The change referred to in the headline is an absolute change. An absolute change is a difference or increase in a quantity that is measured without reference to the original or initial value.
In this case, the headline states that enrollments at Northeastern University are expected to increase by 1,700 students. This means that the actual number of students is expected to increase by 1,700 from its current or previous level, without any reference to the original number of students enrolled at Northeastern University.
An absolute change is usually expressed in units of the quantity being measured, such as students, dollars, or meters. In contrast, a relative change is expressed as a percentage or ratio of the original or initial value. A relative change indicates how much a quantity has changed in proportion to its initial value.
For example, if enrollments at Northeastern University were expected to increase by 10%, this would be a relative change because it represents a percentage of the current or previous level of enrollment. However, the headline specifies an absolute increase of 1,700 students, which does not depend on the current or previous level of enrollment.

A plane cruising at an altitude of km starts descending so that its altitude decreases at the rate m/min. Find the equation for its altitude h (in m) as a function of time t and sketch the graph for t0 to t10 min.
The equation for its altitude h (in m) as a function of time t is h(t) = h₀ x 1000 - rt and the graph of the equation is illustrated below.
Let's begin by defining our variables. We know that the initial altitude of the airplane is given as h₀, which is in km. We also know that the rate at which the altitude decreases is given as r, which is in m/min. Our objective is to determine the altitude h of the airplane at any given time t, in minutes, during the descent.
To find the equation for the altitude of the airplane, we need to first convert the initial altitude from km to m. This can be done by multiplying h₀ by 1000. Therefore, the initial altitude in meters is h₀ × 1000.
Finally, we can find the equation for the altitude of the airplane by subtracting the amount that the altitude has decreased from the initial altitude. This gives us the following equation:
h(t) = h₀ × 1000 - rt
where h(t) is the altitude of the airplane at time t, h₀ is the initial altitude in km, r is the rate of descent in m/min, and t is the time in minutes.
To sketch the graph of this equation, we can plot altitude on the y-axis and time on the x-axis. Then we get the graph like the following.

Given NE and TE are tangents to the circle below, what is the length of segment NE
If "NE" and "TE" are tangents of circle, then length of segment NE is 53 units.
We find the length of the segment "NE" by using the fact that tangents drawn to a circle from an external point are equal in length.
So, We have,
⇒ NE = TE ...(because they are tangents to the same circle from the same external point E),
So we can set the "two-expressions" of tangent equal to each other:
We get,
⇒ 13x - 12 = 7x + 18,
⇒ 6x - 12 = 18,
⇒ 6x = 30,
⇒ x = 5,
now, we substitute the value of x in "NE", to find the length of segment NE.
We get,
⇒ NE = 13x - 12,
⇒ NE = 13(5) - 12,
⇒ NE = 65 - 12,
⇒ NE = 53.
Therefore, length of NE is = 53 units.

If you want to earn 2% annual simple interest on an investment, how much should you pay for a note that will be worth $15,500 in 10 months? (Round your answer to two decimal places.)
Answer:
Step-by-step explanation:
To solve this problem, we can use the simple interest formula:
I = P*r*t
where I is the interest earned, P is the principal (the initial investment), r is the interest rate (as a decimal), and t is the time (in years).
Here, we want to find P, so we'll rearrange the formula:
P = I/(r*t)
We know that the final value of the investment (including interest) is $15,500, and the time is 10 months (or 10/12 years). We can plug in the numbers:
I = $15,500 - P
r = 0.02
t = 10/12
P = (15,500 - P)/(0.02*(10/12))
P = (15,500 - P)/(0.1667)
P = 93,000 - 6P
7P = 93,000
P = $13,285.71
Therefore, you should pay $13,285.71 for the note if you want to earn 2% annual simple interest and have it be worth $15,500 in 10 months.

A passbook savings account has a rate of 5%. Find the effective annual yield, rounded to the nearest tenth of a percent, if the interest is compounded semiannually.
Answer: 5.1%
Step-by-step explanation:
The formula for calculating the effective annual yield when the interest is compounded semiannually is given by:
(1 + (r/n))^n - 1
where r is the annual interest rate and n is the number of times the interest is compounded in a year.
In this case, r = 5% and n = 2 (since the interest is compounded semiannually). Substituting these values into the formula, we get:
(1 + (0.05/2))^2 - 1
= (1.025)^2 - 1
= 1.050625 - 1
= 0.050625
Multiplying this value by 100 gives the effective annual yield as a percentage:
0.050625 x 100 = 5.0625%
Rounding this to the nearest tenth of a percent, we get:
Effective annual yield = 5.1%
Therefore, the effective annual yield for the given savings account, rounded to the nearest tenth of a percent, is 5.1%.

According to the USDA, a small family farm has an average area of 231 acres.
a. What is this area in square miles? Use this fact that 1 square mile is 640 acres.
b. What is this area in square feet? Recall: 1 mile = 5,280 ft.
Answer:
Therefore, the area of a small family farm in square feet is 9,923,640.
Step-by-step explanation:
a. To convert acres to square miles, we divide the number of acres by 640:
231 acres / 640 acres/square mile = 0.36 square miles
Therefore, the area of a small family farm in square miles is 0.36.
b. To convert acres to square feet, we first need to convert acres to square yards (since there are 9 square feet in a square yard):
231 acres x 4840 square yards/acre x 9 square feet/square yard = 9,923,640 square feet
Therefore, the area of a small family farm in square feet is 9,923,640.
good buy electronics has a markup of 150% on a keyboard that cost the retailer $25. find the retail "selling" price and show your work
The retail selling price of the keyboard is $43.75.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
To find the retail selling price of the keyboard, we need to add the markup to the cost of the keyboard.
The markup of 150% means that the retailer is adding 150% of the cost to the selling price.
To calculate this, we can first find the dollar amount of the markup:
Markup = 150% of $25
Markup = 0.5 * 150 * $25
Markup = $18.75
This means that the retailer is adding $18.75 to the cost of the keyboard to get the selling price. To find the selling price, we can add the markup to the cost:
Selling price = Cost + Markup
Selling price = $25 + $18.75
Selling price = $43.75
Therefore, the retail selling price of the keyboard is $43.75.
