Answer:
the answer is E
Step-by-step explanation:
Consider the function defined by f(x) for x > 0 and its graph y = f(x).
The graph of f has a horizontal tangent at point P. Find the coordinates of P.
This means that the coordinates of P are (a, b), where a is the value for which f'(a) = 0, and b = f(a).
What is coordinate?The term "coordinate" generally refers to a value or set of values that describe the position or location of a point or object in a particular system or space. In mathematics, coordinates are typically used to describe the position of a point on a graph or in a geometric plane, and they usually consist of a set of numerical values that indicate the distance or direction of the point from a specified origin or reference point. In geographic or cartographic contexts, coordinates might refer to latitude and longitude values that indicate a specific location on the Earth's surface. Other systems may use different types of coordinates, but the underlying idea is usually the same: a set of values that describe the position of an object or point in a given space or system.
if the graph of f has a horizontal tangent at point P, this means that the slope of the tangent line at P is zero.
Let (a, b) be the coordinates of P. Then the equation of the tangent line at P is:
[tex]y - b = f'(a)(x - a)[/tex]
Since the slope of the tangent line at P is zero, we have:
f'(a) = 0
This means that the derivative of f at x = a is zero. So, we need to find the value of a for which f'(a) = 0.
Once we find the value of a, we can substitute it into the equation of the tangent line to find the value of b.
So, let's find f'(x) first:
f(x) = ... (the function is not given, so we cannot find f'(x) explicitly)
We know that f'(a) = 0, so we have:
[tex]f'(a) = lim h- > 0 [f(a+h) - f(a)]/h = 0[/tex]
This means that:
[tex]lim h- > 0 [f(a+h) - f(a)]/h = 0[/tex]
Multiplying both sides by h, we get:
[tex]lim h- > 0 [f(a+h) - f(a)] = 0[/tex]
Taking the limit as h approaches 0, we get:
[tex]f(a) - f(a) = 0[/tex]
So, we have:
[tex]f(a) = b[/tex]

Where the above information about right triangles are given, the asnswer is
A. x = 3, y = 2 (Option A)
How did we arrive at the above?The hypotenuse and the length of one leg of one right triangle must be equal to the hypotenuse and corresponding length of the one leg of the other ∆ for both triangles to be equal by the HL Congruence Theorem.
Thus, let's find x and y by setting the corresponding lengths of the two right ∆s equal to each other.
Therefore:
x = y + 1 ----› eqn. 1
2x + 3 = 3y + 3 ----› eqn. 2
Substitute x = (y + 1) into eqn. 2, and solve for y.
2x + 3 = 3y + 3 ----› eqn. 2
2(y + 1) + 3 = 3y + 3
2y + 2 + 3 = 3y + 3
2y + 5 = 3y + 3

What is an Ackermann function?The idea of a fully computable function that is not primitive recursive is illustrated by the recursively constructed mathematical function known as the Ackermann function. Since m and n are non-negative integers, it is commonly written as A(m, n).
a.) Prove using regular induction that [tex]A(1, n) \leq 2^n[/tex] for all positive integers n:
Base Case: For n = 1, A(1, 1) = 2, which is equal to [tex]2^1[/tex].
Inductive Hypothesis: Assume that [tex]A(1, k) \leq 2^k[/tex] for some positive integer k.
Inductive Step: We need to show that [tex]A(1, k + 1) \leq 2^{(k + 1)}[/tex]. Using the recursive definition of A(m, n), we have [tex]A(1, k + 1) = A(0, A(1, k)) = 2^{(A(1, k))}\leq 2^{(2^k)}[/tex] (by inductive hypothesis)[tex]< = 2^{(2^{(k + 1)})}[/tex].

