The equation of the tangent line at x = 16 is therefore :y - 2 = (1/64)(x - 16)Simplifying, we get :y = (1/64)x + 1Using this equation, we can estimate the value of 12^1/4:y = (1/64)(12) + 1 = 49/32Therefore, the estimate for 12^1/4 using linear approximation is 49/32.
approximation is an approach used to estimate the value of a function at a point near a known point by using the linear equation tangent to the function at that point.
This technique is commonly used in physics, engineering, economics, and other fields where mathematical models are used to describe real-world phenomena.
To estimate 12^1/4 using linear approximation, we first need to find the equation of the tangent line at the point of interest, which is x = 16 (since 16^4 = 2^16 = 65536).
Then, we can use the equation of the tangent line to estimate the value of the function at a nearby point, which in this case is x = 12.
We can find the equation of the tangent line using the derivative of the function :f(x) =[tex]x^1/4f'(x) = (1/4)x^-3/4At x = 16:f(16)[/tex] = 2f'(16) = (1/4)(16)^-3/4 = 1/64

Let f(x)=x2−4. What is the average rate of change of f(x) from −5 to −2 ?
A. -1/7
B. 1/7
C. -7
D. 7
Answer:
Step-by-step explanation:
To find the average rate of change of the function f(x) from -5 to -2, we need to calculate:
(f(-2) - f(-5))/(-2 - (-5))
First, let's find f(-2) and f(-5):
f(-2) = (-2)^2 - 4 = 0
f(-5) = (-5)^2 - 4 = 21
Substituting these values in the above formula, we get:
(0 - 21)/(-2 + 5) = -21/3 = -7
Therefore, the average rate of change of f(x) from -5 to -2 is -7.
So the answer is (C) -7.

What is tangent?Tangent is a line or plane that touches a curve or surface at a single point. It is a measure of the steepness of a curve or surface at a particular point. It is equal to the ratio of the change in the y-coordinate to the change in the x-coordinate of a point on the curve. Tangent is used in many areas of mathematics and physics, including calculus, geometry, and mechanics. It is also used to describe the rate of change in a function, as well as to define the angle between two intersecting lines.
The tangent line equation for a line with a slope of 50 degrees is y = tan(50°)x.
To solve for x, you must rearrange the equation to isolate x on one side of the equation.
To do this, divide both sides of the equation by tan(50°), giving the equation x = y/tan(50°). This equation shows that the value of x is equal to the y-value divided by the tangent of 50°.

Answer:
To find the area of the given figure, we can divide it into two separate shapes, a rectangle and a triangle, and then add their areas together.
First, we can find the area of the rectangle by multiplying its length and width. From the diagram, we can see that the length of the rectangle is 12 cm and the width is 5 cm.
Area of rectangle = length x width
Area of rectangle = 12 cm x 5 cm
Area of rectangle = 60 cm^2
Next, we can find the area of the triangle by using the formula for the area of a triangle, which is:
Area of triangle = 1/2 x base x height
From the diagram, we can see that the base of the triangle is 5 cm and the height is 8 cm.
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 cm x 8 cm
Area of triangle = 20 cm^2
Finally, we can find the total area of the figure by adding the area of the rectangle and the area of the triangle:
Total area = area of rectangle + area of triangle
Total area = 60 cm^2 + 20 cm^2
Total area = 80 cm^2
Therefore, the area of the given figure is 80 square centimeters.

a 12 cm tall and radius of 10 cm cylinder is filled with 10 cm of water.
a) Rotational speed at which the water just touches the bottom of the cylinder:
We will use the formula for centripetal force for a liquid with the volume of a cylinder to obtain the rotational speed at which the water just touches the bottom of the cylinder.
The formula for centripetal force for a liquid with the volume of a cylinder is as follows:
F = (ρr²πh)ω²WhereF:
Centripetal forceρ: Densityr: Radiush : Heightω: Rotational speed Substituting the given values,
we get: F = (1000 kg/m³ × (0.1m)² × π × 0.12m)ω²F
= 377 Nω
= √(F/m)ω
= √(377 N/ 10 kg)ω
= √37.7ω = 6.14 rad/sb)
Pressure at points A and B:
We will use the formula for hydrostatic pressure for a liquid to calculate the pressure at points A and B. The formula for hydrostatic pressure for a liquid is as follows:
P = ρgh
Where,
P: Pressureρ: Densityg: Acceleration due to gravity: DepthSubstituting the given values for point A,
we get P = 1000 kg/m³ × 9.8 m/s² × 0.1 mP
= 980 Pa
Substituting the given values for point B,
we get P = 1000 kg/m³ × 9.8 m/s² × 0.22 mP
= 2156 Pa

What is median ?
The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, median is helpful. The median is one of the simple to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the centre of a sequence to determine its value.
To calculate the cumulative frequency, we add the frequency of each class interval to the sum of frequencies of all previous class intervals.
Height, h in cm Frequency Cumulative Frequency
0 1 1
10 < h < 20 9 10
20 < h < 30 7 17
30 < h < 40 13 30
The total frequency is 30, which is an even number. To find the median, we need to find the value that lies in the middle of the dataset. Since the total frequency is even, the median will be the average of the two middle values.
The two middle values will be the 15th and 16th value. To find the corresponding class interval, we look at the cumulative frequency column and find the interval that contains the 16th value.
The 16th value is in the "30 < h < 40" interval, which means that this interval contains the median.
Therefore, the class interval that contains the median is "30 < h < 40".

calculate the centripetal force (in n) on the end of a 52 m (radius) wind turbine blade that is rotating at 0.3 rev/s. assume the mass is 2 kg
The centripetal force is 7384.80 N.
For the centripetal force in N on the end of a 52 m (radius) wind turbine blade that is rotating at 0.3 rev/s and assuming the mass is 2 kg.
Use the following formula:
Centripetal force = (mass x velocity²) / radius
Where; mass = 2 kg
In this case, the radius of the wind turbine blade is 52 m, and it is rotating at 0.3 rev/s, which means that the angular velocity is:
ω = 2π * f = 2π * 0.3 = 1.884 rad/s
where f is the frequency or revolutions per second.
The linear velocity at the end of the blade can be calculated as:
v = r * ω ⇒ 52 * 1.884 ⇒ 98.088 m/s
radius = 52 m
Centripetal force = (2 x 98.088²) / 52
Centripetal force = 7384.80 N
Therefore, the centripetal force on the end of a 52 m wind turbine blade rotating at 0.3 rev/s with a mass of 2 kg is 7384.80 N.
