Connor invests $1,400 in a savings account that compounds annually at a 9% interest rate. Determine how much money Connor will have after 4 years. Round to the nearest cent
Connor will have $ 1975.4 if he invests $1,400 with a 9% interest rate that compounds annually for 4 years.
Compound interest is given by the formula:
A = P [tex](1 + \frac{r}{n})^{nt[/tex]
where A is the amount
P is the principal
r is the rate of interest
n is the frequency with the interest is compounded in a year
t is the time
P = $ 1,400
r = 9% or 0.09
t = 4 years
Since the interest is compounded annually the frequency of the compounding is 1.
n = 1
A = 1400 [tex](1 +\frac{0.09}{1})^{1*4[/tex]
= 1400 [tex](1.09)^4[/tex]
= 1400 * 1.411
= $ 1975.4

A table tennis ball has a radius of 0. 04m. Estimate how many table tennis balls you could fit into the coin building! [search up what it is—]
( Width: 20m | height: 110m )
- How did you calculate your estimate?
- Explain how accurate you think your prediction is?
( Show Work. )
Number of balls ≈ [tex]1.03 * 10^9[/tex]
To calculate how many table tennis balls can fit into the coin building, we need to first figure out the volume of the building and the volume of the table tennis ball.
Then, we can divide the volume of the building by the volume of the ball to get an estimate of the number of balls that can fit inside.
The volume of a table tennis ball can be calculated using the formula for the volume of a sphere, which is:
V = (4/3)πr³
where V is the volume, π is pi (approximately 3.14), and r is the radius of the ball. In this case, the radius is given as 0.04m, so we can plug that in and get:
V = (4/3) x 3.14 x 0.04³
[tex]V =2.14 * 10^{-5} m^3[/tex]
Next, we need to find the volume of the coin building. The building has a width of 20m and a height of 110m, but we don't know its depth.
Let's assume that the building is a rectangular prism with a depth of 10m. Then, we can calculate its volume using the formula:
V = l x w x h
where l is the length, w is the width, and h is the height. Plugging in the given values, we get:
V = 20 x 10 x 110
V = 22000 m³
Now, we can divide the volume of the building by the volume of the ball to get an estimate of how many balls can fit inside:
Number of balls ≈ [tex]V_building / V_ball[/tex]
Number of balls ≈ 22000 / 2.14 x [tex]10^-5[/tex]
Number of balls ≈ [tex]1.03 * 10^9[/tex]
So we can estimate that approximately 1.03 billion table tennis balls can fit into the coin building.
As for the accuracy of this prediction, it's important to keep in mind that we made some assumptions and estimations in our calculations.
For example, we assumed that the building is a rectangular prism with a depth of 10m, which may not be completely accurate.
Additionally, we rounded some of our values and used approximations for pi.
Therefore, our estimate should be considered as a rough approximation rather than an exact calculation. Nonetheless, it gives us an idea of the scale of the building and how many objects it can hold.

The total cost for one dozen donuts include the cost to make the donuts and the cost of the box. Create an expression to model the cost for one dozen donuts where t represents the total surface area of the box
create an expression to model the total cost for one dozen donuts where t represents the total surface area of the box in square feet.
help please :(
The cost for one donut is $0.32, so the cost for one dozen donuts is:
12 donuts x $0.32/donut = $3.84
The cost for the cardboard box is $0.18 per square foot of cardboard, and there are 144 square inches in 1 square foot, so the cost per square inch of cardboard is:
$0.18 / 144 sq in = $0.00125/sq in
If t represents the total surface area of the box in square inches, then the cost of the box is:
t x $0.00125/sq in
To convert square inches to square feet, we divide by 144:
t/144 square feet x $0.18/square foot = t x $0.00125/sq in
Thus, the expression to model the total cost for one dozen donuts where t represents the total surface area of the box in square feet is:
$3.84 + (t/144) x $0.18

To get the derivative of the function f(x) = (5x - 5)(√x + 3) - 1/2, we'll first need to use the product rule and then simplify the expression. The product rule states that if you have a function g(x)h(x), its derivative is g'(x)h(x) + g(x)h'(x).
Let g(x) = 5x - 5 and h(x) = √x + 3.
Step 1: the derivatives of g(x) and h(x).
g'(x) = 5 (derivative of 5x - 5)
h'(x) = 1/(2√x) (derivative of √x + 3)
Step 2: Apply the product rule.
f'(x) = g'(x)h(x) + g(x)h'(x)
f'(x) = 5(√x + 3) + (5x - 5)(1/(2√x))

The absolute maximum value of f(x) on the interval [-3, 2] is 1, which occurs at x = 0. The absolute minimum value of f(x) on the interval [-3, 2] is -49, which occurs at x = 2.
To find the absolute maximum and minimum values of the function f(x) = 1 - 5x² on the interval [-3, 2], we first find the critical points of f(x) and then evaluate f(x) at the critical points and endpoints of the interval.
The derivative of f(x) is:
f'(x) = -10x
Setting f'(x) = 0, we get:
-10x = 0
which has only one critical point at x = 0.
Now, we evaluate f(x) at the critical point and endpoints of the interval:
f(-3) = 1 - 5(-3)² = -44
f(0) = 1 - 5(0)² = 1
f(2) = 1 - 5(2)² = -49
Therefore, the absolute maximum value of f(x) on the interval [-3, 2] is 1, which occurs at x = 0. The absolute minimum value of f(x) on the interval [-3, 2] is -49, which occurs at x = 2.

