Katrina wants to buy a CD for $1000 that earns 2.5% APR and is compounded
quarterly. The CD matures in 5 years and the early redemption fee is 3
months' interest. If Katrina wants to take her money out 3 months before the
CD matures, how much money would she get back, after the early redemption
fee?
O A. $1119.42
O B. $1226.71
O c. $1025.39
O D. $1031.64
Answer:
1119.42
Step-by-step explanation:
Final answer:
Katrina would receive an amount closest to $1,119.42, thus option A is the closest answer.
Explanation:
Katrina is looking at a Certificate of Deposit (CD) which has certain terms for compounded interest and an early redemption fee. To calculate how much she would get back if she withdraws the money 3 months before the CD matures, we need to do the following steps:
Calculate the compounded amount of the CD after 4.5 years since it is compounded quarterly.Calculate the interest for 3 months (1 quarter).Subtract the 3 months' interest from the total compounded amount to account for the early redemption fee.The formula for compounded interest is [tex]A = P(1 + r/n)^{(nt)}[/tex], where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of times that interest is compounded per year.t is the time the money is invested for, in years.For this problem:
P = $1000r = 0.025 (2.5% annual interest rate)n = 4 (compounded quarterly)t = 4.5 years (since we are calculating for 3 months before the 5 years)Let's calculate:
A = $[tex]\$1000(1 + 0.025/4)^{(4*4.5)}[/tex] = A ≈ $1,131.64
Now we calculate the 3 months' interest which is essentially the interest for one quarter:
Interest for one quarter = (A for 4.75 years) - (A for 4.5 years)
We calculate A for 4.75 years using t = 4.75 and subtract A for 4.5 years:
A for 4.75 years = [tex]\$1000(1 + 0.025/4)^{(4*4.75)}[/tex] ≈ $1,144.12
Interest for one quarter = $1,144.12 - $1,131.64 ≈ $12.48
Finally, subtracting the early redemption fee:
Amount after fee = $1,131.64 - $12.48 ≈ $1,119.16
The actual amount after subtracting the early redemption fee from the compounded total closest matches option A. $1119.42.

Do these side lengths form a triangle?
Add the two smaller numbers: 3 + 7 = 10
Since 10 is greater than 9, these three side lengths do form a triangle.
Now we qualify the triangle.
c^2 ? a^2 + b^2
The ? is there because we don';t know yet if it will be =, >, or <.
9^2 ? 3^2 + 7^2
81 ? 9 + 49
81 ? 58
Since 81 is greater than 58, now we know to use >.
81 > 58
Since c^2 is greater than a^ + b^2, the triangle is obtuse.
Answer: Yes these side lengths form a triangle, and the triangle is obtuse.

an angle measure of 55.45 is converted to DMS notation as
Converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds
Step-by-step explanation:
We need to convert angle measure of 55.45 to DMS notation
DMS notation is Degree Minute and seconds
Solving:
We have 55.45, the value before decimal is considered as degrees and values after decimal can be minutes and seconds.
We can write it as 55 and 0.45
So, we have 55 degrees
To find minutes we will multiply 0.45 by 60
0.45*60 = 27 minutes
Since we have no decimal value in minutes so seconds will be 0
So, DMS will be 55 degrees 27 minutes 0 seconds
Hence converting angle measure of 55.45 to DMS notation we get 55 degrees 27 minutes 0 seconds
John has 1 ½ hours of homework each day from Monday through Friday and 2 ¾ hours over the weekend. How much work does John have in a week?
Answer:
10.25 (10 1/4)
Step-by-step explanation:
1 1/2 = 1.5
Monday through Friday = 5 days.
1.5 hours of homework times 5 = 7.5
2 3/4 = 2.75 (his homework over the weekend)
7.5 plus 2.75 = 10.25
John would have 10.25, or 10 1/4 hours in a week.
Final answer:
John has 10.25 hours of homework in a week by calculating his daily homework hours and weekend hours.
Explanation:
To calculate the total amount of homework John has in a week:
John has 1 ½ hours of homework each day from Monday through Friday, totaling 1.5 hours/day x 5 days = 7.5 hours.
John has 2 ¾ hours over the weekend, which is 2.75 hours.
Adding the weekday and weekend hours together, John has a total of 7.5 hours + 2.75 hours = 10.25 hours of homework in a week.

The number of people who receive Nicholas's chain letter can be modeled by an exponential growth function. Every 12 weeks, the number of people who have received the letter can be calculated by the formula P(t) = P0(1 + 0.99)^t, where P0 is the initial number of people, and t is the time in weeks.
Explanation:The number of people who receive Nicholas's chain letter is represented by the function P(t) = P0(1 + r)^t, where P0 is the initial number of people, r is the rate of increase (expressed as a decimal), and t is the time in weeks. In this case, r is equal to 99%, or 0.99. So every 12 weeks, the number of people who have received the letter can be modeled as P(t) = P0(1 + 0.99)^t. This is an example of an exponential growth function, which is often used in real-world scenarios where the rate of something increases rapidly, such as interest in a bank account or population growth.