1. A train travels 16.8 km in 25 minutes. Find the speed of the train in (i) km/h, (ii) m/s. f 55 km/h. Find the distance travelled bynumber, opinion, size, shape, condition, age, color, pattern, origin, materials, and purpose.04-Jan-2022
the speed of the train in km/h is 40.32 whereas the speed of the train in m/s is 11.2.
(i) To find the speed of the train in km/h, we can use the formula:
speed = distance/time
Here, the distance travelled by the train is 16.8 km, and the time taken is 25 minutes, which is equivalent to 0.4167 hours (since 1 hour = 60 minutes). Substituting these values in the formula, we get:
speed = 16.8 km/0.4167 hours
speed = 40.32 km/h (rounded to two decimal places)
Therefore, the speed of the train in km/h is 40.32.
(ii) To find the speed of the train in m/s, we can convert the speed in km/h to m/s by multiplying by 1000/3600 (since 1 km/h = 1000 m/3600 s). Using the speed of 40.32 km/h from part (i), we get:
speed = 40.32 km/h * 1000 m/km / 3600 s/h
speed = 11.2 m/s (rounded to one decimal place)
Therefore, the speed of the train in m/s is 11.2.
If the speed limit is 55 km/h, we cannot directly determine the distance travelled by the train without additional information. The distance travelled by the train would depend on the time it took to travel at the given speed limit.

Note: Do not round intermediate calculations. Round the "Interest" and "Maturity value" to the nearest cent.
A loan of $595 borrowed on June 15 and repaid on Dec 17 at an exact interest rate of 6%. The exact time between the two dates is 170 days, and the maturity value is $611.69 rounded to the nearest cent.
Using the Days in a year table, we can find the exact time between June 15 and December 17 as follows
June has 30 days in the table and July through November have 31 days each. December has 17 days until the loan is repaid. Therefore, the exact time is
30 + 31 + 31 + 30 + 31 + 17 = 170 days
Next, we can calculate the interest using the formula
interest = principal x rate x time / 365
where the principal is $595, the rate is 6%, and the time is 170 days.
Substituting these values, we get
interest = 595 x 0.06 x 170 / 365
interest = $16.69
Therefore, the exact interest is $16.69.
Finally, we can calculate the maturity value by adding the principal and the interest
maturity value = principal + interest
maturity value = $595 + $16.69
maturity value = $611.69
Therefore, the maturity value is $611.69 rounded to the nearest cent.

At the park there is a pool shaped like a circle with diameter 22 yd. A ring-shaped path goes around the pool. Its
width is 5 yd. If one gallon of coating can cover 5yd many gallons of coating do we need? Note that coating comes only by the gallon so the number of gallons must be a whole number. (Use the value 3.14 for pi.)
Answer: To find the area of the ring-shaped path, we need to subtract the area of the inner circle (the pool) from the area of the outer circle. The radius of the pool is half the diameter, so it is 11 yards. The radius of the outer circle is the sum of the radius of the pool and the width of the path, so it is 11 + 5 = 16 yards.
The area of the pool is:
A_pool = pi * r^2 = pi * 11^2 ≈ 380.13 square yards
The area of the outer circle is:
A_outer = pi * R^2 = pi * 16^2 ≈ 804.25 square yards
The area of the ring-shaped path is:
A_path = A_outer - A_pool ≈ 804.25 - 380.13 ≈ 424.12 square yards
Since one gallon of coating can cover 5 square yards, we need:
Gallons = A_path / 5 ≈ 424.12 / 5 ≈ 84.82
Therefore, we need approximately 85 gallons of coating to cover the ring-shaped path.

what is the equation that best models the data from the table after the data has been linearized? a. log y = 0.116315x+0.249114
b. log y = 0.249114x+0.116315
c. log y = 0.0288761x+0.435269
d. log y = 0.435269x+0.0288761
Okay, let's analyze the linearized data options to determine which equation best models it:
a. log y = 0.116315x+0.249114
This has a positive slope coefficient of 0.116315, so it will model increasing data. But the y-intercept term 0.249114 is negative, so the model line would start below the origin. This does not seem to match the typical linear relationship we would expect.
b. log y = 0.249114x+0.116315
This also has a positive slope coefficient, but now the y-intercept term 0.116315 is positive. This could potentially model increasing data that starts above the origin. However, without seeing the data it's hard to definitively say if this is the best fit.
c. log y = 0.0288761x+0.435269
This has a positive but much smaller slope coefficient of 0.0288761. This would model increasing data at a much shallower rate. Again, without seeing the data we can't rule this out, but it seems less likely.
d. log y = 0.435269x+0.0288761
This has a larger positive slope coefficient of 0.435269, so it would model increasing data at a steeper rate. And the positive y-intercept term of 0.0288761 ensures the model line starts above the origin.
Of these 4 options, choice d (log y = 0.435269x+0.0288761) seems the most likely to best model increasing linear data that starts above the origin. However, without seeing the actual data points, we can't say that with certainty. The slope and intercept values would need to give the closest fit to the data for that to be the definitive choice.

