Knob Hill Savings Bank offers a one-year CD at 3.88% interest compounded
daily.
What is the APY for this account? Round to the nearest hundredth of a
percent.
Answer:
3.95%
Step-by-step explanation:
The computation of the APY is shown below:
As we know that
A = P(1 + rate)^n
where,
A = full and Final amount (Principal + Interest )
r = rate of interest
n = time
Now
Let us assume that P = $100.
Now placing the values,
A = $100 × (1 + (3.88% ÷ 365)^365
= $100 × (1 + 0.000106301 )^365
= $100 × (1.000106301 )^365
= $100 × 1.039560407
= $103.9560407
Now the annual percentage yield is
= Amount - principal
= $103.9560407 - $100
= 3.95%

What is meant by a function?A function from a set X to a set Y allocates one element of Y to each element of X.
The earliest known attempt to the concept of function may be traced back to the works of Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. Functions were initially the idealization of how a variable quantity depended on another quantity. The position of a planet, for example, is a function of time. Historically, the notion was developed with the infinitesimal calculus at the end of the 17th century, and until the 19th century, the functions that were analyzed were differentiable.
Given,
2) f(x)=5x²-4, g(x)=1-x
gof=g(f(x))

The amount of fresh water left in the tanks of a nineteenth-century clipper ship is a linear function of the time since the ship left port, as shown in the table. Write an equation in point-slope form that represents the function. Then find the amount of water that will be left in the ship's tanks 60 days after leaving port.
1=3555
8=3240

The line with slope m that contains the point (x1, y1) can be described by the equation
y − y1 = m(x − x1). In a real-world linear situation, you may have information that represents two points on the line. You can write an equation in point-slope form that represents the situation and use that equation to solve a problem.
Let x represent the number of days since the ship left port and y represent the number of gallons of water.
Two points on the line are (8,3240) and (1, 3555).
m =
3555 − 3240
1 − 8
=
315
−7
= −45
y − y1 = m(x − x1) Point-slope form.
y − 3555 = −45(x − 1) or y − 3240 = −45(x − 8)
y − 3555 = −45(60 − 1) Substitute for x.
y − 3555 = −2655 Simplify the right side.
y = 900 Solve for y.
900 gallons of water will be left after 60 days.
Hope this helped! (I didn't do it sooner cause I just did the quiz lol)
The equation of the function, in point-slope form, is given by:
\(y - 3555 = -45(x - 1)\)
The amount of water left in the ship after 60 days is of 900 cubic units.
A line, in point-slope form, is represented by the following equation:
\(y - y_0 = m(x - x_0)\)
In which:
m is the slope, which is the rate of change.The point is \((x_0, y_0)\).We have two points: (1, 3555) and (8,3240).
Taking the first point, \(x_0 = 1, y = 3555\).The slope is given by change in y divided by change in x, thus:\(m = \frac{3240 - 3555}{8 - 1} = -45\)
Then
\(y - y_0 = m(x - x_0)\)
\(y - 3555 = -45(x - 1)\)
The amount after 60 days is y when x = 60, thus:
\(y - 3555 = -45(60 - 1)\)
\(y = 900\)
The amount of water left in the ship after 60 days is of 900 cubic units.

Am animal shelter provides a bowl with 1. 25 liters of water for 3 cats. About how much water will be left after the cats drink their average daily amount of water?
There will be approximately 0.05 liters of water left in the bowl after the cats drink their average daily amount of water.
To determine the amount of water left after the cats drink their average daily amount, we need to know the average daily water consumption per cat. Let's assume that each cat drinks 0.4 liters of water per day.
The total water consumption for the three cats would be 3 cats * 0.4 liters/cat = 1.2 liters.
Since the initial amount of water in the bowl is 1.25 liters, we can subtract the total water consumption from the initial amount to find the remaining water:
Remaining water = Initial amount - Total water consumption
Remaining water = 1.25 liters - 1.2 liters

A department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. What is the percent markup? A department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. What is the percent markup?
The percent markup of a department, if they sell 300 shirts at a cost of $9 each is 50%
According to the question, we learn that a department store buys 300 shirts at a cost of $1,800 and sells them for $9 each. This means :
The selling price of 300 shirts = 300 × $9
The selling price of 300 shirts = $2700
Selling price > cost price i.e., 2700 > 1800
when selling price is greater than cost price it means department store made a profit.
Profit = selling price - cost price
Profit = 2700 - 1800 = $900
Profit percentage = profit/ cost price × 100
Profit % =\(\frac{900}{1800} \times 100\)
Profit % = 50%

which equation can be used to determine the reference angle, r, if θ = 7π/12?
a. r = θ
b. r = π - θ
c. r = θ - π
d. r = 2π - θ
The equation that can be used to determine the reference angle, r, if θ = 7π/12 is option (b) r = π - θ.
A reference angle is the acute angle formed by the terminal side of an angle and the x-axis. To find the reference angle, we need to subtract the angle from either π/2 or π (depending on which quadrant the angle is in).
In this case, 7π/12 is in the second quadrant (between π/2 and π). Therefore, we subtract 7π/12 from π to get the reference angle:
r = π - θ
r = π - 7π/12
r = (12π/12) - (7π/12)
r = 5π/12
So the reference angle, r, for θ = 7π/12 is 5π/12.
Note that option (a) r = θ is incorrect because this would give the same angle as θ, not the reference angle. Option (c) r = θ - π is incorrect because it would give a negative angle, which is not an acute angle. Option (d) r = 2π - θ is incorrect because it would give an angle in the fourth quadrant, which is not the reference angle for an angle in the second quadrant.

so, 86 + sales tax (which is 5.16) = 91.16$
David only has 90$ so he can't afford the sneakers. They are 1.16$ over his budget.
While for Vincent,
9% of 86$ is 7.74$

