Lillian would have approximately $14,599 in her account after 3 years, to the nearest dollar.

To find out how much Lillian would have in her account after 3 years, we need to use the future value of a series formula, which is:

[tex]FV = P \frac{(1 + r)^nt - 1)}{r}[/tex]

where:
FV = future value of the series
P = monthly deposit ($430)
r = monthly interest rate (annual interest rate / 12)
n = number of times interest is compounded per year (12)
t = number of years (3)

First, we need to find the monthly interest rate by dividing the annual interest rate (4.5%) by 12:
[tex]r =\frac{0.045}{12} = 0.00375[/tex]

Now we can plug the values into the formula:
[tex]FV = 430 \frac{(1 + 0.00375)^{12x3}  - 1)}{0.00375}[/tex]

Calculating the future value:
[tex]FV = 430\frac{(1.127334 - 1) }{0.00375} = 430 \frac{0.127334}{ 0.00375} = 430 (33.955)[/tex]
[tex]FV =14,598.65[/tex]

So, Lillian would have approximately $14,599 in her account after 3 years, to the nearest dollar.

Answer:

1. x = 5

2. x = [tex]\sqrt 7 \approx[/tex] 2.65

Step-by-step explanation:

To solve these problems, we can use the diagram below, as well as Pythagoras's Theorem, which states:

[tex]\boxed{\mathrm{a^2 = b^2 + c^2}}[/tex],

where a is the hypotenuse (longest side) of a right-angled triangle, and b and c are the legs of the triangle.

1. x is the hypotenuse:

From the diagram below, we can see that, if x is the hypotenuse of the triangle, then 3 and four are the legs of the triangle. Therefore, using the above equation:

[tex]x^2 = 3^2 + 4^2[/tex]

⇒ [tex]x = \sqrt{3^2 + 4^2}[/tex]      [Taking the square root of both sides of the equation]

⇒ [tex]x = \sqrt{25}[/tex]

⇒ [tex]x = \bf 5[/tex]

2. x is one of the legs:

From the diagram below, we can see that when x is one of the legs, the hypotenuse is 4, and the other leg is 3.

The hypotenuse isn't 3 because the hypotenuse is the longest side in a right-angled triangle, and 4 is longer than 3.

Therefore,

[tex]4^2 = x^2 + 3^2[/tex]

⇒ [tex]x^2 = 4^2 - 3^2[/tex]             [Subtracting 3² from both sides]

⇒ [tex]x = \sqrt{4^2 - 3^2}[/tex]          [Taking the square root of both sides of the equation]

⇒ [tex]x = \sqrt{7}[/tex]

       [tex]\approx \bf 2.65[/tex]

Let's use the variables "a" for the cost of an apple, "b" for the cost of a banana, and "o" for the cost of an orange.

From the first transaction:

- 3a + 5b + 4o = 8.85

From the second transaction:

- 8a + b + 3o = 8.10

From the third transaction:

- 2a + 2b + 2o = 4.40

We can now solve for one variable and substitute into another equation until we have found all three. Let's solve for "a" in the third equation:

- 2a + 2b + 2o = 4.40

- 2a = 4.40 - 2b - 2o

- a = 2.20 - b - o

Now we can substitute "a" into the first equation:

- 3a + 5b + 4o = 8.85

- 3(2.20 - b - o) + 5b + 4o = 8.85

- 6.60 - 3b - 3o + 5b + 4o = 8.85

- 2b + o = 0.75  (Equation A)

Next, we can substitute "a" into the second equation:

- 8a + b + 3o = 8.10

- 8(2.20 - b - o) + b + 3o = 8.10

- 17.60 - 8b - 8o + b + 3o = 8.10

- -7b - 5o = -9.50  (Equation B)

Now we have two equations with two variables, so we can solve for one variable and substitute into the other equation. Let's solve for "o" in Equation A:

- 2b + o = 0.75

- o = 0.75 - 2b

Now we can substitute "o" into Equation B:

- -7b - 5o = -9.50

- -7b - 5(0.75 - 2b) = -9.50

- -7b - 3.75 + 10b = -9.50

- 3b = -5.75

- b = -1.92 (rounded to the nearest cent)

Finally, we can substitute "b" into Equation A to find "o":

- 2b + o = 0.75

- 2(-1.92) + o = 0.75

- o = 4.59 (rounded to the nearest cent)

We can now find "a" by substituting "b" and "o" into one of the original equations. Let's use the first equation:

- 3a + 5b + 4o = 8.85

- 3a + 5(-1.92) + 4(4.59) = 8.85

- 3a - 9.60 + 18.36 = 8.85

- 3a = -0.09

- a = -0.03 (rounded to the nearest cent)

Since the cost of a piece of fruit cannot be negative, we made a mistake somewhere in our calculations. It's possible that we made a mistake in rounding at some point. To be sure, let's check our answers by substituting the values we found back into the original equation.