Robert uses f(x)=1000(1. 0375)^x to calculate the interest he earns each year for his savings account. What is the annual rate as a percent?
The annual rate as a percent is approximately 4.86% per year.
To find the annual rate as a percent, we first need to understand the function that Robert is using. The function [tex]f(x) = 1000(1.0375)^x[/tex] represents the amount of money Robert earns each year based on his initial investment of $1000 and the interest rate of 3.75% (as represented by the value 1.0375, which is 1 + 0.0375).
To calculate the annual rate as a percent, we need to isolate the interest rate from the function. We can do this by using logarithms. Taking the logarithm of both sides of the equation, we get:
log(f(x)) = log(1000) + x*log(1.0375)
Now, we can solve for the interest rate (represented by the value of 1.0375) by dividing both sides of the equation by x and then taking the antilog of the result:
1.0375 = antilog[(log(f(x)) - log(1000))/x]
Using this formula, we can plug in any value for x (representing the number of years Robert has held his investment) and find the corresponding interest rate. For example, if Robert has held his investment for 5 years, we can calculate the interest rate as:
1.0375 = antilog[(log(f(5)) - log(1000))/5]
This gives us an interest rate of approximately 4.86% per year. So, to answer the original question, the annual rate as a percent is approximately 4.86%.

A. Kiran will be billed approximately $2,284.33 one year after the date of purchase if she does not make any payments.
B. In this case, the overall cost of the sofa would be approximately $2,284.08
How to solve the problemsTo find the initial value of the home when Zahir purchased it, we can use the compound interest formula:
Future Value = Initial Value * (1 + (interest rate))^years
Let Initial Value be P. We are given the Future Value as $548,900, the interest rate as 4.8%, and the number of years as 15.
548,900 = P * (1 + 0.048)^15
Now, we'll solve for P:
P = 548,900 / (1 + 0.048)^15
P ≈ 305,113.48
a. Future Value = Initial Value * (1 + (interest rate / number of periods))^(years * number of periods)
Initial Value = $1,791.99
Interest Rate = 27.93% (0.2793)
Number of periods = 12 (monthly)
Years = 1
Future Value = 1,791.99 * (1 + (0.2793 / 12))^(1 * 12)
Future Value ≈ 2284.33
Kiran will be billed approximately $2,284.33 one year after the date of purchase if she does not make any payments.
b. interest were compounded annually:
Future Value = Initial Value * (1 + interest rate)^years
Future Value = 1,791.99 * (1 + 0.2793)^1
Future Value ≈ 2284.08
In this case, the overall cost of the sofa would be approximately $2,284.08, which is slightly lower than if the interest were compounded monthly ($2,284.33).

Find the equation of a line that goes throught point -2,-5 and is parallel to y = x + 2
The equation of the line that goes through the point (-2, -5) and is parallel to y = x + 2 is y = x - 3.
To find the equation of a line that goes through the point (-2, -5) and is parallel to y = x + 2, we will follow these steps:
1. Identify the slope of the given line.
2. Use the slope and the given point to find the equation of the new line.
Step 1: Identify the slope of the given line.
The equation of the given line is y = x + 2. This is in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept. In this case, the slope (m) is 1, as it is the coefficient of x.
Step 2: Use the slope and the given point to find the equation of the new line.
Since the new line is parallel to the given line, it will have the same slope. Therefore, the slope of the new line is also 1.
Now, we will use the point-slope form of a linear equation, which is given by y - y1 = m(x - x1), where m is the slope, and (x1, y1) is the given point.
Plugging in the values, we have:
y - (-5) = 1(x - (-2))
y + 5 = 1(x + 2)
Now, let's rewrite the equation in slope-intercept form:
y + 5 = x + 2
y = x + 2 - 5
y = x - 3
So, the equation of the line that goes through the point (-2, -5) and is parallel to y = x + 2 is y = x - 3.

