[tex]y = \pm \sqrt {x + 1}[/tex]

Answer:

10 1/2

Step-by-step explanation:\

dont change the whole number part

0.5 is the same as 1/2

so 10 1/2

Final answer:

To convert 10.5 to a fraction, express it as 105/10 and simplify it to 21/2.

Explanation:

When converting the decimal 10.5 to a fraction, we can view the number 10.5 as having one decimal place.

To express the decimal as a fraction, we put the decimal over its place value, which in this case is 10 since there is one decimal place (0.5 is in the tenths place).

Therefore, 10.5 can be expressed as 105/10.

However, this fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 5.

Thus, the simplified fraction for 10.5 is 21/2.

Answer:

After 9 movies they will have paid the same amount

Step-by-step explanation:

We must write an equation for Duke's expenses and an equation to represent Tennessee's expenses.

For Duke expenses we have:

A fixed expense of $ 111.60 per year

A variable expense of $ 4.00 for each movie.

The equation that represents the expenses is a linear equation like the one shown below

[tex]C = 111.60 + 4.00x[/tex]

Where C represents the cost and x the number of movies.

For Tennessee expenses we have:

A variable expense of $ 16.40 for each film.

The equation that represents the expenses is a linear equation like the one shown below

[tex]C = 16.40x[/tex]

Where C represents the cost and x the number of movies.

To know after how many movies have paid the same amount, we equate both equations and solve the variable x

[tex]111.60 +4.00x=16.40x\\\\16.40x - 4x = 111.60\\\\12.40x =111.60\\\\x =\frac{111.60}{12.40}\\\\x =9[/tex]

After 9 movies they will have paid the same amount