2(-0.0737) + 2(-0.0528) + 2o = 4.40

-0.1474 - 0.1056 + 2o = 4.40

2o = 4.6529

o = 2.3264 (rounded to 4 decimal places)

Therefore, each apple costs approximately $0.0737, each banana costs approximately $0.0528, and each orange costs approximately $2.3264.

The age of the specimen with half-life 5760 years, to the nearest hundred years is 3184 years.

To find the age of the specimen, we can use the formula:

A = ([tex]A_{1}[/tex])[tex]2^{(-t/5760)}[/tex]

Where [tex]A_{1}[/tex] is the original amount of carbon-14 (120 milligrams), A is the current amount of carbon-14 (100 milligrams), t is the time elapsed since the organism died, and 5760 is the half-life of carbon-14.

Substituting the given values, we get:

100 = (120)[tex]2^{(-t/5760)}[/tex]

Taking the natural logarithm of both sides, we get:

ln(100) = ln(120) - t/5760 * ln(2)

Solving for t, we get:

t = -5760 * ln(100/120) / ln(2)

t ≈ 3183.7 years

Therefore, the age of the specimen is approximately 3184 years, rounded to the nearest hundred years.

It's worth noting that radiocarbon dating is only accurate up to a certain point, as the amount of carbon-14 in a specimen eventually becomes too low to measure accurately. The maximum age that can be reliably determined through radiocarbon dating is around 50,000 to 60,000 years. Beyond that, other methods such as dendrochronology (tree-ring dating) or uranium-thorium dating may be used.

The area of the union of two disks with radius 1 and centers one unit apart is (5/3)π + (√(3))/4.

To find the area of the union of the two disks, we can use calculus to integrate over the area of overlap. The area of the union of the two disks is equal to the sum of the areas of C₁ and C₂ minus the area of their overlap. Each disk has a surface area of π(1)² = π, and a distance of 1 between their centers. We can use the law of cosines here,

The law of cosines states that c² = a² + b² - 2ab cos(θ), where c is the distance between the centers of the disks (1), a and b are the radii of C₁ and C₂ (1), respectively. Simplifying, we have,

cos(θ) = (1 - 1² - 1²)/(-211)

= -1/2,  so,

θ = 120 degrees.

The area of the overlap is equal to the area of a sector of C₁ with angle 120 degrees minus the area of the triangle formed by the centers of the disks and the point of intersection of the disks. The area of the sector is (120/360)π(1)² = (1/3)π, and the area of the triangle is,

(1/2)(1)(1)(sin(120)) = (√(3))/4.

Therefore, the area of the overlap is (1/3)π - (√(3))/4. The area of the union of the two disks is,

π + π - [(1/3)π - (√(3))/4]

= (5/3)π + (√(3))/4.

Thus, the area of the union of the two disks is (5/3)π + (√(3))/4.

The angles on the north side of the intersection are complementary angles because complementary angles are two angles whose measures add up to 90 degrees. At the intersection of Madison Street and Peachtree Street, the north side of the intersection forms a right angle (90 degrees).

Any angle on the north side of the intersection must be complementary to the right angle, meaning its measure must be less than 90 degrees.

For example, if we consider the angle formed by Madison Street and the north side of the intersection, it is less than 90 degrees and therefore complementary to the right angle formed by the intersection. Similarly, if we consider the angle formed by Peachtree Street and the north side of the intersection, it is also less than 90 degrees and complementary to the right angle formed by the intersection.

To find the Lagrange Error Bound for the third-degree Taylor polynomial, we need to use the formula: |Rn(x)| ≤ (M / (n + 1)) * [tex]|x - a|^{(n+1)[/tex]

where M is an upper bound for [tex]|f^{(n+1)(x)}|[/tex]on the interval [a,x], and Rn(x) is the remainder or error term in the Taylor series.