You are making a 3 foot by 3 foot coffee table with a glass top surrounded by a cherry border of uniform width. The cherry border is included in the 3 x 3 measurements. You have 5 square feet of cherry border. What should the width of the border be?
Answer:
Step-by-step explanation:
The total area of the coffee table (including the cherry border) is:
3 feet x 3 feet = 9 square feet
We know that the area of the cherry border is:
5 square feet
To find the width of the cherry border, we need to subtract the area of the glass top from the total area of the coffee table:
9 square feet - area of glass top = area of cherry border
The area of the glass top is:
(3 feet - 2x) x (3 feet - 2x)
where x is the width of the cherry border.
Since the glass top is square, we can set the two dimensions equal to each other:
(3 feet - 2x) = (3 feet - 2x)
Expanding the left-hand side, we get:
9 feet - 6x = 9 feet - 6x
Simplifying, we get:
0 = 0
This means that the width of the cherry border does not affect the area of the glass top. Therefore, we can set the area of the glass top equal to the total area of the coffee table minus the area of the cherry border:
(3 feet - 2x) x (3 feet - 2x) = 9 square feet - 5 square feet
Simplifying, we get:
(3 feet - 2x) x (3 feet - 2x) = 4 square feet
Expanding the left-hand side, we get:
9 feet^2 - 12 feet x + 4x^2 = 4 square feet
Subtracting 4 square feet from both sides, we get:
9 feet^2 - 12 feet x + 4x^2 - 4 square feet = 0
Simplifying, we get:
4x^2 - 12 feet x + 9 feet^2 - 4 square feet = 0
Using the quadratic formula, we get:
x = [12 feet ± sqrt((12 feet)^2 - 4(4)(9 feet^2 - 4 square feet))] / (2(4))
Simplifying, we get:
x = [12 feet ± sqrt(144 feet^2 - 4(4)(9 feet^2 - 4 square feet))] / 8
x = [12 feet ± sqrt(144 feet^2 - 144 feet^2 + 64 square feet)] / 8
x = [12 feet ±

the expression (23.90 - 2) - (60.80 – 2) represents that a bouquet of daisies is
$18.45 more than a bouquet of tulips.
b
the expression (60.80 - 2) - (23.90 + 2) represents that a bouquet of tulips is
$18.45 more than a bouquet of daisies.
с
the expression 23.90 - 60.80 represents that a bouquet of tulips is $36.90 more than a
bouquet of daisies.
d
the expression 60.80 - 23.90 represents that a bouquet of daises is $36.90 more than a
bouquet of tulips.
The latter expression gives a positive result of $36.90, which means that a bouquet of daisies is $36.90 more expensive than a bouquet of tulips.
The given table shows the prices for various amounts and kinds of bouquets sold by a florist. The prices depend on the number and type of flowers in the bouquet. The table shows prices for bouquets of 2 flowers with daisies, tulips, and roses.
The expression (23.90 - 2) - (60.80 – 2) represents that a bouquet of daisies is $18.45 more expensive than a bouquet of tulips. This is because the cost of a 2-flower bouquet of daisies is $23.90 and the cost of a 2-flower bouquet of tulips is $60.80, so the difference between them is $36.90.
However, we subtract 2 from each price to get the price of the actual flowers in the bouquet, which are the same for both daisies and tulips. Therefore, we get the difference of $18.45.
Similarly, the expression (60.80 - 2) - (23.90 + 2) represents that a bouquet of tulips is $18.45 more expensive than a bouquet of daisies. Here, we subtract the price of a 2-flower bouquet of daisies plus the cost of 2 flowers from the price of a 2-flower bouquet of tulips.
Again, the actual cost of flowers in both bouquets is the same, so we get the difference of $18.45.
The expressions 23.90 - 60.80 and 60.80 - 23.90 represent the price difference between bouquets of daisies and tulips, respectively. The former expression gives a negative result of $36.90, which means that a bouquet of tulips is $36.90 more expensive than a bouquet of daisies.
The latter expression gives a positive result of $36.90, which means that a bouquet of daisies is $36.90 more expensive than a bouquet of tulips.

I need all the help to figure this annoying thing out
Answer:
x = 30 , y = 54
Step-by-step explanation:
the figure is a trapezium
each lower base angle is supplementary to the upper base angle on the same side, then
4x + y + 6 = 180 ( subtract 6 from both sides )
4x + y = 174 ( subtract 4x from both sides )
y = 174 - 4x → (1)
and
2x + 12 + 2y = 180 → (2)
substitute y = 174 - 4x into (2)
2x + 12 + 2(174 - 4x) = 180
2x + 12 + 348 - 8x = 180
- 6x + 360 = 180 ( subtract 360 from both sides )
- 6x = - 180 ( divide both sides by - 6 )
x = 30
substitute x = 30 into (1)
y = 174 - 4(30) = 174 - 120 = 54
thus x = 30 and y = 54

Factor out the GCF.
6x²-3x - 18
Factor completely and show/explain each step.
Answer:
3(x - 2)(2x + 3)
Step-by-step explanation:
6x² - 3x - 18 ← factor out GCF of 3 from each term
= 3(2x² - x - 6) ← factor the quadratic
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 2 × - 6 = - 12 and sum = - 1
the factors are - 4 and + 3
use these factors to split the x- term
2x² - 4x + 3x - 6 ( factor the first/second and third/fourth terms )
= 2x(x - 2) + 3(x - 2) ← factor out (x - 2) from each term
= (x - 2)(2x + 3) ← in factored form
then
6x² - 3x - 18 = 3(x - 2)(2x + 3)