Which unit would you need fewer of to measure a tree?
To measure the height of a tree, feet would be the most suitable unit .
When determining which unit you would need fewer of to measure a tree, it's important to consider units that are an appropriate scale for the object in question. Since a tree is typically more than a few feet tall, but significantly less than a mile tall, we would use feet as the unit of measurement. Using yards would require us to measure in much smaller segments than a whole yard, and using inches would take a long time to measure the full height. Therefore, the most suitable unit to measure the height of a tree would be feet, as this unit provides a balance between precision and efficiency. For fieldwork where estimation of tree density is needed, aspects like basal area might be measured using a factor prism in a defined plot area, such as a 0.04-ha (0.1-acre) plot, to estimate the density of trees in a larger area.
How does the sign of a affect the domain and range of ()=?f of , open x close . equals eh , x squared , question mark
Answer:
(See explanation for further details).
Step-by-step explanation:
The sign does not affect the domain, as second-order polynomials are continuous functions. Nonetheless, the sign affect the range of function in the sense that elements can be lesser and equal to zero (a < 0) or greater and equal to zero (a > 0).
The sign of 'a' in the function f(x) = ax2 affects the direction the parabola opens, influencing the range of the function, either [0, ∞) for a positive 'a' or (-∞, 0] for a negative 'a'. The domain, which is always (-∞, ∞), isn't affected by 'a's sign.
Explanation:In mathematics, the function f(x) = ax2 is a quadratic function where 'a' is the coefficient of x2. The sign of 'a' determines whether the parabola opens upward or downward. When 'a' is positive, the parabola opens upward hence making the range of the function [0, ∞) because the lowest point (vertex) is on the x-axis and it extends to positive infinity. If 'a' is negative, the parabola opens downward, and the range becomes (-∞, 0] as the highest point is on the x-axis and it extends to negative infinity.
The domain of f(x) = ax2 does not depend on the 'a' value; it is always all real numbers because x can be any real number regardless of the value of 'a'. Therefore, the domain is always (-∞, ∞).

A barge that is used to transport wheat is the shape of a rectangular prism and is 90 feet long, 35 feet wide, and 12 feet deep. What volume of wheat can the barge hold?
Answer: 37,800
Step-by-step explanation: 35x90x12= 37,800
Final answer:
The barge, which is shaped like a rectangular prism and measures 90 feet in length, 35 feet in width, and 12 feet in depth, can hold up to 37,800 cubic feet of wheat.
Explanation:
To determine the volume of wheat that a rectangular prism-shaped barge can hold, we use the formula for the volume of a rectangular prism: Volume = length × width × height. Given that the barge is 90 feet long, 35 feet wide, and 12 feet deep, we calculate the volume as follows:
Volume = 90 feet × 35 feet × 12 feet
Volume = 37,800 cubic feet
Therefore, the barge can hold up to 37,800 cubic feet of wheat.

Zack, Jack and Sasha earned £250 altogether delivering leaflets.
Zack delivered 50%.
Jack delivered 30%.
Sasha delivered 20%.
They are each paid according to the number of leaflets they delivered.
How much did each person earn?
Answer:
Zack earned £125, Jack earned £75, and Sasha earned £50
Step-by-step explanation:
Considering the number of leaflets delivered
Zack 50%, Jack 30% and Sasha 20%
Total delivered = 50 + 30 + 20 = 100%
If they earn £250 on the 100% delivery, then each will have as shown below
Zack = (50/100)*250
= 5*25
= £125
Jack = (30/100)*250
= 3*25
= £75
Sasha = (20/100)*250
=2*25
= £50
Answer:
£125, £75 and £50
Step-by-step explanation:
Zack delivered 50%
Therefore, Zack earned
50% of £250
50/100 x £250
0.5 x 250
£125
Zack earned £125
Jack delivered 30%, therefore
Jack earned
30% of £250
0.3 x £250
£75
Jack earned £75
Sasha delivered 20%
Therefore, Sasha earned 20% of £250
20/100 x £250
0.2 x £250
£50
Sasha earned £50
Zack + jack + Sasha = £250
£125 + £75 + £50 = £250
y = -x^2 + 6x - 5 , zeros
Answer:
x = 1, x = 5
Step-by-step explanation:
To find the zeros let y = 0, that is
- x² + 6x - 5 = 0 ( multiply through by - 1 )
x² - 6x + 5 = 0 ← in standard form
(x - 1)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x - 5 = 0 ⇒ x = 5