For the given function f(x) = [tex]e^x[/tex], we have:

f'(x) = [tex]e^x[/tex]

f''(x) = [tex]e^x[/tex]

f'''(x) = [tex]e^x[/tex]

Since[tex]f^{(4)}(x) = e^x[/tex] is also [tex]e^x[/tex], the maximum value of |f^(4)(x)| on the interval [-0.25,0.25] is [tex]e^{0.25[/tex].

Thus, we can set [tex]M = e^{0.25[/tex] and a = 0. Then, using n = 3 (for the third-degree Taylor polynomial), we have:

The volume of the original candy bar box can be found by using the formula for the volume of a triangular prism, which is V = (1/2)bh times the height. Since the base of the triangular prism has sides of 1.5 inches, we can use this to calculate the base area, which is (1/2)(1.5)(1.5) = 1.125 square inches.

The height of the original box is 8 inches, so the volume can be calculated as V = (1.125)(8) = 9 cubic inches.

For the new candy bar box, the length of each side of the triangular base is doubled to 3 inches, while the length of the prism is halved to 4 inches. Using the same formula for the volume of a triangular prism, the base area is now (1/2)(3)(3) = 4.5 square inches. The height of the new box is 4 inches, so the volume can be calculated as V = (4.5)(4) = 18 cubic inches.

There are 109 terms in given series.

Here, we have,

According to the statement

we have given that the sum of series is AP series and

This is 19 20.5 22 23.5 ... 181

And the sum of series is 10,900

Now, we have to find the number of terms in the series.

Then we use the summation formula which is

S = n/2 (a + L)

Substitute the all given values in it like

L = 181

A = 19 and S= 10,900

then

10,900= n/2(19+181)

10,900= n/2(200)

After solve the equation for n

10,900= 100n

n = 10,900 / 100

n = 109

There are 109 terms in given series.

So, There are 109 terms in given series.

The equilibrium level of output in the economy can be calculated using the following formula:

Y = C + I + G + NX

Where:

Y = Equilibrium level of output

C = Consumption

I = Investment

G = Government spending

NX = Net exports

We can calculate consumption using the marginal propensity to consume (MPC) and autonomous spending (A):

C = MPC(Y - T) + A

Where:

T = Taxes (assumed to be 0 in this case)

Substituting in the given values:

C = 0.8(Y - 0) + 2000

C = 0.8Y + 2000

Substituting in the given values for investment, government spending, and net exports:

Y = 0.8Y + 2000 + 7500 + 10000 - 1000

Y = 0.8Y + 19500

Solving for Y:

0.2Y = 19500

Y = 97500

Therefore, the equilibrium level of output in the economy is $97,500.

If net exports increase by $1000, then the new value of net exports (NX) is 0.

Substituting the new value of NX into the formula:

Y = 0.8Y + 2000 + 7500 + 10000 - 0

Y = 0.8Y + 19500

Solving for Y:

0.2Y = 19500

Y = 97500

Therefore, the equilibrium level of output in the economy is still $97,500.

The multiplier is calculated as:

Multiplier = 1 / (1 - MPC)

Substituting in the value of MPC:

Multiplier = 1 / (1 - 0.8)

Multiplier = 5

Therefore, the multiplier in this case is 5.

The baker bought approximately 17.5 pounds of flour.

Let's use algebra to solve the problem. Let x be the number of pounds of flour that the baker bought. We know that the cost of the flour is $15.05 and the price per pound is $0.86. So we can set up the equation:

$15.05 = $0.86 x

To solve for x, we can divide both sides by $0.86:

x = $15.05 ÷ $0.86

x ≈ 17.5

Therefore, the baker bought approximately 17.5 pounds of flour.

Tina received $12.30 for recycling her cans last week.

To find how much money Tina got for her cans last week, we need to find the total number of cans she collected and then multiply that by 0.05 (since she gets 5 cents per can).

On Wednesday and Thursday, Tina collected 37 cans each day, for a total of 2 x 37 = 74 cans.

On Tuesday, Friday, Saturday, and Sunday, she collected 43 cans each day, for a total of 4 x 43 = 172 cans.

The total number of cans collected is 74 + 172 = 246 cans.

To find the total amount of money Tina received, we multiply 246 by 0.05, which gives us:

246 x 0.05 = $12.30

Therefore, Tina received $12.30 for recycling her cans last week.