3. 108 goldfish were given away all day
4. Yes the owner have enough goldfish for the entire day
5. 16 goldfish were left over
How to solve for the goldfish2. Before noon, gold fish = 30 + 36 + 40 = 106
after noon gold fish = 28 + 30 + 10 + 2 + 8 = 78
diference = 106 - 78
= 28
3. Gold fish given away all day = 106 + 78
= 184
4. The owner had enough fish because the total fist he had was 200 and the amount that was given away is 184
5. The left over fish = 200 - 184
= 16

Directions: Molly collected data from her friends. Each friend told her the number
of hours they slept last night. Use the information in the chart below to complete a
line plot of the data. Determine the scale you should use, and a title for the line
plot. Using the blank line plot below, write in the intervals, the title you chose, and
place a dot on the line plot for each of Molly’s friend’s hours of sleep. Then, answer
the questions about the line plot you’ve created.
The most common amount of sleep is 8 1/2 hours.
There is no outlier in the data.
The difference in hours between the longest night's sleep and the longest night's sleep is 3.5 hours.
The number of people who slept longer than 8 hours is 15 people.
What is a dot plot?In Mathematics and Statistics, a dot plot can be defined as a type of line plot that is typically used for the graphical representation of a data set above a number line, especially through the use of crosses or dots.
Based on the information provided about the number of hours Molly's friends slept last night, we can reasonably infer and logically deduce that all of the data points would be between 6 and 11, without any outlier.
In this scenario, we would use an online graphing calculator to construct a dot plot with respect to a number line that accurately fit Molly's data set, with a scale of 0 < x < 11.
Difference in hours = 10 - 6.5 = 3.5 hours.
In conclusion, the dot plot would be titled "Hours of sleep."

What is the factored form of 8x24-27y6?
o (8x-27y2) (2x¹+xy+3y*)
ọ (2x³− 3y²)(4x¹6−6x³y² +9y4)
0 (2x³-3y²) (4x¹6 +6x³y² +9yª)
(8x-27y²) (2x¹6-Bxy+3y4)
The factored form of [tex]8x^{2} 4 - 27y^{6}[/tex] 8x²4 - 27y⁶
To factor this expression, that it is in the form of a difference of two squares.
Specifically, 8x²4 is equal to (2x²)³ and 27y⁶ is equal to (3y²)³.
the formula for the difference between two cubes, states that:
[tex]a^3 - b^3 = (a - b)(a^2 + ab + b^2)[/tex] (a³ - b³ = (a - b)(a² + ab + b²)
Substituting [tex]a = 2x^2[/tex] a = 2x² and [tex]b = 3y^2[/tex] b = 3y², gives
[tex]8x^24 - 27y^6 = (2x^2)^3 - (3y^2)^3= (2x^2 - 3y^2)(4x^2 + 6x^2y^2 + 9y^4)[/tex]
8x²4 - 27y⁶ = (2x²)³ - (3y²)³ = (2x² - 3y²)(4x⁴ + 6x²y² + 9y⁴)
Therefore, the factored form of [tex]8x^{2} 4 - 27y^{6}[/tex] 8x²4 - 27y⁶ is [tex](2x^2 - 3y^2)(4x^4 + 6x^2y^2 + 9y^4).[/tex](2x² - 3y²)(4x⁴ + 6x²y² + 9y⁴).