A sales tax is a tax paid to a governing body for the income of certain items and services. Typically, legal guidelines permit the seller to gather funds for the tax from the customer at the factor of purchase. While a tax on goods or services is paid to a governing body immediately by means of a patron, it also includes called a use tax. frequently legal guidelines offer for the exemption of positive goods or services from income and use tax, which includes food, schooling, and medicines.

a line is perpendicular to y=-2x+5 and intersects the point (-4,2).What is the equation of this perpendicular line
Answer:
y = \(\frac{1}{2}\) x + 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 5 ← is in slope- intercept form
with slope m = - 2
given a line with slope m then the slope of a line perpendicular to it is
\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-2}\) = \(\frac{1}{2}\) , then
y = \(\frac{1}{2}\) x + c ← is the partial equation
to find c substitute the point (- 4, 2 ) into the partial equation
2 = \(\frac{1}{2}\) (- 4) + c = - 2 + c ( add 2 to both sides )
4 = c
y = \(\frac{1}{2}\) x + 4 ← equation of perpendicular line
a box with an open top and a square base is to be constructed to contain 4000 cubic inches. find the dimension that will require the minimum amount of material to construct the box.
The dimension of the box will be (40 inch × 40 inch × 10 inch).
How to determine the maximum and minimum values of an expression using differentiation?
Any given expression can have both minimum and maximum outcomes for any number in a real world scenario, which can be determined using differentiation; first order differentiation when equated to zero reveals the value that will solute to produce the maximum or minimum and then the upon differentiating the obtained expression again and then substituting the variable in acceptable positions, if the outcome is a positive number then the obtained number in first differentiation suggests a minimum value of the given expression.
Given, the volume of the box described = 4000 inch³
Let the dimension of the base of the box be = 'a' inch × 'a' inch = a² inch²
Therefore, height of the box = (4000 inch³)/(a² inch²) = (4000/a²) inch
Total surface area of the described box = S = a² + [4a×(4000/a²)]
= [a² + 16000/a] inch
For the limiting values of S, dS/da = 0 ⇒ d[a² + 16000/a]/da = 0
⇒ 2a - [16000/a²] = 0 ⇒ 2a = 16000/a² ⇒ a³ = 8000 ⇒ a = ∛8000 = 20
Therefore, the value of a is 20 inch.
Thus, height of the box = 4000/a² = 4000/400 = 10 inch
For S to have the minimum limited value, d²S/da² > 0 for a = 20 inch, which is satisfied by the available value of S.
∴ The minimal surface area = a² + 16000/a = 400 + (16000/400)
= 440 inch²
We are aware that the least amount of material will be needed to build the box when its overall surface area is the smallest.
Thus, to minimize the amount of material in consideration, the dimension of the box will be (40 inch × 40 inch × 10 inch).

the percentage of earthquakes recorded last year that had a magnitude of at least 5.6 was 29%. a seismologist is interested in the social impact of earthquakes and wishes to study these earthquake recordings. for what sample size, n, will the sampling distribution of sample proportions have a standard deviation of 0.05?
The sample size, n, required for the sampling distribution of sample proportions to have a standard deviation of 0.05 is 81,160.
It can be calculated by using the formula: `σ_p = √[p(1 - p)/n]`
Where:σ_p is the standard deviation of the sample proportion, p is the percentage of successes in the population, n is the sample size
First, we need to convert the given percentage to a decimal, which is:29% = 0.29
Next, we can substitute the values into the formula:0.05 = √[0.29(1 - 0.29)/n]
Squaring both sides, we get:0.0025 = 0.29(1 - 0.29)/n
Solving for n:
0.0025n = 0.29(1 - 0.29)
n = (0.29 × 0.71)/0.0025
n ≈ 81,160

The blood platelet counts of a group of women have a bell-shaped distribution with a mean of 258.1 and a standard deviation of 68.1. (All units are 1000 cells/muμL.) Using the empirical rule, find each approximate percentage below.
a.
What is the approximate percentage of women with platelet counts within 3 standard deviations of the mean, or between 53.8 and 462.4?
b.
What is the approximate percentage of women with platelet counts between 190.0 and 326.2?
a. According to the empirical rule,
for a bell-shaped distribution, approximately 68% of the data falls within one standard deviation of the mean,
approximately 95% falls within two standard deviations of the mean,
and approximately 99.7% falls within three standard deviations of the mean.
In this case, the mean is 258.1 and the standard deviation is 68.1. So, three standard deviations from the mean would be:
258.1 - 3(68.1) = 53.8
and
258.1 + 3(68.1) = 462.4
Therefore, approximately 99.7% of women have platelet counts between 53.8 and 462.4.
b. To find the percentage of women with platelet counts between 190.0 and 326.2, we need to standardize these values using the formula:
z = (x - μ) / σ
where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.
For the lower bound of 190.0:
z = (190.0 - 258.1) / 68.1 = -1.001
For the upper bound of 326.2:
z = (326.2 - 258.1) / 68.1 = 1.001
Using a standard normal distribution table or calculator, we can find the area under the curve between -1.001 and 1.001, which represents the percentage of women with platelet counts between 190.0 and 326.2. This area is approximately 68.2%.
Therefore, approximately 68.2% of women have platelet counts between 190.0 and 326.2.

The measure of length of the triangle is x = 6 cm
Given data ,
∆ABC~∆DEF , since ∆ABC and ∆DEF are similar triangles, their corresponding sides are proportional.
The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.
Let's denote the length of DE as x.
Given:
Area of ∆ABC = 64 cm²
Area of ∆DEF = 9 cm²
AB = 16 cm
The ratio of the areas is:
(Area of ∆ABC) / (Area of ∆DEF) = 64 / 9
