(b) The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.
Comparing the functions f(x) and g(x)From the question, we have the following parameters that can be used in our computation:
f(x) = x²
g(x) = (1/5x)²
The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.
To see this, we can rewrite g(x) as g(x) = (1/5)²(x²) = (1/5²)f(x).
This means that g(x) is equal to f(x) scaled vertically by a factor of 5² = 25.
Therefore, the graph of g(x) will be the same shape as the graph of f(x), but stretched vertically by a factor of 25.

To calculate the area of a sector, we can use the formula:
A = (θ/2) * r^2
where:
A is the area of the sector,
θ is the central angle of the sector in radians, and
r is the radius of the sector.
Given:
r = 2 (radius)
θ = 1.75 radians (central angle)
Plugging in the given values into the formula:
A = (1.75/2) * 2^2

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.

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.

Main body:
A parametric curve is a function expressed in components form, such that;
x = f(t) , y = g(t).
The length of a parametric curve on the interval a ≤ t ≤ b is given by the definite integral :
L = [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx[/tex]
Let's begin by getting the first derivative of the components of the function with respect to the variable t.
x = e^t - t
dx / dt = e^t−1
And, y = 4 e^t/2
dy /dt = 2 e^t/2
Substitute the derivatives into the following definite integral which computes the length of the parametric curve on the interval
[a,b]=[0,2].
L = [tex]\int\limits^a_b {\sqrt{\frac{dx}{dt}^2 + {\frac{dy}{dt}^2 } } } \, dx[/tex]
L= [tex]\int\limits^2_0 {\sqrt{\ (e^t - 1)^2 + ({\(2e^{t/2}) ^2 } } } \, dx[/tex]
L = [tex]\int\limits^2_0 {e^t - 1} \, dx[/tex]
Evaluate the solution at the limits of integration to get the length.

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 spherical tank of radius 8 feet is half full of oil that weighs 50 pounds for cubic font .find the work required to pump the oil out through a hole to the top of the tank.
The work required to pump the oil out through a hole to the top of the tank is approximately 6,476,160π/3 foot-pounds.
To solve this problemWe can find the work required to pump the oil out of the tank by using the formula:
W = ∫[V1, V2]ρgh dV
Where
W is the work required (in foot-pounds)ρ is the density of the oil (in pounds per cubic foot)g is the acceleration due to gravity (in feet per second squared)h is the height of the oil column being pumped (in feet)dV is an infinitesimal volume elementFirst, we need to find the density of the oil. We are told that the oil weighs 50 pounds per cubic foot, so:
ρ = 50 lb/ft^3
Next, we need to find the height of the oil column being pumped. The tank is half full, so the height of the oil column is:
h = r - (r/2) = r/2 = 8/2 = 4 feet
Now, we need to find the volume of oil being pumped. Since the tank is half full, the volume of oil is:
V = (1/2)(4/3)πr^3 = (1/2)(4/3)π(8)^3 = 1,024π/3 cubic feet
Finally, we can integrate the work formula to find the total work required:
W = ∫[V1, V2]ρgh dV
W = ∫[0, 1,024π/3] (50 lb/ft^3)(32.2 ft/s^2)(4 ft) dV
W = (6,476,160π/3) ft-lb
Therefore, the work required to pump the oil out through a hole to the top of the tank is approximately 6,476,160π/3 foot-pounds.

Find the amount spent on advertising that will yield a monthly profit of $9,000
The amount spent on advertising that will yield a monthly profit of $9,000 is $8.57.
What is profit?Profit is the amount of money or financial gain that a business or an individual makes after deducting all the expenses and costs associated with producing or providing a product or service.
According to question:According to the model, the profit P (in dollars) is dependent on the sum x (in dollars) that the business invests in advertising:
P = 130x² - 550
We want to find the amount spent on advertising that will yield a monthly profit of $9,000. In other words, we want to solve for x when P = 9000:
130x² - 550 = 9000
Adding 550 to both sides, we get:
130x² = 9550
Dividing both sides by 130, we get:
x² = 73.46
x = ±8.57
Since we are dealing with a real-world scenario, the amount spent on advertising must be a positive value. Therefore, we take the positive root:
x = 8.57
Therefore, the amount spent on advertising that will yield a monthly profit of $9,000 is $8.57.

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.

What is probability distribution?A discrete random variable with a countable number of potential values is said to have a discrete probability distribution. Each possible value of the random variable is given a probability by the probability distribution, and the sum of these probabilities is 1. The number of heads you get while flipping a coin or the number of cars that pass through a specific crossroads in a given hour are both examples of discrete random variables.
The mean that Luke will hit the inner ring is given as:
E(X) = np

Into how many regions, or parts, do two lines that are in general position divide a plane?
Answer:
Two lines that are in general position divide a plane into four regions or parts.
When two lines intersect at a point, they divide the plane into four distinct regions, called quadrants. However, if the two lines are parallel, they do not intersect, and the plane is divided into only two regions, called half-planes.
In general position, two lines in a plane have different slopes and different y-intercepts, which means that they are neither parallel nor coincident. Therefore, the two lines must intersect at a point, dividing the plane into four regions.

which states that the dimension of patients who show cut down blood pressure is the same for the two doses of the drug (50 mg and 100 mg).
Popular test statistics like the z-test can be applied to this hypothesis test and other statistical analyses.
[tex]z = (p1 - p2) / SE[/tex]
where p1 and p2, for the 50 mg and 100 mg doses, respectively, are the sample proportions of patients who show fallen blood pressure, and SE is the standard error of the difference between the proportions.
the samples are assumed to be independent or dependent, impacts the SE formula. The samples in this instance are presumed to be independent because they came from various patients. Consequently, the equation for SE is:
[tex]SE = \sqrt(p1 \times (1 - p1)/n1 + p2 *\times(1 - p2)/n2)[/tex]
here, the sample sizes for two doses is n1 and n2.
We can compute the z-test statistic based on the sample sizes and proportions and compare the result to a critical value or p-value to decide whether to accept or reject the null hypothesis.
Therefore, a z-test for the proportional difference is the proper hypothesis test.
